Hello people, in this tutorial were gonna make a Grenade that sticks to walls or enemies, its one of my favs, i saw it somewere and i think it so cool, so i tried to make it, and it works (at least for me). So here is what you have to do:

Step 1

Open Weapons.qc and remplace the GrenadeTouch funtion with this:

void () GlueStick = {

   if ( (random () < 0.020) ) { // check for a random number

      self.think = GrenadeExplode; //maybe to explode
      self.touch = GrenadeExplode;

   } else {

      self.think = GlueStick; // maybe to Stick
      self.touch = GlueStick;

   }
   if ( ((self.enemy != world) && (self.enemy.health > 1)) ) {

      self.origin = self.enemy.origin;
      if ( (self.velocity == VEC_ORIGIN) ) {

         self.avelocity = VEC_ORIGIN;

      }

   }
   self.nextthink = (time + 0.100);

};

Step 2

Then under the above function insert this:

void () GlueTouch = {

   if ( (other == self.owner) ) {

      return ;

   }
   sound (self,CHAN_WEAPON,"misc/outwater.wav",TRUE,ATTN_NORM); // sound to make when it stick
   self.think = GlueStick;
   self.touch = GlueStick; // go to GlueStick when touching something
   self.nextthink = (time + 0.100);
   self.velocity = (self.velocity * 0);
   self.avelocity = VEC_ORIGIN;
   self.enemy = other;

};

Step 3

Now remplace the W_FireGrenade function with this:

void () W_FireGlue = {

   local entity missile;
   local entity mpuff;

   self.ammo_rockets = (self.ammo_rockets - 1);
   self.currentammo = (self.ammo_rockets - 1);
   sound (self,CHAN_WEAPON,"weapons/grenade.wav",TRUE,ATTN_NORM);
   self.punchangle_x = CONTENT_SOLID;
   missile = spawn ();
   missile.owner = self;
   missile.movetype = MOVETYPE_FLYMISSILE; // make the grenade fly
   missile.solid = SOLID_BBOX;
   makevectors (self.v_angle);
   missile.velocity = aim (self,1000);
   missile.velocity = (missile.velocity * 1000);
   missile.angles = vectoangles (missile.velocity);
   missile.nextthink = (time + MOVETYPE_FLY);
   missile.think = GrenadeExplode;
   missile.touch = GlueTouch;
   setmodel (missile,"progs/grenade.mdl");
   setsize (missile,VEC_ORIGIN,VEC_ORIGIN);
   setorigin (missile,self.origin);

};

Ok thats it... i love it... now go do it.. and tell me if there is any trouble. Cya
