particles in front of something white seems to turn invisible like in this screenshot:

thats a bit of a problem since most of the textures in my game are compoletely white, so i jsut wanted to know if there is a way to make the particles not turn invisible in front of white textures.

maybe you set its BRIGHT flag that results in additive blending, thus it can't be not white over white background.

that fixed it. however now the particles are very dark in the edges and it doesnt look as good.

is there a way to make it look like before without the BRIGHT flag?

set their TRANSLUCENT flag and tweak their alpha to fade out.

the TRANSLUCENT flag is already set and it is also fading out. is there anything else that can be done?

here is my code if it can help

Code:

function part3(PARTICLE* p)
{
	p.green = 0;
   p.red = 255;
   p.blue = 0;
   set(p, MOVE | LIGHT | TRANSLUCENT);
   p.alpha = 100;
   p.size = 30;
   p.gravity = 0;
   p.skill_a = 16; // fade factor
   p.event = p_fade;
}

Then you have to create a better particle bmap, for instance as follows

(probably not free to use)

and control the transparency with the alpha channel (do not add black to the flame texture).

I'm wondering if there is a way to set a particle's draw layer. The sample in the manual seems to appear in front of everything else on my level...

overlay might help, it takes the first pixel top left and turns all of the same color transparent.

Don't use overlay. Use an alpha mask.

Like -Feindbild said just use a alpha channel. Here is my test scene and the particle tga I made for it.
