@Gloria Number 1

my actor is already a blue print do i just have an integer variable that is defaul 0 and it will work? how do i give it a number? do i have to make 10000 bp?

If you have a small number of BPs, you can make the integer visible and set it in the level. If you have a large number of BPs, you need to make another actor that gets them all and gives them a number
