How to Program Roamer ScratchX

In this course, we explain the Roamer ScratchX commands and how you can make Roamer and Roamer Sprites work together.

Types of Commands

You’ll learn Roamer ScratchX has three different types of commands.  You’ll find out what these are and how they compare with one another.

Type Description Example
Scratch Block This is the regular Scratch Block.  This will only control Scratch Sprites.
Roamer Extension Block This is a normal Roamer command, in a Scratch form.  These blocks will only control Roamer
Composite Blocks This is a set of custom scratch blocks that control both  sprite and the robot.

Example Program Scratch Script for a Square

This will move a Roamer Sprite in a square pattern with sides 10 steps long.  It will not move the Roamer robot.
