doesn't work on a mobile screen

Thank you. Please tell me, is there a link to the documentation that describes all the commands when working with canvas on a touch screen?

I'm sorry. Attached  -  fla and example code. 

I repeat. Everything works fine on a desktop with mouse controls, but does not work on a mobile device with a touch screen. Can you tell me what to do?

var root = this;
this.yes.visible=false;
this.ball.on("pressmove", moveBall );

function moveBall(e) {
		var p = stage.globalToLocal(e.stageX, e.stageY)
		e.currentTarget.x= p.x;
		e.currentTarget.y= p.y;
	
}

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

var myN=0;

function dropBall () {
	
	if(root.ball.x>85 && root.ball.x < 1180 && root.ball.y > 65 && root.ball.y < 365 ) {
		root.ball.alpha=0.5;
		root.ball.x=root.myRect.x;
		root.ball.y=root.myRect.y;
		root.yes.visible=true;
		myN++
		if(myN>5) {
			root.ball.visible=false;
		}
	} else {
		root.ball.alpha=1;
		root.yes.visible=false;
	}
		
	
}
