Re: More interesting Heatbugs...

[pauljohn]

To see this effect more clearly, one can change the bug color from
"generic green" to shades that describe the ideal temperature the bug
is seeking.  I made these changes.

In HeatbugObserverSwarm.m, add this line after the [colormap setColor:
65 ...] line that is in there:
  for (i=0; i < 64; i++)
   [colormap setColor: (i+66) ToRed: .3 Green: (double)i / 65 Blue: .5];
In HeatbugObserverSwarm.m, comment out the previous color assignment:
 //[[heatbugModelSwarm getHeatbugList] forEach: M(setBugColor:) : (void *) 64];

In HeatbugModelSwarm.m, go to line 198 or so (the part where the bugs
are being created), and add a creation statement that gives the bug a
color based on the extremity of its ideal temp.

     [hbug setBugColor: (int)
     (66.0+((65.0)*(idealTemp-minIdealTemp)/(maxIdealTemp-minIdealTemp)))];
    printf("BUG %d REPORTING, with tempideal %d color %f \n,", i, idealTemp,
    (66+(65.0)*(idealTemp-minIdealTemp)/(maxIdealTemp-minIdealTemp))); 

(the second command is there for debugging).
     
When I do this change, I see the cool-seeking bugs are blue, the
medium-seeking ones are pale green, and the ones that want it hot are
bright green.  I hope you to do to.

I find that Chris's conclusion about which bugs are moving the most is
not necessarily correct. It seems to depend on the total number of bugs
in the simulation (ambient heat).

Looking at this again gave me a new question, however.  I wanted to
make a two-color bug, perhaps a color in the center to show his
"permanent" ideal color and an outer edge that shows the time-varying
color to represent unhappiness.  Can anyone think of a way I might do
it?
