I need to know how to make a player group then have vision be shared for all players any help would be nice.
I tried having all players put into an empty player group but i don't know if that's what i was suppose to do.

If they are all allies, then just look under the trigger category "Players" and find "Player - Make all players in Player Group treat each other as Ally/Enemy/Neutral With Shared Vision" (Or just search for it). This method must specify an allied/enemy/neutral relationship though.

Otherwise, you will have to do something along the lines of



There's probably a more effective way than that, as this will take a second to run (and really should only be done once. The first method seems the most viable.

Easiest way is this:
there is a action called like "Set alliance for all players in player group" (or something similar, search in the category Player Group, you'll find it).

But again, you can't ignore the enemy/allied/neutral flag, as it must be set through this trigger. If they are all allies or all enemies or all neutral, this trigger will work fine. However, if you only want mess with shared vision, and not the allied/enemy/neutral flag, then you'd have to use something like the second method i posted.

Yeah this works, I've done it myself.
