Transform.InverseTransformDirection

설명

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.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    private Vector3 relative;
    void Example() {
        relative = transform.InverseTransformDirection(Vector3.forward);
        Debug.Log(relative);
    }
}

설명

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

This operation is unaffected by scale.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    private Vector3 relative;
    void Example() {
        relative = transform.InverseTransformDirection(0, 0, 1);
        Debug.Log(relative);
    }
}
