场景中UI始终朝向相机

挂在需要看向摄像机的UI物体上

脚本如下：

public class lookatCamera : MonoBehaviour {

private Camera Camera;

public bool reverFace = false;

private Transform thisRoot;

private void Awake()

{

//获取该物体与相机

if (!Camera)

{

Camera = Camera.main;

}

thisRoot = transform;

}

private void Update()

{

Vector3 targetPos = thisRoot.position + Camera.transform.rotation * (reverFace?Vector3.back:Vector3.forward);//确定位置方向

Vector3 targetOrientation = Camera.transform.rotation * Vector3.up;旋转角度

thisRoot.LookAt(targetPos, targetOrientation);朝向

}

}
