[Trigger] Spawn System w/o Building!

[KaiserG]

Ok, I already have a spawn system. But it's not working the way I want to. The system just spawns some units in <Playable Map Area> and they always spawn everywhere, even underwater and in the middle of a cliff! Is there any way to prevent this easily? I didn't tried by automatically moving the unit a little so it comes out of the cliff. Going to try and edit post while I wait for a good answer.

Here is the trigger:

Trigger:

• Spawn Stag
  • Events
    • Time - Every 15.00 seconds of game time
  • Conditions
    • (Number of living Stag units owned by Neutral Hostile) Less than 100
  • Actions
    • Set AntiLeakPosition = (Random point in (Playable map area))
    • Unit - Create 1 Stag for Neutral Hostile at AntiLeakPosition facing Default building facing degrees
    • Custom script: call RemoveLocation(udg_AntiLeakPosition)

Thanks in advance!

if its in the region it will spawn there, even if its water.

so, no, unless you make multiple regions that dont go on yhe water.

just as takakenji said, you need multiple regions. You make the anti-leak variable an array an select a random number from it.

You can use a pathability check function, but that also means you have to use JASS.

IsTerrainPathable(x,y,PATHING_TYPE_WALKABILITY) and not(IsTerrainPathable(x,y,PATHING_TYPE_AMPHIBIOUSPATHING))

x,y would be the coordinates.


Possibly PATHING_TYPE_BUILDABILITY too to make sure theres no structures in the way of it. But that might be atken care of with the placement.

well you could put pathing blockers in the places but that would take a long time if your map is huge. thats if you wanted to place the stags fully random or make lots of regions

ok good, my trigger is now converted into JASS and I've been able to stop the spawning in the water. But they keep appearing on the edge of cliffs, so they are unable to move.
Heres the full trigger:

function Trig_Spawn_Stag_Conditions takes nothing returns boolean
    if ( not ( CountLivingPlayerUnitsOfTypeId('n000', Player(PLAYER_NEUTRAL_AGGRESSIVE)) < 100 ) ) then
        return false
    endif
    return true
endfunction

function Trig_Spawn_Stag_Actions takes nothing returns nothing
    local location AntiLeakPosition
    set AntiLeakPosition = GetRandomLocInRect(GetPlayableMapRect())
    if (IsTerrainPathableBJ(AntiLeakPosition,PATHING_TYPE_WALKABILITY) == true) and (not(IsTerrainPathableBJ(AntiLeakPosition,PATHING_TYPE_AMPHIBIOUSPATHING) == true)) then 
       call TriggerExecute( GetTriggeringTrigger() )
    else
       call CreateNUnitsAtLoc( 1, 'n000', Player(PLAYER_NEUTRAL_AGGRESSIVE), AntiLeakPosition, bj_UNIT_FACING )
       set AntiLeakPosition = null
       call RemoveLocation(udg_Temp_Point)
    endif
endfunction

//===========================================================================
function InitTrig_Spawn_Stag takes nothing returns nothing
    set gg_trg_Spawn_Stag = CreateTrigger(  )
    call DisableTrigger( gg_trg_Spawn_Stag )
    call TriggerRegisterTimerEventPeriodic( gg_trg_Spawn_Stag, 5.00 )
    call TriggerAddCondition( gg_trg_Spawn_Stag, Condition( function Trig_Spawn_Stag_Conditions ) )
    call TriggerAddAction( gg_trg_Spawn_Stag, function Trig_Spawn_Stag_Actions )
endfunction

Oh and please if any moderator comes to this post. Change it to JASS!

Then you can check if the area around the point is pathable too.

 

[KaiserG]

hmm. not going to change. They appear in the middle of the cliffs edges so i dont think it would fix it. Anyway, not spawning on water is an advance.

 

[Kercyn]

Well, there's no way to spawn units in areas except those you decide to unless you use multiple regions :/

Set up an array of regions then spawn the deer based off a random integer.
