One upgrade locks out another

[RyanAvx]

Hi!

In my map I'm trying to make an upgrade choice where one is locked out after the other is researched, I've been trying this using a system based on Troll Berserk where the building is upgraded to a different building but it's not going so well.

How can I make a unique upgrade?

Via triggers try detecting the upgrade, and then replace the building with a one that has the wanted upgrade. Though I dont' think I understood you right since you mentioned "researched" so this might not be what you are looking for.

You can disable the "unselected" technology via triggers, making it unresearchable.

Triggers should go like this (broadly):

Event -A unit finishes(or starts to prevent abuse on more than one building) researching an upgrade

Condition- Researched finished equal to "Upgrade 1"
Triggering unit belongs to Player 1

Action - Make "Upgrade 2" unavailable for Player 1


Afterwards copy the trigger and switch Upgrade 1 with 2.
