Yes, i have got it.
Well, i dont quite know why that condition aint working, but you could of course just swap it with 2 other conditions.
basically all you need to check is that player 1 (red) is not in TEAM2 and the triggering playr is not in TEAM2 as well.
the condition i gave you was basically those two conditions in one line but if it doesnt work then try to split it into 2.
(Player 1 (Red) is in TEAM2) Equal (Triggering Player is in TEAM2)
which i posted in that thread should do it, because it will only return true if either both players (1 (red) and triggering player) are in TEAM2 (force variable) or both aint. if one of them is in TEAM2 or the other the trigger wont work. if both are in TEAM2 it doesnt matter cause as far as i got it all players in TEAM2 are allied by default.
Is the school system in your country similar to Chinese school system? I could never imagine being a teacher in a Chinese school, what's expected of students and teachers is just so different from what I'd be looking for as a teacher
