Step 1
This tutorial will teach you how to turn the nailgun into a gatling gun ala doom. First, you need to open weapons.qc and go until line "void() player_nail1; and write this: 

void()      player_gat1;  // gatling gun firing (see later)
Step 2
Now, further in weapons.qc, find the line: .float hit_z; . Above it, add this:

void(float ox, float ox2) W_FireGatSpikes =  // this is a slightly modified version of firespikes
{
	local vector	dir;
	local entity	old;
	
	makevectors (self.v_angle);
	
	if (self.ammo_nails <1)
	{
		self.weapon = W_BestWeapon();
		W_SetCurrentAmmo ();
		return;
	}
	sound (self, chan_weapon, "weapons/rocket1i.wav", 1, attn_norm);
	self.attack_finished = time + 0.2;
	self.currentammo = self.ammo_nails = self.ammo_nails - 1;
	dir = aim (self, 1000);
	launch_spike (self.origin + '0 0 16' + v_right*ox + v_up*ox2, dir); // sets spike direction

	self.punchangle_x = -2;
};


/*
===============
launch_gatling
===============
*/
void(vector org, vector dir) launch_gatling =  
{
	newmis = spawn ();
	newmis.owner = self;
	newmis.movetype = MOVETYPE_FLYMISSILE;
	newmis.solid = SOLID_BBOX;

	newmis.angles = vectoangles(dir);
	
	newmis.touch = spike_touch;
	newmis.classname = "spike";
	newmis.think = SUB_Remove;
	newmis.nextthink = time + 6;
	setmodel (newmis, "progs/spike.mdl");
	setsize (newmis, VEC_ORIGIN, VEC_ORIGIN);		
	setorigin (newmis, org);

	newmis.velocity = dir * 1000;
};

void() W_FireGatling =
{
	local vector	dir;
	local entity	old;
	
	sound (self, CHAN_WEAPON, "weapons/spike2.wav", 1, ATTN_NORM);
	self.attack_finished = time + 0.2;
	self.currentammo = self.ammo_nails = self.ammo_nails - 2;
	dir = aim (self, 1000);
	launch_gatling (self.origin + '0 0 16', dir);
	newmis.touch = superspike_touch;
	setmodel (newmis, "progs/s_spike.mdl");
	setsize (newmis, VEC_ORIGIN, VEC_ORIGIN);		
	self.punchangle_x = -2;
};


Step 3
Now open up player.qc . Above the line: void() player_light1 =[$light1, player_light2 ] insert these lines:


void() player_gat1   =[$nailatt1, player_gat2  ]  // runs gat2 next
{
	self.effects = self.effects | EF_MUZZLEFLASH;

	if (!self.button0)
		{player_run ();return;}
	self.weaponframe = self.weaponframe + 1;
	if (self.weaponframe == 9)
		self.weaponframe = 1;
	SuperDamageSound();
        W_FireGatSpikes (-8, 0);  // fires a spike to the left 
	self.attack_finished = time + 0.2;
};
void() player_gat2   =[$nailatt2, player_gat3  ]  // runs gat3 next
{
	self.effects = self.effects | EF_MUZZLEFLASH;

	if (!self.button0)
		{player_run ();return;}
	self.weaponframe = self.weaponframe + 1;
	if (self.weaponframe == 9)
		self.weaponframe = 1;
	SuperDamageSound();
        W_FireGatSpikes (0, 8);  // fires a spike up 
	self.attack_finished = time + 0.2;
};
void() player_gat3   =[$nailatt1, player_gat4  ]  // runs gat4 next
{
	self.effects = self.effects | EF_MUZZLEFLASH;

	if (!self.button0)
		{player_run ();return;}
	self.weaponframe = self.weaponframe + 1;
	if (self.weaponframe == 9)
		self.weaponframe = 1;
	SuperDamageSound();
        W_FireGatSpikes (8, 0);  // fires a spike to the right
	self.attack_finished = time + 0.2;
};
void() player_gat4   =[$nailatt2, player_gat1  ]  // back to 1
{
	self.effects = self.effects | EF_MUZZLEFLASH;

	if (!self.button0)
		{player_run ();return;}
	self.weaponframe = self.weaponframe + 1;
	if (self.weaponframe == 9)
		self.weaponframe = 1;
	SuperDamageSound();
        W_FireGatSpikes (0, -8);  // fires a spike down
	self.attack_finished = time + 0.2;
};


Step4
Now find the W_Attack function in weapons.qc . Change these lines:

	else if (self.weapon == IT_SUPER_NAILGUN)
	{
                player_nail1 ();
	}

Add in these lines:
	else if (self.weapon == IT_SUPER_NAILGUN)
	{
                player_gat1 ();
	}


Step 5
Woohoo! You're all ready to compile and run. Have fun...
