OnDemandRendering.willCurrentFrameRender

描述

如果当前帧将被渲染，则为True。

using UnityEngine;
using UnityEngine.Rendering;

// This example shows how to determine if the current frame will be presented to the screen.
public class Example : MonoBehaviour
{
    void Start()
    {
        QualitySettings.vSyncCount = 0;
        Application.targetFrameRate = 60;
        OnDemandRendering.renderFrameInterval = 3;
    }

    // Output will be:
    //
    // Will this frame render? False
    // Will this frame render? False
    // Will this frame render? True
    // Will this frame render? False
    // Will this frame render? False
    // Will this frame render? True
    void Update()
    {
        Debug.Log("Will this frame render? " + OnDemandRendering.willCurrentFrameRender);

        if (!OnDemandRendering.willCurrentFrameRender)
        {
            // Frames that are not rendered may have some extra CPU cycles to spare for processes that would otherwise be too much of a burden.
            // For example: expensive math operations, spawning prefabs or loading assets.
        }
    }
