Problem of delay on TweenMax

Recommended Posts

Hi,

 

I'm not an expert in GSAP and I have some troubles with my SVG animation. 

Indeed,  I want to create a pre-loading effect on my page but I have some issues regarding the delay. I made a screenshot which show my problem : https://vimeo.com/189758547

My SVG appears at the beginning of my animation but I want to reveal the SVG by animating the strokes.

 

Here is my JS code (the link to my https://codepen.io/MaralS/pen/jMgmQY) :

$(window).load(function () { 
        $(function () {
            var first = $('#firstletter'),
                second = $('#secondletter'),
                competences = $('.competence'),

                // Sample script for Tweening on a Timeline
                tl = new TimelineMax({
                    delay:0,
                    paused: false,
                    yoyo: false
                });

            tl.fromTo([first, second], 3, {
                drawSVG: "100% 100%"
            }, {
                drawSVG: "0% 100% ",
                ease: SlowMo.easeOut
            });
        
            tl.fromTo(competences, 1, {
                opacity: 0,
                top: 0
            }, {
                opacity: 1,
                top: "50%"
            });
        });
        $('#loader-overlay').delay(5000).fadeOut('slow'); // 5 sec de délai avant que la div ne disparaisse
        
});

 

Thank you for your help :)

I'm no expert at this at all but could you tween css properties for the loader container from display none to display block like so:

Hello MaralS, and Welcome to the GreenSock forum!

 

if it was me i would use the GSAP CSSPlugin special property autoAlpha

 

See the Pen RGXQXR by jonathan (@jonathan) on CodePen

 

So instead of using display:none on #titre-conteneur in your CSS, which will remove your element from the rendering tree when loaded. You would use visibility:hidden; to hide the element on load.

 

Then you would animate autoAlpha to 1 with a to() tween:

tl.to(loader, 1, { autoAlpha: 1 });

autoAlpha is part of the GSAP CSSPlugin:

 

http://greensock.com/docs/#/HTML5/GSAP/Plugins/CSSPlugin/

 

autoAlpha is better for rendering performance ;)

  • autoAlpha
    Identical to opacity except that when the value hits 0 the visibility property will be set to "hidden" in order to improve browser rendering performance and prevent clicks/interactivity on the target. When the value is anything other than 0, visibility will be set to "inherit". It is not set to "visible" in order to honor inheritance (imagine the parent element is hidden - setting the child to visible explicitly would cause it to appear when that's probably not what was intended). And for convenience, if the element's visibility is initially set to "hidden" and opacity is 1, it will assume opacity should also start at 0. This makes it simple to start things out on your page as invisible (set your css visibility:hidden) and then fade them in whenever you want.
//fade out and set visibility:hidden
TweenLite.to(element, 2, {autoAlpha:0});

//in 2 seconds, fade back in with visibility:visible
TweenLite.to(element, 2, {autoAlpha:1, delay:2});

Happy Tweening! :)
