Transform.TransformPoint

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。

可以使用 Transform.InverseTransformPoint 执行从世界空间到本地空间的反向转换。

If you need to transform many points at once consider using Transform.TransformPoints instead as it is much faster than repeatedly calling this function.

See Also: Transform.TransformPoints, Transform.TransformDirection, Transform.TransformVector.

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);
    }
}
