Networking

I've started to look into the networking code for Dune. While I'm currently still in a phase of trying things out in a sandbox environment, I will work on the networking code from now on. Once that's in, I will add the other missing features in Dune.

I initially read a few articles on other (commercial) RTS games and how they did their networking. For instance, Age Of Empires used a Peer-to-peer setup to communicate with all the other players. The game was a perfect simulation on each client. They accomplished this by make the game 'turn-based'. The player input would be registered, packed up and send to all clients. Each action would be executed in a turn, and when the data was send out to all the other clients, it used current turn + 2. So, when the current turn was 1000, and the player wanted a villager to go and chop down a tree, the actual ordering would happen in turn 1002. Since turns only lasted 200ms each, the player wouldn't even notice the delay between clicking and seeing the action.

However, in such systems, it's problematic when lag is 500ms: A packet send with orders scheduled for turn 1002 would arrive during turn 1003. AOE would adopt to this by either halt the game(In severe cases), or stretch up the time needed for each turn. In the case of 500ms lag, it would increase the turn time to 250 or 275ms, giving each packet more time to arrive.

This seemed to work well(I tried AOE2 to test it out) and it ran like a charm. So, I wanted to implement a similar to that of AOE2. However, setting up a P2P network between clients is a pain in the ass. Esp. when you take NAT into consideration. The system would have to work like this:
- Each client connects to host
- On start game, the host opens a series of new ports, one for each client.
- Each client connects to this port and disconnects directly
For each client:
- The host sends all other clients to which other client they should connect by handing out the IP and port number.
- The clients connect to the other player since the NAT port is now opened up

- Host is done when all players are connected to eachother.

It's quite complex, and I'm not sure if it would even work. Perhaps I should give it another shot and try to set it up. Once it works, it should work like a charm.

Bugtracker update #2

It's been a while since I updated... I've been really busy. Since the summer vacation begun, I found myself a summer job. Right now I'm a system administrator at a large company. My job is to check out how Windows Vista will fit in the existing environment and how the group policies behave in them, since Vista doesn't eat the older formats. I also have to take over the responsibilities of the other system administrator when he's off on vacation.

I just continued with experimenting with bug trackers. I tried to install Trac, and failed. The reason: It seems it can create an sqlite database, but no matter where I try to create it, it just fails. If I create it in the root of the C drive, it fails with the error Access Denied, and if I use an existing directory, it screams that I can't create a new directory(Well duh!). So I gave up.

One of the biggest downsides of Trac is that it requires quite a lot of external dependencies. In order to run, you either need a running Apache configuration with CGI / FastCGI / mod_python installed. You need sqlite(Since MySQL is very experimental. And to be honest, I don't like to run experimental stuff on my development environment).

So: Bugzilla is left. I've decided not to install / try any paid trackers, since those are outside my budget anyway.

One a sidenote: I did have some more time with Mantis this week. Even tho it lacks SVN integration, it's still a pretty nice system. I like it, and if Bugzilla doesn't behave better, I'll go with Mantis and setup a SVN integration system. I can't remember the name right now, but it's capable of glueing Mantis / Bugzilla to SVN.

Bugtracker update #1

I haven't done a whole lot of research on bugtrackers in the past days, but that's because I've been doing some other things aswell(Like snowboarding the entire day. Yes, in the middle of the summer.). However, I can do some reporting on things I've done.

First of all, I installed Mantis. Since I already had an instance of Apache running, I could just install PHP for it, install MySQL and voila, done. After that I added a few bugs to the system to see how it works and looks.

A few downsides of Mantis:

• Documentation on the site is lacking
• The My View is kinda cluttered
• Not possible to assign a bug directly to a developer while reporting it(Actually, you can, but you need an advanced report for that)

But, it also has a few nice features:

• Easy to install(Just open the index page)
• Detailed report information
• Multiple projects in 1 database
• Projects can be made (in)visible to certain users, users can have roles in projects

So far, I like Mantis. But, I still have to look into a glue system to glue it into SVN(Which is out there), since it's pretty nice to be able to link repos updates directly to bugs.

I also made a start with installing Trac, but that requires quite some more work...

Counting the credits

I implemented the credits counter today. It's a simple little UI component that I managed to whip up in about 1.5 hours, including sexy 'animation'. After setting the credits, it compares the amount with the visible credits. In then calculates the difference between the 2 and divides that by 2(seconds). During each frame update, it multiplies the pre-calculated value with the deltatime and voila, you get to see an update animation.

