Description 描述

An exception thrown by the PlayerPrefs class in a web player build.

在网页版由PlayerPrefs类抛出异常。

The exception is thrown when writing to a preference file exceeds the allotted storage space. The storage space is 1MB for a web player. This exception is not thrown on other platforms.

当写入存档文件超过所分配的存储空间时，抛出异常。在网页版储存空间为1MB。在其他平台不会抛出这个异常。

JavaScript:

#pragma strict
function Start() {
	// create a one megabyte character string
	var s16 = "0123456789abcdef";
	var s1024 = "";
	for (var j = 0; j < 64; j++)
		s1024 += s16;
	var s1024x1024 = "";
	for (var i = 0; i < 1024; i++)
		s1024x1024 += s1024;
	// try to save the string (it will fail in a webplayer build)
	try {
		PlayerPrefs.SetString("fail", s1024x1024);
	}
	// handle the error
	catch(err: System.Exception) {
		Debug.Log("Got: " + err);
	}
}
