[Trigger] Delete all creeps from one player, except building

[Wolf_Guard]

Well, just recently, I've decided to become the newest editor of a really old map that I used to enjoy a few years ago on WC3. Every time I hosted it, or joined someone else's version of this game, there would be a full-house within a few minutes... That's how good it was. I want to bring this map back, so people can experience and make a lot of good memories from this map, just like I have...

Jesse told me to post here, so he can better help and explain with my current situation. This map gets flooded with creeps very easily if there are too little players. I want to prevent that by having Red type -clearcreeps, so that the creeps will all be deleted off of the map. However, I do not want neutral-hostile's buildings deleted.

I already know where to begin with this. I just don't know what to put under 'Actions'. :X If you could explain it in great detail, I will worship the ground you walk on. It has been a couple years since I've messed with the World Editor to a real good extent.

The crudest version would be to use "Pick all units matching Condition" with the required conditions, then removing those units. However, this will leak, but you should look up leaks anyways to get rid of other leaks you may come across.

Alright, thank you for letting me know.

Edit: I think I'm not thinking right. :/ Can't seem to set this trigger up correctly.

I had gotten tired of staying awake and decided to just delete the trigger and restart fresh when I woke up. Right now, here is my current trigger that I am building from:

Events:
Player - Player 1 (Red) types a chat message containing -clearcreeps as An exact match

Conditions:
((Picked Unit) is A ground unit) Equal to True

Actions:
---- NO ACTIONS YET ----

However, I just noticed the trigger that removes a player's units when they leave uses a similar action, so I'm going to try to base the action off of that one before I do anything else. (also, two different computers I use to surf the web and play games on... Sorry. :/)

EDIT: Trigger works after basing it off of the Player Leaves trigger. Thank you for your advice/help, Tonex.

Post up your final trigger anyways and we can assess it and let you know if there is any problems with it you might encounter later. :]

[Tonex]

Yeah, make sure to look up leaks.

It's basically what Tonex said, but I finally understood because I had gotten sleep. Before I had gotten sleep, I was deprived of it for about a day, so I wasn't at my best. Anyway, I've just made my first protected version (and yes, I've backed up the non-protected one, don't want a little mishap to happen... xD).

Here's the trigger:

Events:
Player - Player 1 (Red) types a chat message containing -clearcreeps as An exact match

Conditions:
---- NO CONDITIONS ----

Actions:
Unit Group - Pick every unit in (Units owned by Neutral Hostile) matching (((Picked unit) is A structure) Equal to False)) and do (Unit - Remove (Picked unit) from the game)

So yes, basically what Tonex told me to do.

That trigger contains memory leaks and will contribute to an unstable map. You should really look up memory leaks and how to fix them, blizzard did a bad job with the tools they gave us.
