Description:
     Below is a source code example of an alternative monster AI
for lobbing grenades and other similar projectiles such as gibs.

     The following code will let ogres or zombies lob their
projectiles at a standing target ANYWHERE within a radius
of 1000 with frightening accuracy.

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


OGRE.QC (or ZOMBIE.QC)
(All the changes will be made in the function
void() OgreFireGrenade =
 or equivalent in other qc files.

 After the line

 	local	entity missile, mpuff;

 insert the following code...)


//-------------------------------------------------------- New Code --------
        local   float   dist;   // Distance between attacker and target.
        local   float   base;   // This dictates how fast the projectile
                                //   will fly up when it is launched.
        local   float   g;      // Gravity -- g = 1 is Earth gravity.

//------------------------------------------------------//
//  800 is normal (Earth) gravity.  800 * 0.00125 = 1.  //
//------------------------------------------------------//
        g = (cvar("sv_gravity")) * 0.00125;   // Find gravity in terms of g.
//--------------------------------------------------------------------------


(Then, replace the following line

	missile.velocity_z = 200;

 with the code below...)


//-------------------------------------------------------- New Code --------
        dist = vlen(self.enemy.origin - self.origin);
//--------------------------------------------------------------//
// The monster will lob a projectile that is guaranteed to hit  //
// a stationary target within a radius of 1000.  If the target  //
// is moving, it may aim the projectile a bit lower to counter  //
// any attempt to run underneath the grenade.                   //               //
//--------------------------------------------------------------//
        if (self.enemy.velocity_x || self.enemy.velocity_y)
                if (random() < 0.9)
                        dist = dist - random()*300;
        if (dist > 900)
                base = 200+((dist - (200 - (dist * 0.2)))*0.5);
        else if (dist > 700)
                base = 200+((dist - (200 - (dist * 0.15)))*0.5);
        else if (dist > 500)
                base = 200+((dist - (200 - (dist * 0.1)))*0.5);
        else if (dist > 200)
                base = 200+((dist - 200)*0.5);
        else
                base = 200;

        missile.velocity_z = (missile.velocity_z + (base * g));
