• Decrpy PROPER 2 Copy 8
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • ((Ability being cast) Equal to Decrypt ) and (Decrypt12 Equal to 0)
  • Actions
    • Set SpawnLoc = (Target point of ability being cast)
    • Unit - Create 1 Decrypter for Player 12 (Brown) at SpawnLoc facing Default building facing degrees
    • Custom script: call RemoveLocation (udg_SpawnLoc)
    • Set DecryptRed12 = (Last created unit)
    • Set Decrypt12 = (Decrypt12 + 1)
    • Set SpawnLoc = (Position of DecryptRed12)
    • Visibility - Create an initially Enabled visibility modifier for Player 12 (Brown) emitting Visibility from SpawnLoc to a radius of 1024.00

    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (DecryptRed12 is alive) Equal to True
      • Then - Actions
        • Set Player = Player 12 (Brown)
        • Custom script: if GetLocalPlayer() == udg_Player then
        • Sound - Play RADAR_On <gen>
        • Custom script: endif
      • Else - Actions

I gave each player a similar trigger but it spawns a unit for every living player.

What did I do wrong?

This is the problem:

I gave each player a similar trigger

Just change all "Player 12" in your trigger to "Owning Player of Triggering Unit" and remove all other instances of this trigger. You just need one trigger for this.
Also, make "DecryptRed12" and "Decrypt12" array variables and index them by the player number:
Decrypt[Player ID: Owning Player of Triggering Unit]
