Question regarding your horizontal scrolling example

[KwabenaOwusu]

Hi Team,

I am a GSAP newbie , Club Green Sock member , I bought a  snorklTV  creativecoding membership.

Short: I am trying my best to learn as much as I can.

 

Question: In the above example the container width is 600% but for the scrolltrigger you set  -> end: "+=3500".

 

Could let me know why 3500 px from the starting point (trigger element)?

 

Thank you.

Hi Kwabena,

 

Glad to hear you are enrolled in my courses.

Studying these demos is a great way to increase your learning!

 

I'm guessing in this case that the developer just chose 3500 as a number that is "big enough" to work well in most cases.

 

I just made a fork that uses a "function-based value" which figures out the scrollDistance based on the width of the window * number of sections.

 

See the Pen LYMEdZb?editors=0011 by snorkltv (@snorkltv) on CodePen

 

 

This will allow the vertical scroll distance to be the same amount that things are moving horizontally.

An added bonus of function-based values when used with ScrollTrigger is that they automatically get re-calculated on window resize.

 

Be sure to open the demo in a new window and watch the console for updates after you resize.

 

hope this helps

Carl

@Carl: Thanks very much.

Yes, I enrolled in your course three months ago (26th May ). I am currently on the monthly subscription. I think I will switch to the "lifetime" package.

BTW you are the best coding teacher. Your courses are great.

Glad that helped and thanks so much for the kind words.

If you want to switch plans just send me an email and i'll provide some instructions.
