target | 要指向的对象。 |
worldUp | 指定向上方向的矢量。 |
旋转变换,使向前矢量指向 target
的当前位置。
随后它会旋转变换以将其向上方向矢量指向 worldUp
矢量暗示的方向。
如果省略 worldUp
参数,则该函数会使用世界空间 y 轴。如果向前方向垂直于 worldUp
,则旋转的向上矢量将仅匹配 worldUp
矢量。
using UnityEngine; // This complete script can be attached to a camera to make it // continuously point at another object.
public class ExampleClass : MonoBehaviour { public Transform target;
void Update() { // Rotate the camera every frame so it keeps looking at the target transform.LookAt(target);
// Same as above, but setting the worldUp parameter to Vector3.left in this example turns the camera on its side transform.LookAt(target, Vector3.left); } }
worldPosition | 要对准的点。 |
worldUp | 指定向上方向的矢量。 |
旋转变换,使向前矢量指向 /worldPosition/。
随后它会旋转变换以将其向上方向矢量指向 worldUp
矢量暗示的方向。
如果省略 worldUp
参数,则该函数会使用世界空间 y 轴。如果向前方向垂直于 worldUp
,则旋转的向上矢量将仅匹配 worldUp
矢量。
using UnityEngine;
public class ExampleClass : MonoBehaviour { public Transform target;
void Update() { // Point the object at the world origin (0,0,0) transform.LookAt(Vector3.zero); } }