It's not exactly like the original, that seemed to rotate around, but that's too much work to implement for now.

The credits counter in the top right

I'm also looking into using a bugtracker. Right now I'm using the SVN commit logs to document bugs, but that's not the most efficient way. So using a bugtracker might help with bugs that I intend to fix on a later date. As for now, I keep forgetting to document all the bugs, remember them AFTER the commit and write them down. And then lose the note with the bugs.

So, I'm looking at Mantis and a few others, and I'll make my decision soon(probably tomorrow). After I fixed my server... Yes, fixed... I decided to remove a bunch of server roles which I installed for testing purposes. However, after I removed the Terminal Server role it had to reboot. After the reboot I could no longer login remotely, so I'm trying to fix that now.

Carry-alls and harvesters... An excellent combination

Today I added in all the goodness for carry-alls to pickup harvesters and deliver them into the refinery. It was quite some work to get that working, since I had to code in a few extra special cases(is this a harvester, does it have clearance for the refinery, is the landing area actually the refinery, etc.). But, now harvesters DO get picked up by a carry-all, if around, and they'll fly em into the refinery. And flying is SO much faster than driving :).

Carry-all just picked up harvester enroute to spice field.

Also, a newly built refinery now will receive a free harvester, which is dropped off in style by a carry-all, which will depart immediatly after dropping off the harvester. After the carry-all leaves the onscreen boundaries, it will delete itself.

Fully loaded harvester being returned to refinery

The carry-all which delivers the reinforcements into the field is a little special carry-all, namely a ReinforcementCarryall. I wrote a special class for it, since I didn't want to implement the code for leaving the field in the regular carry-all. That would really pollute the code. Also, this new Carry-all makes it possible to have regular reinforcement drops too, which is pretty sweet. Including stuffing 20 units into it.

But, there's a little issue with the carry-alls right now: When a tile is used, it won't be able to drop off it's payload, and just keeps hanging there, until the tile becomes free. So, that's what I'm going to solve next: find a free tile and unload there.

I already wrote a similar thing for the harvester to find spice tiles, so I'm considering to make it a general helper class and use a generic Comparable kind of thing. It's code that won't be called too often so speed isn't a really big issue here. And added goodness is that I can 'smear' out the search over multiple frames. In the case of finding a spice field which needs 200 steps to be found, it will cause severe lag. Being able to do this is say, 40 frames, it will only be 5 steps per frame, and therefor no big deal.

After this works, I'm going to fix a little bug with the selection rendering, constructing and then finally implement the credit counter control.

Spice must flow!

And flow it will! I spent the weekend implementing harvesters and refineries. Right now, a harvester is capable to driving to a spice field, happily seperate the spice from the sand, find a refinery, drive back and enter the refinery. Once in, the refinery will empty the harvester, provide credits to the player and when the harvester is empty, it will deploy it.

Our initial state: Idle harvester and refinery

Most of the harvesting code is still the same as it was before, but I also changed quite a lot. Most of the changes are in the refinery, which now has a 'landing zone', the area where the harvester has to land in order for the spice to flow. Initially it used the building coordinates to find it's way into the refinery, but this meant the harvester would drive to the center of the building. Also, I updated the images concering the harvester and the animation, so they use up less VRAM(Altho it came with a dirty hack: I have to figure out in which directions to displace the animation, otherwise it looks dislocated)

The harvester is collecting spice

When a harvester is full, it will request a list of all known refineries. It will traverse this list and attempt to find the most suitable refinery. That is, with the shortest queue or no queue at all. When it comes by an idle refinery, it will stop searching. When it has found a refinery, it will inform the refinery that it's enroute, lay out a path and start it's dangerous journey back home(Esp. when no carry-alls are around). The refinery will now start 'blinking' it's landing zone(when idle), or otherwise just queue up the harvester.

Harvester returning to the refinery, which has a blinking landing pad

When the harvester has reached the refinery, it will wait for clearance. The clearance means the refinery is ready to receive the harvester and refine whatever goodness it brings. When the harvester receives it's clearance, it will roll onto the landing zone and remove itself from the scene. This is important, because it will otherwise keep rendering itself, which will look weird: A harvester ontop of a refinery with a harvester in it. The refinery stores the harvester internally, so when the refinery is destroyed, it will automatically destroy the harvester aswell.

