Most efficient way to set up a proximity trigger (I.e. triggered mine)

[Devalut]

Be it explosive goblin tech or restorative runes, whats the best way to trigger something like this?
Obviously barring the landmine ability, that's too one dimensional, and GUI would be preferred!

>What the #$%& are you on about?
X comes within range of Y, if so do effects, there is the basics of "Unit comes within range" however that's creating a trigger for each unique unit, and there's the periodic unit group check, but that has tick rate effects.

>You've just explained two ways of doing it, you turkey!
Yes, but I want to read other responses of those who are more experienced than I!
Lend me thy keyboard my dear fellows, weave a tale of your know how, and let us conjoin our thoughts into a nice thick toffee that sticks to ones teeth, a thought toffee, a thoffee?

You could always give it immolation and use a DDS

Brilliant!

For a periodical check to use a spell like Kaboom!, I'd go like this :

• Check for Kaboom
  • Events
    • Time - Every 0.17 seconds of game time
  • Conditions
  • Actions
    • Custom script: set bj_wantDestroyGroup = true
    • Unit Group - Pick every unit in (Units in (Playable map area) matching ((Unit-type of (Matching unit)) Equal to Goblin Sapper)) and do (Actions)
      • Loop - Actions
        • Set Unit_Location = (Position of (Picked unit))
        • Set Spotted_Enemies = (Units within (Unit: (Picked unit)'s Real Field: Acquisition Range ('uacq')) of Unit_Location matching (((Owner of (Picked unit)) is an enemy of (Owner of (Matching unit))) Equal to True))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Number of units in Spotted_Enemies) Greater than 0
          • Then - Actions
            • Unit - Order (Picked unit) to Neutral - Kaboom! (Random unit from Spotted_Enemies)
          • Else - Actions
        • Custom script: call RemoveLocation(udg_Unit_Location)

The range used for detection is set by unit acquisition range for realistic purposes

You can 'clear' a trigger of excess events by destroying and rebuilding it. That would be the easiest way to use the 'unit in range' event.

 

[Devalut]

@Pyrogasm
But would that be an efficient way?

 

[Tasyen]

One can also place an locust unit without model that can attack but deals no damage. When it triggers the is attacked event as attacker an unit comes in range of its pos. By using an min attack range one can also detect units in a donat.

 

[Pyrogasm]

Periodically checking in a radius around a unit isn't inefficient. Neither is destroying and rebuilding a trigger. Depends if a check frequency existing matters to you.

I'd go for the periodic check personally, but add all of the relevant "mines" into a unit group when they enter the map.

This way it'll only check the relevant units rather than having to find the relevant units each time if that makes sense. As a bonus you could turn the periodic trigger on/off when needed!
