[Trigger] Creating a region through triggers?

[ShadowMan]

Evenin' all, I'm here with yet another question.

Is it possible to create regions through triggers? 'Cause there aren't any actions in GUI, I'll assume that it is in the JASS corner... Either that or it isn't possible. Either way, some insight on the subject would be nice.

The reason I am asking this is because I am trying to make a unit that checks the surrounding area for allied units and then protects them, and when they leave the area, the protection is lost.

Example. A unit comes within 3000 of Protector - give protection
A unit with protection walks to 3001 from protector - remove protection

As always, solutions or tips are appreciated and if it really helps i'll give you some +rep

Well, you can do it in GUI if you have a region variable.
You can specify a region using coordinates.
When you go to Set Variable with the region variable, check out the option Conversion - Convert Coordinates to Region.

 

[ShadowMan]

Cool, I knew that... But I had totally forgotten about it.
Is Conversion - Convert point with size to region a circular region?

> Is Conversion - Convert point with size to region a circular region?

No. It's a region with a point as a center, then you give it a width and height.

 

[ShadowMan]

So... there's no way of making a circular region?
Although a square region will suffice, I'd rather use a circular one because it's more accurate imo.

No. Not possible as far as I know.
You can pick units within a circular area or so, but not create a region.

Why don't you just use aura and detect if unit is under it's effect or not?

 

[ShadowMan]

Alright, thanks for the useful information. +rep
Any solutions to my trigger, while you're at it?

 

[ShadowMan]

Hm, I thought about that, but didn't really know how the trigger would look like. I want it to be as efficient as possible, so the less variables the better.

Edit: How about a trigger that checks if the unit doesn't have the aura effect and has the Protection (its an ability), or rather, if the unit has protection and then check if it is outside range, more efficient for the trigger to read I would think.

The one with aura?

• Aura Invurnerability
  • Events:
    • Time - Every 0.1 seconds of game time
  • Conditions:
  • Actions:
    • Custom script: set bj_WantDestroyGroup = true
    • Unit Group - Pick every unit in (entire map) and do (Actions)
      • If Then Else - Multiple Functions
        • If - Conditions:
          • (Picked unit) has buff Your_Buff Equal to True
        • Then - Actions:
          • Unit - Make (Picked unit) Invurnerable
        • Else - Actions:
          • Unit - Make (Picked unit) Vurnerable

EDIT:
@Up
Edit your posts, dont double post.
You want to check if unit doesn't have an aura effect and have an ability? This should look like this:

• Conditions:
  • [unit] has buff [buff] Equal to False
  • (Level of [ability] for [unit] greather than or equal to 1)

> That trigger

Big leak problems there....
For the love of your map, look up some leak tutorials for that trigger.

 

[raft_pl]

Oh, thanks you pointed that, Ghan

Fixed.

 

[ShadowMan]

That would not be very smart. Picking all units in the entire map every 0.1 (or 0.5 or whatever) would eventually cause a major lagg. Can it be simplified, or improved? I can't seem to find the condition for if "unit has ability", maybe I imagined it...

Edit: Sorry for double posting, I just love making posts ..

• Conditions:
  • [unit] has buff [buff] Equal to False
  • (Level of [ability] for [unit] greather than or equal to 1)

There it is! That's the condition I was looking for. Thanks +rep to you for teh trigger and stuff

I'll post you my version of the trigger in a moment...

 

[raft_pl]

Dont post map, i dont have w3 right now...
And no, it wont cause lagg, because it just picks the units and does only one action, and then removes the group leak.

 

[ShadowMan]

Actually, you wanna use the Pick every unit in (Playable map area) matching condition as it is more appropriate imo

By the by, if the level of an ability is equal to 0 does that mean that the unit doesnt have the ability?

 

[raft_pl]

As far as i understand, playable map area doesnt include cliffs, etc, so entire map lets you pick flying units at those places.

Yes, because units cant have a 0-leveled ability. Its logical for me

 

[ShadowMan]

Yes Yes, I was just giving you a better action, wasn't referring to the point itself rather than the action with a condition modifier

Great then my trigger is complete. Yay *Cheers*

 

[ShadowMan]

Ok, so the trigger doesn't work... Can anyone tell me what's wrong with this trigger?

• Shield Buildings and Units
  • Events
    • Time - Every 0.05 seconds of game time
  • Conditions
  • Actions
    • Unit Group - Pick every unit in (Units in (Entire map) matching (((Level of No Damage Book for (Matching unit)) Equal to 1) and (((Matching unit) has buff Town Shield ) Equal to False))) and do (Actions)
      • Loop - Actions
        • Unit - Remove No Damage Book from (Picked unit)
    • Unit Group - Pick every unit in (Units within 3000.00 of (Position of uniShieldActivater) matching ((((Matching unit) is A structure) Equal to False) and (((Matching unit) belongs to an enemy of (Owner of uniShieldActivater)) Equal to False))) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • And - All (Conditions) are true
              • Conditions
                • (Level of No Damage Book for (Picked unit)) Equal to 0
                • ((Picked unit) has buff Town Shield ) Equal to True
          • Then - Actions
            • Unit - Add No Damage Book to (Picked unit)
          • Else - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • boolShieldBuilding Equal to True
      • Then - Actions
        • Set boolShieldBuilding = False
        • Unit Group - Pick every unit in (Units within 3000.00 of (Position of uniShieldActivater) matching (((Matching unit) is A structure) Equal to True)) and do (Actions)
          • Loop - Actions
            • Unit - Add No Damage Book to (Picked unit)
      • Else - Actions

Explanations: No Damage Book is the ability that make units invincible, Town Shield is the aura buff, boolShieldBuilding is a boolean that only activates once, and uniShieldActivater is the unit triggering.

What exactly is it that does not work?

You could try to put in some Game - Text Messages there and see where the problem lies.
