Chapter 9.

#1 The swarm.cs on the cd is not the same as in the book.

Time to put down the coffe and start typing :)

#2 I've also noticed swarm beasties don't detect collisions. I've implemented this cludgy hack but I think there is a better way. I don't know how to get them to detect projectile collisions - any help would be good. This collision below is for a sword swipe or punch...I just don't like the weapon handling the player/enemy death and it shouldn't.

%start = %player.getEyeTransform();
   %end = VectorAdd(%start,%vec);
   %found = ContainerRayCast (%start, %end, $TypeMasks::PlayerObjectType, %player);

   // ~~~~~  if we got a target  then damage it  ~~~~~~~~~~~~~
   if (%found>0)
   {
      // damage it
      %foundObject = getword(%found,0);
	     if((%foundObject.getType() & $TypeMasks::PlayerObjectType) && %foundObject.getState() !$= "Dead")
         {
            %foundObject.applyDamage(%this.damage);
            
            if (%foundObject.getState() $= "Dead")
            {
               %foundObject.playDeathCry();
               %foundObject.playDeathAnimation();
               %foundObject.setDamageFlash(0.75);

               // Release the main weapon trigger
               %foundObject.setImageTrigger(0,false);

               // Schedule corpse removal.  Just keeping the place clean.
               %foundObject.schedule($CorpseTimeoutValue - 1000, "startFade", 1000, 0, true);
               %foundObject.schedule($CorpseTimeoutValue, "delete");
            }
         }
    }

#3 Well here's my second cludgy hack for projectile collisions on the swarm. They don't take radius collision damage for some reason. I put a break point in, in radiusDamage.cs and the code gets in there but the swarm beasties don't actually recieve damage.

function Projectile::onCollision(%this,%obj,%col,%fade,%pos,%normal)
{
   // Apply damage to the object all shape base objects
   if (%col.getType() & $TypeMasks::ShapeBaseObjectType)
   {
      // damage it
      if((%col.getType() & $TypeMasks::PlayerObjectType) && %col.getState() !$= "Dead")
      {
         %col.applyDamage(%this.directDamage);
         
         if (%col.getState() $= "Dead")
         {
            %col.playDeathCry();
            %col.playDeathAnimation();
            %col.setDamageFlash(0.75);

            // Release the main weapon trigger
            %col.setImageTrigger(0,false);

            // Schedule corpse removal.  Just keeping the place clean.
            %col.schedule($CorpseTimeoutValue - 1000, "startFade", 1000, 0, true);
            %col.schedule($CorpseTimeoutValue, "delete");
         }
      }
      else
      {
         %col.damage(%obj,%pos,%this.directDamage,"Fireball Damage");
      }
      
   }

   // Radius damage is a support scripts defined in radiusDamage.cs
   // Push the contact point away from the contact surface slightly
   // along the contact normal to derive the explosion center. -dbs
   radiusDamage(%obj, %pos, %this.damageRadius, %this.radiusDamage, "Radius", %this.areaImpulse);
}

#4 THis doesn't seem to work very well.. they don't seem to follow each other and I get a ton of "friendless" results. Is that normal?
