<brief_description>
|
|
Physics Body whose position is determined through physics simulation in 3D space.
|
|
</brief_description>
|
|
<description>
|
|
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.

Called during physics processing, allowing you to read and safely modify the simulation state for the object. By default it works in addition to the usual physics behavior, but [method set_use_custom_integrator] allows you to disable the default behavior and do fully custom force integration for a body.

Apply a positioned impulse (which will be affected by the body mass and shape). This is the equivalent of hitting a billiard ball with a cue: a force that is applied once, and only once. Both the impulse and the offset from the body origin are in global coordinates.
