• Be resilient – Don’t expect to have a game in the first session.
• Be strategic – Focus on one thing at a time

A suggested order:

1. Choose your sprite
   1. from library?
   2. Search online for picture
      1. search for png files, eg search “zebra png”
      2. save image as…
      3. in Scratch, import from file
      4. ** edit in Scratch to get 2 (or more) costumes
2. Make your sprite move
   1. keyboard/mouse controls
3. Design your background(s)
   1. decide what is actually the background
      1. obstacles, coins etc to collect,… may be better as sprites
   2. photo background
      1. search online and save image as…
      2. make sure they are marked for reuse
      3. be careful if you want your sprite to react to colours

• Open Scratch page, click file – upload from my computer – find your file
• Use catch up cards and each other, but try to think for yourself first –  can you work it out?

So far we have done…

Use catch up cards if you need to do the following steps:

• CAT
• • When left arrow pressed, turn left 15 degrees
  • When right arrow pressed, turn right 15 degrees
  • Forever move forward
  • Forever change costume – walking
• BACKGROUND
  • Draw maze walls one colour
  • Draw start and finish places (could be text or picture)

Next steps

• if cat hits the wall – stop (put this in the moving block)
• make a coin sprite
  • show at the beginning
  • hide when sprite touches (forever checking)
  • make a variable called “score” (data blocks)
  • add one to score when sprite touches coin
• Add another maze to the backgrounds
  • Get it to change background when you finish the maze
