You need to learn to interpret what you are reading guys.
You guys are already complaining about lag, imagine what would happen if every brick had physics functions...
I am talking about the Bricks, not the Engine as a whole. If every brick had it's own set of physics functions then trust me, Blockland would never see more than a thousand bricks again.
Try spawning 1000 jeeps, go ahead, try it. Doesn't work does it? Imagine your bricks were all smaller jeeps, try spawning 1000 smaller jeeps, doesn't work does it? No, it lags to panda.
Do you understand where I'm going or should I draw pictures of jeeps and smaller brick jeeps?
Also, vehicles wouldn't bounce. Besides, bricks fly off based on how hard they are hit. If that's not physics, I don't know what is.
Those are objects with no boundary boxes or anything, they can fly through other objects unhindered, don't bounce, don't do anything particularly special. They don't have allot of "physics" really.
