Fastest way to clear a surface? SOLVED

[Toxicosis]

I'll make it quick, I need to clear a surface, i.e., take every pixel in it and replace its r,g,b,a by 0,0,0,0, as if it had been just created. What's the easiest way to do so, short of freeing the surface and creating another?

I think this is the function you need.
draw_clear_alpha(c_black,0);
Changing the alpha to 1 will change the surface into a black rectangle.

That'll do. Thanks!

That isn't a valid way to clear a surface.
Read this for why.

Ah, damn. I keep forgetting surfaces may contain noise.
OK, will use draw_clear_alpha.
