Transform.TransformPoint

# [Transform](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform.html).TransformPoint

public [Vector3](https://docs.unity3d.com/cn/2019.4/ScriptReference/Vector3.html) **TransformPoint** ([Vector3](https://docs.unity3d.com/cn/2019.4/ScriptReference/Vector3.html) **position**);

## 描述

将 `position` 从本地空间变换到世界空间。

注意，返回的位置受缩放影响。如果要处理方向矢量，请使用 [Transform.TransformDirection](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform.TransformDirection.html)。

可以使用 [Transform.InverseTransformPoint](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform.InverseTransformPoint.html) 执行从世界空间到本地空间的反向转换。

```
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public GameObject someObject;
    public Vector3 thePosition;

void Start()
    {
        // Instantiate an object to the right of the current object
        thePosition = transform.TransformPoint(Vector3.right * 2);
        Instantiate(someObject, thePosition, someObject.transform.rotation);
    }
}
```

public [Vector3](https://docs.unity3d.com/cn/2019.4/ScriptReference/Vector3.html) **TransformPoint** (float **x**, float **y**, float **z**);

## 描述

将位置 `z`、`z`、`z` 从本地空间变换到世界空间。

请注意，返回的位置受到缩放的影响。如果要处理方向，请使用 [Transform.TransformDirection](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform.TransformDirection.html)。

```
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public GameObject someObject;

void Start()
    {
        // Instantiate an object to the right of the current object
        Vector3 thePosition = transform.TransformPoint(2, 0, 0);
        Instantiate(someObject, thePosition, someObject.transform.rotation);
    }
}
