Random Generator renew rate?

I have random(99) in my event list 16 or 17 times. Is it true that its generating only once per tick? So i have random(99) same each time, renews only when start doing the list again (in second tick)? Solution?

No, it gets a random number each time you use random, not once per tick.

you could also set up the generator to a time. so evry x milliseconds it generates a creature, and in the time (if your character levels up) you can set time/character ('Level')

so condition- every x miliseconds/global('level') Event-system creates creature on Generatorx, Generator Y
