Hmm, how do you make a box that is on ALL 3 layers?

That might lag stuff a little, nah, I'd rather make the other bricks non-collidable in the same layer.

Buildism has no lag. I can spam 1000 blocks in Grey world and it still runs 100%.

3 blocks isn't gonna do anything. Manually putting stuff in layers is something you learn is more efficient when making a full game. (because if your script has a hole, you will have to do a lot more work)

Yea, but a machinegun that fires 20 rounds per secound would. 20*3 = 60 bricks per second.

That still wouldn't lag...
A script calculating the position of a block and it's layer takes up more CPU than having 3 static blocks.

But the blocks aren't static. The move in one direction constantly.

You want the missiles to be on all 3 layers?
Simple, put everything on one layer.

I don't think the missile should logically collide with anything in front or behind it.
