void Start(){ Rect screenRect = new Rect(0, 0, Screen.width, Screen.Height); } void Update{ Vector3 screenPos = targetCamera.WorldToScreenPoint(objTrans.position); if(!screenRect.Contains(screenPos)){ //do what you want Debug.log("Obj has gone out of screen..."); } }
方法一
public var isRendering:boolean=false;
private var lastTime:float=0;
private var curtTime:float=0;
function Update()
{
isRendering=curtTime!=lastTime?true:false;
lastTime=curtTime;
}
function OnWillRenderObject()
{
curtTime=Time.time;
}
