Running in W95

[David Aliaga]

Hello Everybody.

I am running a simulation with Swarm for W95. But I
got very nasty and strange problems. I tried my best
to see what is happening, but now I can help but ask
help.

When I ran the simulation I wrote I got the panel and
the probes for ModelSwarm and ObserverSwarm. And
everything is ok. The problems starts when I press
Start or Next. I got the ZoomRaster with my agents but
the drawing is awfully wrong. To the difference with
the examples (like HeatBugs) I cant see the agents
moving but only a green spot covering the black. And
when I click with the right botton to see a probe of
the agents the program crash. I tried gdb but it is
awfully confusing when used with ObjC cause I cant
print the values of the instance variables of the
model. Anyway Attached is the results of backtrace I
made in gdb

The simulation is completely simple (I wanted to be
sure it runs before applying the learning module I am
working with) Just 4 agents moving randomly and a prey
moving randomly too. That's it.

When I ran the applications or when I make the
examples in the tutorial everything goes fine, I can
probe the agents (the bugs in simpleObeserverBug2 for
example) so the instalation seems to be OK. My code is
the problem, but I have tried and review everything
and I am completely frustrated. Could Someone have an
Idea what is going on?

David

None of the files mentioned are mine but are from the Swarm distribution 
so I dont know what this could mean
