Triggering a spell

[Dispatcher]

Can somebody tell me how to trigger a hero to siphon mana a unit or a hero when its mana pool is below 400?

Is it for a specific unit or generic ? If it's the first then you can do this :

• Siphon Mana
  • Events
    • Unit - Blood Mage 0000 <gen>'s mana becomes Less than 400.00
  • Conditions
  • Actions
    • Set Point = (Position of (Triggering unit))
    • Unit - Order (Triggering unit) to Human Blood Mage - Siphon Mana (Random unit from (Units within 600.00 of Point matching ((Mana of (Matching unit)) Greater than 0.00)))
    • Custom script: call RemoveLocation (udg_Point)

If it's the latter, then remove the event on the above trigger and do this at Map Initialization :

• Unit Group - Pick every unit in (Units in (Playable map area)) and do (Trigger - Add to Siphon Mana <gen> the event (Unit - (Picked unit)'s mana becomes Less than 400.00))

Just take care of memory leaks at the point where the unit is told to siphon Mana a target.

Thank you so much guys and can i have one more request? How do you trigger a hero with a starfall ability to use its ability if thier are more than 6 units? Unfortunately my hero uses the starfall ability when there is an enemy hero so i want my hero to use starfall even if there are no enemy heroe's.

It will take at least 2 triggers to produce the intended effect.

First trigger: (Logic flow)
Event: Every <period> seconds of game-time
Actions:
Pick all units in <container group> and do the following:
Set <enemy count> to 0
Enumerate units within range of picked unit.
Pick all units in <enumerated group> and do the following:
(Check if picked unit is alive and an enemy)
If (Condition is true) then
Add 1 to <enemy count>
Endif
(Check if enemy count is greater than or equal to 6)
If (Condition) then
Order picked unit to Starfall
Endif

Second trigger:
Actions
Add desired unit to the <container group>

Okay a little bit confusing can you just embed the trigger here? I only rely on embeded triggers to fully understand the triggers and also does this trigger need to have a variable?

Alright. Here's the first trigger: (Both triggers require variables and first trigger is not optimized yet to remove memory leaks)

• Events
  • Game: Every <period> seconds of game-time
• Conditions
• Actions
  • Unit Group - Pick all units in <container group> and do (Loop - Actions)
    • Loop - Actions
      • Set <enemy count> = 0
      • Set <temp unit> = (Picked unit)
      • Unit Group - Pick all units in (units in <desired range> range of (Position of <temp unit>) and do (Loop - Actions)
        • Loop - Actions
          • If (All Conditions are True) then do (Then - Actions) else do (Else - Actions)
            • If - Conditions
              • (Picked unit) is alive Equal to True
              • (Picked unit) belongs to an enemy of (Owner of <temp unit>) Equal to true
            • Then - Actions
              • Set <enemy count> = <enemy count> + 1
            • Else - Actions
      • If (All Conditions are True) then do (Then - Actions) else do (Else - Actions)
        • If - Conditions
          • <enemy count> Greater than or Equal to 6
        • Then - Actions
          • Unit - Order <temp unit> to Night Elf Priestess of the Moon - Starfall
        • Else - Actions

The second trigger

• Events
• Conditions
• Actions
  • Unit Group - Add <desired unit> to <container group>

The second trigger

• Events
• Conditions
• Actions
  • Unit Group - Add <desired unit> to <container group>

Thank you so much you have helped me alot and can i ask what's the use of the second trigger and why is it separated from the other trigger? And also as i have asked before does this trigger have a variable if thier are can you tell me what type of variable they are thanks! (Sorry for keep asking questions i just really wanna make sure that i have understood this trigger)

The second trigger is for adding a desired unit (who can cast Starfall) into the container group. The second trigger is a plain trigger which adds a desired unit. Due to the ambiguity of the desired unit, I have left it as is.

The two triggers presented require variables.
<container group> is a unit group variable.
<enemy count> is an integer.
<temp unit> is a unit.

Thank you so much for your help! Now my AI Heroes will be much more usefull.

Well okay sorry for the late reply but the Enemy count (Integer) does not appear in If conditions - (Enemy count) greater than equal to 6 only the temp unit variable why is this?

Is it alright if you post the problematic trigger?
