Add startDrag & stopDrag methods for Sprites about starling-framework

[PrimaryFeather]

I must say I'm no longer sure this is really necessary, since dragging can be achieved as simple as the following:

sprite.addEventListener(TouchEvent.TOUCH, onTouch);

private function onTouch(event:TouchEvent):void
{
    var target:DisplayObject = event.target as DisplayObject;
    var touch:Touch = event.getTouch(target, TouchPhase.MOVED);

    if (target && touch)
    {
        var movement:Point = touch.getMovement(this);
        target.x += movement.x;
        target.y += movement.y;
    }
}

This was more complicated in the past, when there was no getMovement() method. But now — it seems very simple; and most of the time, you need to adapt the code somehow, anyway, so the default implementation wouldn't cut it for you.

Are there more opinions on this?

So long time... We need this feature!

@illuzor useful troll mode why startDrag() but not startBlink()?

[PrimaryFeather]

Wow, it's been a while since I opened up that issue! ;-)
Since I never got any feedback of developers requiring it, it's quite low down in my priorities-list, though I still think it would be useful.

However, I recommend you have a look at the "TouchSheet" class that's used in the Starling Demo. It implements a complete multi-touch-enabled drag solution (plus pinch and rotate), so it's for sure a good starting point for what you want to achieve.

PrimaryFeather, thank you for answer.
Of course task may be solved via many ways, but built-in feature will be much more comfortable.

[PrimaryFeather]

Of course! I just want to avoid that you have to wait for me to implement this before you can continue. ;-)

[illuzor]

I have solved the task. I am understand that implementation can`t be immediate.
We are just waiting. Thank you!

Still waiting :)

+1 for waiting

[illuzor]

I`m agree. No need for dragAndDrop now

[Eketol]

Thanks PrimaryFeather, that worked for me!

[PrimaryFeather]

Perfect, thanks for the feedback!
I'll close this issue then.
