  175. - void **add_central_force** **(** :ref:`Vector3<class_Vector3>` force **)**
  176. Adds a constant directional force without affecting rotation.
  177. This is equivalent to ``add_force(force, Vector3(0,0,0))``.
  178. ----
  179. .. _class_PhysicsDirectBodyState_method_add_force:
  180. - void **add_force** **(** :ref:`Vector3<class_Vector3>` force, :ref:`Vector3<class_Vector3>` position **)**
  181. Adds a positioned force to the body. Both the force and the offset from the body origin are in global coordinates.
  182. ----
  183. .. _class_PhysicsDirectBodyState_method_add_torque:
  184. - void **add_torque** **(** :ref:`Vector3<class_Vector3>` torque **)**
  185. Adds a constant rotational force without affecting position.

  194. 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. The position uses the rotation of the global coordinate system, but is centered at the object's origin.
