This node implements simulated 2D physics. You do not control a RigidDynamicBody2D 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 RigidDynamicBody2D has 4 behavior [member mode]s: Dynamic, Static, DynamicLocked, and Kinematic.
+ You can switch the body's behavior using [member lock_rotation], [member freeze], and [member freeze_mode].
[b]Note:[/b] You should not change a RigidDynamicBody2D'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.
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].
- The center of mass is always located at the node's origin without taking into account the [CollisionShape2D] centroid offsets.

[b]Note:[/b] Don't change a RigidDynamicBody3D'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 may result in strange behavior. 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 function. See [member custom_integrator].
- With Bullet physics (the default), the center of mass is the RigidDynamicBody3D center. With GodotPhysics, the center of mass is the average of the [CollisionShape3D] centers.
