Transform.InverseTransformDirection 变换反方向

# [Transform](Transform.html).InverseTransformDirection 变换反方向

function *InverseTransformDirection* (*direction* : [Vector3](../Vector3/Vector3.html)) : [Vector3](../Vector3/Vector3.html)

*Description* 描述

Transforms a direction from world space to local space. The opposite of [Transform.TransformDirection](Transform.TransformDirection.html).

变换方向从世界坐标到自身坐标。和 [Transform.TransformDirection](Transform.TransformDirection.html) 相反。

This operation is unaffected by scale.

此操作不受缩放影响。

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

```
// transform the world forward into local space:
//变换世界向前坐标变为自身坐标
private var relative : Vector3;
relative = transform.InverseTransformDirection(Vector3.forward);
Debug.Log(relative);

• function *InverseTransformDirection* (*x* : float, *y*
: float, *z* : float) : [Vector3](../Vector3/Vector3.html)

*Description* 描述

Transforms the direction x, y, z from world space to local space. The
opposite of [Transform.TransformDirection](Transform.TransformDirection.html).

变换方向 x, y, z 从世界坐标到自身坐标，和 [Transform.TransformDirection](Transform.TransformDirection.html) 相反。
