Flashcard Animation in Storyline

Next step...
first i add a variable for the scale... A number set to 2.5
As it is a Storyline variable i need to add this line to each Javascript trigger to get that value.
var player = GetPlayer( );
To get the variable for the scale i use this code.
var myScale = player.GetVar("scaling");
And then i can change the scale:2 everywhere to scale:myScale

Now you can easily change the scale... 2.5 is a bit too big when you test it.
2.07 perfectly covers all 4 cards. I do have a calculation somewhere to calculation the perfect percentage for things like this, but for now not using that as i dont want to complicate things.

So now the repositoning part...
Quite some solutions for that, but using the simplest one. I add a shape that has the position i want for the final scaled Cards. GSAP has a nice helper function 'getProperty'. With that we can grab the postion of that element, and reposition our card to it.
var xPos = gsap.getProperty(CTRL, "x", "px");
You can get any property from an element... height, width, whatever... if you add a second parameter as here 'px' the property is given back in pixels. If you dont add that, its more versatile. I seldom add that second parameter as i noticed it works better letting GSAP decide what unit to use. So like this...
var xPos = gsap.getProperty(CTRL, "x");

At this point i have to focus on other projects.... will continue this later...

Offcourse its made with GSAP. ;-) And as Storyline now includes the latest version of GSAP its easier then ever to create animations and interactions like that with Storyline. As im in the process of creating a sample/tutorial for another community member on how to work with GSAP in Storyline i will enhance that one with the flipping sample. 

As promised here is the solution for the Modern Player and resizing the browserwindow.

Only the card with the red cadre around it has it implemented. When time permits i will rework the complete flipping card example to work as needed...but resizing the page/window and then flipping the card with the red cadre and you see it stays nice at its position...in contrary to the rest.

I will give a proper description how it works and what code you need from it to get it working on other projects. But for now here is the working sample too.

Rise 360 type Flashcards in Storyline 360

Overview: Enables flashcard animations that can incorporate images, text, or a combination of both, triggered by mouse click or tap, similar to the flashcard animations in Rise 360. Special thanks to Math Notermans from the Articulate E-Learning Heroes Community for his ingenious customized code and examples. Inspired by his work, I adapted one of his scripts to create a dynamic flashcard animation effect and meticulously designed it to emulate the seamless Rise 360 flashcard look and feel. FYI: Math's ingenious JavaScript method utilizes GSAP for animation, while Storyline's Alternative text "Alt Text" (Accessibility) is used to identify objects/groups to be called. In the paraphrased words of LL Cool J, this method "Rocks the Bells."

To address objects jumping to new locations when resizing the window, I applied the following fix/hack: Grouped the front card object/group and the back card object/group into one group (e.g., card 1 group, card 2 group, etc.).

To address over- or under-rotation caused by clicking objects too soon or repeatedly before the animation is completed, I implement the following fix/hack: I added a layer with a dead "hotspot" for each card to pause interaction for the duration of the rotation.

*I attempted to adjust the code for both issues, but this was the simple and most stable solution.

Sorry, Math, if I hacked up your code. Feel free to correct it if needed. So far, this has been stable for me and my clients.

Warning: Check that it is working as intended every time you update SL to the latest build.

Math Noterman has an example of a flip card made in Storyline on his profile page. He does not say how he created it but you can check out his profile here and if you like what you see I’m sure he would be happy to share how he did it.

The old version on my profile page still used jQuery and externally loaded GSAP. As that is not needed anymore i removed that from the Storyline file and reworked it so it only uses Vanilla Javascript.

Basically it works like this...

On start of the timeline all is set to its initial state. With queryselector getting all the needed elements, then hiding whats needed...lastly hiding the blocker. Showing that in this screenshot... blocker moved on purpose so you see the texts...



Then all cards and backcards have Javascript triggers.

Basically all the cards do the same more or less. With gsap.set some values are set directly so you donot see any change on screen. Then with gsap.to the animation is triggered... basically a simple perspective rotation 'rotationY' with some eases. To ensure all is properly visible i exchange the z-order of the different elements. For that i added a changeMan element ( the small block on top ) for each card. Its invisible, but used to control the z-order of the elements. So when the card is turned indeed the backside is showing on top in Storyline.
Do copy the code to a code-editor like Sublime Text with color coding, else you go bananas trying to get this right straight in Storyline. As seen below.



I add the working Storyline as a NewYears present ;-) ..if you need help...shout...
Happy coding in 2021

Yeah...Modern and Classic player behave quite different especial on x transformations. I did write up quite some upon it and do have fixes for it. This one was older, so its not in yet i guess.
Using % instead of pixels might help... vw and vw do work too in GSAP... Basically the y rotation might be different indeed depending on values...

If needed i can update this...

Thanks I have muddled through and refined the animation to what I want (I like things a bit faster). I will have a play with sorting out the movement in the modern player. 

In other posts on the community fixes for this i show as do some other members. I dive into it and fix of.

Finetuned it a bit, so basically there is now a variable called flipDuration. You can change that to influence the duration/speed of the flip. Also got rid of the 'events' needed in the previous one..checking the resizing of the window. Now all in the scripts on the cards.
