replacement textures

If you want to see replacement textures... replace the game.zip... game/textures/ folder with the one in the above link.

The sky texture was not replaced. That was on purpose cause sky is all fucked up anyway.

edit (unrelated): I just got water scrolling. Nothing special. Just a place-holder animation that I can upgrade later.

Added skybox support


edit:
for shitz and giggles I compiled new lightmaps that look more like they belong with the source


The skybox is loaded based on a field in worldspawn.

[MadGypsy]

How do I determine which lights effect which faces so I can color the light?

[MadGypsy]

anybody know where I can find some .lit file specs?

[Baker]

Supposed this engine tutorial works

Quake Standards Group - Tutorial

Otherwise you will likely need to examine gl_model.c. It's a short header and the 3 bytes for every 1 byte that was in the .bsp for lighting.

Looks like the file starts "QLITxxxx" and then that data (i.e. the 8th byte is the start of the data), where xxxx is 4 bytes that comprise a 32-bit (signed) integer.

[MadGypsy]

oh sweet! thank you!

so startLightData = 9th actual byte and endLightData = (totalbytes -?

The only reason I'm asking is because I have found gaps in bsp bytes. I actually read struct results, and header_t offset/length values don't add up to every byte in the file.

ex:

header
header.entitites[0] 46218 [1] 415
header.planes[0] 124 [1] 3520
header.miptex[0] 46637 [1] 68268
header.verts[0] 5072 [1] 4176
header.vislist[0] 45865 [1] 349
header.nodes[0] 9248 [1] 2616
header.texinfo[0] 11864 [1] 3200
header.faces[0] 15064 [1] 5240
header.lightmaps[0] 31074 [1] 14787 = 45861
header.clipnodes[0] 20304 [1] 2416
header.leafs[0] 3644 [1] 1428
header.lfaces[0] 22720 [1] 674 = 23394
header.edges[0] 28470 [1] 2540
header.ledges[0] 23398 [1] 5072
header.models[0] 31010 [1] 64

so startLightData = 9th byte and endLightData = (totalbytes - 8 )?

I suppose I have a C programmer mindset where indexes start at 0, so 0-7 is the first 8 bytes.

But yeah, that's right.

[MadGypsy]

Indexes start at 0 for me too. I edited my post before I realized you replied to say "9th actual byte."

edit: I for real and truly program in over 15 languages and I don't think any of them are 1 based. Can anybody name a 1 based language? I can't. They supposedly exist, hence the term "1 based" but, it must be obsolete or summin cause, no modern language that I am aware of is 1 based.

edit2: I found this. I have heard of exactly one 1 based language in that list (SASS). I programed in sass once to test it's css expansion functionality. I think it was SASS, anyway. Some language with an ass in it.

edit3: It was definitely SASS. It even means Syntactically Awesome Stylesheets. Basically, you write very concise stylesheets using a very similar syntax to css and then run the compiler. Your sass gets expanded to valid css.

[MadGypsy]

Hmmm, there must be something else to this because, the lit file is only 11090 ints in length but, my lightdata is 14787.

I have no doubt that i am reading it exactly how you said

private static function _lightmap():void
{	$lit.position = 8;

	$lightmap = new Vector.<int>(($lit.length-8)/4);
	$lightmap.forEach(function(na:int, n:int, self:Vector.<int>):void{
		self[n] = $lit.readInt();
	});
}

[Baker]

Read int?

Light data is not int (int32 = 4 bytes), it is bytes.

rgb data is going to be 3 bytes each, compared to the original which will be 1 byte each.

Maybe you were thinking rgba. But isn't rbga, it's rgb.

[MadGypsy]

I see how I misunderstood. You said 4 bytes as signed int. Well, readInt is 4 bytes and that's a signed int.... See what I'm saying?

I understand now.

[Baker]

The 8 byte header contains a single int32.

The data after the 8 byte header is rgb.

I said QLITxxxx, the xxxx is int32. That part is a read int. Not the light data itself.

[MadGypsy]

woops...lol


I know what I fucked up. I need to take 30 and come back to this. My engine was not prepared for this extra data and apparently I'm going to need to do the full surgery to get this to work right.

edit: You would think with as much stuff as I fuck up and straight up don't know/understand, it is a miracle I have gotten this far. Spike all but grabbed me by the collar "Linear filtering, dumb-ass!" LMAO! That shit still isn't linearly filtered. I'll learn AGAL another day. I'm banging out the stuff that is far more involved than a shader script. Actually shader scripts might be the last thing. I need a bilinear filter and a water caustics, hardly seems worth it right now.

Actually, if you follow this thread and consider what it really takes to do each part you can see how I am walking through my API from basic to advanced. I'm not just learning how to parse BSPs, I'm learning how to use this 3d engine api too. I'm doing all of this from a stance of ideas...trial and error, and LOTS of reading docs. Did I mention that Away3D docs suck donkey balls? It's the exact format as the AS3 docs (which is awesome) but there isn't a single fucking example. If I didn't know AS3 Away3D would be completely unusable, to me.

[MadGypsy]

Let me guess, I'm not gonna get away with this part without a shader? I am rendering the lit file out exactly how I would lightdata but with 3 vars instead of 1. It would seem that this also expects to be combined with the original light data.

[Spike]

the header is "QLIT\1\0\0\0". reject it if those 8 bytes don't match. otherwise skip over them and pretend that they're not there.

lit files entirely replace the original lighting lump with 3*8bit lighting instead of 1*8bit lighting.
the surfaces lump remains unmodified of course, which means you need to ensure that the surf->lightofs value is correctly scaled up to the new *3 byte offset.
most engines just use full rgb lighting, with non-lit support just being a case of trippling each byte of the bsp's greyscale lighting data.

and yeah, you still need linear filtering. you also need mipmapping with your world/high-res textures (lightmaps don't need it, and the atlasing can make it glitchy). hop to it.
