[JASS] UNITA in range of UNITB question!

[KhaosMachine]

How can I trigger the UNIT on this example?

TriggerRegisterUnitInRange(trig, UNIT, 80, null)

I tried with

GetTriggerUnit()

but it check the entering unit

The only solution for this that I know of is to make a periodic timer which checks the distance between those 2 units (A & B).

Create a different trigger per unit and attach it to the same. There is GetTriggeringTrigger().

Definitely is not clear your question. What do you want to do with this?? Get distance?? detect unit entering the range??

Detect the unit of the CENTER of the range, no the entering unit, the AXIS unit...

This was graveyarded a while back but it can solve your problem.

It isn't the most efficient solution (it is actually pretty whacky), but it works. You can also just use waterknight's method, you just need to save the unit in a hashtable under the trigger id. Then in the actions you can load the unit under the handle id of GetTriggeringTrigger()

EDIT: Untested and made in textedit so I don't know if it even compiles. However, it should work.

Instead of the normal event, just use TriggerRegisterUnitInRangeEx(trigger, source, range, filter)

Then in the actions, use GetTriggerSourceUnit()

However, you can only register one TriggerRegisterUnitInRangeEx() per trigger. Good luck.

library TriggerSourceUnit
	globals
		private hashtable hash = InitHashtable()
	endglobals

	function GetTriggerSourceUnit takes nothing returns unit
		return LoadUnitHandle(hash, 0, GetHandleId(GetTriggeringTrigger()))
	endfunction

	function TriggerRegisterUnitInRangeEx takes trigger t, unit source, real range, boolexpr filter returns boolean
		call SaveUnitHandle(hash, 0, GetHandleId(t), source)
		return TriggerRegisterUnitInRange(t, source, range, filter)
	endfunction
endlibrary
