How to choose the closest unit.

Hi. I was wondering how I would choose the closest unit to index as the target in the hashtable.

    • Unit Group - Remove all units from FieryClawsCaster_UGrp

Now I just want to look over the section that involves the targets unit group. I don't know how to use the distance from here.
Edit: And ty!

My ability isn't currently working but I'm seeing improvements. the damage done is usually more then 50 (bug), the spell doesnt have Multi instanceablity yet for some reason, is this becuase the targets unit group isnt put into a group handle in a hashtable instead of a unit group variable? anyways anything that is pointed out would help me alot.

Hi. I was wondering how I would choose the closest unit to index as the target in the hashtable.

with pick all unit in x range going like this:

pick all unit in 600 range

unit = picked unit
index=index+1
so u can save unit handle like( hashtable key1(something), key2: index, unit)

 

[Space_Ship]

Are the index and the unit 2 different variables? or does the unit variable have an index. (Array type)

convert trigger to custom text


UG=unit group variable
Target_Table=hashtable variable

    local unit u = GetTriggerUnit()
    local unit pu
    local player p = GetTriggerPlayer()
    local real x = GetUnitX(u)
    local real y = GetUnitY(u)
    local integer index = 0
    local integer cv = GetUnitUserData(u)
    call GroupEnumUnitsInRange(udg_UG, x, y, 600.00, null)
    loop
        set pu = FirstOfGroup(udg_UG)
        exitwhen (pu==null)
// if dont need if u dont want filter the unit
//        if IsUnitAlly(pu, p)  then 
                
             call SaveUnitHandle(udg_Target_Table, cv, index, pu)
             set index = index + 1
//        endif
        call GroupRemoveUnit(udg_UG, pu)
    endloop

    set u = null
    set p = null
    set pu = null

i have no ideea why u need hashtable when u can use unit variable

    local unit u = GetTriggerUnit()
    local unit pu
    local player p = GetTriggerPlayer()
    local integer cv = GetUnitUserData(u)
    local real x = GetUnitX(u)
    local real y = GetUnitY(u)
    set udg_index = 0
  
    call GroupEnumUnitsInRange(udg_UG, x, y, 600.00, null)
    loop
        set pu = FirstOfGroup(udg_UG)
        exitwhen (pu==null)
                
//i removed the if but u can put back if u want

             set udg_Target[cv] = pu
             set udg_index[cv] = udg_index[cv] + 1

        call GroupRemoveUnit(udg_UG, pu)
    endloop

    set u = null
    set p = null
    set pu = null

index is integer variable array
Target is unit variable array
so then u can loop from 0 till index for get every target
