Robot bop - Decomposition
Decompose means to break something down into small parts. Before we start coding, we can decompose the project to help us work out how to recreate the game for ourselves.

Decomposition
These are the blocks required to create one of the sprites in Robot bop. Can you can recreate the code accurately in your own Scratch project? You can use whatever sprite and background you like. Be creative!

Decomposition
Here is the correct answer. How did you do? Did you put all of the coding blocks in the correct place? What part of recreating the code did you find difficult?

Decomposition
If you want to add more sprites to the game you can right-click (or hold down ‘ctrl’), click on the sprite’s small icon and then select duplicate from the menu.

Decomposition
Change the wait time on this block to be something different for each sprite and they will all reappear at different times. This will make the game more interesting and fun to play.

Make sure that the wait time is between 1–5 seconds if you want your game to work like Robot bop. Look inside the code on the original Robot bop remix if you need some help!
