Hello,
I’m new to Godot and I really like the nodes concept.
I’m trying to do a small car “sim” with a RigidBody3D(box) on 4 RayCast3D
that may sound silly but after days of headaches, I decide to seek for help
I’m very confused with how to use apply_force().
Could anyone help me understand ?
void apply_force ( Vector3 force, Vector3 position=Vector3(0, 0, 0) )
=> with position as the offset from the body origin in global coordinates.
- position = body origin + local offset (all in global coordinates) ?
or
- position = body origin (global coordinates) + local offset (local coordinates) ?
the only way i can make it “work” is by doing :
- apply_force(- wheel_node.transform.basis.z * force , wheel_node.position)
wheel_node.position => which is local offset from the car body ?!
but, when the car has rotated 180, every force applied is inverted ?!
(without applying any torque force)
Thank you.
