Rigidbody.AddRelativeForce

Parameters

Description

Adds a force to the rigidbody relative to its coordinate system.

Force can be applied only to an active rigidbody. If a GameObject is inactive, AddRelativeForce has no effect.

Wakes up the Rigidbody by default. If the force size is zero then the Rigidbody will not be woken up.

See Also: AddForce, AddForceAtPosition, AddRelativeTorque.
