Hi all,

I'm trying to nest a timeline within another but it doesn't seem to work.


Here's my demo:


The first timeline, red1, alternates between two states, in this example different x positions. I also want this red1 timeline to move like the blue box.

Is this the proper way to go about it? Or is there a better way?

I'm new to this and not very fluent with GSAP, or scripting for that matter.


Thanks in advance!

Hi mattVo :)


Welcome to the forums.


This can work for you with a couple of small changes.


1. You have the x position of the red box wiggling back and forth by 3 pixels which is fine, but then you're asking it to move 500 pixels on the x on the other timeline. This causes a fight for control. The simple solution here is to wrap the red box inside a container and then move the container along the x by 500px.


2. On your master timeline, you were trying to move the red1 variable by 500px, but red1 is a timeline not the red box itself. 


I've forked your pen and made those changes:

Hopefully that gets you closer to what you wanted.


Happy tweening and welcome aboard.
