unity 检测物体是否在相机视野范围内

脚本挂在摄像机要显示的对象上

前提：该对象有 render 组件

public class visibleTT : MonoBehaviour
{
public bool isRendering = false;
public float lastTime = 0;

public float curTime = 0;

void Update()
{

if (lastTime != curTime)
{
isRendering = true;
Debug.Log("In View");
}

else
{ isRendering = false;
Debug.Log("Not In View");
}

lastTime = curTime;

}

void OnWillRenderObject()
{

curTime = Time.time;

}

}
