How to detect units dealing damage?

[Ramza]

I need this for a spell, which fires back whenever a unit gets damaged.

I got the spell working, but the trigger is just huge. Because I got to think of all the different ranged units, with different missle speeds, etc.

So, is there a way to detect when a unit is losing life, and what unit is dealing the damage?

Use Hmmm Damage Detection System.

 

[Pharaoh_]

• Trigger
• Events
  • Map Initialization
• Conditions
• Actions
  • Custom script: set bj_wantDestroyGroup = true
  • Unit Group - Pick every unit in (Units in (Playable Map Area)) and do (Actions)
    • Loop - Actions
      • Trigger - Add to Trigger2 the event (Unit - (Picked unit) takes damage)

• Trigger1
• Events
  • Unit - A unit enters (Playable Map Area)
• Conditions
• Actions
  • Trigger - Add to Trigger2 the event (Unit - (Triggering unit) takes damage)

• Trigger2
• Events
• Conditions
  • (Level of Fireback for (Triggering unit)) Greater than 0
• Actions
  • Unit - Cause (Triggering unit) to damage (Damage source), dealing 100.00 damage of Attack type Spells and Damage type Normal

So, actually, what cboy123 said, but ala-triggered.

Thanks!
I was stuck at this spell for a pretty long time.

Alternative:

• Trigger
• Events
  • Unit - A unit learns a skill
• Conditions
  • (Hero Learned Skill) Equal to Fireback
  • (Level of Fireback for (Triggering unit)) Equal to 1
• Actions
  • Trigger - Add to Trigger2 <gen> the event (Unit - (Triggering unit) takes damage)

• Trigger2
• Events
• Conditions
• Actions
  • Unit - Cause (Triggering unit) to damage (Damage source), dealing 100.00 damage of Attack type Spells and Damage type Normal

This method is highly recommended than the previous one. This method will make less checks in-game.

Ah, yeah. No unit groups now.

 

[Ramza]

One thing though. Each time the hero levels up this ability, the trigger will add the same event. Is that not a problem?

Edit: Never mind. Solved that.

I had already added a condition to prevent that from happening:

• (Level of Fireback for (Triggering unit)) Equal to 1

How did I not see that? :I

Great stuff, that trigger. Not just for this spell, but in general.

I dislike GUI detections but if it is for heroes only meehh it won't matter but if you've used the first example pharaoh showed it would be a total mess compared to vJASS and JASS systems.

 

[Ramza]

No problem here though. It's for one hero only.

And my spell is based on his second example.
