Meat Hook

I was following this on how to implement Daelin's Meat hook (Linky), but there are three things that I would like to do that this does not include instructions on how to perform...

1. How do I implement damage (I need it for 2 levels)?
2. How do I increase the frequency with which these spawn (" ")?
3. How do I increase range per level (" ")?

Assuming you know basic jass...

create some variables

integer SL = GetUnitAbilityLevel
integer DMG = 100 * SL

1. UnitDamageTarget( , ,DMG, , , , , ,)

2. I think you mean this... change 0.035
call TimerStart(t, 0.035, true, function MeatHookCreate)

3.change
return 1000.00 //maximum range of hook
into
return 500*SL //maximum range of hook

Hope this helps

... And assuming I don't know basic jass? xD
