Draggable locked in diagonal movement only

Hello,

 

I was wondering how could I limit a draggable movement only diagonally towards top-left and bottom-right.

 

Thanks guys!

Hi Michael,
 
Not sure how practical that will be to implement. You could rotate the bounds by 45 and then rotate the draggable's target by -45 like this:

Does that work?

Hey Carl I see what you mean, the codepen example doesn't work though, it throws the Codepen 404 equivalent.

Thank you, yes that is what I was looking for, sometimes we have to think out of the box right?

This is in another way to do it:

 

Hi Cirox,
 
You can constrain the shape by doing a little math...

var offset = this.x * Math.tan(45 * Math.PI / 180);
TweenLite.set(drag, { width: this.x, height: offset });
TweenLite.set(handle, { top: offset });

But an even easier approach would be to do it as a ratio. 45 degrees would be 1:1, so just set the height and width equal to each other.
TweenLite.set(drag, { width: this.x, height: this.x });
TweenLite.set(handle, { top: this.x });
