iTween用法与常见问题-526互联

iTween oncomplete回调不工作

iTween.MoveTo (newBoom, iTween.Hash 
    "y", 100f,
    "speed",Boomspeed,
    "EaseType",BoomeaseType,
    "LoopType",BoomloopType,
    "oncomplete","BoomComplete"
    ));

// ...
void BoomComplete(){
    print("complete");
}

解决方法：添加 `oncompletetarget` 参数，给出回调对象:

iTween.MoveTo (newBoom, iTween.Hash(
    // ...
    "oncomplete", "BoomComplete",
    "oncompletetarget", gameObject
    ));

为iTween指定特定的回调: onupdate, oncomplete
找到 void CallBack, 修改如下代码：

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) {      // ADD CODE HERE !
            ((Action)tweenArguments[callbackType]).Invoke();
        }else if (tweenArguments[callbackType] is Action<object>) { // ADD CODE HERE !
            ((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);
        }
    }
}

修改后的使用方法如下:

iTween.MoveTo(gameObject, iTween.Hash(
    "x", x,
    "y", y,
    "time", t,
    "easeType", iTween.EaseType.easeInCubic, 
    "oncomplete", (Action)Landing));
    
void Landing() {
    // TODO
}
