Hi,
I resending this message since I hadn't heard back from anyone
(Ken)...Plus, I added some extra notes at the end of it...I have to have
this done by Friday morning so any help would be much appreciated...

Since then I also attempted to make a function within HeatbugModelSwarm,
called reproduce.  I added a Probe item called "haveSex" this is the
level of unhappiness where a heatbug would clone itself.  Then I had a
flag interior to the heatbug, called happyFlag.  It was set to 1 if they
were unhappiness < haveSex, otherwise its 0.
Then the reproduce method in HeatbugModel Swarm was basically the same
as the create Heatbug:


  [world setOverwriteWarnings: 0];

  if (unhappiness < haveSex) {  

    Heatbug * newbug;
    int newIdealTemp, newOutputHeat;

    //The new heatbug "inherits" state variables from its parent.

    newIdealTemp = idealTemp;
    newOutputHeat = outputHeat;

    // Create the heatbug, Add it to the list, and initialize the state
varibles.

    newBug = [Heatbug createBegin: [self getZone]];
    [newBug setWorld: world Heat: heat];
    newBug = [newBug createEnd];

    [heatbugList addLast: newBug];

    [newBug setPixmap: bugPixmap];
    [newBug setIdealTemperature: newIdealTemp];
    [newBug setOutputHeat: newOutputHeat];

    [newBug setX: (x + 3) Y: y]   //put the new bug near the parent. 
Theres a chance
                                  //that the baby will overwrite another
bug...I'll
                                  //fix that later...[grin] 
  }
  [world setOverwriteWarnings: 1];                // ok, done cheating.

  return self;
}


I get all kinds of errors, including x,y not declared, createBegin
declared but never used, and many others.
I plan to then put this call in the modelActions stuff something like:

[modelActions createActionForEach: heatbugList reproduce]

will something like this work?  How else can I do this?

Im I not approaching this right?  Can anyone offer some suggestions of a
better way to do this?
