Video instructions 2

  1. Scratch cat script
    1. Make Scratch move up, down, left, right when you press the arrow keys:
      1. You will need 4 groups of blocks
      2. Events – when up arrow pressed…ScreenHunter_155 Feb. 22 08.16
      3. Up = change y by  5 ; Down = change y by -5ScreenHunter_157 Feb. 22 08.17
    2. Test it out by trying to get past the Egyptian god!

  • Think:
    • How can we make the cat go a bit faster?
    • How could we stop Scratch going through the walls?

LF3 Follow a path

Video instructions 4

  1. Look at the Roman soldier script – can you work out how it works?
  2. RH-click on the Roman soldier and duplicate to get two more – one for each level
  3. Replace the glide blocks by doing the following:
    1. move it to where you want it
    2. select glide blocks (they will have the correct numbers for x and y)
  4. Test the game – make sure it is just possible to get past by going into the tunnels.  Change the speed of the cat and/or soldiers if needed.

LF4 Makes sprites interact

Y5 LF Planning a game – decomposition (2)

May 142018
 
  1. Finish your game plan (Google drive – classroom)
  2. Decomposition means breaking a problem or situation down into simple pieces.  When we are programming, we need to break the game down into simple bits that we program one at a time.
  3. Start with one part of your plan, eg how the main character moves.
  4. Break it down:
    1. Animation, eg walking
      1. Draw two or more costumes
      2. Example walking animation
      3. Make them swap all of the time when the greem flag is pressed.
    2. Controls
      1. Arrow keys
        1. Left – change x by -5
        2. Right – change x by 5
        3. Up – change y by 5
        4. Down- change y by -5
      2. Point int the right direction
        1. Left – point in direction – left
        2. Right – point in direction – right
      3. Rotation style: Left-right
  5. Now choose another element of your plan to work on
    1. Break it down…
