This node implements simulated 2D physics. You do not control a RigidBody2D directly. Instead you apply forces to it (gravity, impulses, etc.) and the physics simulation calculates the resulting movement based on its mass, friction, and other physical properties.
A RigidBody2D has 4 behavior [member mode]s: Rigid, Static, Character, and Kinematic.
[b]Note:[/b] You should not change a RigidBody2D's [code]position[/code] or [code]linear_velocity[/code] every frame or even very often. If you need to directly affect the body's state, use [method _integrate_forces], which allows you to directly access the physics state.
If you need to override the default physics behavior, you can write a custom force integration. See [member custom_integrator].
Please also keep in mind that physics bodies manage their own transform which overwrites the ones you set. So any direct or indirect transformation (including scaling of the node or its parent) will be visible in the editor only, and immediately reset at runtime.
If you need to override the default physics behavior or add a transformation at runtime, you can write a custom force integration. See [member custom_integrator].
