Use PYSDL2 to implement an entry guide for 2D game development

PYSDL2 is a Python library for 2D games. It is a Python binding based on Simple DirectMedia Layer (SDL).This article will introduce how to use PYSDL2 for the entry guide for 2D game development.We will cover the explanations of the code and related configuration. First, we need to install the PYSDL2 library.You can use the PIP command to install. The command is as follows: pip install PySDL2 After the installation is completed, we can start writing code. python import sdl2 import sdl2.ext # Initialize SDL sdl2.ext.init() # Create a game window window = sdl2.ext.Window("2D Game", size=(800, 600)) window.show() # Create a rendering device renderer = sdl2.ext.Renderer(window) # 创 创 sprite_factory = sdl2.ext.SpriteFactory(renderer=renderer) sprite = sprite_factory.from_image("sprite.png") # 游戏 游戏 游戏 running = True while running: # 处 for event in sdl2.ext.get_events(): if event.type == sdl2.SDL_QUIT: running = False break # renderer.clear() # Rendering elf sprite.render(0, 0) # Update screen renderer.present() # 清 清 sdl2.ext.quit() The above code first introduced the necessary SDL2 extension library and initialized SDL.Then create a game window and display it.Next, we created a renderer to draw game elements.Then, we used the Elf Factory to create an elf and load texture data from the image file. In the main cycle of the game, we handle the SDL event and achieve the refresh the game screen by clearing the renderer, rendering elf, and updating the screen.When receiving the exit incident, we set the Running logo to false to exit the cycle. Finally, after exiting the game cycle, we call the SDL2.Ext.quit () function to clean up SDL related resources. It should be noted that we assume that there is already an elf image file called "sprite.png".You can replace it with your own image file to ensure that the file path is correct. In addition to the above code, we also need to do some related configurations. First, make sure your Python environment is installed with PYSDL2 libraries.If it is not installed, you can use the PIP command mentioned above for installation. Secondly, you need to ensure that the SDL library and its development package have been installed.If you are under the Linux system, you can install the following command: sudo apt-get install libsdl2-dev If you are on other operating systems, you can get the SDL library that suits your system by accessing the official website of the SDL (https://www.libsdl.org/index.php). Finally, you need to have a suitable development environment to write and run the Python code.You can choose to use IDE, such as pycharm, or use only text editors, and run code in the command line. In summary, this article introduces an entry guide for 2D game development using PYSDL2.We have written a simple code example from installing PYSDL2 and explained the detailed information of the code and related configuration.I hope this article can help you get started with PYSDL2 and start your 2D game development journey!
