RigidBodyType

The simulation behaviour of a RigidBody.

• dynamic — fully simulated: moved by gravity, forces, and collisions. The simulation owns the transform; it is written back onto the host every frame.
• fixed — immovable. Never integrated, infinite mass. The right choice for static level geometry (ground, walls).
• kinematic-velocity — moved only by a velocity you set; unaffected by forces or collisions, but pushes dynamic bodies out of its way. The simulation advances it and writes the result back to the host.
• kinematic-position — moved by directly steering the host transform; the body follows the host into the simulation and shoves dynamic bodies. The host owns the transform (you set host.position / host.rotation), and the body is driven from it. Use this to script the motion of a platform or door that still needs to collide.
