Re: Q: re dynamic scheduling

[Benedikt Stefansson]

Hi Geoffrey,

A schedule has to be activated in order to be executed. In this case the
schedule instance lives in a limbo - the SwarmProcess, which is running the
"virtual computer" never calls the schedule since it doesn't know about it.

Try adding a [schedule activateIn: swarmContext] line to the program, where
swarmContext is either "self" if this is in modelSwarm or a pointer to an
instance of the Swarm that this object was created in. Activate the schedule
at the beginning of time and then the -myDynamicScheduleTrigger method should
work as advertised.

Check out swarmapps/mousetrap/MousetrapModelSwarm.m for examples.

Regards,
-Benedikt
