This package is made to fast prototype your multimedia applications like games on pygame. Write clean and pragmatic design. It lets you focus on the game engine itself, so you don't have to take care about several details like setting up the window, loading and checking data (images, sound, font, fx, music, resources names...). All you need to do is to put your resources into a specific data folder and use them in your game class 'MyEngine()'.

You don't need to reinvent the wheel, some repetitive parts of code (main loop, getting the delta time, closing the window, drawing text...) are already described and ready to use in the default engine.

Usage example :

  • Template main file

.. code-block:: python

from laylib import Environment
from engine import Engine
import sys

def main():
demo = Environment(800, 600, False, 'My game')
demo.load_complete(Engine(), 'data')
demo.gInstance.main_loop()
demo.destroy()

if __name__ == "__main__":
sys.exit(main())
  • Template engine file

.. code-block:: python

import pygame as pg
from laylib import DefaultEngine

BLACK = (0, 0, 0)
FPS = 30.0


class Engine(DefaultEngine):
	""" Short summary.
	"""

	def __init__(self):
		super().__init__()
		self.setup()

	def update(self):
		""" Code to update all classes : 
		the global behavior should be written here.
		"""
		pass

	def draw(self):
		self.screen.fill(BLACK)
		""" Code to draw all classes
		"""
		pg.display.update()

	# init engine or set up environement

	def setup(self):
		self.playing = True
		# rescale in laylib time unit to 100.0 as example
		self.time_unit = 100.0
		self.fps = FPS
		"""
		rest of init code
		"""

INSTALLATION

First, install the dependencies:

.. code-block:: bash

$ pip install -r requirements.txt

Then install laylib:

.. code-block:: bash

$ pip install laylib

Or alternatively, you can just copy the "laylib" folder into the same directory as the Python program that uses it.

USAGE

For usage see examples provided with laylib. For more details, all other parts of documentation are described in the source file.
