Something regading upgrades

[Reinhold]

In one of the maps, I saw a research that allows a unit to be trained with less food, thans to a research. (ex: Frost Wyrm - 7 food; research complete => Frost Wyrm - 5 food)
Can anyone help me with this?

You may use triggers to do this. You will need an exact copy of your unit (say, a Frost Wyrm), which uses a different amount of food, and you will also need an upgrade which does nothing (let's call it "Food Upgrade").
Then use triggers to replace Frost Wyrm [7 food] with Frost Wyrms [5 food]. This must apply for units already present in the map and units that have not been trained yet.
Something in that area:

• Food upgrade trigger
  • Events
    • Unit - A unit Finishes research
  • Conditions
    • (Researched tech-type) Equal to Food Upgrade
  • Actions
    • Joueur - Make Frost Wyrm [5 food] Available for training/construction by (Owner of (Researching unit))
    • Joueur - Make Frost Wyrm [7 food] Unavailable for training/construction by (Owner of (Researching unit))
    • Set GroupVar = Pick every unit in (Units of type Frost Wyrm)
    • Unit Group - GroupVar and do and do (Unit - Replace (Picked unit) with a Frost Wyrm des glaces using Difference with the old unit relative life and mana)
    • Custom script: call DestroyGroup(udg_GroupVar)

I didn't test it out, but I suppose it should do the trick.

I'll try.
However: GroupVar = Pick every unit in (Units of type Frost Wyrm)
I don't know how to set GroupVar as.

you need to create a Unitgroup variable first. To edit/create variables click on the yellow "X" in the trigger editor

then use the set variable action, which is within the first 10 actions in the list. you can also access the variable menu from there.

i suggest you look up a tutorial on variables as well

You can actually just use custom Berserker Upgrade to do this. You need no triggers just only a custom techtree.

I actually tried that, too, but the only option useful was "Units of type Frost Wyrm" and that's it, without "Pick every unit in". Also, is there a version difference? Because in my version there's no Unit Group that accepts a variable for the GroupVar variable.
@Love Seeker: I'll try that, too.

"Units of type" is correct. It's a typo because Sieben translated his from French WE to English. The "pick every unit" syntax is for unit group actions where you don't put in into a variable.

 

[Reinhold]

I did try your version, Love Seeker and when I select the Boneyard, instead of 1 Frost Wyrm as it should be, there are 2. Talk about confusing.

 

[GaLaxY_256]

You did not unticked the upgraded frost wyrm in techtree, do you? It is in Scenario->Techtree Properties, tick Use Custom Techtrees, Select All Players and then uncheck your upgraded wyrm.

Thank you! Now it works!
