Ion Cannon Weapon in Source

This is a port of hjkwe645 aka A.F.'s AMX Mod X weaponmod ion cannon weapon as requested here.

Credits for the math and sounds entirely to him - nice work!

Description:
Players are able to buy ion cannons, charging $10000 by default, by typing !buyion in chat. Now when using the knife outside, you're able to place an ion cannon at your position. Give the satellite time to locate you and see a big laser bashing from the sky destroying anything around.

This should work in any game - I only tested in CS:S though.

If you want to place the ion cannon with a different weapon than the knife change the sm_ion_weapon convar to your weapon.

L4D(2):
Remove the "//" in front of the following line and recompile to use default HL2 sounds instead of the offered sounds, so the clients don't need to download anything.

PHP Code:

//#define ALTERNATIVE_SOUNDS 


Video:
Some more effects have been added since the version in the video.

Admin Command:
There is only 1 command for admins with the root "z" flag:
sm_giveion <#userid|steamid|name> - Give a player an ion cannon.

This command ignores the sm_ion_maxammo setting.

If you set sm_ion_buy_enable 0 and sm_ion_defaultammo 0 in your config file. Only admins with the root flag are able to use the ion cannon.

Compile Requirements:
This plugin uses berni's and Chanz' smlib and exvel's colors library.
Download both and put inside your include folder, if you want to compile yourself.
