Request: Sprites

Post by Argh »

I got a texture atlas working for P.O.P.S., and this is good- fast particle system + texture atlas = very powerful. I think it's about ready to replace CEG's CSimpleParticleSystem for most things, and I'm working on making it a bit easier to use.

Problem is, all of a sudden I have a need for 64 really high-quality sprites for explosions and other purposes, and have discovered, to my chagrin, that I maybe have half that, in terms of stuff that's really good and generally useful. It's actually kinda sad, in a way; I got so used to having to keep the number of unique types down in CEGs that I kept it down to a ruthless minimum, and now I suddenly want variety.

So I made a whole bunch of generic flame / explosion bits, good 3D-feeling smoke and some other stuff. IOW, most of the hard stuff's done (not that I will cry if somebody really feels like executing excellent painterly smoke lit at a 45-degree angle from above, or fireballs that have the right color ranges for decent fire and well-made alpha... but really, that stuff isn't fun, and I'm happy with what I've got).

And OFC I can use all the stuff that's GPL that's good- I'll probably be raiding CA here in a bit.

However, all that's nice... but it still leaves me short. So... since I'm going to release all of this when it's done and there's a complete collection, along with the latest build of P.O.P.S. ... I thought I'd ask and see if people would like to contribute.

What I do I need: static explosion representations that can work with gentle alpha-shifting to create complex effects, i.e. stuff like this:
ImageImage
Ideally, I'd like at least one, if not two color-matched sets of 8 like these, with alpha channels set up (ideally) but I'd be more than willing to do that part (it's a little tricky with this type, due to the use-case).

Other stuff- splats or blobs, electrical stuff, things that feel like "plasma", maybe some rendered shell casings at different angles, but lit from forward / above?

Anyhow, if anybody feels like contributing anything, post it here. Technically so long as the sprites are square, they'll work, but the real spec (i.e., what P.O.P.S. will auto-shrink it to) is 128X128, which is still big enough for quite a lot of detail, so I'd like stuff in that size, if possible.

Anyhow, I figured it might be a fun thing for somebody to kill a couple of hours with, to make a set, or twenty minutes to make a single thing.

And who knows? Maybe I'll get enough stuff to need a second atlas. This whole atlas thing really makes it possible to have a heck of a lot of sprites, after all.

Ah, had fun with the CA stuff, here are a few things I poked (just put color into alpha, done, or wait for the TGAs).

Anyhow, gotta go for a bit, hope people feel like participating :-)

Well, we have this in the 1944 SVN if it helps at all...

You could probably find some good ones in other OSS games - OpenArena for example, if you're willing to use GPL content.

Voh from TAU made a nice little tool to create explosion sprites with a particle based system, I don't know how far he's come with it but you might consider asking him about it.

I'm not really looking for animated stuff atm. I'm more interested in doing some fake-volumetric stuff where I need stuff that is prelit, like what I showed- the main explosions in P.U.R.E. were all done that way, and with more variety to the bitmaps, I should be able to convey a huge amount of apparent detail. I'll start working on the color-matched sets.
