[Trigger] Mana consume detection

[TheAyalalalalon]

Hi
I need some help with these triggers i made to detect how much mana a spell is consuming

• Impedido 2
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
  • Actions
    • Set ManaOBJ = (Mana of casting unit)

• Impedido
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
  • Actions
    • Set ManaReal[11] = (ManaOBJ - (Mana of casting unit))
    • Set ManaReal[1] = (ManaReal[1] + ManaReal[11])
    • Floating Text - Create floating text that reads (String(ManaReal[1])) at (Position of casting unit) with Z offset 0.00, using font size 10.00, color (100.00%, 100.00%, 100.00%), and 0.00% transparency

The current issue is that it keeps returning me 0 damage

The Event you're looking for is:

• Unit - A unit Finished casting an ability

You just need to be sure that this spell triggers this event (for instance, Mountain King - Avatar doens't fire this event).

Another approach you can take, is to just put a wait timer and use an array to link the variables you're watching wont change if someone else fires this skill at the same time (I suggest you only take this approach if the ability you're using doens't fires the Finished casting event).

You could use a zero-second timer like below but I can't recall if it was MUI. It's a nice example of the basis of catching the manacost of a spell.

• Mana Detect Cast
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Dark Poison
  • Actions
    • Set Caster = (Triggering unit)
    • Set ManaPrecast = (Mana of Caster)
    • Game - Display to (All players) the text: (Precast Mana: + (String(ManaPrecast)))
    • Countdown Timer - Start Clock as a One-shot timer that will expire in 0.00 seconds

• Mana Detect Timer
  • Events
    • Time - Clock expires
  • Conditions
  • Actions
    • Set ManaPostcast = (Mana of Caster)
    • Game - Display to (All players) the text: (Postcast Mana: + (String(ManaPostcast)))
    • Set ManaDelta = (ManaPrecast - ManaPostcast)
    • Game - Display to (All players) the text: (Mana spent: + (String(ManaDelta)))

After "Starts The Effect" and before "Finishes Casting" there should be the mana consumption, so if you use different triggers, and a variable to keep track of (must be MUI, like maybe using array + unit index), it should work, good.
Dehuna, your method probably won't work correctly when there's some longer "Follow through time" duration.

@IcemanBo Mana is deducted when the "Starts the effect of an ability" event occurs as far as I know, so it'll work no matter how long the cast time is set. Obviously this method won't work on toggle abilities (but does work if it has an initial manacost).

I tested now, printed the mana of <triggering unit> at event "Unit - A unit Starts the effect of an ability", and it printed the mana before consumption.

Sorry, my mistake.

I saw this solution somewhere else here on The Hive but couldn't find the thread. They said that the mana is deducted just after the event (or something like that) and that using a timer with zero duration would be the safest way to detect the difference.
