This tutorial is a follow-up to the first MagSec4 Tutorial. This time we will add a button to change to a Secondary Mode of fire. In this case the Seconadry Mode will work only on the MagSec4, however it can be done to may other weapons quite easily. Note: to complete this tutorial you must have already completed the original Magsec4 tutorial.

Step 1

Open up Defs.qc and at the very bottom paste the following variables:

//Magsec4 Floats
.float  MAGSEC_MODE;
float       PRIMARY = 1;
float   SECONDARY   = 2;

Explanation: The first varible is the container for the mode. The next two variables are the modes: PRIMARY/SECONDARY.

Step 2

Once you've created the above variables open up Weapons.qc and scroll down to function ImpulseCommands. Then above QuadCheat paste the code block below:

if (self.impulse == 15)
{
    if (self.weapon == IT_NAILGUN)
    {
        if (self.MAGSEC_MODE == PRIMARY)
        {
            self.MAGSEC_MODE = SECONDARY;
            centerprint (self, "Secondary Mode of Fire\n\n Three Round Burst");
        }
        else if (self.MAGSEC_MODE == SECONDARY)
        {
            self.MAGSEC_MODE = PRIMARY;
            centerprint (self, "Primary Mode of Fire\n\n Single Shot");
        }
    }
}

Step 3

Now find the W_Attack function then find the following section:

else if (self.weapon == IT_NAILGUN)
{
    player_shot1 ();
    W_FireMagsec ();
    self.attack_finished = time + 0.25;
}

Replace the above with what follows:

else if (self.weapon == IT_NAILGUN)
{
    player_shot1 ();
    if (self.MAGSEC_MODE == PRIMARY)
    {
        W_FireMagsec ();
        self.attack_finished = time + 0.25;
    }
    else if (self.MAGSEC_MODE == SECONDARY)
    {
        if (self.ammo_nails < 3) return;    //If less than three nails don't fire
        W_FireMagsecBurst ();
        self.attack_finished = time + 0.6;
    }
}

Step 4

Once finished the above step save then open up Client.qc and find the PutClientInServer function. In that function find W_SetCurrentAmmo and above that put:

self.MAGSEC_MODE = PRIMARY;

This sets the mode to Primary on spawning.

Step 5

Save Client.qc and open Magsec4.qc. Scroll to the end and paste the following after W_FireMagsec:

void() W_FireMagsecBurst =
{
    local vector    dir, org1, org2, org3, case;
    local entity    old;

    makevectors(self.v_angle);
    case = aim (self,10000);

    if (self.ammo_nails < 3) return;    //If less than three nails don't fire
    self.currentammo = self.ammo_nails = self.ammo_nails - 3;

    sound (self, CHAN_WEAPON, "weapons/spike2.wav", 1, ATTN_NORM);

    //Origin For Bullet No. 1
    if (random() < 0.1) org1 = self.origin + '0 0 20'+(v_right * -2);
    else if (random() < 0.2) org1 = self.origin + '0 0 16'+(v_right * 3);
    else if (random() < 0.3) org1 = self.origin + '0 0 12'+(v_right * -1);
    else if (random() < 0.4) org1 = self.origin + '0 0 16'+(v_right * 1);
    else if (random() < 0.5) org1 = self.origin + '0 0 18'+(v_right * -4);
    else if (random() < 0.6) org1 = self.origin + '0 0 14'+(v_right * 4);
    else if (random() < 0.7) org1 = self.origin + '0 0 13'+(v_right * -3);
    else if (random() < 0.8) org1 = self.origin + '0 0 17'+(v_right * 2);
    else if (random() < 0.9) org1 = self.origin + '0 0 20'+(v_right * 1);
    else org1 = self.origin + '0 0 16';

    //Origin For Bullet No. 2
    if (random() < 0.1) org2 = self.origin + '0 0 20'+(v_right * -2);
    else if (random() < 0.2) org2 = self.origin + '0 0 16'+(v_right * 3);
    else if (random() < 0.3) org2 = self.origin + '0 0 12'+(v_right * -1);
    else if (random() < 0.4) org2 = self.origin + '0 0 16'+(v_right * 1);
    else if (random() < 0.5) org2 = self.origin + '0 0 18'+(v_right * -4);
    else if (random() < 0.6) org2 = self.origin + '0 0 14'+(v_right * 4);
    else if (random() < 0.7) org2 = self.origin + '0 0 13'+(v_right * -3);
    else if (random() < 0.8) org2 = self.origin + '0 0 17'+(v_right * 2);
    else if (random() < 0.9) org2 = self.origin + '0 0 20'+(v_right * 1);
    else org2 = self.origin + '0 0 16';

    //Origin For Bullet No. 3
    if (random() < 0.1) org3 = self.origin + '0 0 20'+(v_right * -2);
    else if (random() < 0.2) org3 = self.origin + '0 0 16'+(v_right * 3);
    else if (random() < 0.3) org3 = self.origin + '0 0 12'+(v_right * -1);
    else if (random() < 0.4) org3 = self.origin + '0 0 16'+(v_right * 1);
    else if (random() < 0.5) org3 = self.origin + '0 0 18'+(v_right * -4);
    else if (random() < 0.6) org3 = self.origin + '0 0 14'+(v_right * 4);
    else if (random() < 0.7) org3 = self.origin + '0 0 13'+(v_right * -3);
    else if (random() < 0.8) org3 = self.origin + '0 0 17'+(v_right * 2);
    else if (random() < 0.9) org3 = self.origin + '0 0 20'+(v_right * 1);
    else org3 = self.origin + '0 0 16';

    LaunchProjectile(org1); //Fire Bullet No. 1
    eject_case (((self.origin + (v_forward * 12)) + (v_up * 13)),case);
    LaunchProjectile(org2); //Fire Bullet No. 2
    eject_case (((self.origin + (v_forward * 12)) + (v_up * 13)),case);
    LaunchProjectile(org3); //Fire Bullet No. 3
    eject_case (((self.origin + (v_forward * 12)) + (v_up * 13)),case);

    self.punchangle_x = -2;
};

Step 6

That should be it. What you've done is create an impulse to allow the switching of Firing Modes, created a function for the Secondary Mode and made it so when spawning the mode reverts to normal. Once compiled go ahead and have fun with a gun of two modes. Marius
