Unity本身有PlayerPrefs来做一些数据的保存和读取,也可以通过循环来做批量的读取或者保存,下面这个脚本可以方便的调用用来做上面批量的工作,比如读取一组文本数组数据和保存一组文本数组数据.
建议把这个脚本放在Standard Assets目录下,这样可以按照下面的方法方便的调用它.现在包含了下面这些命令:
PlayerPrefsX.SetVector3
PlayerPrefsX.GetVector3
PlayerPrefsX.SetIntArray
PlayerPrefsX.GetIntArray
PlayerPrefsX.SetFloatArray
PlayerPrefsX.GetFloatArray
PlayerPrefsX.SetStringArray
PlayerPrefsX.GetStringArray
保存一个向量
static function SetVector3 (key : string, value : Vector3) : boolean
[code=js]//尝试保存一个物体位置
var player : GameObject;
if (!PlayerPrefsX.SetVector3("layerPosition", player.transform.position))
print("不能保存物体位置!");[/code]
成功返回真,否则假(例如用Webplayer保存超过1M数据的时候).
获得一个向量
[code=js]var player : GameObject;
player.transform.position = PlayerPrefsX.GetVector3("layerPosition");[/code]
如果读取的向量存在的话将会返回这个向量值.
保存一组整型数据
[code=js]//当保存Scores命名的分数时候创建一个10成员数组
var myScores = new int[10];
for (i = 0; i < myScores.Length; i++)
myScores = i+1;
if (!PlayerPrefsX.SetIntArray("Scores", myScores))
print("不能保存分数!");[/code]
获得一组整型数据
static function GetIntArray (key : string) : int[]
如果存在将返回这组数据,否则将返回int[0];
[code=js]var scores = PlayerPrefsX.GetIntArray("Scores");[/code]
static function GetIntArray (key : string, defaultValue : int, defaultSize : int) : int[]
如果不存在这组数据,将返回指定长度的数组以及每个成员都会赋予默认值.
其他函数的使用方法:
static function SetFloatArray (key : string, value : float[]) : boolean
static function GetFloatArray (key : string) : float[]
static function GetFloatArray (key : string, defaultValue : float, defaultSize : int) : float[]
static function SetStringArray (key : string, value : String[]) : boolean
static function SetStringArray (key : string, value : String[], separator : char) : boolean
static function GetStringArray (key : string) : string[]
static function GetStringArray (key : string, separator : char) : string[]
static function GetStringArray (key : string, defaultValue : String, defaultSize : int) : string[]
static function GetStringArray (key : string, separator : char, defaultValue : String, defaultSize : int) : string[]
