Moves down by a specified number of steps.

Down block

Description​

The Down block will move any agent downwards in the "z" direction by the number of steps specified. This is a code block part of the Movement drawer.

Usage​

Will move any agent downwards in the "z" direction by the number of steps specified.

Syntax​

Inputs in this block:

  • A number (number of steps to move down)

Example​

The down block is useful to take advantage of the 3D features of StarLogo. By adding the down block this becomes a more realistic model predator-prey interactions and fish movement. To enable random vertical movement and keep all fish above ground, fish who fall below the valid range of z values are automatically raised above ground in the final if statement.

Down example code

Notes​

The Down block moves agents in the negative z direction in 3D space. Be careful to keep agents within valid z coordinates to prevent them from going below the terrain.
