Alright, it should be pretty simple to add, you will need a bit of variables though but its nothing too complicated.
Here's the trigger's that you will need. You only need two triggers to work this, one that adds the check for the upgrade to work and one to add the ability to the units.
Code: Select all
Untitled Trigger 001 Copy
Events
Unit - A unit Finishes research
Conditions
Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
(Researched tech-type) Equal to Iron Forged Swords
Then - Actions
Set IronSwords[(Player number of (Owner of (Researching unit)))] = True
Else - Actions
This first one should be easy to understand, basically it triggers when a building finishes the upgrade, determines what upgrade was done, and then checks the player so the next trigger can add the skill for just that players units.
In the line "Set IronSwords" IronSwords is a Boolean variable, with an array size set as 1-12. You will have to create variables for each of your upgrades.
After "Else - Actions" Repeat the If/Then/Else action just as shown but do it for a different upgrade.
Code: Select all
Untitled Trigger 002
Events
Time - Every 2.00 seconds of game time
Conditions
Actions
For each (Integer A) from 1 to 10, do (Actions)
Loop - Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
IronSwords[(Integer A)] Equal to True
Then - Actions
Unit Group - Pick every unit in (Units owned by (Player((Integer A))) of type Footman) and do (Unit - Add Aerial Shackles to (Picked unit))
Else - Actions
Do Nothing
This trigger checks every 2 seconds to see if the player has finished the upgrade from the previous trigger, and adds an ability that you want to any unit type owned only by that player.
It should be very easy to make, the only thing really confusing could be the line (Units owned by (Player((Integer A))). To get that you need to select "Units owned by player of type" under the unit group option. Then for where you choose the player, the option is called "Conversion - Convert player index to player"
Unlike the previous trigger, for this one you can't put everything under "Else - Actions". Simply copy and paste the actions and change the rest of the parts for the other abilities.

I tested this small system out with two players and it did not conflict, so you shouldn't have many problems with it. If i made something confusing or you cant figure a line out feel free to ask.
