PlayerPrefsEx

---

Note:

There are limitations on PlayerPrefs in webgl:https://docs.unity3d.com/2022.1/Documentation/ScriptReference/PlayerPrefs.html (opens new window)

1. The total data of PlayerPrefs cannot exceed 1MB
2. The data of a PlayerPrefs entry cannot exceed 1MB

If PlayerPrefs already stores 1MB of data, setting PlayerPrefs.SetInt("t",1) will fail because the total will exceed 1MB. If PlayerPrefs does not have any data, PlayerPrefs.SetString("t2","ttttt-----") can store 1MB of data at a time.

Set

	describe
UnityEngine.PlayerPrefsEx.SetFloat(key,value,back)	key: string value:float、number back：Callback function, parameter is bool type. Like c# Action true : success false : fail If you don't care about the result, callback can be omitted.
UnityEngine.PlayerPrefsEx.SetString(key,value,back)	key: string value:string back：Callback function, parameter is bool type. Like c# Action true : success false : fail If you don't care about the result, callback can be omitted.
UnityEngine.PlayerPrefsEx.SetInt(key,value,back)	key: string value:int back：Callback function, parameter is bool type. Like c# Action true : success false : fail If you don't care about the result, callback can be omitted.
UnityEngine.PlayerPrefsEx.SetFloatArray(key,value,back)	key: string value:float[] back：Callback function, parameter is bool type. Like c# Action true : success false : fail If you don't care about the result, callback can be omitted.

Get

	describe
UnityEngine.PlayerPrefsEx.GetFloat(key,back)	key: string back：Callback function, parameter is bool type. Like c# Action The return value in Lua is number If the value does not exist or the type does not match, the result is number 0
UnityEngine.PlayerPrefsEx.GetString(key,back)	key: string back：Callback function, parameter is bool type. Like c# Action The return value in Lua is string If the value does not exist or the type does not match, the result is string "null"
UnityEngine.PlayerPrefsEx.GetInt(key,back)	key: string back：Callback function, parameter is bool type. Like c# Action The return value in Lua is number, which is an integer. If the value does not exist or the type does not match, the result is number 0
UnityEngine.PlayerPrefsEx.GetFloatArray(key,back)	key: string back：Callback function, parameter is bool type. Like c# Action<float[]> The return value in Lua is number, which is an single. If the value does not exist or the type does not match, the result float[] length =0

Del

	describe
UnityEngine.PlayerPrefsEx.DeleteKey(key)	key: string
