I'm really not sure what this plugin does.. If someone can better explain it that would be awesome.

From what i can tell.

Speed glitch on Ladders - Allows you to climb ladders faster than normal.
Incap Glitch - Dead air has a glitch on the truck if you jump down, you become incapped, and will not die.
Water Buffer Glitch - Players lose health under water, heath slowly regenerates to last known value, this doesn't include health buffer value, therefor players can get 199 HEALTH max.

thank you Marcus101RR. Incap Glitch not quite true interpreted - you jump on the incapped survivor while holding USE key this reduces the falling speed.

Installed in my L4D 1 and 2 servs.

Hi,

you should replace

if (buttons & 512 && (8 || 16)) buttons &=~IN_MOVELEFT;
if (buttons & 1024 && (8 || 16)) buttons &=~IN_MOVERIGHT;

by

if (buttons & 512 && (buttons & 8 || buttons & 16)) buttons &=~IN_MOVELEFT;
if (buttons & 1024 && (buttons & 8 || buttons & 16)) buttons &=~IN_MOVERIGHT;

because

(8 || 16)

is not what you want to do (makes you unable to climb using left or right keys in ANY ladder climbing scenario); and (number != 0 || number != 0) will always return true.

Also, to be always using the #defines (IN_FORWARD, IN_MOVELEFT, etc.) would be even better, rather than only sometimes (it seems that you're adressing 2 different things at a time when using a define and its value; i.e. IN_MOVELEFT is 512, so either put 512 or IN_MOVELEFT, not both).

The way I did it :

if ( buttons & IN_FORWARD || buttons & IN_BACK )
{
	if ( buttons & IN_MOVELEFT )
	{
		buttons &= ~IN_MOVELEFT;
	}
	if ( buttons & IN_MOVERIGHT )
	{
		buttons &= ~IN_MOVERIGHT;
	}
}

I also made a plugin using the way you do fast ladder climbing prevention (here). Gave you credit in post.
