Description of the Modification
-------------------------------
     Ever since I have played around with my Buster patch,
I noticed a bug with the barrels in Quake:  Whenever a
radius attack destroys a barrel, that radius attack is
negated and the explosion of the barrel's takes its place.

     Since nothing in normal Quake (other than lightning
discharge underwater) had the explosive power of an exploding
barrel, this bug had very little if any effect in regular
Quake.  However, custom weapons which produce large, damaging
explosions, such as those that recreate the effects of a nuke,
could have their damaging effects spoiled if a barrel is
destroyed by the explosion.

     Below is some code that will fix this bug.  What it
does is delay the barrel explosion for a frame (0.1 sec.),
which will let *your* weapon do the damage first without
interference; then the barrel explodes immediately afterward.

     Feel free to cut-and-paste this code into your projects.


MISC.QC
(Go down to

	void() barrel_explode =

 and erase the *entire* function.

 Then insert the following two functions where
 the original void() barrel_explode used to be...)


//-------------------------------------------------------- Code Change -----
//  This fixes a bug in which barrel explosions cancel other explosions.
//  Here, the barrel explosion is delayed for one frame so that other
//  explosions can occur without interference from the barrel.
//--------------------------------------------------------------------------
void() barrel_damage =
{
	T_RadiusDamage (self, self, 160, world);
        setorigin(self, self.origin + '0 0 32');
        self.effects = self.effects | EF_MUZZLEFLASH;
	BecomeExplosion ();
};

void() barrel_explode =
{
	self.takedamage = DAMAGE_NO;
	self.classname = "explo_box";
        sound (self, CHAN_VOICE, "weapons/r_exp3.wav", 1, ATTN_NORM);
        particle (self.origin + '0 0 32', '0 0 0', 75, 255);
        self.nextthink = time + 0.1;
        self.think = barrel_damage;
};
//---------------------------------------------------------------- END -----
