任意摄像机开始渲染前触发的事件。
注意,当调用 onPreRender 时,摄像机的渲染目标尚未设置,深度纹理 也尚未渲染。如果您想稍后(在设置好渲染目标后)执行某些操作, 请尝试使用 CommandBuffer。
using UnityEngine; public class ExampleClass : MonoBehaviour { // callback to be called before any camera starts rendering public void MyPreRender(Camera cam) { Debug.Log("PreRender " + gameObject.name + " from camera " + cam.gameObject.name); }
public void OnEnable() { // register the callback when enabling object Camera.onPreRender += MyPreRender; }
public void OnDisable() { // remove the callback when disabling object Camera.onPreRender -= MyPreRender; } }
