Example
In this model, an epidemic has broken out in a population. Yellow agents are uninfected, red agents are infected, and blue agents are immune. Red agents spread the disease by sneezing, and yellow agents can catch the disease by coming into contact with sneeze particles created by red agents. The line graph to the left of spaceland keeps track of the total amount of infected, uninfected, and immune agents in the population, by using the ‘count within with’ block. Since the coordinates of spaceland range from (-50, -50) to (50, 50), it is more than sufficient to count within 200 steps.
Common Uses
- A common use of the
count [▼] within [_] steps with [▼] = [_]block is to monitor the total population of agents of a select breed AND trait. To do this, simply ask The World agent to count the number of agents within some large number of steps (400 will do).
