[L4D2] Block Pistol Spam
 

About:

If you havent seen this exploit in live action, count yourself lucky. Its a weird/laggy exploit.

The laggy part is because is what the exploit does. What happens is player picks up a melee weapon, finds a pistol and there we. Unlimited pistols.
The player just keep spamming +use upon dropping the melee weapon and getting the pistol in the hand. Somehow this produces an extra pistol.

This equal massive lag as the server is trying to calculate all these falling pistol in the same place.

Now the weird part is not on how this pistol just enters the world. Its more because I noticed that neither item_pickup nor spawner_give_item triggers when pistol gets picked up O.o
So I had to go with player_use and check the entity net class of the entity that is being used. If so block +use for 0.3 seconds.

The following script is completely only for testing purposes. Use with caution!

With this you can do the above explained exploit. Just keep spamming +use once you have a melee weapon and a pistol.

Nice. Thanks.

Is this even necessary any longer given recent game updates?

Re: [L4D2] Block Pistol Spam
 

valve hasn't patched this exploit and it can be used to crash servers, so yes, it's still neccessery.
the exploit dosn't even require a script. if u have a melee and a pistol on floor, just spam E and you'll soon start seeing a hundred pistols :)

Thanks for this plugin, witnessed this by a bunch of.....idjits on my lfd 2 server last night. Luckily I was watching them via HLSW and was able to boot them.

Re: [L4D2] Block Pistol Spam
 

Didn't know about this bug yet, managed to pull it off, but only if you have 2 pistols.

Does L4D2 have the cvar sv_allow_wait_command ?

Re: [L4D2] Block Pistol Spam
 

it does but this exploit dosn't require the script at all. just the use button, a melee weapon and a pistol/magnum.
keep picking the melee and the pistol up once they fall to the ground and there you go. dosn't require the wait script mr zero is talking about.
