Introduction to pyglet

pyglet is a powerful library for Python that enables efficient development of games and multimedia applications. Renowned for its performance and having a rich and diverse API, pyglet boasts simplicity and flexibility, perfect for both beginners and advanced developers. This guide introduces you to various key APIs in pyglet and provides examples to help you get started.

Installing pyglet

First, ensure you have installed pyglet. You can easily install it via pip:

  pip install pyglet

Creating a Simple Window

Let’s start by creating a simple window:

  
    import pyglet

    window = pyglet.window.Window()

    @window.event
    def on_draw():
        window.clear()

    pyglet.app.run()
  

Rendering Text

Rendering text on the window is straightforward:

  
    import pyglet

    window = pyglet.window.Window()
    label = pyglet.text.Label('Hello, pyglet!',
                              font_name='Times New Roman',
                              font_size=36,
                              x=window.width//2, y=window.height//2,
                              anchor_x='center', anchor_y='center')

    @window.event
    def on_draw():
        window.clear()
        label.draw()

    pyglet.app.run()
  

Handling User Input

pyglet also allows us to handle user inputs like keyboard and mouse events:

  
    import pyglet

    window = pyglet.window.Window()

    @window.event
    def on_key_press(symbol, modifiers):
        if symbol == pyglet.window.key.A:
            print('The "A" key was pressed.')

    @window.event
    def on_mouse_press(x, y, button, modifiers):
        if button == pyglet.window.mouse.LEFT:
            print(f'The left mouse button was pressed at ({x}, {y})')

    pyglet.app.run()
  

Loading and Displaying Images

Here’s how you can load and display an image:

  
    import pyglet

    window = pyglet.window.Window()
    image = pyglet.resource.image('example.png')

    @window.event
    def on_draw():
        window.clear()
        image.blit(100, 100)

    pyglet.app.run()
  

Playing Sounds

Playing sound files is also very intuitive:

  
    import pyglet

    music = pyglet.resource.media('background.mp3')
    music.play()

    pyglet.app.run()
  

Setting up Animations

Animate your images with ease:

  
    import pyglet

    window = pyglet.window.Window()
    animation = pyglet.resource.animation('animation.gif')
    sprite = pyglet.sprite.Sprite(animation)

    @window.event
    def on_draw():
        window.clear()
        sprite.draw()

    pyglet.app.run()
  

Complete Example: Simple App with Multiple Features

Here’s a complete example that incorporates multiple features:

  
    import pyglet

    window = pyglet.window.Window(width=800, height=600)
    label = pyglet.text.Label('Hello, Pyglet!',
                              font_name='Times New Roman',
                              font_size=36,
                              x=window.width//2, y=window.height-50,
                              anchor_x='center', anchor_y='center')
    image = pyglet.resource.image('example.png')
    music = pyglet.resource.media('background.mp3')
    animation = pyglet.resource.animation('animation.gif')
    sprite = pyglet.sprite.Sprite(animation, x=window.width//2, y=window.height//2)
    music.play()

    @window.event
    def on_draw():
        window.clear()
        label.draw()
        image.blit(50, 50)
        sprite.draw()

    @window.event
    def on_key_press(symbol, modifiers):
        if symbol == pyglet.window.key.Q:
            pyglet.app.exit()

    pyglet.app.run()
  

In this simple app, we have integrated text rendering, image display, sound playback, animations, and user input handling.
