<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" />
<argument index= "0" name= "force" type= "Vector2" />
<description >
Adds a constant directional force without affecting rotation.
</description>
</method>
<method name= "add_force" >
<return type= "void" />
<argument index= "0" name= "offset" type= "Vector2" />
<argument index= "1" name= "force" type= "Vector2" />
<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" />
<argument index= "0" name= "torque" type= "float" />
<description >
Adds a constant rotational force.
</description>
</method>
<method name= "apply_central_impulse" >
<return type= "void" />
<argument index= "0" name= "impulse" type= "Vector2" />
<description >
Applies a directional impulse without affecting rotation.
</description>
</method>
<method name= "apply_impulse" >
<return type= "void" />
<argument index= "0" name= "offset" type= "Vector2" />
<argument index= "1" name= "impulse" type= "Vector2" />
<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" />
<argument index= "0" name= "impulse" type= "float" />
<description >
Applies a rotational impulse to the body.
</description>
</method>
<method name= "get_contact_collider" qualifiers= "const" >

Returns the collider's object id.
</description>
</method>
<method name= "get_contact_collider_object" qualifiers= "const" >
<return type= "Object" />
<argument index= "0" name= "contact_idx" type= "int" />
<description >
Returns the collider object. This depends on how it was created (will return a scene node if such was used to create it).

<return type= "Variant" />
<argument index= "0" name= "contact_idx" type= "int" />
<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].
</description>
</method>
<method name= "get_contact_collider_velocity_at_position" qualifiers= "const" >
<return type= "Vector2" />
<argument index= "0" name= "contact_idx" type= "int" />
