Smoke Grenade Features (anti 16bit)

/**
*
* Smoke Grenade Features
* by Numb
*
*
* Description:
* This plugin fixes some smoke grenade related bugs:
* + Ability to see through smoke.
* + Ability to see through smoke even better if using 16 bit.
* + Smoke grenades do not explode in air.
* + Smoke can go through walls.
* + Smoke grenades can and do lag up many players (fps drops).
*
*
* Requires:
* FakeMeta
* HamSandWich
*
*
* Additional Info:
* + Tested in Counter-Strike 1.6 with amxmodx 1.8.1 (with and without 16 bit).
*
*
* ChangeLog:
*
* + 1.4
* - Changed: Improved cheat protection.
* - Changed: Smoke disappears 10 seconds faster (now it's 35 seconds and value can be changed in source code config).
*
* + 1.3
* - Fixed: Damaged archives - no need to download sprites.
* - Added: Ability to see through smoke even better when standing inside of it (can be changed in source code config).
* - Added: Ability to make certain percentage of smoke to be black. Supports only original version "sgren_features".
*
* + 1.2
* - Fixed: svc_bad errors.
*
* + 1.1
* - Fixed: Smoke is more dense (harder to see through it where it ends).
* - Fixed: Easier to see through smoke when you are standing inside of it.
*
* + 1.0
* - First release.

// ========================================================================= CONFIG START =========================================================================

// Radius in units from smoke grenade where smoke can be created. Float number type is needed
#define SMOKE_MAX_RADIUS 200.0 // default: (200.0)

// Number of smoke puffs what will be created every 0.1sec from one grenade (the higher this value is - the higher is ability of getting svc_bad errors)
#define SMOKE_PUFFS_PER_THINK 5 // default: (5)

// How long smoke will stay on until it disappears (in seconds). NOTE: Counter-Strike default is 25.0
#define SMOKE_LIFE_TIME 35.0 // default (35.0)

// How much percent of the smoke will be black? (NOTE: Using this feature can make smoke to go throw roof)
#define SMOKE_BLACK_PERCENT 0 // default: (0)

// Ability to see throw smoke better when standing inside of it (one of ???) (setting it to 0 will remove this feature)
#define VIEW_ABILITY 3 // default: (3)
