Scratch character commands

A
Andrew Willetts

This guide teaches the user to create character movement commands in Scratch. It shows how to: 1. Create scripts that use arrow keys to move the character up, down, left, and right by changing the character's direction and number of steps. 2. Add a "stop script" block to end each movement script. 3. Create an additional script using a flag click to make the character bounce back if it reaches the edge of the screen.
