使用ITweenX 來簡化iTween外掛程式的函數調用，itweenxitween

iTween外掛程式是u3d中很火的動畫外掛程式。

但是幾乎所有函數的參數都是字串，函數名也要以字串的方式傳入，這就不好了，我們沒有必要去記EaseType和其他的參數串。

對於  設計模式的要求是  多組合，少繼承。多擴充，少修改。

由於這個外掛程式本身的功能沒有任何問題。所以我們沒有必要做任何徒勞的重構。就是擴充就玩了唄。

使用：

把指令碼放進Standard Assets/Scripts 等等檔案夾中即可; 這也很容易被javascript 或 Boo語言使用. 如果你聲明一個 public 的EaseType類型變數, 你能夠很容易的設定easetype 在面板 inspector. 上。

例子，隨便調用一個方法：

public class MyClass: MonoBehaviour{public EaseType easeType; void Start(){iTween.ValueTo( gameObject, iTween.Hash( iTweenX.from, 0f, iTweenX.to, 1f, iTweenX.time, 1f,                                                 iTweenX.onUpdate, "OnUpdateValue",                                                 iTweenX.onStart, "OnStart",                                                 iTweenX.onComplete, "OnComplete",                                                 iTweenX.easeType, iTweenX.Ease(easeType),                                                 iTweenX.ignoreTimescale, true ) );}void OnUpdateValue(float value){ print( "OnUpdateValue : " + value.ToString() ); }void OnStart(){ print( "OnStart" ); }void OnComplete(){ print( "OnComplete" ); }}
