That Blue Square Thing

Scratch Programming - The Platform Game

The platform game is a very simple version of a classic platform game. It uses a black square as its hero.

The game only has one level to start with. It's up to you to design and build the new levels needed.

There's a YouTube video of the game being played here:

3. Play the game

Click the green flag to play the game. Try and figure out how to move the hero (the black square) and what each of the blocks do. There is only one level at the moment.

4. Look at the code:

The hero (the black square) is the only sprite. The code on this is quite tricky. Concentrate on the ways that colour blocks are used (the "if touching..." blocks). This is what makes the game work.

5. Design the next levels:

On paper, design what you think will make 3 or 4 good levels. Try and make each level a little more challenging. Perhaps there are more red blocks, or the yellow block is high up? You could try and include some new blocks or power-up items if you feel brave.

6. Build the next level:

  1. Click on the Stage area at the bottom right
  2. Now click on the Backdrops tab at the top left
  3. IMPORTANT: Right click on backdrop1 and Duplicate. This copies the backdrop so that you have a blank one to use later
  4. Build the level. It's easiest to use rectangles, circles and lines to do this and fill them with the colour you need

Each level needs a black baseline drawn for the hero to bounce on.
