Transform.TransformPoint

Description

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。

可以使用 Transform.InverseTransformPoint 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);
    }
}

Description

将位置 z、z、z 从本地空间变换到世界空间。

Note that the returned position is affected by scale. Use Transform.TransformDirection if you are dealing with directions.

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);
    }
}
