Creating a Simple Game with PyCharm and Pyglet: A Step-by-Step Guide

If you’re interested in game development with Python, Pyglet is an excellent library to start with. It’s a cross-platform windowing and multimedia library for Python, ideal for creating games and other visually rich applications. In this tutorial, we’ll walk through the process of creating a simple game using PyCharm, a popular Python IDE, and Pyglet.

Step 1: Setting Up PyCharm

Before we begin, you need to have PyCharm installed. If you haven’t installed PyCharm yet, you can download it from JetBrains. Choose the Community Edition, which is free.

Installing Pyglet in PyCharm:

1. Open PyCharm and create a new project by selecting File > New Project.
2. In the new project setup window, specify your project name and location. Make sure the selected interpreter is Python 3, which you should have previously installed on your system.
3. Once the project is created, open the terminal in PyCharm (usually at the bottom of the IDE) and install Pyglet by running:

   pip install pyglet

Step 2: Creating Your Game Window

Let’s start by setting up a basic window using Pyglet:

1. Create a new Python file in your project by right-clicking on the project directory, then New > Python File. Name it main.py.
2. Open main.py and write the following code:

   import pyglet

   # Create a window
   window = pyglet.window.Window(width=800, height=600, caption='My Game')

   @window.event
   def on_draw():
       window.clear()
       # Here you can draw objects or handle other graphical elements

   # Start the application
   pyglet.app.run()

This code sets up a window using Pyglet with a width of 800 pixels and height of 600 pixels. The on_draw event is connected to the window, which clears the window each time it needs to be redrawn.

Step 3: Adding a Simple Game Element

Next, let’s add a simple graphical element, such as a rectangle, that moves across the screen:

1. At the top of your main.py, add the following import:

   from pyglet.shapes import Rectangle

2. Before the pyglet.app.run() line, add the following lines to create a rectangle:

   # Create a rectangle
   rect = Rectangle(x=50, y=50, width=200, height=100, color=(50, 225, 30))

3. Modify the on_draw() function to draw the rectangle each time the window is redrawn:

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

Step 4: Making the Rectangle Move

To make the game interactive, let’s make the rectangle move when the right arrow key is pressed:

1. Define an on_key_press event to handle keyboard input:

   @window.event
   def on_key_press(symbol, modifiers):
       if symbol == pyglet.window.key.RIGHT:
           rect.x += 10  # Move the rectangle to the right

This setup uses Pyglet’s built-in keyboard constants to check if the right arrow key is pressed, then moves the rectangle 10 pixels to the right.

Step 5: Running Your Game

• Save all changes in PyCharm.
• Run main.py by right-clicking the file in PyCharm and selecting Run 'main'.
• A window should open displaying your moving rectangle. Press the right arrow key to see it move.

Conclusion

Congratulations! You’ve just created a basic game framework using PyCharm and Pyglet. This setup can serve as a foundation for more complex games by incorporating additional elements like more shapes, collision detection, sounds, and more interactive features. Experiment with Pyglet’s capabilities to expand your game further. Enjoy coding and game development with Python!
