Uhm! it’s a dog bit his own tail!
Whit this (imho) too expensive routine (it’s repeated 40 times linked by the cast failed pins):
At actor begin overlap event actor touch volume if is casted remove index and insert the actor at index like the variable value, if not casted go to the next cast check…40 times

-----Any hint to have a routine lighter than that? Now only 20% of the routine give me useful informations, 80% is garbage.-----
how can i obtains the same vars of the actors spawned (20%) in to the volume keeping out of the routine others actors (80%)?
It can solve the next question in one shot, but for knowledge i add:
It stores into the array all actors spawned in the correct index like variable index rank and leave “none” other indexes (array have 40 indexes)…:

the rank is correct but!
I’m going crazy to remove only “none” indexes from the array, i search, i seen, i read a lot of stuff nothing help me.
Thanks in advance.
