Ok found it ty. Now I have new problem because I have 2 player team with 2 computer ship attackers, How i put only first team can reserach this ability and team number 2 can only theyr?
P.S A super extra idea for upgrade, I like if can make a dialog button for upgrade attack and armor of ship when a unit within in range x of unit, good no? but how i set for gold, if player have 100 gold research start, instead don't have don't start?
