Snippet making a generic unit event for: unit takes damage

[LoveTD's]

I've seen lots of people asking this so I decided to post it in here

Damage Taken 1
    Events
        Unit - A unit Is attacked
    Conditions
    Actions
        Trigger - Add to Damage Taken 2 <gen> the event (Unit - (Triggering unit) Takes damage)

this means that Damage taken 2 has the event: a unit takes damage
and you can refer to that by using triggering unit (not attacked unit just a sec :S attacking unit did seem to work so maybe attacked unit too ^^ try it out if you want to )

Ahm... one massive flaw with this.

What if I attack the same unit 10 times? I'm adding 10 events, and 9 of those aren't needed at all.
If the Takes Damage event fires, I'm doing the same stuff 10 times for the same unit.

hmm your right didn't notice because it did work in my case :S maybe I should make some kind of variable that makes sure the triggering unit is added to the event only once :S

Damage detection init 1
    Events
        Map initialization
    Conditions
    Actions
        Set TempGroupA = (Units in (Playable map area))
        Unit Group - Pick every unit in TempGroupA and do (Actions)
            Loop - Actions
                Unit - Add Damage detection spellbook  to (Picked unit)
                Trigger - Add to All damage <gen> the event (Unit - (Picked unit) Takes damage)
                Trigger - Add to Physical damage <gen> the event (Unit - (Picked unit) Takes damage)
                Trigger - Add to Spell damage <gen> the event (Unit - (Picked unit) Takes damage)


-----------------------------------------------------

Damage detection init 2
    Events
        Unit - A unit enters (Playable map area)
    Conditions
    Actions
        Unit Group - Add (Triggering unit) to TempGroupB
        Unit Group - Remove all units of TempGroupA from TempGroupB
        Unit Group - Pick every unit in TempGroupB and do (Actions)
            Loop - Actions
                Unit - Add Damage detection spellbook  to (Picked unit)
                Trigger - Add to All damage <gen> the event (Unit - (Picked unit) Takes damage)
                Trigger - Add to Physical damage <gen> the event (Unit - (Picked unit) Takes damage)
                Trigger - Add to Spell damage <gen> the event (Unit - (Picked unit) Takes damage)
                Unit Group - Add (Picked unit) to TempGroupA
                Unit Group - Remove (Picked unit) from TempGroupB

That's the code I used for my DD initialization. It'll prevent duplicate events from being registered

In JASS, it is easy to add and remove events and conditions.
And this isn't a snippet, it's a hint.

sry didn't find the hint section

                Unit Group - Add (Picked unit) to TempGroupA
                Unit Group - Remove (Picked unit) from TempGroupB

thanks a lot for that code! b.t.w. 3 different damage types? wherefor and how? And I don't see what the use is of a damage detection spellbook :S can you explain it to me?

Well, this isn't JASS, is it? Anyway, JASS damage detection systems are stupidly difficult to use for GUI users. Most of the ones I've seen use various things that make it almost completely unusuable in GUI (I'm sure that one can be made to cater for GUI, but who's gonna do it?) such as structs, creating new triggers internally, and what-not

And this isn't a snippet, it's a hint.

Dictionary.com says otherwise

a little piece, especially of information

From the looks of it, this is little, and it's a piece of information, so it would qualify as a snippet ^^
