Not sure what that trigger is trying to do exactly.
1) ResourceInt[100] seems random, what does this represent? The Index -> [the number in these brackets] is NOT the value of the Variable if that's what you're thinking. I recommend looking up how to use Arrays.
2) It looks like you never reduce ResourceInt[100], it'll keep it's original value even after a Soldier enters the map.
3) You display a reduced ResourceInt[100] in the Multiboard, but that doesn't actually reduce the Variable itself. You're just telling the game to display "X-20" in the Multiboard. If X never changes, than it will always display the same thing.
Anyway, what were you having trouble with?
I put a README file in the Trigger Editor of my map, if you click it you'll see step by step instructions on EVERYTHING that you need to do to get the system to work.
Object Editor instructions:
1) Find your Structure that Trains Units in the Object Editor (A Barracks for example).
2) Go through each of that structure's Trained Units in the Object Editor and set their Art - Button Positions to X: 0, Y: -11. You need to SHIFT-click the field in order to type in negative values.
3) Go to the Ability Editor and create a new ability for each Trained Unit. I recommend basing them off of the Abilities I already made. Then Add these new abilities to the Barracks.
4) Make sure these Abilities follow my instructions. They need a different Base Order Id from one another and you need to put the Trained Unit's Rawcode in the Tooltip - Turn Off. So if the Ability is meant to Train Footman, you put "hfoo" (without the quotation marks) in the Tooltip - Turn Off. Again, you can just follow the examples I already made.
5) You may also want to remove or keep the Gold/Lumber/Food costs from your Trained units depending on how your map works.
That should be everything you need to do in the Object Editor.
After that you go to the Trigger Editor in order to add your Structure to the system:
1) Following my Setup trigger, you set TM_UnitType[0] = Your Structure that trains units:
-
Set VariableSet TM_UnitType[0] = Barracks
2) You set TM_Trained_Total = How many units the Structure trains, in my example my Barracks trains a Footman, Rifleman, and Knight, so 3 units in total:
-
Set VariableSet TM_Trained_Total = 3
3) You then set TM_UnitType[1] to TM_UnitType[X] to be equal to your Trained Units. The first Trained Unit always starts at Index [1] and then you increase this by 1 for each new Unit.
-
Set VariableSet TM_UnitType[1] = Footman
-
Set VariableSet TM_UnitType[2] = Rifleman
-
Set VariableSet TM_UnitType[3] = Knight
4) You do the same thing as Step 3 but for the Abilities. Make sure the Units/Abilities Indexes match. See how TM_UnitType[1] is Footman and TM_Ability[1] is the Train Footman ability, they go together therefore they need to have the same Index [#].
-
Set VariableSet TM_Ability[1] = Train Footman (Ability)
-
Set VariableSet TM_Ability[2] = Train Rifleman (Ability)
-
Set VariableSet TM_Ability[3] = Train Knight (Ability)
5) Lastly you Run a trigger that my system uses in order to Add all of these variables to a Hashtable. There's nothing special you need to do here, just make sure this Action happens after you're done setting all of the Setup Variables for your Structure.
-
Trigger - Run TM Add To System <gen> (ignoring conditions)
When you want to add another Structure to the system you would follow these same exact instructions. So you would Copy & Paste all of the Actions above, and then adjust their values to use your new Structure/Units/Abilities.
