Modelling - Controlling the Sprite

Scratch Project

Part 1 - Main Sprite

1. Add a new sprite (click the blue Cat Face button) and click the paint brush from the pop up menu
   
2. Make sure that you are on the "Costume" tab and use the square tool to draw a small square. MAKE SURE the squares centre is drawn over the cross hairs (see cross symbol)
   
3. Click on the code window and code the following sequence.
   
4. Test your code by pressing the green flag button. You should be able to control the direction that your sprite moves in by using the arrow keys.

Scratch Project

Part 2 - Backgrounds

1. You now need to create 3 backgrounds for your levels. The game is a maze and if the sprite touches the side of the maze it returns to the start.
   
2. Make sure your sprite is at the start of your maze. I recommend starting the sprite in the same place for all your levels.
   
3. You need to use the square tool to create a suitable maze.
   
4. It needs to large enough for the sprite to be able to travel from one end of the game to the other.
   
5. It needs to have a colour square at the end of the maze to allow the player to win (more on this later)
   
6. Once you have completed the first level (backdrop) click the picture icon in the bottom left and click the paint brush.
