Hi gyes I am trying to make a catapult and have some issues i am trying to solve The catapult more or less works but there is strong jitter(at start of video) https://clipchamp.com/watch/c2ZUKATaXHe I am applying a one off angular impulse on the z axis on the 2 dark gray blocks The two dark gray blocks are connected with fixed joints to the long catapult log and with a ball & socket(x,y restricted) to the main catapult body When i apply the force the blocks get knocked out of position for a bit which causes the projectile to go in wrong direction. Is this is a good way to make a catapult using HAVOK? Are there any preferred ways to have more stable behaviour? Thanks!!
