How to make a random number divisible by 4?

Simply use the modulus operator and to make it do it again until the number is divisible just use a repeat loop. Example:
local ranNum
repeat
ranNum = math.random(1, 100)
until ranNum % 4 == 0 -- modulus returns the remainder so if the remainder is 0 you know that the number is divisible by four
I hope this helps and have a great day scripting!
Hello, waffle792!
You can get % to get the modulus, and then test if it is equals to 0
print(6 % 4 == 0) -- This will print false
print(400 % 4 == 0) -- This will print true
After testing, if the number is not divisible by 4, just run the random part again, I would make it a function if I am you
Good Luck with your games
A number is divisible by 4 if it's in the form 4k where k is any integer.
Don't "keep generating random numbers" that's stupid, just generate a random integer and multiply it by 4.

This repeat loop could theoretically go on forever, but the odds are very low for that to happen.
