How to Write Checking Unit In Range code

[Kelvin87]

Can somebody help me to write the code of checking the unit come in a range of Triggering Unit and want the Triggering Unit to attack it if the coming unit is an enemy...

 

[LightChaosma]

does this apply to one unit, or more units? GUI or MUI?

This code is used for a group of units. So, how you do it? In custom code prefered...

wouldnt know that... i dont know any custom codes but leak removers... if it was a single unit i would be able to help... too bad

well the unit you call Triggering Unit should be put in a variable(in this case unit) in another trigger because you can't have a unit respond to(trigger) an even inside the event. In this code the triggering unit is the unit that comes in range of the one you call Triggering Unit.

function unitEnemy takes nothing returns boolean
    return(IsUnitEnemy(GetTriggerUnit(),GetOwningPlayer(udg_unit)))
endfunction

function Trig_trigger_Actions takes nothing returns nothing
    local unit c = GetTriggerUnit
    local unit u = udg_unit
    call IssueTargetOrder(u, "attack", c)
endfunction


//===========================================================================
function InitTrig_trigger takes nothing returns nothing
    set gg_trg_trigger = CreateTrigger(  )
    call TriggerRegisterUnitInRange( gg_trg_trigger, udg_unit, 256 ) 
    call TriggerAddCondition(gg_trg_trigger, Condition(function unitEnemy))
    call TriggerAddAction( gg_trg_trigger, function Trig_trigger_Actions )
endfunction

256 is the range.
