TRIGGER request

[Darkshine]

Hello people! Someone can do for me a trigger that allow me limit the max number of a specific existing unit in the map (eliminating the oldest one when the limit is break)

Basically, i have a unit in my map that can build little attacking turrets, however, i want limit this turrets, so, the player only can have X of them in the map at the same time. When he build another turret in other place, the oldest turret is destroyed.

Somebody can do it? Thanks.

I shall try

Heres my first shot shot, but it will work for all players at the same time, not for each player. That would need the use of Hashtables and I don't know how.

First Shot

Unit Type Array: Turrets
Integer variable: TurretQ (Turrent Quantity)

1) A unit builds a Turret
-> Set TurretQ = TurrestQ + 1
-> Set Turrets[TurretQ] = last created turret.
2) If/Then Else
-> If: TurretQ = 10
-> Set TurretQ =TurretsQ - 1
-> Unit - Remove Turrets[1]
-> For each integer A from 2 to 10 do:
-> Set Turrets[Integer A] = Turrets[Integer A - 1]


3) A unit Dies
If: Unit-Type of Triggering Unit = Turret
-> Set TurretQ = TurretQ - 1

- However, maybe the tower that died wasn't the Turret[1] so, this doesn't work =)
------------------------------------------
Example:

When you build the Turret #10, the Turret[1] Will be destroyed, and Turret[2, 3, 4, 5, 6, 7, 8, 9 10] will be reduced by 1, making their values to Turret[1, 2, 3, 4, 5, 6, 7, 8, 9]. And will loop over and over.

My second Shot: Using Custom Value.

Second Shot

I'm thinking about it <- I have no idea xD

Hash

1) A unit builds a Turret
-> Set TurretQ[Triggering Player Index] = TurrestQ[Triggering Player Index] + 1
-> Save last created turret as TurretQ[Triggering Player Index] of Handle Trigger Player in TurretHash
2) If/Then Else
-> If: TurretQ[Triggering Player Index] = 10
-> Set TurretQ[Triggering Player Index] =TurretsQ[Triggering Player Index] - 1
-> Unit - Remove Load 1 of Handle Triggering Player in TurretHash
-> For each integer A from 2 to 10 do:
-> Save (Load IntergerA of Handle Triggering Player in TurretHash) as IntergerA - 1 of Handle Trigger Player in TurretHash


3) A unit Dies
If: Unit-Type of Triggering Unit = Turret
-> Set TurretQ[Triggering Player Index] = TurretQ[Triggering Player Index] - 1

So, this is the full trigger? Someone can do a test map?

 

[Spartipilo]

Maybe you?

Do not use hastables they bug and are slow

 

[Narogog]

you could use an array instead,

local integer i
local player p
local unit u
set p = GetTriggerPlayer()
loop
   exitwhen i > 12
   set i = i+1
   if player(i) == p then
      call GroupAddUnit(GetTriggerUnit(),TurretsGroup[i])
      if turrets[i] == turretsmax then
         set u = FirstOfGroup(TurretsGroup[i])
         call GroupRemoveUnit(u,TurretsGroup[i]) // this part has to be custom script nothing else does.
         call RemoveUnit(u)
      else
         set turrets[i] = turrets[i]+ 1
      endif
     endif
endloop
set p = null

this is for when a unit dies (i think this will work)

local player p
local integer i
set p = GetTriggerPlayer()
loop
   exitwhen i > 12
   set i = i+1
   if player(i) == p then
      set turrets[i] = turrets[i] - 1
      call GroupRemoveUnit(GetTriggerUnit(),udg_TurretsGroup[intger A]) 
   endif
endloop
set p = null

the only thing is I am concerned that this might create null values in the unit group and it won't actually remove a turret it(in the first loop) instead it will remove a null value.
edit: updated code

Narogog could you please use [ JASS ] [ /JASS] texts when posting code, its much easier on the eyes
