<brief_description>
Rigid body node.
Physics Body whose position is determined through physics simulation in 3D space.
</brief_description>
<description>
Rigid body node. This node is used for placing rigid bodies in the scene. It can contain a number of shapes, and also shift mode between regular Rigid body, Kinematic, Character or Static.
This is the node that implements full 3D physics. This means that you do not control a RigidBody directly. Instead you can apply forces to it (gravity, impulses, etc.), and the physics simulation will calculate the resulting movement, collision, bouncing, rotating, etc.
This node can use custom force integration, for writing complex physics motion behavior per node.
This node can shift state between regular Rigid body, Kinematic, Character or Static.
Character mode forbids this node from being rotated.
As a warning, don't change RigidBody's position every frame or very often. Sporadic changes work fine, but physics runs at a different granularity (fixed hz) than usual rendering (process callback) and maybe even in a separate thread, so changing this from a process loop will yield strange behavior.
