Spell Critters of the world, Unite!

[WolSHaman]

Targeted channeled ability.
Difficulty to import: medium-hard
GUI or JASS: GUI
MUI: Can have up to 500 units casting at once.
Thanks to Flare for his GUI-MUI tutorial, it really helped!

Description: The critter lord summons wave after wave of exploding suicidal critters to attack the targeted enemy. Each critter deals 30 damage per level of the ability.

Note: According to some other people who saw this spell, I have learned that some young and foolish minds believe that this spell could possibly be construed as bloody and/or gory. If this offends you, I suggest you not play the map.

How to import:
1- First, import all of the variables exactly as they appear in the variable editor, except for allplayers, the player group one, you don't need to import that one, I just used it so that you could see the whole map.
2- go to the object editor and go to the abilities tab. copy the ability from their and paste it into your map, then copy and paste all the units from this map into the map you want the spell in.
3- copy and paste all the triggers from this map into the map you want them in, importing the triggers titled "melee initialization" and "aasb" last, import all the other triggers first. Now, here's the triggers used in this map:
detect damage triggers (add these two triggers only after you've imported the other triggers):

initialization

Melee Initialization
    Events
        Map initialization
    Conditions
    Actions
        Set startingunits = (Units in (Playable map area))
        Unit Group - Pick every unit in startingunits and do (Actions)
            Loop - Actions
                Trigger - Add to explode suiciders <gen> the event (Unit - (Picked unit) Takes damage)
        Custom script: call DestroyGroup (udg_startingunits)
        Set allplayers = (All players)
        Set suicidetype[1] = Suicidal Chicken
        Set suicidetype[2] = Suicidal Frog
        Set suicidetype[3] = Suicidal Rabbit
        Set suicidetype[4] = Suicidal Rat
        Set suicidetype[5] = Suicidal Sheep

detecting units after initialization

aasb
    Events
        Unit - A unit enters (Playable map area)
    Conditions
    Actions
        Trigger - Add to explode suiciders <gen> the event (Unit - (Triggering unit) Takes damage)

Next, we need the triggers to determine the caster and target, and to spawn the critters periodically:

determining the caster and the target

Set caster and stuff
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to Critters of the World, unite! 
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                customvalue Greater than or equal to 500
            Then - Actions
                Set customvalue = 1
            Else - Actions
                Set customvalue = (customvalue + 1)
        Unit Group - Add (Triggering unit) to creepunitecasters
        Unit Group - Add (Target unit of ability being cast) to creepunitevictims
        Set caster[customvalue] = (Triggering unit)
        Set target[customvalue] = (Target unit of ability being cast)

removing the caster and target when the unit stops casting

stop casting
    Events
        Unit - A unit Stops casting an ability
        Unit - A unit Finishes casting an ability
    Conditions
        (Ability being cast) Equal to Critters of the World, unite! 
    Actions
        Unit Group - Remove (Triggering unit) from creepunitecasters
        Unit Group - Remove (Target unit of ability being cast) from creepunitevictims

removing the target when the target dies

stop casting 2
    Events
        Unit - A unit Dies
    Conditions
    Actions
        Unit Group - Remove (Triggering unit) from creepunitevictims

Lastly, we need the trigger that periodically spawns the suicidal critters and causes them to damage the enemy.

Spoiler

the periodic spawning

periodic attack
    Events
        Time - Every 0.50 seconds of game time
    Conditions
    Actions
        For each (Integer A) from 1 to 500, do (Actions)
            Loop - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        (caster[(Integer A)] is in creepunitecasters) Equal to True
                        (target[(Integer A)] is in creepunitevictims) Equal to True
                        (target[(Integer A)] is alive) Equal to True
                        (caster[(Integer A)] is alive) Equal to True
                    Then - Actions
                        Set temp_point = ((Position of target[(Integer A)]) offset by (Random real number between 300.00 and 800.00) towards (Random real number between 0.00 and 359.99) degrees)
                        Unit - Create 1 suicidetype[(Random integer number between 1 and 5)] for (Owner of caster[(Integer A)]) at temp_point facing Default building facing degrees
                        Unit - Set the custom value of (Last created unit) to (Integer A)
                        Unit - Order (Last created unit) to Attack target[(Integer A)]
                        Unit - Add a 3.00 second Generic expiration timer to (Last created unit)
                        Custom script: call RemoveLocation (udg_temp_point)
                    Else - Actions

the damaging note- the events for this trigger were added in the detect damage triggers, so you don't need to worry about that

explode suiciders
    Events
    Conditions
        Or - Any (Conditions) are true
            Conditions
                (Unit-type of (Damage source)) Equal to Suicidal Chicken
                (Unit-type of (Damage source)) Equal to Suicidal Frog
                (Unit-type of (Damage source)) Equal to Suicidal Rabbit
                (Unit-type of (Damage source)) Equal to Suicidal Rat
                (Unit-type of (Damage source)) Equal to Suicidal Sheep
    Actions
        Unit - Cause caster[(Custom value of (Damage source))] to damage target[(Custom value of (Damage source))], dealing (30.00 x (Real((Level of Critters of the World, unite!  for caster[(Custom value of (Damage source))])))) damage of attack type Spells and damage type Normal
        Unit - Explode (Damage source)

note to foodflare: if you read this and think "hey, Crazed_Hobo made this wtf, keep in mind that I am Crazed_Hobo, I just use this Alias on thehelper.
Anyways, enjoy the spell!

For the summoning part, actually you can shorten the code greatly by storing every Suicidal unit type into variables, then spawn them randomly, like :

Set SuicidalType[1] = Suicidal Chicken
Set SuicidalType[2] = Suicidal Rat
Set SuicidalType[3] = Suicidal Frog
etc.

Unit - Create 1 SuicidalType[Random integer between 1 to 3] and so on....

Makes sense, good call!
