sorry for bad english.
If use mootools and try to change "position" attribute, autoCss function GSAP  detect "position" in target and don't add it to vars.css, becouse mootool add "position" method to Node prototype.

i fix it in my local machine, but...

where can i write, to fix it in future?

Hello OxXxigen, and Welcome to the GreenSock Forum!


Anytime your using GSAP, its best to use GSAP set() method instead of MooTools autoCSS or even jQuery css() method. This way you allow GSAP to set your CSS properties you will be animating. If you use the MooTools or jQuery css methods you will be changing CSS properties on DOM elements outside of GSAP.


In GSAP use the set() method. Link to the GSAP set() method in the Docs:




Example of GSAP set() usage:


Immediately sets properties of the target accordingly - essentially a zero-duration to() tween with a more intuitive name. So the following lines produce identical results:

TweenMax.set(myObject, {x:100, y:50, opacity:0});
TweenMax.to(myObject, 0, {x:100, y:50, opacity:0});
And of course you can use an array to set the properties of multiple targets at the same time, like:
TweenMax.set([obj1, obj2, obj3], {x:100, y:50, opacity:0});

You can also use selector text to target DOM elements that match that criteria.


So basically when using GSAP.. use the set() method, so this way you allow GSAP to keep track of your CSS properties on the elements your animating. Otherwise if you use MooTools or jQuery CSS methods you are changing CSS properties outside of GSAP.

thanks for answer.. 

but problem doesn't in that.....code for example
part of TweenMax.min.js

z = function(t, e) {
    var i, s = {};
    for (i in t) B[i] || i in e && "transform" !== i && "x" !== i && "y" !== i && "width" !== i && "height" !== i && "className" !== i && "border" !== i && "position" !== i || !(!E[i] || E[i] && E[i]._autoCSS) || (s[i] = t[i], delete t[i]);
    t.css = s

as i understood this is function that convert params obj assigned to function, into Obj.css

and when this function check "position" key, look at the "|| i in e &&" part of code..

in this part original lib diside that "position" need to be called becouse of mootools add method position to DOM elements.

i fix it added "&& "position" !== i" part of code to originl lib.


sorry for bad english.

You could simply define your CSS values inside a css:{} object so that it's very clear which ones are CSS-related and which are not. Or set autoCSS:false. I don't think it would be appropriate to add that "position" code to the core. Frankly, this seems like an odd behavior in MooTools.
