Need Help (1 custom spell)

[Jinxx]

Hey guys, I've got a spell I need to implement, and I know how it should (theoretically) work, but I'm confused as to how I should set it up in JASS (I'd prefer JASS, but vJASS would be ok as well I guess)...

Essence Flux: "Target a location on the ground with malefic energy - all hostile heroes within 500 AoE will be slowed by N% for the duration of the spell (10 seconds), as well as lose Z% of their total mana over time (this mana is stolen by the caster)."

Level 1: Enemy heroes lose a total of 1% of their mana, and have their movement speed slowed by 4%.
Level 2: Enemy heroes lose a total of 2% of their mana, and have their movement speed slowed by 8%.
Level 3: Enemy heroes lose a total of 3% of their mana, and have their movement speed slowed by 12%.
Level 4: Enemy heroes lose a total of 4% of their mana, and have their movement speed slowed by 16%.
Level 5: Enemy heroes lose a total of 5% of their mana, and have their movement speed slowed by 20%.

So what this basically does is target all hostile heroes within the AoE (spell is ranged, has a circular reticule), smacks them with a temporary movespeed slow (dummy pops in and casts it), and bleeds their mana (which the casting hero then receives).

The trouble I'm having with is setting up the mana leak. I would guess it needs some kind of periodic timer or somesuch? Also, how do I make it so that a unique timer runs for each enemy hero caught by the spell (since the caster steals mana from multiple enemy heroes caught in the AoE)?

Thanks for any help. :shades:

you can do this in gui:

here you detect the cast and add the units to a unit group that sucks mana every 0.2 seconds (to make it smooth rather than a chunk of mana every second)

• Mana Leak Cast
  • Events
    • A unit Casts an ability targetting a point
  • Conditions
    • Ability cast is equal to (your ability)
  • Actions
    • Set Temp_Point = Target Point of ability cast
    • Set Temp_Group[1] = Units in playable map area matching conditions ((Matching Unit is in Temp_Group[1] is equal to true) Or ((Owner of Matching unit is an enemy of Owner of Casting Unit) And (Matching Unit is within (range) of Temp_Point)))
    • Set Temp_Group[2] = Units within (range) of Temp_Point matching conditions (Owner of matching unit is an enemy of the owner of Casting unit)
    • Unit Group - Pick Every unit in Temp_Group[2] and do actions
      • Loop Actions
        • Hashtable - Save Real 10.00 as (key Picked Unit) of 1 in Last Created Hashtable (create one at map init)
        • Hashtable - Save Real (Greatest Between Real(Level of (ability) for casting unit)/50 and Load Real (key Picked Unit) of 2 in last created hashtable) as (Key Picked Unit) of 2 in last created hashtable
    • Custom Script: call RemoveLocation(udg_Temp_Point)
    • Custom Script: call DestroyGroup(udg_Temp_Group[2])
    • Trigger - Turn on Mana Leak <gen>

This is the Trigger that takes the mana

• Mana Leak
  • Events
    • Periodic Event - Every 0.2 seconds
  • Conditions
  • Actions
    • Set Temp_Group[2] = Units in Temp_Group[1]
    • Unit Group - Pick Every Unit in Temp_Group[2] and do actions
      • Unit - Set Mana of picked unit = Mana of Picked Unit - (Load Real (Key Picked Unit) of 2 in last created hashtable)
      • Hashtable - Save Real ((Load Real (key Picked Unit) of 1 in last created hashtable) - 0.2) as (Key Picked Unit) of 1 in last created hashtable)
      • If Then Else
        • If
          • (Load Real (key Picked Unit) of 1 in last created hashtable) is equal to 0.00
        • Then
          • Unit Group - Remove Picked Unit from Temp_Group[1]
          • If Then Else
            • If
              • (Number of Units in Temp_Group[1]) is equal to 0
            • Then
              • Custom Script: call DestroyGroup(udg_Temp_Group[1])
              • Trigger - Turn off this trigger
            • Else
        • Else
    • Custom Script: call DestroyGroup(udg_Temp_Group[2])
