A 2D physics body that can't be moved by external forces. When moved manually, it affects other bodies in its path. An animatable 2D physics body. It can't be moved by external forces or contacts, but can be moved manually by other means such as code, [AnimationMixer]s (with [member AnimationMixer.callback_mode_process] set to [constant AnimationMixer.ANIMATION_CALLBACK_MODE_PROCESS_PHYSICS]), and [RemoteTransform2D]. When [AnimatableBody2D] is moved, its linear and angular velocity are estimated and used to affect other physics bodies in its path. This makes it useful for moving platforms, doors, and other moving objects. If [code]true[/code], the body's movement will be synchronized to the physics frame. This is useful when animating movement via [AnimationPlayer], for example on moving platforms. Do [b]not[/b] use together with [method PhysicsBody2D.move_and_collide].
