Hi everybody,

 

for a personal project I would like to build an oblique progress bar.

 

So, my first question is: Is there a way to create dynamically and easily a Line object with Tweenmax.js?

 

For the moment I just resize the width of a rectangle shape like this : http://jsfiddle.net/FracArt/6GJ67/2/

Which actually works! But seems a bit "hacky".

 

Second question, as you can notice on the jsfiddle file I tried to build an oblique progress bar on the same principle. However, when I rotate the rectangle a gap appears between the initial and final position of the bar.

So do you have an idea of how I can correct that without doing some geometry calculations?

(maybe a transform-origin property on the css?)

Hi and welcome to the forums,

 

One way would be to rotate the element and scale it down with a TweenMax.set and then scale it back to 1, like this:

var obliqBar = document.getElementById("progBar"),
    tl1 = new TimelineMax();

TweenMax.set(obliqBar, {rotation:25, scaleX:.001, transformOrigin:'0% 50%'});

tl1.to(obliqBar, 0.5, {scaleX:1});

I've updated your fiddle so you can see it working:

Hope this helps,

Cheers,

Rodrigo.

Hi Carl, first of all thank you for this great javascript library  :)

 

In the past I used the flash version of this tool and its method LineTo(). However, in view of your last comment, I now understand why I can't find an equivalence with the JS version.

 

 

Problem solved.
