gameEngine

A game engine built using pygame based off of the Unity game engine.

Installation

1: Use the package manager pip to install pygame.

pip install pygame

2: Go to variables.py and make a screen object

go below to see examples of how to do this

Save the screen as "screen"

3: Initialize all the game objects you want underneath the screen in variables.py

To set attributes for user-made scripts call the game object from the dictionary then follow the path to the attribute

4: Load all media(images, sound, etc) into the "data" folder

5: Write the main game code into ".py" files in the "scripts/user" folder

there are two folders in scripts; "user" and "builtins" you only need to look at user

a sample file is provided in the script/user folder already

make sure to load all the packages you want by naming the file and class name at the end of the game object declaration

6: Finally run the "main.py" file to run the game

The following should appear:

Code Samples

variables.py

from game_object import GameObject as GO
from screen_init import ScreenInit

# Creates a screen to run the game on
# screen = Init(width, height, fps, ffps, icon, name_window)
screen = Init(300, 280, 60, 100, "test.png", "myGame")

# initializes a game object onto the game screen
#loads in the script "Transform" to allow the go to be rendered on the screen and moved
#"origin" is the default parent
GameObject(name ,screen, sprite, parent, packages)
GameObject("test_object" ,screen.screen, "test.png", "origin", "Transform.transform")

#setting the attributes
GO.GAME_OBJECTS["test_object"].Transform.transform = [0,0]
GO.GAME_OBJECTS["test_object"].Transform.rotation = 0

player_movement.py

from game_object import GameObject

class PlayerMovement:
    def __init__(self, game_object):
        self.game_object = game_object
    def fixed_update(self):
        '''Every physics frame rotate the image by 1 degree and multiply the scale by 0.999'''
        self.game_object.Transform.rotation = self.game_object.Transform.rotation - 1
        self.game_object.Transform.scale = [self.game_object.Transform.scale[0] * 0.999, self.game_object.Transform.scale[1] * 0.999]

    #notice there is no update you do not need all the methods overriden in the player made scripts for it to run properly
if __name__ == '__main__':
    pass
