9. Stopping condition

This 9th step illustrates how to use the pause action to stop a simulation.

Formulation

  • Addition of a stopping condition for the simulation: when there is no more prey or predator agents, the simulation stops

Model Definition

We add a new reflex that stops the simulation if the number of preys or the number of predators is zero.

global {
...
reflex stop_simulation when: (nb_preys = 0) or (nb_predators = 0) {
do pause ;
}
}
