Discover Python and Patterns (12): Command pattern
The implementation of the Game Loop pattern in the previous post is not good: I propose to use the Command pattern to get a better one. This pattern allows separating input handling and game updating.
Discover Python and Patterns (11): Class
I propose to introduce Python classes to implement the Game Loop pattern. Using these tools, I show how to refactor the code in the previous post to get a more robust and readable program.
Discover Python and Patterns (10): Keyboard
Thanks to the Pygame library we installed in the previous post, we can draw 2D graphics. In this post, I propose to introduce controls with the keyboard as well as some improvements like window centering and frame rate handling.
Discover Python and Patterns (9): Pygame
In the previous posts, I introduced enough of Python and patterns to start creating games with graphics using the Pygame library.
Discover Python and Patterns (8): Game Loop pattern
The time has come to see our first design pattern: the Game Loop Pattern! This pattern can give us many good ideas to refactor our game in a very effective way.
Discover Python and Patterns (7): Functions
It is now time to organize/refactor our code! When you begin, this is a strange process since the final code does the same as before. However, refactoring is the only way to create a code easy to maintain and expand.
Discover Python and Patterns (6): Random
In the previous post, the magic number is always the same. I propose now to introduce random numbers to change the magic number every time we launch the game. I also present imports and more on integers.
The source code of my book is now available on github
The source code of my book “Learn Design Pattern with Game Programming” is now available on github: https://github.com/philippehenri-gosselin/patternsgameprog. If you find any bug, comments here or issues on github are welcome 🙂
Discover Python and Patterns (5): Integers
In previous posts, I only used strings and booleans. In this one, I use a new data type called “int” (for integer) that allows the storage and computation of natural numbers (numbers without a decimal part). I use them to … Continue reading
Discover Python and Patterns (4): Loops
The previous game only allows one try: you have to restart it to propose another word. In this post, I introduce loops, and I use them to repeat the game until the player finds the magic word.
