WebGL Doom

"Suppose we should really push the latest stuff to github" Edition (TM)
The biggest change here is the addition of the 'world buffer', an offscreen render target that all the walls, flats, things and such are rendered into. This has some benfits such as pre-z calculation so we don't waste too much time doing work fancy pixels that you'll never see.

Supposedly should give a nice performance boost in theory but that doesn't seem to be the case, infact on Firefox at least it seems to have slowed it down even more. So while we are killing performance how about we go all the way and really butcher the framerate? Dynamic Lights and Screen Space Ambient Occlusion (SSAO)!

The Dynamic Lights are for missle projectiles only so far, but there is no reason why we couldn't detect certain THINGS that could emit light, like the slime barrels and the little light stalks that litter the levels. Currently the Dynamic Lights are hardlimited to 32.

SSAO is a subtle but awesome effect, you can toggle it using the . key, keep an eye on the edges and corners of the walls and floors. Yeah, told you it was subtle but now you've seen it, quite effective isn't it ;) Just ignore the huge hit to your FPS =P

Other bits
- Fixed(ish) projectiles getting stuck in the air.
- THINGS update stack now more efficient.
- THINGS now use a cylindrical billboarding style.
- Probably some other fixes.

It looks like a lot more was done as the diff is HUGE, this is pretty much just because I decided to get a bit stricter on the code style and virtually every line has been changed as a result =P

Oops, been awhile since we've updated here.
- Split game.js into seperate files, much more readable and managable now
- Updated to latest features in HE3D engine
- Added HUD/Statusbar stuff.
- Moved the debug keys to z,x,c,v,etc. The number keys are for weapons*.
- THINGS angle correctly... mostly
- THINGS have gained some intelligence now, they'll turn and shoot at you if you get close enough.
- Fixed ALPHA on wall textures
- Projectiles!
- Heightmap is gone, using the BSP sector check now.
- Fixed some missing sprites
- Reworked lighting, now works on THINGS.
- Added some parsing code for audio support, not ready for use yet
- Added animated FLATS
- Sprite name lookup is way faster now
- Probably a lot more
* No you still can't fire the weapons yet =P

Heightmaps should transfer a bit better now as it doesn't try to upload the map as a texture (this was crashing Chrome on E1M8).

Added some better collision detection against the heightmap, its still very wrong but at least you shouldn't fall through the world too much now. Also moved the players position and movement code into it's own thing instead of using the camera. We now have fake gravity and mouse movement.

Added some visual lines to see which THINGS are being considered for what will be collision testing later on. (Press 6 to toggle).

Heightmaps! Crazy over the top heightmaps to be precise. "Thats not the way Doom did it!". I thought I'd try out rasterising the FLATS into a massive array for a per-pixel based heightmap. There is a good chance this might cripple or crash your browser, I've only really tested it on an i7 =P

As a result, the THINGS are in the right places now and in theory could move around (when I get to that stage), in the mean time YOU can walk around in there now, I've done some quick thrown together Doom style controls (yes disabled looking up and down ;))

There is no friction for the walls or anything yet, so you will get stuck in walls at some angles, hopefully you can back out of them if not, use the freecam mode (F key) to fly out of there

I've seen Chrome crash a few times on the bigger maps (due to the size of the heightmap it needs to transfer back) like E1M8 so ymmv on workyness

THINGS! are now rendering animated in their spawnstate.

THINGS! (Doom's name for the 2d sprites you see on the map). These are now rendering in their spawnstate and don't animate or move yet, that will probably be the next stage. They also always face the camera, which is correct but not the best way of drawing them. Ideally they would only rotate on one axis, if you fly the camera above and look down you will notice they are flat on the ground. This is the Mario64 way of billboarding.