Refinery processing a harvester

It takes 35 seconds for a fully loaded harvester to unload(20 credits per second). When done, a harvester will ALWAYS be deployed, even when a carry-all is signaled to pick it up. This is done because it might take a while before the carry-all arrives, and when deployed, it gives other harvesters the chance to enter the refinery. This was something that annoyed me in the original game: When a harvester was waiting for a carry-all to arrive, it took a while, so other harvesters had to wait, while I was already low on cash.

To do:
- Have harvesters return back to the spice field
- Limit the number of tiles searched for new spice
- Harvester spice dunes first, then normal spice
- Fix bug related to tiles not being free'd
- Have a carry-all unload the harvester into the refinery
- Have carry-alls bring a harvester to a newly placed refinery

Epic debug sessions

I'm currently busy with some epic debug to fix a some major bugs in the movement code. It suffered from units running over other units, where the unit that was being ran over disappeared. It still rendered, but it no long accepted orders, could be selected, etc. I also had units that would not clear tiles they occupied properly, so that in some cases, tiles were still used while the unit was half a map further, which led to other units behaving strangely when driving. And last, units sometimes 'jumped' to other tiles and started vibrating. Yes, vibrating... No idea what causes that.

I fixed in the past week the run overs, which is nice. By fixing this, I haven't seen units warp since I fixed that, nor vibrate. So it seems that I only need to fix the clean up. I made a nice function which runs a check on the entire map and shows which tiles are used by what unit, and if this unit is actually positioned on that tile. And if not, it shows a [ERROR] tag. In combination with the debug log I hope to find out where it goes wrong.

After this works, I'm gonna make units 'defend' themselfs from others. ie, if attacked, they'll start attacking their attacker.

Let the vehicle construction begin!

I got unit construction in. Wasn't a lot of difficult work. It basically was adding an additional check to the techtree retrieval function, and if a tech item was a unit, place the icon in the Unit strip, and otherwise the building strip.

The rest of the system is the same: The building asks the ConstructionManager if there's a job waiting for him, and if so, it takes the order and executes it. When done, it will now check what kind of object is done. If it's a unit, it will check if there's a free spot around the building, and if yes, it will deploy the vehicle there. When there are no more tiles free around the building, it will show a nice message in the debuglog telling me to implement carry-all's to pickup tanks from buildings(Which is actually really friendly).

I still have to implement showing a deployment animation when a unit is deployed, but that's not that difficult. It's a matter of minutes to implement the additional class(ConstructionBuilding) and the code to trigger the animation.

The next step is to give each unit / building a unique ID which is also linked to it's owner. I'm running into some nasty bugs, which makes debugging difficult if you got 20 units on the screen and 1 flips out...

Bugs I have at the moment: When a unit runs into an obstacle along it's path, it will try to find a new route. If it can't find one(Because the blocking object is the end-tile), it suddenly changes it's position to 1 tile back and starts vibrating... Very odd.

The other bug is related to units popping their states off the stack for no apparant reason. That only happens when moving in groups tho, so I need IDs to track them.

Units after their construction

To do for next time:
- Add IDs for units and buildings
- Fix movement bug
- Fix state popping bug
- Add deployment animation
- Add icon sorting to the construction bars. It's annoying to have the order change depending on how you build the buildings(Or if you lose your barracks half way) and the icons end up in the bottom.

Bug fixes, loads of them!

While technically still in development I hunted down and squashed a load of bugs in the past few days. Having a laptop and being able to work in the train is awesome. Every now and then I see people take a peak at my screen to see what I'm doing. Earlier this week there was a guy who just kept looking at my screen, and back outside, back to the screen, etc. Esp. when I fixed a little thingy and ran the game again to see how the changes worked out.

First, the list of bugs I managed to strangle(For those not interested, skip down, there's imagery there).

• Fixed bug where buildings would be placed 1 tile to the left and 1 tile up
• Lowered scrolling threshold to be Tile.Size / 2(So scrolling only happens on the edges, instead of 1 complete tile)
• Fixed bug where you could order buildings to move/attack(Would cause crash)
• Dragselection rectangle / Building placement rect don't show up when hovering over UI components
• Renamed Radar to Outpost(Needed for Reflection to work)
• Fixed bug where placement rectangle would be rendered OVER UI components while while the mouse was outside the component
• Buildings can no longer be added to the building manager of a different owner
• Fixed debug log text
• Added a little bit more debug output
• Fixed an issue where the CheckMouseOver() function would read out of bounds
• Fixed an issue where the mouse handling code would respond to mouse clicks in the UI

As for the new feature: I added concrete slabs. Not very special as you can see below, but still, it's in. I think the next step to this is to allow buildings to build units. After that I think it's time for refineries to 'order' a harvester reinforcement.


