@kinloch Well, as I said in OP, I'm looking for simulation/engineering sandboxes. Redpower/Computercraft are no go for me as they require Forge and I am not ready to dump water shader mod.
There is a game called Rigidchips where you can build things with chips using a script system or you can download a program called Rigidchips Designer to build visually.
@tudoreleuu(View Post) That's what I thought when I first tried it :P. You design things 2D on a simple blueprint, and then simulate it in a 3D environment. The sandbox uses bullet physics I think.
btw lol, you inserted a comma in your precentage instead of a decimal, xD seems like you understand it really well!
