Has anyone created any siege weapons or castles to attack using these new physics? I was just messing around in an atempt to create a box throwing catapult, the only problem is it works in reverse. I.E it throws the box away from the rotational point instead of over it. Any ideas on why this is?

the exact reason why catapults have a basket

so that the basket edges hold the objects inertial forces until they are directed straight forward from the basket...but you may also notice that the basket is never drawn beyond the horizon...i will show quick paint sketch for you brb.

I would think you need to make a stop at the end the box is and to make the pivot point larger.

make the model near to a real one my work like one.

if you did what you have for real like a rule a drinks can and a box of some thing and then did as in the sim hit the other end it would probably fly off the same way.

Dark Physics makes any hot drink go cold.

After adding a really ghetto basket I've got something going. Goes about 500 feet on a straight path, doesnt look pretty though. Ill post it up here after I tweak some other stuff.
