Black Particles?
by Kirby Webber · in Torque Game Engine · 01/05/2003 (7:20 pm) · 6 replies
I have been playing around with damage emitters, and I would like to define an emitter for black smoke.
From what I have gleaned, we have color[0]= r,g,b,transparency and color[1] = r.lifespan,g.lifespan,b.lifespan, and ??.
If I have this wrong, then please correct me, but what I really know is (are you gonna go my way... sorry. Couldn't help it! ;-) ) is it possible to define black? IF you drop all the rgb values to zero in color[0] you get nada. Theoretically it's there but you have told it not to render?!
I specifically remember being impressed by the grenade explosions in Tribes 2, however, they are using a few more channels on their particles than what we apparently have available.
Anyone know how to get black smoke?

I simply applied the useInverseAlpha right after the texture definition... nada. Is that what you meant?

Nope. Didn't work, at least if I used it correctly anyway.I simply applied the useInverseAlpha right after the texture definition... nada. Is that what you meant?

You could download the spaceshock demo. I specifically remember that there were black particles defined in his script that worked in the engine.

Cool, I'll do just that! Thanks.

EXCELLENT! Thanks Anthony! That does the trick! :-)
