[MWForum]Microworld's EX a bug in reworked 'squish' game

[Wendy Petti]

I think I see another factor contributing to the error message.  The color
"cyan" has the instruction "raiselevel" which is triggered whenever any
turtle touches that color.  But in fact you only want the Fred turtle
passing over cyan to trigger the "raiselevel" procedure, since Fred is the
one turtle you are controlling.  (By the way, it is *very* hard to see a
black turtle on a black background... is that intentional?  I set Fred to
red so that I could see what was going on.)  If each turtle zooming over
cyan raises the speed by one level, then within moments you'll have
surpassed the top speed permitted on the slider.  Anyhow, Fred has a private
"OnColor" rule to run the raiselevel procedure when he touches cyan.  So if
you edit the color cyan (right-click on the color and select "edit cyan")
and remove the instruction (raiselevel), then Fred will be the only turtle
that will respond to cyan.

If you simply remove the raiselevel procedure without removing cyan's
instruction, you will get a different error message every time a turtle
touches cyan:
I don't know how to raiselevel

If you remove cyan's instruction so that Fred is the only turtle who ever
receives the message to "raiselevel," then it is not necessary to edit the
raiselevel procedure to add his name to the command involving homebase, as
Daniel suggested, for Fred will be the only turtle who will ever receive the
command.
