How to make a unit gain "experience" and level up?

[DDDX]

Hi guys.
Need some advice.
For the purpose of making a RPG - style unit, is it possible to code a detection in mass value killed, so that when you have killed let's say 1 million worth of mass with that unit, the map script would then remove the unit in question and replace it with a bigger, better, stronger version of itself?

The part I am having trouble with is the detecting of mass killed. Now, i remember once reading of a mod that plays around with unit stats based on that unit's veterancy, by making it have a shield on higher vet levels or even becoming a different unit altogether when it vets, but I cannot remember what that mod was. If it exists, it would be a good workaround for me if the mass killed thing is not possible to code.

Any ideas? Thanx in advance.

You have a deep veterancy system on Alliance of Heroes mod.

The best way to do what to want is to hook the onKilled function in unit.lua

Code: Select all

   OldOnKilledUnit = Unit.OnKilledUnit,
   OnKilledUnit = function(self, unitKilled, massKilled)
      if not massKilled or massKilled == 0 then return end -- Make sure engine calls aren't passed with massKilled == 0
      if IsAlly(self:GetArmy(), unitKilled:GetArmy()) then return end -- No XP for friendly fire...
      self.MassKilled = self.MassKilled + massKilled -- Saving Mass Killed by unit
      -- Your stuff : unit creation or buffing
      ---------------------------------------
      Unit.OldOnKilledUnit(self, unitKilled, massKilled)
    end,

About the replacing system, do you want to keep the current unit graphic model ?

if yes, you can just apply a buff on your unit (that can boost, health, max health, damage, speed, rate of fire, regen...)
If no, you need a new model, you need to kill your unit (without explosion) and create a new graphic model :
for example

Code: Select all

local pos = uniKilled:GetPosition()
local unit = aiBrain:CreateUnitNearSpot('URL0107', pos[1], pos[3])


I'm not sure about pos[3], it's maybe pos[2], cause you have x, y, z position. You need to add some conditions depending of mass killed and unit models...

Ask if you need more information

Modifying the unit.lua will loop over every unit and count every masskill.
If you only want a single unit to count then modify only the unitscript like this:

Hooking 'OnKilledUnit' from unitscript:

Code: Select all

local TConstructionUnit = import('/lua/terranunits.lua').TConstructionUnit
local MassKilled = 0

DUMMY0815 = Class(TConstructionUnit) {
    OnKilledUnit = function(self, unitKilled, massKilled)
        -- add the mass of this kill to our mass counter
        MassKilled = MassKilled + massKilled
        -- if we killed over 1,000,000 mass then...
        if MassKilled > 1000000 then
            --do stuff here like creating new unit etc.
        end
        -- call the original function, so we don't break it.
        TConstructionUnit.OnKilledUnit(self, unitKilled, massKilled)
    end,
}
TypeClass = DUMMY0815

awesome. Thank you!!
I was hoping something like that would be possible.
I can remove wrecks, figure out positions, disable detah animations etc, that's not the problem. What I don't know i figure out through trial and error. This last piece of code, for specific units is exactly what I needed. i shall also look into the Alliance of heroes mod for more info.
Thanx again, man!