I also noticed that the revision number updates weirdly... I have a pre-compile step which runs an svn lookup batch file to determine the revision of the repository, turn that into a sexy class with getter and store it all. However, it doesn't always(read never) run when compiling. Pretty weird, and annoying. Probably only runs on a full re-compile, so I usually just run the batch file manually after commiting my code. Not the best solution, but it works.

I also started committing more often, since I used to do too much work between commits. If my laptop would either explode or get stolen, I would probably lose a week or 2 of work. Not really that appealing...

Building placement is in

In the past 2 days I put the code together for placing buildings on the map. While not completely done yet, I also found a few bugs in the code relating to writing to the debug console, finding items on the map and the techtree.

I'll be going to fix these issues before adding in the construction of vehicles and implementing the credits counter. But after I cleaned up the input handling code.

First some screenshots:

Debug console display we started building a new WOR. Note the 'built by' bug.

Placement of our new building not allowed here, see debug console for next error

And voila, our new building is placed, including sexy deployment animations(Not included)

The next step is moving all the input code into the LocalPlayer class. Hooray for .NET partial classes, since this will prevent my code from turning into a huge pile of steamy mess that could make even the most seasoned developer cry himself to sleep.

After that, I will first fix all the bugs I've found till so far and then I'll implement the placement of concrete(yay!), the penalty of placing a building without concrete and construction of vehicles. If those work, I'm considering implement a basic network framework(!!!) and then start polishing up basic features. When these features are implemented (Which will take a while), I have a basic playable RTS.

Construction is in... Now building placement

Over the past few weeks I've slowly implemented construction of buildings. It's possible to now select a build icon from the sidebar and add it to a construction queue. Each building checks every update cycle(But only when idle) if there's a queued up item, it takes from the queue and starts 'building' it.

When done, it informs the player object about it, which can then take the appropriate action. A human player will see a message / hear a sound and an AI will place it directly.

I'm currently working on implementing the building placement. However, I still don't know how to fully implement it. I currently have a GameInputHandler which handles that part of the input(Do the picking, context sensitive cursor, etc.). But, I need to change it around to be less, messy.

Also, I've been thinking about adding a feature for hearing impaired. One of my current projectmates for a college project is deaf, and one of his biggest issue with most RTS games is that he never gets a message about that his base is being raped. (He usually notices that he's getting his ass kicked when it's too late...) Well, there is a warning, but without working hearing, he can't hear it. So I want to add an optional screen message, which blinks in the middle of the screen. Simple to add, and usefull for those who can't use sounds or can't hear. Having people in your projectgroup which have a minor disability widens your view a bit.

I am an idiot, srsly

I'm an idiot. A huge idiot. Remember how I reported about rolling out 2 Draytek Vigor 2800G routers? Turns out I ordered the wrong routers. A 400 euro mistake.

The routers I ordered come with a built-in modem, and all snazzy features that the router has, are done on the WAN interface(The modem). But, Versatel doesn't allow their customers to replace the modem with one of their own and the new line that was in the new office was an SDSL line. So none of the routers can be used.

I'm trying to order the Vigor 2910 now, which is used to cable(And therefor, has a WAN interface where an RJ-45 plug fits in). I'll contact a reseller to see if it works on the SDSL line and Versatel, and if so, see if I can get a hold of them today and roll them on tomorrow(Which was supposed to be a day off)...

Idiot...

Problem solved, and the lack of updates

I'll kick off with some good news: I solved the issues with the weird rendering of vertices. I got the advice to toggle some of the important and basic D3D feats off/on to make sure it all didn't get messed up.

I decided to walk the list of D3D renderstates and pick the ones I knew and change them to be off. This was lightning, Z-Buffer, CullMode and FillMode. Turns out, the z-buffer was the problem. So now i know where the problem lies, I can continue to work on the issues at hand.

