Active ‘if statement’ over a number of frames
If I want to generate a random number in an expression and have an animated blink happen if a certain number is chosen, how could I have the blink last for more than one frame? Like an ‘if statement’ on the opacity of a layer allowing the opacity to be at 100% over 3 frames if the number 5 is randomly generated.
There may well be a better way to do this but I wanted to know for my general knowledge if it’s possible to have something trigger from a random number in an expression (as an example) and be ‘on’ for more than one frame from that trigger.

The most straightforward way is probably to start your expression with
posterizeTime(10); // evaluates at 10fps
Then the rest of your code

Thank you. I see my problem was that I had the random statement in the same expression as the opacity ‘if statement’. I have put the random statement with the posterizeTime statement in an expression on an adjustment layer with a slider now and it works the way I need it to. Thanks again.
