[General] Randomizing Regions

[RiotZ]

So I run a trigger that spawns shit in a region, then, when someone enters said region, it triggers a bunch of stuff.

What I want to do, is make said region, random, so that, you don't go to the same region every time.

There are two methods I know of, both of which, do not work.

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (Random integer number between 1 and 100) Less than or equal to 25
  • Then - Actions
    • Set MissionRegion[1] = Helicopter Roof Landing <gen>
    • Set MissionRegion[2] = Scientist Spawn <gen>
  • Else - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Random integer number between 1 and 100) Less than or equal to 25
      • Then - Actions
        • Set MissionRegion[1] = Scientist Spawn 2 <gen>
        • Set MissionRegion[2] = Trucks Area <gen>
      • Else - Actions

This is the first. It does not work, because variables cannot be detected via, a unit enters region.

The second method, is to do this...

• Region - Center Trucks Area <gen> on (Center of Scientist Spawn 2 <gen>)

Moving regions works, but you can no longer detect entry, when you move a region, entry into that region, will still be detected wherever the region was originally. I.e., you move Region 1 from Point 1 to Point 2, going to Point 2 will not detect entry, but going to Point 1 will, since the region originally resided at Point 1, and due to some Blizzard dick up, you can't move regions 100%.

Does anyone know a workaround, because this is pissing me off.

Thanks in advance.

You could just make an entry event for all of those regions, then use a variable to determine which one is active

Like

• Events
  • A unit enters REGION1
• Conditions
  • Variable: WhichRegion is equal to 1
• Actions

• Events
  • A unit enters REGION2
• Conditions
  • Variable: WhichRegion is equal to 2
• Actions

and so on...

So all of them have been set-up, but only 1 region will be "active", depending on the value of the variable...

Or you can also opt to use a single dummy unit, then use the event A unit enters within XXX of unit... then just move that unit elsewhere to change regions... this is assuming, all regions have same size...

Can't you just create new regions dynamically? I think you can do it in JASS at least.

function makeRegion takes nothing returns region
  local region myRegion = CreateRegion()
  local rect myRect = Rect(GetRandomReal(x,y), GetRandomReal(w,z), GetRandomReal(u,v), GetRandomReal(p,q))
  call RegionAddRect(rect)
  return Region //returns a handle to the randomly created region
endfunction

My understanding (from JASS) is that Regions themselves are just the union of some set of rects (2-d quadrilaterals). So I guess it would make sense that moving a region doesn't really do anything, because the rects that make it up didn't move at all. But I could be completely wrong, as I just started learning this stuff.

 

[Adiktuz]

@seth - Regions in GUI are the Rects of JASS...

Also, his regions are already predetermined so I don't think suggesting to dynamically create regions is a good idea, there's just no point in doing it... anyway, my suggestion I think would be enough for what he wants...

now if he wants it to be SO random, then yeah we can simply dynamically create a new one, destroy old trigger and make a new one for the new region (destroy the old to make it efficient)

I suppose this is the only decent way.

this is not entirely true
you can add a new event to detect variables like this below

• Trigger - Add to YourTrigger the event (Unit - A unit enters Region[1])

I just tried this, and it works in the GUI script, now let me just see if it works in game. O:

if you have any problem
post the triggers here

I had a "enter region" system, I modified it a bit.

Triggers InitR Events Map initialization Conditions Actions Custom script: local region r -------- ---------------------------------------------- -------- Hashtable - Create a hashtable Set RectHash = (Last created hashtable) -------- ---------------------------------------------- -------- Set Trig = EnterR <gen> -------- ---------------------------------------------- -------- Set RectEnter[0] = Region 003 <gen> Set RectEnter[1] = Region 003 Copy <gen> Set RectEnter[2] = Region 003 Copy 2 <gen> -------- ---------------------------------------------- -------- For each (Integer A) from 0 to 2, do (Actions) Loop - Actions Custom script: set r = CreateRegion() Custom script: call RegionAddRect(r, udg_RectEnter[bj_forLoopAIndex]) Custom script: call TriggerRegisterEnterRegion(udg_Trig, r, null) Custom script: call SaveRectHandle(udg_RectHash , GetHandleId(r), 0, udg_RectEnter[bj_forLoopAIndex] ) Custom script: call SaveRegionHandle(udg_RectHash , 0, bj_forLoopAIndex, r) -------- ---------------------------------------------- -------- Custom script: set r = null -------- ---------------------------------------------- -------- Trigger - Run RandomReg <gen> (ignoring conditions) RandomReg Events Conditions Actions Custom script: call SaveRegionHandle(udg_RectHash , 1, 0, LoadRegionHandle(udg_RectHash, 0, GetRandomInt(0, 2))) EnterR Events Conditions Actions Custom script: if GetTriggeringRegion() == LoadRegionHandle(udg_RectHash, 1, 0) then Game - Display to Player Group - Player 1 (Red) for 5.00 seconds the text: ZOMG! Trigger - Run RandomReg <gen> (ignoring conditions) Custom script: endif

Remember to configure the GetRandomInt(0, 2), change the 2 to the max index used in the region array.
