Dragging, Tracking and User Input

Flash MX: Dragging, Tracking and Input
I have a draggable MC (called square1) with some code attached to an onClipEvent(mouseUp) handler that tracks the x and y positions of the MC when it is dragged to a new position.

These will later be passed to a sharedObject in order to save these positions for later reuse.

This all works OK, but I need to also allow the user to enter 2 values for x and y (into 2 boxes named xPosition and yPosition) and then have the MC move accordingly. Here is the current code:

onClipEvent (load) {
this._x = _root.xPosition;
this._y = _root.yPosition;
}

onClipEvent (mouseUp) {
xPosition = Math.round (_root.square1._x);
yPosition = Math.round (_root.square1._y);
}

Changing the values in the input boxes does not move the MC and if I change the onClipEvent(load) to (enterFrame) then the dragging functionality fails to work.

What am I doing wrong?

Values inputed in input textfields are strings and not integers. You have to convert them into integers with int. Also may be a good idea to limit the inputed characters as numerals. Hit the Character tab and select Only... 0-9.

this works fine

square1.onMouseDown = function(){
startdrag(this);
}
square1.onMouseUp = function(){
xPosition.text = Math.round (this._x);
yPosition.text = Math.round (this._y);
stopdrag();
}
square1.onEnterFrame = function(){
this._x = number(xposition.text);
this._y = number(yposition.text);

}

oops i was premature

only allows 1 drag

 

[billwatson]

fixed it

square1.onPress = function(){
startdrag(this);
}

square1.onMouseUp = function(){
stopdrag();
xPosition.text = Math.round (square1._x);
yPosition.text = Math.round (square1._y);
}

xposition.onKillFocus = function(){
square1._x = number(this.text);
};
yposition.onKillFocus = function(){
square1._y = number(this.text);
};

Hi Bill,

Thanks so much for the reply - the code sample you've given works beautifully.

Next job - get the loop functions working right as there will be over 100 of these MCs, all generated and named dynamically.

Good job I've got the aspirin handy.
