Cromcrom lua stuff and questions about terrain features attrition mod

Mountain should be the highest risk/most damage, because it's not even passable terrain in the base game. Speaking as a citizen of Chicago, ice is dangerous but icy mountains are much, much more dangerous!
 
Code: 
function damageAndDestroyUnit(pPlayer,iUnit,minDam,maxDam)
 local tKillUnits = {}
 local pPlayerToCheck = Players[pPlayer]
 local pUnits = pPlayerToCheck:GetUnits()
 for i, pUnit in pUnits:Members() do
  if(tostring(pUnit:GetID()) == tostring(iUnit)) then
   local unitDamage = math.random(minDam,maxDam)
   if (pUnit:GetDamage() + unitDamage) >= 100 then
    table.insert(tKillUnits, pUnit)
   else
    pUnit:ChangeDamage(unitDamage)
    print("inflicted "..unitDamage.." to unit")
   end
  end
 end
 --now we've completed the iteration through table pUnits:Members() and can safely delete units listed as members
 for k,pUnit in pairs(tKillUnits) do
  pUnits:Destroy(pUnit)
  print("a unit was destroyed because of attrition")
 end   
end
function Attrition(PlayerID,UnitID,UnitX,UnitY)

Events.UnitMoved.Add(Attrition)

This works as intended so far. Inflicts damage on moving units. Terrains mostly increase damage, and give a chance for a catastrophe to happen, that will increase damage even more. I have feedback on the map in case of catastrophe.

I have an issue tho with roads, but it is quite late over here, I will have a better look tomorrow.

I will make the mountains passable (should be easy with SQL and the great tuts here and there), and release the mod, hopefully in a few days. Cheers.
 
Released on Steam.

Here is the lua code:
Code: 
function damageAndDestroyUnit(pPlayer,iUnit,minDam,maxDam)
 local tKillUnits = {}
 local pPlayerToCheck = Players[pPlayer]
 local pUnits = pPlayerToCheck:GetUnits()

  if(tostring(pUnit:GetID()) == tostring(iUnit)) then
   local unitDamage = math.random(minDam,maxDam)
   if (pUnit:GetDamage() + unitDamage) >= 100 then
    table.insert(tKillUnits, pUnit)
   else
    pUnit:ChangeDamage(unitDamage)
    print("inflicted "..unitDamage.." to unit")
   end
  end
 end
 --now we've completed the iteration through table pUnits:Members() and can safely delete units listed as members
 for k,pUnit in pairs(tKillUnits) do
  pUnits:Destroy(pUnit)
  print("a unit was destroyed because of attrition")
 end  
end

 end

  TerrainAttritionMul = TerrainCataMul
  if feedBack then
   Game.AddWorldViewText(0, "A catastrophe happened to this unit while moving", UnitX, UnitY, 0)
  end
 end

 if experienceFromCata then

    local currentXP = pUnit:GetExperience()
    local currentXPPoints = currentXP:GetExperiencePoints()+5
    --currentXPPoints = currentXPPoints+5
    local experienceChangeAmount = math.random((BaseAttritionMin/10)+1,(BaseAttritionMax/10)+1)
    currentXP:ChangeExperience(experienceChangeAmount)
   end
  end
 end 
end
Events.UnitMoved.Add(Attrition)
Now looking forward suggestions.
I added a feature that gives a few XP to a unit if a catastrophe happens when the unit moves. For a little RPG feel :-)
Cheers.
