I was planning to make a game using it, but the game was not that good so there is only the antihack in it.
Apos' Marine Rush with antihack in it.

I don't understand it. What does it do? What does the EUD read?
What is with this freeze? You create a civ and disable it. What about it?
And then you kill all [any] unit of All Players... doesn't that destroy the game for everyone?

What I decided to do instead of detecting the hack was to detect an action that could only happen when the hack in on. In this map, I decided to detect a selection of a unit the is not supposed to be seen without a hack on.

To make it work, I place a lot of lifted flying buildings (Starport working perfectly in my case) to hide the player from being able to see under them. Once all my buildings are placed, I put a map revealer for player 15 (It will make all buildings placed before it invisible without a map hack.). Usually, it speeds up the map, but since I placed so much buildings, it creates just enough lag so it's almost unnoticeable.

PS1: Basing on my idea, it could be easy to find out more ways to detect other parts of the hack.
PS2: Unit selection is shared, but not the selection of a unit type.

Okay thanks so far, that partly explains the first 2 questions. So you detect If any of the starports gets selected? What if I just draw a selection box? Wouldn't it just select the unit underneath?
Also what do you move the buildings around for? Is it just leftover from your map or does it actually have a use/is it necessary for the anti-hack?

And what about the other questions?

For the moving: For the game I was making, I wanted to create a barrack at each player location, so I stacked a prison cell and moved it so I could move my barrack over the xel naga tower.
For the civilian: I spam disable it since it can crash any hack even Freedom.
The startports are there to hide the minimap so a player that is hacking can't see anything else. As soon as a Starport is selected, game crashes. I guess if I could find an other way to make it crash without having to detect a selection, it could be even better.

Okay I got a fair idea of your anti-hack now. The core is that you found a way to make flying buildings invisible.
It is indeed a good idea but unfortunately limits the map greatly. I couldn't use it in any of my maps as it both prevents air units and detectors.
Thanks for sharing it anyway.

According to all my testings, it didn't make any differences with air units and they are not detectable with detectors (Only hackers can see them).

So you can create air units despite air space filled by these buildings? And air units are not pushed off by them?
That'll be amazing. And not detectable by detectors is also great.

Air units won't get pushed. The only problem with the air units was that you need to set one spot somewhere on the map where there won't be any Starport so that they can be created (If not, it will display an error.).

Sounds interesting, but the lag and unit usage that you describe sound like very significant disadvantages. In addition, if you're depending on the P15 map revealer trick, your map won't be able to be made Mac-compatible, unlike either traditional crashing antihacks or the now-obsolete Mac-friendly EUD antihack developed by Tank_7 (with a little input from myself). I can see certain situations in which your antihack could be worth it, but for me, the downsides are too great to incorporate it into my map.
