Change food via trigger

[Aiun]

I might be blind but I cant seem to find action to change food cost of a unit.
Long story short I have a map where peon spawns every several seconds, then when a production building starts training a unit, a random peon comes close to it. After training is finished, said peon disappears. Instead of farms, abovementioned peons provide food, so I would like created unit to have 0 food cost while it had normal one before.

If you can suggest an alternative way to make it so you can only train units if you have an appropriate number of peons and those peons "transform" into trained units that would also be appreciated.

do you want 1 peon to turn into 1 unit, or when you make a knight suddenly 5 peons (assuming a knight is 5 food) dissappear ?

Pretty much the 2nd option
I have tier 1 organic units with 1 unit for 1 peon
and tier 2 mechanical units with 1 unit for 2-4 peons
(except mortar team that requires 2 units)

I think you'll need 2 versions of each unit-type, one with food cost and one without. Then replace newly created units with their food-free versions.

that will work, tyvm

I'm retarded.
After 2 days of thinking I realized I can make trained units cost as much food as they produce and this fixes everything.

Cool solution actually, i should remember this.

Idk if I really understood the nature of your request @Aiun, in any case, you can use:

• Unit - Disable supply usage for (Triggering unit).

or whatever unit you may need. This will disable the food cost for that specific unit. Not guaranteed to work with transformations...
