[Spell] Summon unit, drain mana over time trigger.

[Midasowski]

(First, sorry for my english)
Hi, i need a help with creating spell, im not the best in making triggers so this is why im posting this thread.
So i have a unit with a spell "Summon Wolf" it drains mana over time, until 0, then summoned unit disappears. Caster is a normal mage unit, like Necromancer or Banshe, so there can be many Wolfs in the same time, but 1 caster can have only one wolf. If caster dies, the wolf will also die. And of course if wolf dies the mana will stop draining.

Can someone help me, and create this spell? I would be very grateful.

You should check how to make a spell MUI. I cant send links cuz im on phone.

The main thing you should focus is;

1)Create the wolf where you want when the spell is cast.
2)Start a loop to trigger mana draining.
3)In the loop, check if the caster is alive and if the wolf is alive. If one of these conditions are met stop the loop.

You can also use a custom Immolation ability to continually drain your mana, that way you will also have control whether to summon or unsummon the wolf, and you can have only one for each unit. It works with one unit, but I'm not sure about how to make it MUI, though...

Easiest solution would be adding in a unit indexer. Save the caster and wolf in separate unit arrays using each other's index as the array index. then you have 4 events you must detect:

1. Immolate is cast (you might have to detect it by the immolate (could be immolateon) order, not spell cast event):
   
   create Wolf
   set Mage_Unit[index of created wolf] = caster
   set Wolf_Unit[index of caster] = created wolf
2. Caster type unit dies, kill Wolf_Unit[index of caster]
3. Wolf type unit dies, order Caster_Unit[index of dying wolf] to immolateoff (maybe unimmolate honestly I don't remember)
4. Unit is ordered to immolateoff, if it has an associated wolf then remove it.

Might need to do some extra things if Resurrection exists in the map. One could kill the wolf (to stop the mana drain) and then revive it, unless the wolf is set to not be resurrectable in the object editor.
