Part 4 - Bug Fix Challenges #

Bugs are things that don’t work quite right in your code. Absolutely all code has bugs in it when it’s first written. Let’s try to fix a couple now. For each bug you should follow this process:

Reproduce it. This means checking that you can see the bug happen.
Figure out why it’s happening.
Fix it!
Check that you can’t reproduce it any more.

Bug #1: When you die and start again, your score at the top of the screen doesn’t go back to zero.
Bug #2: If you crash in to the top pipe in just the right place your falling ghost can keep flying far enough to get a cheeky extra point.

Hint: You could try changing scroll_speed to make it easier to reproduce this bug.

Well Done!!! #

You’ve written a complete fully working game! Take some time to enjoy playing your creation! Remember there are values in the code like gravity, scroll_speed, and gap that you can tweak to try to make it more fun.

If you want to add more features to your game the PyZero documentation will help:

If you want to add something to the game then talk to a mentor about how you might do it. Here’s a few things you might want to try:

Make the bird stay still until the first flap
A high score feature so you can see your best score.
Starting the game with 3 lives so you can hit the pipes twice without dying
Collectible stars
Pipes that move up and down as they come towards you
Variable scrolling speed. Maybe flapping speeds you up
