Lab 9: Sprites and Walls

Goal: Create a landscape of wall objects that the user must navigate around to collect coins. This will help practice using for loops to create and position multiple items.

  • Step 1: Start with one of the move with walls examples. Use either the Move with Walls example or the Move with a Scrolling Screen example.
  • Step 2: Create a more complex arrangement of walls. Make sure the walls don’t allow the user to go off-screen. 6 points, based on how complex the arrangement.
  • Step 3: Update the graphics. Use multiple types of blocks for the walls. Maybe change the character. 4 points, one point for each graphic used that wasn’t part of the base example.
  • Step 4: Add coins (or something) for the user to collect. 4 points, based on the complexity of the coin layout.
  • Step 5: Keep score of how many coins were collected, and display on-screen. 4 points.
  • Step 6: Add a sound to play each time the user collects a coin. 2 points.


Don’t move the player twice!

The command self.physics_engine.update() moves the player while checking for walls. The command self.all_sprites_list.update() will move the player WITHOUT checking for walls. Don’t do both commands. You’ll end up “walking through walls.” If you have other sprites to update, update only those sprites. For example: self.coin_list.update().
