goopylib 2.1.0

A powerful game, graphics, and application development library for Python

---

What is it?

goopylib is powerful game, graphics, and GUI library for Python and C++ to build cross-platform applications. It allows you to unlock the potential of OpenGL and low-level graphics with a high-level, simple-yet-powerful API.

Key Features:

• Cross-Platform & Powerful
• Fast! Built-in batch-rendering & optimizations
• Accessible through Python & C++
• Simple code to create, transform, & animate images, quads, triangles, circles, and more
• Automatic 2D Orthographic Camera & Camera Controller
• Window & Mouse events: key & button presses, several callbacks, etc.

In Development:

• Text Rendering
• GUI Elements
• Animation Engine
• Texture Factory
• Low-Level API Access

Future Plans:

• 2D Rigid-Body Physics Engine
• Sound & Lighting Engine
• Profiling Tools
• Build & Distribution Tools

Examples

Brick Breaker:

Conway's Game of Life:

Installation

Requires Python ≥ 3.8. To install goopylib on Windows or MacOS, use the Python Package Index (PyPI):

pip install goopylib

Wheels for Linux are not currently supported but coming as soon as I can build them!

Tutorial

Let's start by creating a rectangle on an empty window:

import goopylib as gp

window = gp.Window(700, 500)  # width=700, height=500

# centered at (0, 0), width=100, height=50
rect = gp.Rectangle((0, 0), 100, 50).draw(window)

while window.is_open():
    gp.update()

Inside the loop, you can check for events (or define callbacks instead):

while window.is_open():
    if window.check_key(gp.KEY_H):
        rect.hide()
    elif window.check_key(gp.KEY_S):
        rect.show()
    
    mousex, mousey = window.get_mouse_position()
    
    if rect.contains(mousex, mousey):
        print("Hovering over the rectangle!")
        
    gp.update()

Draw other shapes or more complex objects:

img = gp.Image("filepath.png", (0, 0)).draw(window)

Install a simple camera controller that automatically moves, rotates, and zooms in & out!

controller = gp.CameraController(window)

while window.is_open():
    # ...
    controller.update()
