Text tied to units + expires Lots of help needed

[LilBlueSmurf]

The basic overview of what I am trying to do is this:
When the function is run it creates a textag above a unit.
A periodic timer is made that will update the text to the unit's position every 0.02 seconds as well as changing the text to the units custom value.
After <waitTime> the text and timer are destroyed.

I don't know lag wise if it helps to change the tags instead of destroying/creating new ones each time but I am guessing it does.

Basically what I'm going for is you click a unit and it displays a number overhead that increases each time you click for X time, then something happens and the process would start over. Multiple players will be clicking on multiple (different) units at the same time though.

My obviously non working, probably not much use to start with code/pseudo code is this:

    function refreshCounter takes unit target, texttag t returns nothing
       local point tempPoint = GetUnitLoc(target)
       set t = I2S(GetUnitUserData(target))
       call SetTextTagPosBJ( t, tempPoint, 10.00 )
       call RemoveLocation(tempPoint)
    endfunction

    function killCounter takes timer pTimer, texttag t returns nothing
       call DestroyTimer(GetExpiredTimer())
       call DestroyTimer(pTimer)
       call DestroyTextTag(t)
    endfunction

    function newCounter takes unit target, real w returns nothing
       local timer pTimer = CreateTimer()
       local texttag t = CreateTextTagUnitBJ(I2S(GetUnitUserData(target)), target, 10, 11, 80.0, 80.0, 100.0, 0 )
       call SetTextTagVelocityBJ( t, 0, 0 )
       call SetTextTagPermanentBJ( t, true )
       call TimerStart(pTimer, 0.02, true, function refreshCounter(target, t))
       call TimerStart(CreateTimer(), w, false, function killCounter(pTimer, t))
    endfunction

I am coming back after a long time away so I am horribly rusty and didn't even realize you can't pass variables when you do the "function xxx" stuff. If it is easier to start from scratch please free to do so. I don't expect anyone to totally write this for me (unless you feel like it) but I obviously need some big help.

I'd suggest to get your hands on a timer system. It's easier to manage and pretty much works fully for you.

I know you're rusty, however you gotta start somewhere right? So you might aswell start at understanding a system and how to use it.

Actually I figured out an easy way to do this by just adding units to a group and cycling through them, way quicker to code. I am not going to say 100% this is solved though as I haven't tested the simple way out much so it may have problems.
