Direct access object to a physics body in the [Physics2DServer].
</brief_description>
<description>
Direct access object to a physics body in the [Physics2DServer]. This object is passed via the direct state callback of rigid/character bodies, and is intended for changing the direct state of that body.
Provides direct access to a physics body in the [Physics2DServer], allowing safe changes to physics properties. This object is passed via the direct state callback of rigid/character bodies, and is intended for changing the direct state of that body. See [method RigidBody2D._integrate_forces].

<description>
Applies a positioned impulse to the body. An impulse is time independent! Applying an impulse every frame would result in a framerate dependent force. For this reason it should only be used when simulating one-time impacts (use the "_force" functions otherwise). The offset uses the rotation of the global coordinate system, but is centered at the object's origin.
