Wiggle expression between 2 values only
I hope I’m not reposting, I just can’t find the answer anywhere. Basically I want to switch a layer on and off randomly.
In order to do this I’ve added a wiggle expression to the opacity. This works but I need it only to use the values 0 and 100. Is there a way to have it only use these values or do I need to approach this issue differently?
Thank you.

You’ll want the result from your wiggle to be a variable and then use that variable in an if then statement.

Just set the value to 50 and add an expression like this:
wiggle(1,50) < 50 ? 0 : 100

I got it to work. Thanks a million for your help. Much appreciated.

Can you explain the syntax of this expression ? Cause I’ve seen numbers inside the parenthesis of wiggle expression. Not outside.

It basically says if the wiggled value is less than 50, set the result to 0, otherwise set it to 100.
ThE ?/: syntax is an example of the JavaScript ternary operator, which is a compact form of if/else.
