Description
|
|
-----------
|
|
|
|
Provides direct access to a physics body in the :ref:`Physics2DServer<class_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 :ref:`RigidBody2D._integrate_forces<class_RigidBody2D_method__integrate_forces>`.

|
|
void **apply_impulse** **(** :ref:`Vector2<class_Vector2>` offset, :ref:`Vector2<class_Vector2>` impulse **)**
|
|
|
|
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.
