Troubleshooting issue with dropping ball into specific region and using gotoAndStop(1)

Question

I am trying to drop "the ball" into a specific region. When the ball is in the specific region, I want the page immediately go to frame 1 using the command "gotoAndStop(1)". However, it is not working. Can someone please help me troubleshoot this issue? Thank you.

this.stop();

var root = this;
this.ball.addEventListener("pressmove", moveBall);

function moveBall(e) {
    e.currentTarget.x= e.stageX;
    e.currentTarget.y= e.stageY;
    root.ball.alpha=0.5;
}

this.ball.addEventListener("pressup", dropBall);

function dropBall() {
    root.ball.alpha = 1;
    if (root.ball.x > 326.5 && root.ball.x < 543.5 && root.ball.y > 211.95 && root.ball.y < 376.7) {
        root.ball.gotoAndStop(1);
        root.ball.alpha = 0.2;
    } 
	else {root.ball.gotoAndStop(0);}
}

When the ball is in the specific region, "root.ball.alpha = 0.2;" is work, but the page not go to frame 1.

Hi.

I would like to suggest another approach for your code that takes into account the scale of the stage, the point where the instance was touched for the drag, besides being more oriented to object and dynamic, I think.

var root = this;
var ball = root.ball;

function main()
{
	createjs.Touch.enable(stage);
	stage.mouseMoveOutside = true;
	
	root.stop();
	
	ball.dragAlpha = 0.5;
	ball.hitAlpha = 0.2;
	ball.missAlpha = 1;
	ball.hitFrame = 1;
	ball.missFrame = 0;
	ball.dropArea = { top: 211.95, right: 543.5, bottom: 376.7, left: 326.5 };
	ball.on("mousedown", onMouseDown);
}

function onMouseDown(e)
{
	var target = e.currentTarget;
	
	target.offset = { x: stage.mouseX / stage.scaleX - target.x, y: stage.mouseY / stage.scaleY - target.y };
	target.alpha = target.dragAlpha;
	target.pressMoveListener = ball.on("pressmove", onPressMove);
	target.pressUpListener = ball.on("pressup", onPressUp);
}

function onPressMove(e)
{
	var target = e.currentTarget;
	
	target.x = stage.mouseX / stage.scaleX - target.offset.x;
	target.y = stage.mouseY / stage.scaleY - target.offset.y;
}

function onPressUp(e)
{
	var target = e.currentTarget;
	var dropArea = target.dropArea;
	
    if (target.x > dropArea.left && target.x < dropArea.right && target.y > dropArea.top && target.y < dropArea.bottom)
	{
        root.gotoAndStop(ball.hitFrame);
        target.alpha = target.hitAlpha;
    }
	else
	{
		target.alpha = target.missAlpha;
		root.gotoAndStop(ball.missFrame);
	}

	target.off("pressmove", target.pressMoveListener);
	target.off("pressup", target.pressUpListener);
}

if (!root.frame0Started)
{
	main();
	root.frame0Started = true;
}

Please let us know if you have further questions.

Regards,

it's not clear which timeline you want to direct to frame 1, but you're directing root.ball to frame 1, not the main timeline and i infer that's not what you want.
