/* Updated Throwing Knives by -]ToC[-Bludy
*
*
* COMMANDS: throw_knife - This is the command for everyone to throw knives
* say /knifehelp - Brings up knifehelp menu to help players bind keys
* say /throwingknives - Same as /knifehelp
*
* CVARS: amx_throwknives (default 0) Toggles Throwing Knives on and off ( 1 or 0 )
* amx_knifeammo (default 5) The amount of ammo to be given at roundstart ( 1 or higher )
* amx_knifetossforce (default 1200) Force at which knives are thrown ( 200 or higher )
* amx_maxknifeammo (default 10) Maximum amount of knives allowed at once ( 1 or higher )
* amx_knifedmg (default 25) Damage dealt on a knife hit ( 1 or higher )
* amx_dropknives (default 1) Toggles knife dropping on death on and off ( 1 or 0 )
*
* DROPPED FEATURES:
*
* - You must bind a key to throw_knife, USE + ATTACK was removed due to excess lag that likely does more harm than good
* - You can no longer drop your knives on command, only when you die
* - Team Attack system dropped, I am leaving your server admins in charge of punishment
*
* NEW FEATURES:
*
* - New knife model, more effecient, smaller file size, easier to download
* - New contact system, knife will stick to whatever they hit
* - New code which is less CPU intensive, less bugs, server crashing seems to be eliminated.
*
* DESCRIPTION:
*
* It was brought to my attention a few days ago that with the update to the AMX forums the file attached to the bottom
* of the forum topic had only an .amx file and no custom model. This gave me the motivation to create a new model that
* was smaller and faster to download, and a brand new knife system to make the knives more realistic. It took a few
* server crashes to get the code right, but it payed off in the end. A few of my clan members and I played throwing
* knife darts on one of the players sprays to celebrate.
*
* The knives work a lot better than before, and they are a lot of fun to play with. So get your knives out
* and go Have Fun
*
