Unity3D: iTween oncomplete not working

Question

I am working on a Unity2 game, and I want to make Boom disappear in the end of iTween animation.

Here is part of code

void OnMouseDown() {    

    if (ChosePosition == false)
        ChosePosition = true;

    // make Star stop
    else if (ChosePosition == true && ChoseForce == false) {
        ChoseForce = true;
        //Compute Force power 
        PowerDegree = Mathf.Abs (Star.transform.position.y - StarPosition)/ Mathf.Abs(StarendPosition - StarPosition) * 100;

        //print (PowerDegree);

        Vector3 NewBoomPostion = new Vector3 (Luncher.transform.position.x, BoomPosition, 85);

        GameObject newBoom = Instantiate(Boom, NewBoomPostion , Quaternion.identity) as GameObject;
        iTween.MoveTo (newBoom, iTween.Hash 
            ("y",BoomPosition+((BoomendPosition-BoomPosition)/100*PowerDegree),
            "speed",Boomspeed,
            "EaseType",BoomeaseType,
            "LoopType",BoomloopType,
            "oncomplete","BoomComplete"
            ));


        CarrierReset = true;
        ChosePosition  = false;
        ChoseForce = false;

        //After Shot, Luncher will move
        iTween.Resume(Luncher);

        //After Shot, Luncher Carrier will display
        displayCarrierOrNot = true;
    }
}


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

But I can't see "complete" in console.

Thanks for your suggestion, I put parameters in multiple line. If I get rid of those quotes, it will throw invalid argument error. — rj487, Sep 15 '15 at 06:39
I was wrong about trying to pass the method itself--the capitalized local variable/field names confused me into thinking you were already doing that with other methods. But I found a new answer that I'm fairly sure should help. — 31eee384, Sep 15 '15 at 06:45

This post on Unity Answers describes why you have the problem:

By default iTween attempts to call the callback methods you provide it on the object it is animating - in your case the mainCamera.gameObject. Since "onCameraShakeComplete" does not reside on that object it is never getting called. You have two options: Move that method onto your mainCamera.gameObject or simply provide am "onCompleteTarget" of gameObject to tell iTween to use the GameObject that is setting up this iTween.

In your case the object it is animating is newBoom, but you have the callback on your own component. To make iTween use your current callback you can add a parameter to your Hash call:

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

This helped me today, thanks 6 years later! – lerichard_v Dec 03 '21 at 03:50 — lerichard_v, Dec 03 '21 at 03:50
