How can I write a trigger to detect when a terran building burns to its death? (Starcraft 2)

Question

I'm working with Starcraft 2 Map Editor, and am having a little bit of a trigger problem.

It's quite easy to detect when a specific unit kills a structure (simply check if triggering unit == whatever) but I'm not quite sure how to tell when a building dies to to either fire (terran buildings) or bleeding out (zerg buildings when off creep).

What condition should I be looking for in my "a unit dies" trigger to see if one of those two situations occured?

PS: Sorry for lack of available tags!

Answer 1

There is a behavior for Terran buildings that applies the burning effect periodically if the building's health is below 1/3. To see if a building is killed by this effect, you could do this:

Events
    Unit - Any Unit takes Fatal Any damage (from Any effects)
Local Variables
Conditions
    (Damaging effect) == BurndownDamage (Unnamed)
    (Unit type of (Triggering unit)) == <building>

Edit: I forgot the zerg building part, but it's exactly the same but with a different effect:

    (Damaging effect) == ZergBuildingNotOnCreepDamage (Unnamed)

Answer 2

I've been poking around. I've determined that every terran building has an effect "Terran Burn Down" or some such, that I assume is what is actually causing the damage.

I'm not sure of the specifics, exactly, but I imagine one of two things should be possible:

• The building counts as its own killer (because its death is related to an effect it 'owns')
• The death can be tracked by attributing it to the effect, something along the lines of "Unit dies" Condition: Killing Effect == Terran Burn Down.

I imagine the zerg buildings have a similar 'requires creep' ability.

I'll keep investigating and keep this open in case someone can provide a fuller answer.
