[Trigger] Get Entered Region?

[Yixx]

Hello people,,

Is there any way of checking Which region is entered?
I got a trigger that uses (now only 15 but is going to use) about 500 events (whenever you enter a house, but there are loads of houses over the map)
Is there any way of checking which region was entered? Without using a variable array that i have to set manually, cause i have done that so far, but it is annoying -.-

Anyone knows? Jass or GUI, doesnt matter
Thanks!

Well this is the only way using events sad but true

 

[Yixx]

Yeah but i mean:
I got a trigger that has 2 events(for example):

• EnterHouse
  • Events
    • Unit - Unit enters House1
    • Unit - Unit enters House2
  • Conditions
  • Actions
    • My actions

How do i know which region it entered? Cause if it entered House1 i need to do some actions, if House2 it needs to do other actions
Any way? Jass is also accepted, Even a long long code, as long as there is an explanation how to use,,

I think he understands, but sadl, there aint much 8of a way out.

Unless you could do a "pick every unit in region" and then if the picked unit was the triggering unit, you would know wich region he entered.

• EnterHouse
• Events
  • Unit - Unit enters House1
  • Unit - Unit enters House2
• Conditions
• Actions
  • For each interger (A) from 1 to (House_count) do actions:
    • Actions - loop
      • Unit Group - Pick every unit in (House_entrance(For loop integer A)
        • Actions - Loop
          • If / then / else - If (picked unit) equal to (triggering unit)
            • Then - actions
              • Unit - Move triggering unit instantly to center of (House_Arrival(For loop interger a)
              • Else - actions

Look Yixx u got to do every Region it's actions, this cannot be avoided.. so there is no solution

 

[Yixx]

Ah damn, so i will have to set every region manually in a variable array?
That really sucks! D=<
Well, thanks for help anyway! +rep

 

[Lord_of_sausage]

Im not sure now, in fact, i think the trigger i posted could work... if it make your life easier, ofcause

 

[Yixx]

Well, in fact, i used that sort of trigger already, but i will get really tired of setting about 500 region variables,, so i thought maybe some other way,,
But as you guys say, not possible,,
Thanks anywayz,,

constant native GetTriggeringRegion takes nothing returns region

I found this one. I havent really used regions, so I dont know if it is rect what you need or a region, but I hope this helps.

 

[Yixx]

Oh nice =D,,
But how to use it?

set udg_Region = GetTriggeringRegion()
// that doesnt work
set udg_Region = GetTriggerRegion()
// also doesnt work

How to use then? =\

 

[Lord_of_sausage]

I think he needs a rect, sadly. Rect = region in Jass, if im right (not sure if i am xD).

 

[Yixx]

Omg ya,,

Ok, tried:

set udg_Region = GetTriggeringRect()
set udg_Region = GetTriggerRect()
//sadly both dont work

There is a little trick to get the coordinates faster: get jasscraft, or any programm where you can open/extract the .j file out of your map...

There the coordinates are listed for the globals ... helps a bit with many regions (copy-paste)

The problem is:
the corespondending event to GetTriggeringRegion() is: EVENT_GAME_ENTER_REGION
but you usually dont use that event, but call TriggerRegisterEnterRectSimple( trigger, region )

-> you only get the unit of that event... and there is no real (Is that the event rect)-function


I actually uses this solution: But u need all regions in an array!

I maybe public the full code of the triggers later... actually working on them

  local integer i = 0
  local integer triggeringRectId = 0
  local unit triggeringUnit = GetTriggerUnit()

  //Wait untill unit is really in - Bugs without, when entering from top...no clue why ;)
  call TriggerSleepAction(GetUnitMoveSpeed(triggeringUnit)/2000)

  //Get triggeringRectId
  set i = 0
  loop  
    exitwhen i>3 
      if ([B]RectContainsUnit[/B](udg_zRegion[i],triggeringUnit)) then
        set triggeringRectId = i
      endif
    set i = i+1
  endloop

 

[Yixx]

Why would i need coordinates?
I need to check which region is entered,,
(or if you did understand me but i didnt understand you, please explain yourself)

 

[Iluya]

Basically i haven't found any direct solution to get the region entered.

Problem:
That what in the World Editor is a region is in the Jass code a rect. They check if a unit enters a rect, they check if the unit is in the rect! That is why there are no jass functions for eventhanling a region.

The funtion the WE uses for "unit enters region" is:

function TriggerRegisterEnterRegionSimple takes trigger trig, region whichRegion returns event
    return TriggerRegisterEnterRegion(trig, whichRegion, null)
endfunction

The WE registers a region...dont know why he can, cause the variable is as rect defined...

As far as i have seen the regions (in jass) are collection of many rects...which may can be used for some purposes, but im not that informed about that. There are some functions for that:

native RegionAddRect            takes region whichRegion, rect r returns nothing
native RegionClearRect          takes region whichRegion, rect r returns nothing

native RegionAddCell           takes region whichRegion, real x, real y returns nothing
native RegionClearCell         takes region whichRegion, real x, real y returns nothing

native IsUnitInRegion               takes region whichRegion, unit whichUnit returns boolean

I think i got a better solution =)
What i need it for:
When you enter a house, i need to know which house, so you dont get in one house, and exit some other,,
I thought: Set it into a variable and move it to that region when exiting,,
But why dont i set the position of the unit in a variable and move it to that point when exiting? =D,,
Well, i thank you all for replying!
+rep!

Still too bad there is no 'GetTriggeringRect' =(
