1.新建一个C#脚本，命名为 “SkipSplashScreen” （代码如下）。

using System.Collections;
using System.Collections.Generic;
using System;
using UnityEngine;
using UnityEngine.UI;


#if !UNITY_EDITOR
using UnityEngine;
using UnityEngine.Rendering;

public class SkipSplashScreen
{
    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSplashScreen)]
    private static void BeforeSplashScreen()
    {
#if UNITY_WEBGL
        Application.focusChanged += Application_focusChanged;
#else
        System.Threading.Tasks.Task.Run(AsyncSkip);
#endif
    }

#if UNITY_WEBGL
    private static void Application_focusChanged(bool obj)
    {
        Application.focusChanged -= Application_focusChanged;
        SplashScreen.Stop(SplashScreen.StopBehavior.StopImmediate);
    }
#else
    private static void AsyncSkip()
    {
        SplashScreen.Stop(SplashScreen.StopBehavior.StopImmediate);
    }
#endif
}
#endif

2.将 SkipSplashScreen 脚本，放到 Assets 目录下，打包并运行！
