public function AddRelativeForce(force: Vector3, mode: ForceMode = ForceMode.Force): void;
public void AddRelativeForce(Vector3 force, ForceMode mode = ForceMode.Force);

Parameters

force Force vector in local coordinates.

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.

public function AddRelativeForce(x: float, y: float, z: float, mode: ForceMode = ForceMode.Force): void;

Parameters

x Size of force along the local x-axis.
y Size of force along the local y-axis.
z Size of force along the local z-axis.
