Pyglet Starter

import pyglet
from pyglet.shapes import Rectangle

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

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

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

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

# Start the application
pyglet.app.run()

To enhance the simple Pyglet game so that clicking on the rectangle increments and displays a counter on the game window, we need to add a few more features. We’ll handle mouse click events, check if the click is within the rectangle’s bounds, and then update and display a counter accordingly.

Updated Python Script for the Simple Game with Click Interaction

import pyglet
from pyglet.shapes import Rectangle
from pyglet.text import Label

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

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

# Initialize a counter
counter = 0

# Create a label to display the counter
counter_label = Label(f'Count: {counter}', font_size=18, x=window.width // 2, y=window.height - 30, anchor_x='center')

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

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

@window.event
def on_mouse_press(x, y, button, modifiers):
    # Check if the click is within the rectangle's bounds
    if (rect.x <= x <= rect.x + rect.width) and (rect.y <= y <= rect.y + rect.height):
        global counter
        counter += 1  # Increment the counter
        counter_label.text = f'Count: {counter}'  # Update the label text

# Start the application
pyglet.app.run()

Explanation of the Updated Features

1. Label for Displaying the Counter:

• We import Label from pyglet.text to create a text label.
• counter_label is initialized with a starting text that displays the counter. It is positioned at the top center of the window.

1. Handling Mouse Clicks:

• The on_mouse_press function is added to handle mouse click events. It receives parameters x and y which are the coordinates of the mouse click, and button and modifiers which provide additional information about which mouse button was clicked and whether any keyboard modifiers were held down.
• Inside this function, there’s a check to determine if the click occurred within the bounds of the rectangle. This is done by comparing the click coordinates x and y with the rectangle’s position and dimensions.
• If the click is within the rectangle, the counter is incremented and the label text is updated to reflect the new count.

Running the Updated Game

With these changes, clicking on the rectangle in the game window will increment a counter displayed at the top of the window. This simple interaction introduces you to handling mouse events and updating visual elements based on user interactions, which are common tasks in game development.

Make sure you have Pyglet installed and run this script in a Python environment. This example will help you understand basic event handling and display updates in Pyglet, which you can build upon for more complex game functionalities.
