Hi,

Can the following transport trigger result in lags? E.g. if the AI has many units and transports? Its an old and ugly trigger so it can result in eye cancer:

  • AI transport load units
    • Events
      • Time - Every 8.00 seconds of game time
    • Conditions
    • Actions
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • (Player 2 (Blue) controller) Equal to Computer
          • AI_Player2_Air Equal to 1
        • Then - Actions
          • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            • If - Conditions
              • (Number of living Aurochs units owned by Player 2 (Blue)) Greater than 0
            • Then - Actions
              • Custom script: set bj_wantDestroyGroup = true

It leaks so it can cause game performance to degrade over time.

These lines leak...
  • (Number of living Aurochs units owned by Player 2 (Blue)) Greater than 0
  • (Number of living Broodmother units owned by Player 2 (Blue)) Greater than 0
  • (Number of living Overlord of the Void units owned by Player 2 (Blue)) Greater than 0
All of them leak a handle reference index as a result of the "local declared local handle reference counter leak on return" error.

JASS: 
function CountLivingPlayerUnitsOfTypeId takes integer unitId,player whichPlayer returns integer
    local group g
    local integer matchedCount
    set g = CreateGroup()
    set bj_livingPlayerUnitsTypeId = unitId
    call GroupEnumUnitsOfPlayer(g, whichPlayer, filterLivingPlayerUnitsOfTypeId)
    set matchedCount = CountUnitsInGroup(g)
    call DestroyGroup(g)
    return matchedCount
endfunction
As can be seen above, the local declared local group g is set to a new group, the group is destroyed but the variable is not nulled. As such the handle index used by the group cannot ever be recycled. Below a fixed version of the BJ is provided.

Hi ty for the fast reactions,

I actually have unit indexer trigger (right below, not selfmade though), is that enough for counting units entering/exiting the map? Could I use that to delete the leak?


This trigger works in two key phases:

1) During map initialization, enumerate all units of all players to give them an index.
2) Adds a second event to itself to index new units as they enter the map.

As a unit enters the map, check for any old units that may have been removed at some point in order to free their index.

, forgive my noobness; how can I implement/use this? Should I copy the fixed function to the custom map script window?

Unit Enters Region (Entire Map Area), increase count and on death decrease count. Provided nothing else happens with the unit that should change the count. Or you could copy Dr Super Goods fixed function (might need to change the name) into the map header and call it via a custom script before checking the conditions.

Hi, get 2 errors, 1 is 'invalid number of arguments' and an 'expected endif'. I have copied Dr Super Good fixed function to the header;


JASS: 
//===========================================================================
// Fixes leak for pick every unit condition

function FixCountLivingPlayerUnitsOfTypeId takes integer unitId,player whichPlayer returns integer
    local group g = CreateGroup()
    local integer matchedCount

    call GroupEnumUnitsOfPlayer(g, whichPlayer, filterLivingPlayerUnitsOfTypeId)
    set matchedCount = CountUnitsInGroup(g)
    call DestroyGroup(g)
    set g = null
    return matchedCount
endfunction


And placed the custom script for each condition.

If you look into the function you have copied:
JASS: 
function FixCountLivingPlayerUnitsOfTypeId takes integer unitId, player whichPlayer returns integer

Note in the code above that it takes these parameters (unitId and whichPlayer) so you need to pass it into the function just like any other GUI function.

- Create a new variable of type integer and call it tempCount
- You need to use it by declaring (setting) a variable to to the value returned. So in your custom script: set udg_tempCount = FixCountLivingPlayerUnitsOfTypeId ('hhou', Player(1)). In this example I'm counting number of farms for player blue. So find the UnitId-code for your units. (Go into the object editor menu and press ctrl+d.)
- After that in your if-statement only check if tempCount > 0
- Repeat the process only changing the unitId in the parameter.

Note that you can use this variable any time you want to count something temporarily.

Your farm example works. But I am now having trouble getting it to work with custom units (in this case the unit is based on the human gyrocopter / flying machine):

  • Custom script: set udg_tempCount = FixCountLivingPlayerUnitsOfTypeId ('h001:hgyr', Player(1))
Thanks for your patience by the way.

A unit-id is always 4 characters. In this case 'h001' is the id and 'hgyr' is what you copied.

Oh that makes sense. Thanks. I have one final question than I promise to shut up and give +rep :grin: :

If I want to send picked player instead of e.g. player(1) how to do that?

I tried through player variable and string variable but both give an expected name error:

  • Set tempPlayer = (Picked player)
  • Custom script: set udg_tempCount = FixCountLivingPlayerUnitsOfTypeId ('h001', tempPlayer)
  • Set tempPlayer = (Name of (Picked player))
  • Custom script: set udg_tempCount = FixCountLivingPlayerUnitsOfTypeId ('h001', tempPlayer)
