Victory by destroying all buildings

[EivindL]

How can I do it so that I win when I destroy all of the enemy player's buildings without using the melee trigger? I checked the second WoL mission, because I know that's such a mission, but I drowned in my own confusion of the triggers.

There is a "check if a player's buildings are destroyed" trigger, where there's a condition that says:

(Number of Living units in (Any units in Anywhere owned by player PLAYER_01_USER matching Required: Prevent Defeat, with at most Any Amount)) == 0

I understand that trigger... almost. How does the editor know "Prevent Defeat" is buildings? Or to ask differently, can someone explain all this to me? I'm sure it's very simple, but I'm getting confused.

There's actually a flag in the data editor for units that is called "Prevent Defeat".

Blizzard generally uses this so that buildings will prevent you from losing as long as you have them.

However, the reason for using this and not a simple "is building" check is because some things that are technically buildings, such as creep tumors, do not prevent you from losing (ie, if you have 1 creep tumor you lose, but 1 pylon you don't.)

So if I copy that trigger and apply it to the enemy, I will win when I destroy all his buildings?

Alternatively, if I wanted a unit or a creep tumor to be destroyed in order to win, I simply flag them as "prevent defeat"?
