The count within steps

Provides the number of agents of a selected breed within a specified radius of itself. Use 200 steps to cover the entire terrain.

count [▼] within [_] steps is a code block part of the Detection drawer.

Usage

count [▼] within [_] steps is used to provide the number of agents of a selected breed that exist within a given step limit in Spaceland.

Syntax

The Create Each Do Block

Inputs in this block:

  1. a breed from the dropdown menu (to count)
  2. a number into the socket

Example

Count Within Steps example code

While the ‘mingle’ button is toggled on, agents with the color red are treated as having a disease and will spread that disease by sneezing. Agents proximal to the sneeze particles, as detected by the ‘count within’ block, will be more likely to contract the disease.

Common Uses

  • A common use of the count [▼] within [_] block is to monitor the total population of agents of a select breed. To do this, simply ask The World agent to count the number of agents within some large number of steps (400 will do).
