Flip a layer randomly
Hello everyone this is my first post here and I am all new to expressions.
This is what I want to do:
Flip my layer randomly on every new frame to these values only (normal-without flipping, horizontally, vertically, horizontally+vertically).I have searched for hours to find this (it seems it does not have to be so complicated?) but no luck.
Hope to get some help from the pros.Thanks in advance!

Try this scale expression:
n = Math.floor(random(4));
if (n ==0)
value
else if (n == 1)
[-value[0],value[1]]
else if (n == 2)
[value[0],-value[1]]
else

Hello Dan it works perfectly!
I do not understand how the math behind it works though.
What is making the values scale -100% or 100%? Because I was hoping to use this for other things too, for example
making the layer rotate only 0, 90 or 180 degrees.Really appreciate your good and quick response thank you so much!

value returns the current value of the property (as an array for 2D or 3D properties). So for a layer with scale at 100% value would be [100,100]. Flipping just x would be [-value[0],value[1]] ([-100,100]) Flipping x and y would be -value ([-100,-100]). etc.

Your 0, 90, 180 rotation example would look like this:
n = Math.floor(random(3));
if (n ==0)
value
else if (n == 1)
value + 90
else
value + 180Dan

Wow that cleared it all up!
Thanks again!
