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