However, there is a reason for the lack of updates: I'm very busy at the moment with school and my business. For school we have program a robot, and most of the hardware of the bot was dead. So we got new hardware, and need to update all the code to work with the new hardware, re-write all the PIC controllers(They burned out, and no source was avaliable) and implement new features too. And I got a few clients that demand my attention aswell.

Tomorrow I will be delivering 2 Draytek Vigor 2800G to a client. And these things are pretty sweet. They support up to 32 simultaneous VPN connections, protocol blocking, content filtering, url filtering and they're wireless too. It's pointless for home usage(As they're 200 euros a piece), but for a business, it's pretty sweet stuff.

Some minor issues...

I'm currently having weird issues rendering linestrips... I noticed this week that the drag selection wasn't rendering anymore, so I went to search what the cause of this was.

I still have no idea what causes it, but the more I test, the stranger the results: After a a reboot or running another DX application, it now shows a filled triangle(As it should), which it is striped. However, when I move my self-rendered cursor over it, it disappears.

Restarting the application doesn't work, it just doesn't show up. Pretty weird... I asked on GDNet, hoping they can help me out....

Almost a game...

Today I merged the UI code with the Gamestate code. And lo and behold: Something that looks like a game.

Almost a game, almost.

I discovered there is something severely messed up(I nearly wrote fucked up) with my Post-Build step. It doesn't update the revision in the bottom of the screen properly. It probably has to do with TortoiseSVN and it not going a proper update after the commit. Because if I do an update after the commit and recreate the file, it works like a charm. Pretty weird.

Also, I'm thinking about how I am going to handle building of stuff. First of all, I need something that manages buildings. We shall call this the BuildingManager. The BuildingManager contains a list of all buildings in possession of the player. When a building is destroyed, it will remove it, etc. Also, I need something to uniquely ID the buildings across the network(Yes, I'm also thinking about). So, each building will have an unique identifier, which is nothing more but a sequential integer.

When a building is being constructed, the BuildingManager will receive it's application and store it. It will then return the unique identifier to the building and inform the network about a newly constructed building. When it is the first building of it's kind, it will also contact the ConstructionManager. The construction manager will look in TechTree and see if there are any changes needed. If for instance the building just placed is a construction yard, it will see that after a construction yard has been built, the slab and windtrap will be unlocked. It will then add these to the construction sidebar.

For a networked game, there will be a RemoteBuildingManager(RBM) and a RemoteConstructionManager(RCM). The RCM will not schedule any construction, it will only pass the order to the correct building. The LocalConstructionManager(LCM) however, will find an idle building and post the build order there to be completed. This has the added pro of the game being able to check if a player is using hacks(Because, it can see how long it takes before the next build order arrives. If the remote player has an instant build hack, it can see that the player still has to wait for the construction to be completed).

So, still a lot of work to do, and I'll start out with the techtree loader tomorrow.

Hello Arrakis!!

I added some more features to the Windowing system, and I think I'm done for now with the system. All that remains are the controls to be written, and I'll write those as soon as I need them.

Features I've added:
- Complete rendering of the borders and title bar
- Client rectangles(Client Rectangle = Window - borders)
- Dragging of windows
- Move event for when the window is being dragged around

The dragging of the window was quite some work, as I needed to change quite a lot of code. It wasn't very difficult, just required a lot of code changing, since I never wrote the code to be able to drag the windows around, nor intend to have borders around it them(Pretty stupid).

This initially ended up with the Control class drawing itself on the wrong position while being dragged, and the derived class draw on the correct position. Pretty weird, and I still have no idea why this happened. The image below shows this in action(I had to place my fingers in a really uncomfortable position to be able to get this pic. My left hand pink and ring finger held down the FN + ALT key, while my thumb help down the L-mouse on my touchpad, my index finger drew circles on the touchpad and my right hand was used to pressed Print Screen).

Dragging bug in action, nearly lost my fingers while obtaining this image

After I fixed the dragging bug, I'd figured I'd make a standard dialog window(Not yet written, but the code needed for it is ready, just need to be moved into another class). This is what it looks like:

Standard dialog with label and button

How does the dragging system work?
When the L mouse down event is catched, it checks if the mouse is over a window. If this is true, it will check if the mouse is within the ClientRectangle. If this isn't the case, it checks if the Y is within the bounds of the TitleBar. If this is true, it will record the state as Dragging for the LMouse button, and which control it is dragging.

