change the barrage and the towers attack units allowed to what u just said... maybe u didnt change both? i never used barrage in a game so im not sure about this one
The barrage ability is what can solve this problem. I have used it several times.
-First barrage has a dmg data. This data doesn't do anything. -The AOE of the barrage is the area where it will work. If you set it to 0 it won't work at all. If you set it to more than the unit's range, it will shoot extra arrows at enemy units outside the range. -Max targets DOESN'T WORK. I tried it several times, it did nothing. Just ignore this data. -The max damage really works, just set the max dmg to 3x or 5x to the unit's dmg and it will fire that much rounds. -The targets of the Barrage must be set EXACTLY to the same as the attacks. Blizzard has a bug with Steam Tank: They set the Barrage targets to air, ground and structures, and if you research the barrage the tank will instantly spawn a rocket to the building when it attacks that instead of the normal tank round explosion. -Cooldown: i have no idea why it has a cooldown. Set to the cooldown of the unit and you won't have any problems -Duration: leave this data on 1. -Missile Art: change it to the missile art of the unit.
