[Trigger] Position Comparison

[Null]

I want to make a Paladin automated. The biggest problem I ran into is the Holy Light. I want to make that if the paladin is close to the attacked low HP unit, he will heal the unit.
Pls show me the position comparison trigger.(If paladin is close enough to cast the spell and the unit is under 20% hp) Thanks!!!

This is very simple.. unless you want to use the melee ai system rather than triggers. Should specify.

• Events
  • Generic unit event - A unit is attacked
• Conditions
  • Real comparison - Health percentage of (Event Response - Attacked unit) is less or equal to 20
• Actions
  • Set TempPoint1 = Position of Paladin
  • Set TempPoint2 = Position of (Attacked unit)
  • If (Real comparison - Distanse between TempPoint1 and TempPoint2 is less than 600) Order Paladin to Human Paladin - Holy Light (Attacked unit) else Do nothing
  • Custom script: call RemoveLocation(udg_TempPoint1)
  • Custom script: call RemoveLocation(udg_TempPoint2)

The paladin isn't a defined unit.

Then you'll have to pick every unit around the attacked unit and check if picked unit is equal to a Paladin. Then I'll pick a random unit from that unit group and heal the attacked unit. In fact I do this in one of my own triggers:

• Druid of the Claw Rejuvenation
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • ((Triggering unit) has buff Rejuvenation) Equal to False
    • (Percentage life of (Triggering unit)) Less than or equal to 20.00
  • Actions
    • Set VariableSet Point = (Position of (Triggering unit))
    • Set VariableSet UnitGroup = (Units within 400.00 of Point matching (((Unit-type of (Matching unit)) Equal to Druid of the Claw (Night Elf Form)) and (((Matching unit) belongs to an enemy of (Owner of (Triggering unit)).) Equal to False)).)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in UnitGroup) Greater than 0
      • Then - Actions
        • Set VariableSet Unit = (Random unit from UnitGroup)
        • Unit - Order Unit to Night Elf Druid Of The Claw - Rejuvenation (Triggering unit)
      • Else - Actions
    • Custom script: RemoveLocation(udg_Point)
    • Custom script: DestroyGroup(udg_UnitGroup)

In your case you'd want to replace the Druid with the Paladin and Rejuvenation with Holy Light.
(I just added the 20% health condition to match your case)

NOTE: be aware that I use Lua in my custom scripts, so if you're on JASS need to replace those with this:

• Custom script: call RemoveLocation(udg_Point)
• Custom script: call DestroyGroup(udg_UnitGroup)

Why not use a loop instead? surely a paladin should heal any unit when found, not just when attacking.

every 0.03 seconds

pick all units of type paladin

set p = picked unit
pick all units within 400 of p

if % health of picked unit is lower than 20%

order p to cast holy light on picked unit

​

Would also need to check if found unit is an ally and so on, but this is the short version

The last 2 ones must include the variables, right?

Custom script: RemoveLocation(udg_Point)
Custom script: DestroyGroup(udg_UnitGroup)

Yes you need those. To get rid of leaks in your map you need to destroy points and groups.

 

[Null]

My Point variable is called: HealingPoint and my UnitGroup Variable is HealingGroup. How should I make them? When I replace Point with HealingPoint is fails to save. Same with the group.

Nvm. Forgot to put the 'call' part. X)
Thank you very much! and thank you Chaosy too!
