Transform.InverseTransformDirection

Switch to Manual
public function InverseTransformDirection(direction: Vector3): Vector3;

Description

Transforms a direction from world space to local space. The opposite of Transform.TransformDirection.

This operation is unaffected by scale.

You should use Transform.InverseTransformPoint if the vector represents a position in space rather than a direction.

// transform the world forward into local space:
private var relative : Vector3;
relative = transform.InverseTransformDirection(Vector3.forward);
Debug.Log(relative);

public function InverseTransformDirection(x: float, y: float, z: float): Vector3;

Description

Transforms the direction x, y, z from world space to local space. The opposite of Transform.TransformDirection.

This operation is unaffected by scale.

// transform the world forward into local space:
private var relative : Vector3;
relative = transform.InverseTransformDirection(0, 0, 1);
Debug.Log(relative);
