在 Unity 中，如何判断是否是第一次打开游戏? [英] In Unity, how to tell if it's the first time a game is being opened?

问题描述

我想要一个脚本来运行，

I want a script to run,

每当我在 Unity 中的游戏第一次打开时.

whenever my game in Unity is opened for the first time.

推荐答案

使用 PlayerPrefs.检查密钥是否存在.如果key不存在，返回默认值1，即第一次打开.另外，如果这是第一次打开，将该键设置为 0，这样就不会再返回 1.因此，任何not 1 的值意味着它不是第一次打开.在这个例子中，我们可以调用键 FIRSTTIMEOPENING.

Use PlayerPrefs. Check if key exist. If the key does not exist, return default value 1 and that is first time opening. Also, If this is first time opening set that key to 0 so that if will never return 1 again. So any value that is not 1 means that it is not the first time opening. In this example we can call the key FIRSTTIMEOPENING.

if (PlayerPrefs.GetInt("FIRSTTIMEOPENING", 1) == 1)
{
    Debug.Log("First Time Opening");

    //Set first time opening to false
    PlayerPrefs.SetInt("FIRSTTIMEOPENING", 0);

    //Do your stuff here

}
else
{
    Debug.Log("NOT First Time Opening");

    //Do your stuff here
}
