looking to even things up but need help doing it

[leonstrider]

was wondering if someone could help me with this i am trying to edit the experience gain to where it gives more experience to weaker units killing stronger ones and less exp to stronger units killing weaker ones

example of what im talking about in mathmatical senses
(base experience multiplied by defeated units level) divided by killing units level equals experience gained rounded down to the nearest whole number

further example
(10*1)/3=3.33=3 experience gained same as in (10*1)/2=5=5 experience gained
or (10*3)/1=30=30 experience gained

hope that clearifies things up a bit but i was wondering first if this is possible in wml or not and second how would i write that for it to work correctly im trying to even things up a bit for campaings where a lvl 10 cant just masacre a field of lvl 1s and keep on going and to where a lvl 1 can advance faster for killing a stronger unit *more or less trying to balance things out*

Well, it's gonna be really complicated to make that work due to all sorts of corner cases you have to deal with, such as if the unit normally would get enough XP from a kill to level up but now won't.

You should start with last breath, die and/or attack end events and first figure out at what point in the sequence the unit's XP is actually incremented and whether you can simply decrement the XP of a unit which would be about to level to cancel the levelup or not.

i would like the syntax to calculate the information its given first then apply it to the "experience meter"

Column on the right: lookup the following tags.

[event]
[store_unit]
[if]
[variable]
[then]
[else]
[unstore_unit]
Also search the wiki for FormulaAI

And as zookeeper said it will take some trial and error for figuring out when to modify things.
You want to store them before they get exp. Then modify the exp on that unit and unstore it AFTER the exp gain in the game.

If the game won't let you store before and unstore after then you'll have to calculate how much exp they got and subtract before you add in your values. This will be a massive pain though...

Well, couldn't he just add negative XP before the unit levels, if he wants less XP that would prevent it from leveling? Or am I just over-simplifying again?

Subtract-beforehand might be problematic because it would sometimes result in (temporary) negative experience numbers. I'm not sure how the game handles these.