On every mousemove, it checks if the LMouse is down, and when this is the case AND the state is dragging, it takes the Delta X and Y and substracts this from the position of the window. It then forces to update all the client rectangles and voila, done.

New control
I added a Label control. Not very special, it took like 2 minutes to create...

Todo for now:
- Create a MessageBox class.
- Add support for modal windows
- Incorporate UI into existing game class.
- Build CreditCounter control(Dune specific)
- Layout new todo list for building, techtree, etc.

Also, to answer a previously asked question about open-sourceness:
For now, I will keep the source closed. This is a personal project, and I don't take kindly to people changing my code while I'm still working on the game. However, after the game is completed, I might open-source it. However, I might, might release my UI system, in case people want to take a look at it, and perhaps improve it. It's not the best system out there, there are MUCH better UI systems out there, but it works for a small amount of controls.

Image strips are in... And update on dialogs

Today I managed to add the images into the imagestrip. The image strip is the little strip that holds all the icons of the units/buildings you can make, and allows you to scroll through it.

It was rather simple to implement, except I ran into 2 little problems: The original images that were used in the original Dune for the imagestrip end up HUUUUGE when enlarged. So I scaled them up 2 and then reduced them to 66% of their size. That worked quite well(As you will see below).

After that it was a matter of painting the green bar between the 2 images and fit a few images in. Fitting the images in wasn't very difficult, except that was were the other problem was: The icons Stefan provided with his Dune 2 image set were too small. Increasing them in size turned out horrible. Really horrible. Loads of artifacts and they were pretty pixelated.

So I had to find a way to extract the images myself. This was rather problematic, as I had no idea which of the PAK files contained these images, and only 1 PAK file contained the palette files. I downloaded XCC Utilities and started messing around, but I was unable to load a palette after loading a new PAK file.

Eventually I extract the palette file, made copies of the MENTAT.PAK and FINALE.PAK. I then opened up XCC editor and placed the palette file into both these files and saved them. I then loaded up FINALE.PAK and MENTAT.PAK into XCC mixer and discovered that mentat had all the images, but that finale.pak also had a bunch. Duplicates that is, since all these images were also in mentat.pak. I have no idea why there were 15(!!) duplicates in the FINALE.PAK. These images(All just 1 frame) were the sardaukar, death hand, fremen, refinery, MCV, sand worm and a few others. When I looked in mentat.pak, I fould all the images, with their animations.

I extracted these files, and converted them into icons. The icons are 52x32 in size. If anyone wants these, for whatever reason, let me know, and I'll upload them. I also have to extract a few other files from the dune.pak file, since these are missing(I think I'm missing 1 missile impact animation and the burning/burned out tank).

Right now I need to update the image strip so that clicking is supported, it's possible to mask out all the images except 1(The building animation, not sure how I'm going to do that with multiple construction queues) and I need to fix the windows and their title-bar/border drawing.

The UI in action, showing the image strip(Scrolling works) and a window with title bar

I also need find a better way to render client areas of Windows. Right now they are textures. That's a a massive waste of VRAM, so I need to fix that. I'm probably going to use quads for the client area and just cram them into a VertexBuffer and render all the client areas at once. Not sure how that will work out, but I'll experiment with it. Alternatively, I could just create 1x1 textures with the correct background color, and rendered them stretched. Don't know which one is less work and/or cheaper to do in terms of performance.

More gooey goodness...

Ok, f this. I just spent 30 minutes writing up an entry about my awesome progress with in-depth details of decisions, backgrouns and other information, and then Firefox decided to crash.

When I restarted it, it recovered the session, but the entire post was gone. And apparantly, clicking 'Recover post' does nothing, except show up a messagebox that it will replace the post with an older version. WHAT OLDER VERSION?

Here's an image of the UI in action: A button with the mouse over it and the left mouse button down. Hooray, BOOOOORING! And yes, I'm annoyed now. Really annoyed. Annoyed as in I want to break something. And yes, I have anger management issues. It's a miracle I never killed someone.

A really not very exciting image with a button responding to a mouse down event. Tee hee

It's my birthday...

So yeah, I turned 24 today. Nothing special, just a funny cat. Also, I have no time to code today.

Still working on the UI....

Yes, I am working on the UI stuff. I got the events sorted out, and I'm right now working on rendering the system controls and the window bar. Nothing special to see right now.

To keep you guys happy, here's a cat. DuneCat
