through bugs in a game i was making (2d) i have found that certain colors do not collide properly, especially primary and secondary colors. for example, my green (0,255,0) ship did sense collision with a magenta(255,0,255) powerup. the colors, since they have nothing in common, they pass right through each other. check out this lil' snippet i made to demonstrate the problem. this only really matters with pure color sprites, but its still a wierd bug. i just changed the colors by adding a little bit to the other colors to get around it. anyone else ever run into this?

Truth suffers from too much analysis.

Yah, thats strange, it does that with every color (that I have tested). As they say, DBC's 2d engine wasn't that developed. Or was it 3d? I can't remember anymore.

No I've never run into this. When I use anything 2D, I use the make object plain command and then just texture it. I found that works better for colliding. And, I usually never color my stuff. That is weird though, so I'll try it to see if that happens to me 2.

I know, but you can give the effect of 2D using plains, and I believe the collision are more accurate, and you can pass of your game as 2D.

I don't see a problem with it. You can load the background like that, you can even make a 2D side-scrolling mario with the plains like I said.
