为 iTween 指定特定的回调 : onupdate, oncomplete

问题地址：Specifying a delegate for the value of onupdate in iTween

 

1、找到 void CallBack

2、修改以下代码：

void CallBack(string callbackType){

    if (tweenArguments.Contains(callbackType) && !tweenArguments.Contains("ischild")) {

        //establish target:

        GameObject target;

        if (tweenArguments.Contains(callbackType+"target")) {

            target=(GameObject)tweenArguments[callbackType+"target"];

        }else{

            target=gameObject;    

        }

        

        //throw an error if a string wasn't passed for callback:

        if (tweenArguments[callbackType].GetType() == typeof(System.String)) {

            target.SendMessage((string)tweenArguments[callbackType],(object)tweenArguments[callbackType+"params"],SendMessageOptions.DontRequireReceiver);

        }else if (tweenArguments[callbackType] is Action) {

            ((Action)tweenArguments[callbackType]).Invoke();

        }else if (tweenArguments[callbackType] is Action<object>) {

            ((Action<object>)tweenArguments[callbackType]).Invoke((object)tweenArguments[callbackType + "params"]);

        }else{

            Debug.LogError("iTween Error: Callback method references must be passed as a String!");

            Destroy (this);

        }

    }

}

3、用法如下：

iTween.MoveTo(gameObject, iTween.Hash(

    "x", x,

    "y", y,

    "time", t,

    "easeType", iTween.EaseType.easeInCubic, 

    "oncomplete", (Action)Landing));

    

void Landing() {

    // TODO

}
