The function CalculateSGHitPellets is for calculating the hit pellets of a Sawn-Off shotgun or a Pump Action shotgun.

The function CalculateCSGHitPellets is for calculating the hit pellets of a Combat shotgun.

The functions should only be called if the weaponid is the correct one for each. (Combat Shotgun: 27, Sawn-Off: 26, Pump Action: 25)

Both functions behave the same way.
They must receive the parameter "amount" from your OnPlayerGiveDamage callback in order to return the amount of hit pellets.
I.E. Call from the callback as CalculateSGHitPellets(amount);

They can optionally receive a second parameter to return a percentage of hit pellets instead of amount of hits pellets.
I.E. Call from the callback as CalculateSGHitPellets(amount, 1);

	} 
	else{
		new missedPellets = floatround(missedDamage / 3.30);
		missedPellets = 15 - missedPellets;
		if (percentage == 0) return missedPellets;
		else return (missedPellets * 100) / 15;
	}
}


stock CalculateCSGHitPellets(Float:amount, percentage=0){
	new Float:missedDamage = 39.60 - amount;
	if (missedDamage == 0){
		if (percentage == 0) return 8;
		else return 100;
	} 
	else{
		new missedPellets = floatround(missedDamage / 4.95);
		missedPellets = 8 - missedPellets;
		if (percentage == 0) return missedPellets;
		else return (missedPellets * 100) / 8;
	}
}

An important bit after being reached about this: As can be observed on the code, the resulting percentages or pellet counts are a function of the damage reported. This will not work if your server does weapon damage changing, be it by memory hacking or any other method! Not without changing 3.30 (sg & sawsg damage) and 4.95 (spas) to the damages your script uses at least.
