	<brief_description>
		Direct access object to a physics body in the [Physics2DServer].
	</brief_description>
	<description>
		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].

	<methods>
		<method name="add_central_force">
			<return type="void">
			</return>
			<argument index="0" name="force" type="Vector2">
			</argument>
			<description>
				Adds a constant directional force without affecting rotation.
			</description>
		</method>
		<method name="add_force">
			<return type="void">
			</return>
			<argument index="0" name="offset" type="Vector2">
			</argument>
			<argument index="1" name="force" type="Vector2">
			</argument>
			<description>
				Adds a positioned force to the body. Both the force and the offset from the body origin are in global coordinates.
			</description>
		</method>
		<method name="add_torque">
			<return type="void">
			</return>
			<argument index="0" name="torque" type="float">
			</argument>
			<description>
				Adds a constant rotational force.

		</method>
		<method name="apply_central_impulse">
			<return type="void">
			</return>
			<argument index="0" name="impulse" type="Vector2">
			</argument>
			<description>
				Applies a directional impulse without affecting rotation.
			</description>
		</method>
		<method name="apply_impulse">
			<return type="void">
			</return>
			<argument index="0" name="offset" type="Vector2">
			</argument>
			<argument index="1" name="impulse" type="Vector2">
			</argument>
			<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.
			</description>
		</method>
		<method name="apply_torque_impulse">
			<return type="void">
			</return>
			<argument index="0" name="impulse" type="float">
			</argument>
			<description>
				Applies a rotational impulse to the body.

			<return type="Variant">
			</return>
			<argument index="0" name="contact_idx" type="int">
			</argument>
			<description>
				Returns the collided shape's metadata. This metadata is different from [method Object.get_meta], and is set with [method Physics2DServer.shape_set_data].
