Re: Scheduling Question (off-by-one error)

[Paul Johnson]

I'm not digging through the detail of our model, but I've encountered 
this problem before.

Look at your activateIn method and the order in which the things are 
activated.  I think you will find this in activateIn:

  [modelSwarm activateIn: self];
  [displaySchedule activateIn: self];

Which causes the model steps to be ahead of the display steps. Try 
reversing them.

Before my recent deep exploration of Scheduling for the last Swarmfest, 
I think I worked around this by making agents wait until time 1 to take 
a step. You could consider that as well.
