Yep i have tried. But still the same issue.
I will try to be more clear.
I have 4 objects, thus 4 knobs(red, blue, green, yellow) that are initially set invisible.
The idea is that each 3 to 6 seconds one of them will become visible for about 3 seconds and then another one will randomly do the same.
But when I write 4 conditions "-pick random button instance - set visible" for each of them they shine all at the same time.
I even tried to put an or between the 4 conditions, same result.
And then there is another issue, i would like to turn them down after maximum 3 seconds of activity. So i've made a sub event and put 2 conditions in it (if button visible, compare time >3 seconds---->set invisible)...now it's all black lol
There must be a thing i don't get, it's very frustrating
