Sleep+AOE+channel

[weuser]

So, I want to make a few different channeled ability (GUI), all of which are area of effect sleeps. They shouldn't be too hard but I can't crack it--every time I start thinking I know something about world editor it goes and makes me look foolish... Oh well, here are the abilities:

Ability One:
(1) Hero begins channeling Mass Sleep (the ability)
(2) Enemy units within targeted area fall asleep
(3) Any enemy who enters the area while channeling continues falls asleep
(4) They never wake up until channeling ends

Ability Two:
Same as Ability One but delete (3)

Ability Three:
Same as Ability Two but replace (4) with: They wake up when hit

Create a channelling ability.
Use a trigger that detects *starts the efect of an ability*
->your channelling ability
pick every units within range of xyz and use an if so set which unit shall not sleep (at least you need *picked unit = triggering unit is false)
then - depending on your other stuff -> either make unit sleep (with that, they autamatically should wake up when receiving damage) or cast the undead sleep on it via a dummy unit ->should last infinite

Now a 2nd trigger that detects when your caster finishes casting an ability and also tirggers when your caster stops.
Next pick again every unit in range and a) wake them up or b) remove buff (sleep -> for the undead version).

For every unit entering you sleep region use -> unit comes within range
-> make unit sleep or dummy unit cast sleep on triggering unit.
for unit within range you might store that point in a variable...

So far should work, if you only need 1 unit casting.
If you need it MUI, things must be done different - currently no clue (just back from uni and still brain dead )

Well I remember a spell I created longer time ago nearby the same as you need for your channel mass sleep. But before you use this:

1) Modify the "starfall" ability for the castable ability.
2) Then modify the "sleep" ability, so units can cast it, cost 0 mana, loong duration (is removed anyway when spell ends) and so on
3) At last create a dummy
4) Then c&p this code and change the configure-able things like you need it:

library MassSleep initializer init

    globals
        private constant integer SPELL_ID = 'A000'
        private constant integer BUFF_ID = 'B000'
        private constant integer DUMMY_ID = 'dumX'
        private constant integer DUMMY_SPELL_ID = 'A001'
        
        private constant string ORDER = "starfall"
        
        // Don't change \\
        
        private integer T
        private constant real L = 0.04
        private constant hashtable H = InitHashtable()
    endglobals
    
    private function range takes integer level returns real
        return 400. + 100. * level
    endfunction
    
    private function duration takes integer level returns real
        return 7. + 2. * level
    endfunction
        
    // Don't change \\
    
    private struct MassSleep
        unit    caster      = null
