Discover Python and Patterns (2): Basic interaction
In 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.
Discover Python and Patterns (1): Start
In 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 … Continue reading
AWT GUI Facade (8): Keyboard and key sequences
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.
AWT GUI Facade (7): Draw text
Graphic 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 … Continue reading
AWT GUI Facade (6): Mouse and Game Loop
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 … Continue reading
AWT GUI Facade (5): Load a level
In 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 … Continue reading
AWT GUI Facade (4): Draw with tiles
I continue the extension of the graphic facade (see previous article), with here the addition of a very classic form of drawing for video games: tiles. These make it possible to compose an image using small images called tiles. There … Continue reading
AWT GUI Facade (3): Display an image
The facade seen in the previous article has only an interface with its methods. It is also possible to enrich a facade with additional interfaces, connected to each other by various means. To illustrate it, I propose to add image … Continue reading
AWT GUI Facade (2): Draw
In this article, I propose to continue the design of a facade for a 2D tile game (previous post). I add two new features: creation/destruction of the window, and basic drawing. We manage each feature using methods in a GUIFacade … Continue reading
AWT GUI Facade (1): Display a window
In this series, I propose to discover the Facade Pattern. In short, this pattern defines an interface that allows a reduced and simplified use of a set of features. To illustrate, we design a facade of the AWT graphics library … Continue reading
