I never tried to play around with the gui objects before, but now I
think I may teach this and write a bit about it. This has me stumped. I
found a nice little tutorial by Nelson M in here:
http://www.santafe.edu/projects/swarm/archive/list-archive.9608/0015.html
This is quite a nice tutorial and wish I'd seen it before. ANyway, I
guess there is one feature outdated:
It says you can use the "copy" method of the Object class to create a
new heatbug, and then drag that ouput to the addHeatbug slot in
ModelSwarm. When I try that, I get this:
*** event raised for error: BlockedObjectAlloc
*** function: _i_Object_s__copy(), file: DefObject.m, line: 549
> Requested operation is defined by the Object superclass of the GNU
> Objective C runtime system, but is blocked from usage because its default
> implementation is incompatible with the model of zone-based allocation
> established by the defobj package. To allocate, free, or copy objects
> that use the defined model of zone-based allocation, one of the messages
> create:, createBegin:/End, drop, or copy: must be used instead.
*** execution terminating due to error
Aborted (core dumped)
>From the GUI, I can't see how to create a heatbug to drop into the
addHeatbug slot.
What do you think?
Please don't tell me this is a simple question that I could just read
about in a manual. Believe me, I tried...
