3. Scripting for the backdrop
The backdrop needs to be switched to Maze every time the game starts.
4. Writing scripts for the sprite Beetle
Now write a script for the sprite Beetle to be able to move forward and turn direction under the control of a button. The
workflow is as follows.
• When the green flag is clicked, set the Beetle angle to 90, and the position to (-134, -134), or replace it with the
coordinate value of your own placed position. Create the variable flag and set the initial value to -1.
