Need some help at developing a minigame (school-project)

[Stahfeli]

Hello, i want to create a mini game for school. I want several "rocks" / elements to drop at different speed and at the bottom you control an element with right left buttons.

my Question: how can i reset the "rocks" to their starting Position when they reach like y=200. was thinking about using case structure.

greetings felix

You only need one loop for everything. Instead of moving controls around, you could use a picture indicator and draw squares.

Also have a look at these old thetris discussions for some ideas.
