How to call objects instance name with string? as3

Question

    private function DropFunc (e:MouseEvent):void

    {

        if(e.currentTarget.hitTestObject(Object (e.currentTarget + "Target")))
        {
            trace("good")
        }
        else{

        e.currentTarget.x = startPosX;
        e.currentTarget.y = startPosY;
        e.currentTarget.stopDrag();
        }

If I understand your question/code sample correctly, you're trying to dynamically access an instance by name.

Instead of attempting to cast it as an Object, you need to access it as a property of the parent:

private function DropFunc (e:MouseEvent):void
{

    if(e.currentTarget.hitTestObject(this[e.currentTarget.name + "Target"]))
    {
        trace("good")
    }
    else{

    e.currentTarget.x = startPosX;
    e.currentTarget.y = startPosY;
    e.currentTarget.stopDrag();
    }

}

The above example assumes that this is the parent of an object with the instance name of e.currentTarget.name + "Target".

I tried what you said, but here is the error : Property [object MovieClip]Target not found on Stage_30 and there is no default value. at Stage_30/DropFunc(), maybe it's because that that there is nothing on the stage , i am calling it from class. (They are only in library)

I apologize for my oversight. You would want to reference the currentTarget's name. I've made an update to the code above.

Thanks, i suppose that works but another problem still exist, ReferenceError: Error #1069: Property park_mc.NoFishing_mcTarget not found on Stage_30 and there is no default value. at Stage_30/DropFunc() <<< it can't find this movieclip on the stage, I am sure that NoFishing_mcTarget does exist in park_mc (notice that park_mc is not on the stage... how can i let him see it ?)... what should i do now ?

Without a complete understanding of your project, there's no real way for me to help you debug your issue. I would have to know how you're adding objects to the display list, and how/where DropFunc is being added as an event listener.

you can call the property of an object with string in the following way.

objectInstance["property"].
