So, I'm working on a character that someone else has made, doing a few edits and tweaks to make it play a little better. One of this character's moves means that the other player has to struggle to get free. Every time they struggle, the struggle counter goes up by 1. Previously, when the struggle counter reaches 8, the player would be released. I thought this was a bit streamlined and wanted to be able to randomise the amount of struggles someone had to do before they could escape. My main issue is that most of what I have found on here tells you how to assign a variable a random number, but I want the number of struggles needed to escape to be random, rather than the number of struggles, if that makes any sense.

The main part of the code that I'm focussing on is this:
[state 1004] ;release
type = changestate
triggerall = numtarget
triggerall = target, alive
trigger1 = var(4) = 8 && (var(5) = 1)
trigger2 = roundstate = 3
value = 1012

Var(4) is the variable dealing with the number of struggles. Therefore, "trigger1 = var(4) = 8" is saying "when the amount of struggles reaches 8, they will be released". The 8 is therefore the integer that I want to be randomised but, pretty much all my methods have been unsuccessful. I have managed to find out how to generally make the integer random, simply by doing this: "trigger1 = var(4) = random". This provided me with a random number of struggles needed to escape, but I would really like to define the range of numbers that can be picked, 1-16. I have tried lots of different things and either the game will be unable to load the character or the other player is released instantly without struggling. If anyone has any idea how I can set it so that var(4) = a random integer between 1-16 that would be fantastic!

Also, I should probably mention that I am not great at coding :(. Though, I'm definitely better than someone who's never coded in their life
