Berserker Upgrade problem

[BebopJelli]

I want to make the berserker upgrade effect another unit in addition to the spearthrower. However, the baracks will not hide the new berserker unit portrait.

I have the Troll Spearthrower and the Forest Troll in the baracks, each with a berserker version. The Spearthrower is fine, but the Forest Troll and Forest Troll berserker show up in the build menu of the baracks untill the berserker upgrade finishes, at wich time only the berserker versions are there and everything is fine.

Any ideas why this happens and how to fix it?
NOTE: I have found one way, to make a seperate berserker upgrade that basically does the opposite of the real berserker upgrade. This doesn't seem to be the way blizzard did it though, anyone able to help?

I believe you need to dissable the availablibity of your berseerker unit at map initialization.

[Edit]: The reason being that the ability changes the availablity of the units, so the old one is now unavailable, and the new one is available.

Event:
- Map init
Conditions:
Actions:
Pick every player in (All players) and do
- Player - Make <new unit> unavailable for training / contruction by (Picked player)

The upgrade takes care of bringing it back and hiding the original.


Yes, in melee maps it's automatic.
Well, a simple trigger...

I was hoping i missed a gameplay constant or something. Oh well, thanks for the help.

Edit: I would just like to note to anyone reading, I have found that using berserker upgrade twice to effect the same units causes many un-expected problems such as not changing the desired units or effecting availability at all. In order to do what I have asked in the op, triggers must be used.
