Cheating Prevention and Detection

03-04-2009, 07:29 PM

There are 3 possible ways that a player can cheat in Sheep Tag.

-Map hacking
-Pauses the game (to causes an interruption in actions)
-Saving the game (to causes same interruption in actions)

Are there way through triggers or 3rd party tools to prevent or detect this events?

I understand that there is a map-hack prevention resource on this sight, but it appears to require that the map has an extra in which will never be revealed to the players. However, I do not want to have this extra area appear on the map. I'd like to keep my minimap fairly clean.

ShadowWolf	Pausing and Saving don't interrupt actions, orders are maintained through these events.

GosuSheep	But they do interrupt a players actions. For example: If I am continuously right clicking, and someone pauses the game, it interrupts my actions, causing a possible mistake. This is why I must prevent or detect these things. If someone pauses the game, waits 0.5 seconds, then resumes the game, a player will be caught off guard; and in a very fast paced game, that can cause a huge problem.

xombie	I've never been caught off-guard like that in a sheep tag, as long as you are paying attention pausing/resuming has no effect on the game play. F10+R+Esc takes less than a second for me to hot-key too, if I feel its been paused for too long. In addition, as ShadowWolf said, it doesn't interrupt orders when the game is paused.

GosuSheep	Ok, let me try again. In world-class sheep tag games, it's a problem. In our world wide tournament, we count it as a 3 minute penalty. To be quite frank, I'm not interested in reasons why I don't need these things. I'm only interested in solutions.

xombie	Pausing - Pause/Resume game 3 times for every player at the beginning of the game, so that they have no more pauses left. Saving - There is no way to disable saving a game. Map Hack - I think PandaMike has some sort of solution to this, you can check the resources section.

Pandamine's solution is the sole best anti-map hacker. You can easily section off a 16x16 (if that!) section of your map for that purpose if its seriously such a big deal to you.

The best you can do about saving is to just plain kick the player; they were cheating anyways. There's an action for when the game is saved; you may be able to get "GetTriggeringPlayer" out of that, I'm not sure.

Xombie's 'cure' for pauses will also work.

xombie	I have a question though. What do you plan to do when someone cheats and lags, causing the game to stop momentarily? Is that cheating too?

Because lagging is unintentional (most of the time), it is not considered cheating. Also, we can use -synclimit 10000 with GHost bots to prevent the lag screen (I wish blizzard would come up with such useful features).

I understand the Pause 3 times method, but with 12 people in a game, that'll take forever... If no one knows of any other prevention then I am SOL on that one.

I have not tried using GetTriggeringPlayer() as a method for handling the save event. The reason for this is that in the UI, the event does not have its conventional "Event - Player saves the game." Because of this, I highly doubt it is possible determine the "Triggering" player. Anyone know a good replay-viewer tool to check for saves?

Thanks for the suggestion of PandaMine's anti-map hack. I will investigate and implement.

Do this test:

* open a melee map with Jass New Gen Pack
* Create a trigger called "test"
* Convert to custom text
* select the code and erase it
* paste this code:

JASS:

scope Test initializer init

private function Show takes nothing returns nothing
    call DisplayTimedTextFromPlayer(GetTriggerPlayer(), 0,0,2, GetPlayerName(GetTriggerPlayer()) + " has saved the game...")
endfunction

private function init takes nothing returns nothing
    local trigger t = CreateTrigger()
    call TriggerRegisterGameEvent(t, EVENT_GAME_SAVE)
    call TriggerAddAction(t, function Show)
    set t = null
endfunction

endscope

* Save it with other name
* Test it on Bnet

if it gives the name of the player then you can detect the moron who fucks your game :)

emjlr3	"world class" tournaments over bnet are lame anyway play in person, over lan, and ppl who are fags can be dq'd

GosuSheep	Thanks for the extremely useful suggestion emjlr3. You want to pay for 20 European's plain tickets? Moyack, I will try your script. If it works, I will add rep to you. I have been looking for a solution for ages. Vexorian couldn't even find one.

JASS:

scope Test initializer init

private function Show takes nothing returns nothing
    call DisplayTimedTextFromPlayer(GetTriggerPlayer(), 0,0,2,"%s has saved the game.")
endfunction

private function init takes nothing returns nothing
    local trigger t = CreateTrigger()
    call TriggerRegisterGameEvent(t, EVENT_GAME_SAVE)
    call TriggerAddAction(t, function Show)
    set t = null
endfunction

endscope

ps learn "secrets" of jass.

darkwulfv	Does that actually detect the player? Eg; does EVENT_GAME_SAVE track the player who saved, or just detect the action of the game saving?
