Up syntax

Example​

The up block is useful to take advantage of the 3D features of StarLogo. By adding the up block, we create a more realistic model of 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.

Up example code

Notes​

The Up block moves agents in the positive z direction in 3D space. Be careful to keep agents within valid z coordinates.
