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

问题描述

我要运行脚本，

当我第一次在Unity中打开游戏时.

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.如果密钥不存在，则返回默认值 1 ，这是第一次打开.另外，如果这是第一次打开，请将该键设置为 0 ，这样，如果再也不会返回 1 .因此，任何不是 1 的值都意味着不是是第一次打开.在此示例中，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
}
