A weapon that dispenses AI? [Solved]

woner11 · Post by **woner11** » Thu Apr 17, 2008 10:59 pm

I'm not sure how many of you have played negative zone city or whatever, but I noticed a weapon which puzzled me how to make. The wampa on there had a weapon which when pressed made four unplayer controlled wampas spawn around him and I was wondering how it was done. Thanks in advance.

What you do is insert coding similar to this:

Code: Select all

TroopSpawnerWeapon = "rep_item_powerup_cura"

   OnCharacterDispensePowerup(
      function(character,powerup)
         if GetEntityClass(powerup) == GetEntityClassPtr(TroopSpawnerWeapon) then
            local SupportTeam = 3 --Team the new spawned character is in (change this)
            local teamSize = GetTeamSize(SupportTeam)
            for i = 0, teamSize-1 do
               local characterIndex = GetTeamMember(SupportTeam, i)
               local charUnit = GetCharacterUnit(characterIndex)
               if not charUnit then
                  local destination = GetEntityMatrix(GetCharacterUnit(character))
                  SpawnCharacter(characterIndex,destination)
               end
            end
         end
      end
	   --User team (change this)
      )

Into the ScriptPostLoad of your .lua. Then add a third team with the to-be-spawned unit, like this:

Code: Select all

    SetTeamName (3, "summon")
    AddUnitClass (3, "rep_inf_ep2rifleman", 3,4)
    SetClassProperty("rep_inf_ep2rifleman", "AddHealth", -100)
    SetUnitCount (3, 4)
    AddAIGoal(3, "Deathmatch", 100)
    SetTeamAsFriend(ATT,3)
    SetTeamAsFriend(3,ATT)
    SetTeamAsEnemy(DEF,3)
    SetTeamAsEnemy(3,DEF)
    SetTeamName(3, ATT)

Then create a null dispenser weapon (note that the weapon is called rep_weap_summon, but it's the powerup that it dispenses - rep_item_powerup_cura - that triggers the actual code) - it does nothing, it's just used to trigger the .lua code above.

Something like that? Except you would need to change the team condition to a GetLastHitWeapon() condition.

Does this still do damage to the target, because if so, then its perfect!

MasterSaitek009 · Post by **MasterSaitek009** » Fri Apr 18, 2008 11:33 pm

You set the damage in your ODF.
Make sure to credit Zerted for it. He really did most of it.

I'll give it a try and see how it all works out. Just a few quick questions about it as I am not good with most of this lua stuff other than characters, mainly because I hardly ever do it.
What does the 2 part mean?

Whre in the whole code do I insert my character name? Lets say its cis_hero_darth and he is the sniper does it work like this?

             if damager == nil then return end
             if GetCharacterTeam(damager) == DEF then

                 end
             end
         end
            )

The function OnObjectDamage receives the damaging unit which it contains in the variable damager.

Code: Select all

if GetCharacterTeam(damager) == DEF then

This check if the damager is on the DEF team. Change it to the team that your unit is on.

Code: Select all

if GetCharacterClass(damager) == 2 then

This checks the index of the damagers class. The number should be how far down(starting at 1) on the team setup the unit is.
I had this setup for a unit with only one weapon, so I didn't have to check for the last hit weapon. You'll have to.
Try this:

Code: Select all

OnObjectDamage(
         function(object, damager)
             if damager == nil then return end
             if GetObjectLastHitWeaponClass(object) ~= "YOUR_WEAPON_NAME" then return end   -- ~= means not equal to
                     local unit = GetCharacterUnit(damager)
                     if unit == nil then return end
                     SetProperty(unit, "CurHealth", GetObjectHealth(unit) + 1) --adjust + 1 to your preference
          end
            )
