Global variables
Hi, I’m just a beginner for AE scripting. and now I have this problem.
To move a camera; CAM1, on my composition: COMP1 I use a math. formula, in this formula I have a variable: MxTime= 3;(after 3 seconds do this ….) it works fine.
The problem is, in the same project I have an other composition: COMP2 in which I need the know the value of var MxTime of COMP1.
I’m not able to this, any idea?Thanks a lot

Create an expression control slider, give that the value 3 and reference to that slider from any expression that needs the value.
This will also work if you add an expression (or keyframes) to the slider, every ‘linking’ expression will see the calculated value.
That’s the only crude workaround to simulate globals.
That’s to say: read-only globals:You cannot set the value of that slider from any other expression, only directly from the slider or it’s own expression.
I hope that helps.
