Modifying a game

Creating games

In this unit, pupils will explore the concept of repetition in programming in the Scratch environment. Pupils will look at the difference between count-controlled and infinite loops. They will use their knowledge to modify, design and create games and animations that involve repetition.

Using repetition in programming to create a game

running commands multiple times in a loop

What does repetition mean in programming?

Which block in a programme makes an action continue without stopping until the programme ends?

What action do you use in a programme to make a sprite invisible on the stage?

because one loop will make all sprites move at the same speed

because each sprite needs its own loop to repeat its own actions

because loops can only be used for backgrounds

Why isn’t it enough to programme just one loop for an entire game with several sprites?

What is the term for making changes to code you have already written?

Which of these is a reason you might want to change an infinite loop in a game project?

What happens if you increase the value inside a loop that moves a sprite?

If you want another character to jump in the same way as your main character, what could you do?
