Re: Character standing on a moving vehicle

maybe try first,calc the correct force to rigidbody,then calc vehicle local space move force to rigidbody
you can look the raycast vehicle ,how to calculate wheel fraction force .like the force by different velocity of two rigidbody,fixed force like this will solve the character on a moving vehicle

Hinge2 vehicle deviate of the center vector

i made a hinge2 vehicle,but when i give the wheel a big motor force and a high target velocity,the vehicle will deviate . if i want to avoid this,can some one tell me how to do this?i search the forum for answer ,but i failed. this deviation will happen strongly when i breaking the vehicle and set v...

btHinge2Constraint why anchor move offset the parent axie

i test a btHinge2Constraint,use constraintDemo,when i set all angular limit to zero,the anchor is in the parent axie,but when i set the x axie angular limit to allow the body rotate,the anchor will move offset the parent axie?why ,and how can is avoid this. btRigidBody* pBodyB = localCreateRigidBody...
