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 create the famous “guess the number” game!
Continue readingThe 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.
Continue readingPrograms in the previous post always lead to the same result. Here, I show you the basics of branching, or how to change the flow of a program depending on cases.
Continue readingIn the first post, we saw how to install an IDE and how to display a message; it is time to add some interaction with the player.
Continue readingIn this series, I propose to discover Python and design patterns. The Python language is today one of the best language to discover programming. At the same time, I will also introduce design patterns, a collection of programming recipes that give many good ideas when creating programs. In this first post, we see the Spyder IDE and the print() function.
Continue readingThe paperback version of my book “Learn Design Patterns with Game Programming” is finally out!
The Kindle version is updated with some improvements and is still freely available if you subscribed to Kindle Unlimited.
In this post, I add the keyboard management to the facade, and I propose a way to detect key sequences. These sequences are used, for example, in games like Street Fighter II, where characters move according to specific key combos.
Continue readingGraphic libraries usually provide methods to draw text on the screen. These handy methods are often quite slow to run because they recompute many parameters at each call. To save computational time, the flyweight pattern can be used to provide text parameters with low memory and
After loading a level, I now propose to add interaction with the use of a mouse. This will be an opportunity to see two other patterns: the Observer Pattern to handle mouse events, and the Game Loop Pattern for synchronization between controls, updates, and display.
Continue readingIn this article, I propose to use the Visitor Pattern to easily load a level. The GUI facade in the previous post is used to display the level. This pattern allows (among other things) to easily browse a data structure to extract information. In our case, it is an XML file created by “Tiled Map Editor” which is analyzed to load a level in memory.
