PygameX 0.2

A library that improves pygame and makes it structured.

PyGameX

Description

An easy-to-learn library that makes Pygame more structured and user-friendly. The library has many built-in functions that simplify development at times.

Usage/Examples

Empty template

import PygameX as pygamex


class MainGame(Game):
    pass


MainGame(height=300, width=500, max_fps=60)

Simple game

import PygameX

from PygameX.game import *
from PygameX.all_objects import *

from random import randint


class MainGame(Game):
    background_color = color.BLUE
    object_render_mode = True

    def ready(self):
        player = Circle(
            position=(50, 50),
            radius=25,
            color=(0, 255, 0)
        )
        self.objects["player"] = player

    def on_event(self, event):
        super().on_event(event)

    def on_mouse_pressed(self, mouse):
        if mouse[1] == 1:
            if mouse[2]:
                player = self.objects["player"]
                if PygameX.math.is_point_inside_circle(mouse[0], player):
                    player.color = (randint(0, 255), randint(0, 255), randint(0, 255))

    def update(self):
        player = self.objects["player"]
        keys = PygameX.key.get_pressed()  # List of pressed keys
        if keys[PygameX.key.LEFT]:
            player.position = (player.position[0] - 3, player.position[1])
        if keys[PygameX.key.RIGHT]:
            player.position = (player.position[0] + 3, player.position[1])
        if keys[PygameX.key.UP]:
            player.position = (player.position[0], player.position[1] - 3)
        if keys[PygameX.key.DOWN]:
            player.position = (player.position[0], player.position[1] + 3)

Parameter	Type	Description
mouse	tuple	An immutable list containing the position: tuple, pressed key: pygame key, is pressed: boolean

Object render mode

PygameX adds the ability to use objects instead of manually drawing shapes.

To enable this mode, just set object_render_mode to True in your game class.

object_render_mode = True

All that remains to be done is to add objects to the objects dictionary.

Object

Object is the main class of all objects in PygameX, it is usually not used in games because it is a dummy that exists to create other objects such as line, circle, rect.

It has a render function for displaying an object on the game screen.

Rect

The object inheriting the Object having 3 settings: position size color.

Initializing template:

Rect(
    position=(50,50),
    size=(25,25),
    color=(0,255,0)
)

Circle

The object inheriting the Object having 3 settings: position radius color.

Initializing template:

Circle(
    position=(50,50),
    radius=25,
    color=(0,255,0)
)

Line

The object inheriting the Object having 3 settings: point1 point2 color.

Initializing template:

Line(
    point1=(50,50),
    point2=(25,25),
    color=(0,255,0)
)

Creating your own object

Any objects should inherit Object because it contains the render function and is simply more convenient than creating a new class manually. As a result, the dummy of the new class will look like this:

import pygame
from .Object import Object

class MyCustomObject(Object):

    def __init__(self):
        pass
    
    def render(self, screen):
        pass

Let's add the variables position and color inside.

import pygame
from .Object import Object

class MyCustomObject(Object):

    position = (0,0)
    color = (0,0,0)
    
    def __init__(self, position: tuple = (0,0), color: tuple = (0,0,0)):
        self.position = position
        self.color = color
    
    def render(self, screen):
        pass

Now in the render method we will draw our object. In the example, a 50x50 square is simply drawn using our values.

import pygame
from .Object import Object

class MyCustomObject(Object):

    position = (0,0)
    color = (0,0,0)
    
    def __init__(self, position: tuple = (0,0), color: tuple = (0,0,0)):
        self.position = position
        self.color = color
    
    def render(self, screen):
        pygame.draw.rect(screen, self.color, (self.position, (50, 50)))

Now let's try out our object in the game. Let's replace the circle from the example above with our object First, let's save our script in MyCustomObject, and then import it into the game.

import PygameX

from PygameX.game import *
from .MyCustomObject import MyCustomObject  # I immediately import the object

from random import randint


class MainGame(Game):
    background_color = color.BLUE
    object_render_mode = True

    def ready(self):
        player = MyCustomObject(
            position=(50, 50),
            radius=25,
            color=(0, 255, 0)
        )
        self.objects["player"] = player

    def on_event(self, event):
        super().on_event(event)

    def on_mouse_pressed(self, mouse):
        if mouse[1] == 1:
            if mouse[2]:
                player = self.objects["player"]
                if PygameX.math.is_point_inside_circle(mouse[0], player):
                    player.color = (randint(0, 255), randint(0, 255), randint(0, 255))

    def update(self):
        player = self.objects["player"]
        keys = PygameX.key.get_pressed()
        if keys[PygameX.key.LEFT]:
            player.position = (player.position[0] - 3, player.position[1])
        if keys[PygameX.key.RIGHT]:
            player.position = (player.position[0] + 3, player.position[1])
        if keys[PygameX.key.UP]:
            player.position = (player.position[0], player.position[1] - 3)
        if keys[PygameX.key.DOWN]:
            player.position = (player.position[0], player.position[1] + 3)


MainGame(width=500, height=300, max_fps=60)

Scripts

The library provides a quick import of all objects from the library.

from PygameX.all_objects import *

If you don't need to import all the objects, you can import them individually.

from .objects.Rect import Rect # Rect
from .objects.Circle import Circle # Circle
from .objects.Line import Line # Line
from .objects.TextDisplay import TextDisplay # Text

Convenient functions

PygameX provides functions for working with objects quickly.

List of additional functions:

is_point_inside_circle(point: tuple, circle: Circle)

PygameX.math.is_point_inside_circle(mouse_position, my_circle)

is_point_inside_rect(point: tuple, rect: Rect)

PygameX.math.is_point_inside_rect(mouse_position, my_rect)

Installation

Install my library using pip in CMD or PyCharm Console:

pip install PygameX
