PygamePal

A library of classes and functions to support game development in Pygame

Usage

• pip install pygamepal

• Full example, using all pygamepal classes

Contents

• Game
• Input
• SpriteImage
• Camera
• Utility Functions

Game (create a game with minimal setup) -- Template // Example

self.size = (x, y)
self.caption = 'text'
self.icon = pygame.image.load('imageURL')
self.fps = x
self.gameTime

self.init()
self.update(gameTime)
self.draw()
self.quit()

Input -- Example

# create new instance
input = pygamepal.Input(longPressDuration=60)

# update() must be called once per frame
input.update(deltaTime=1)
input.isKeyDown(keycode)
input.isKeyPressed(keycode)
input.isKeyReleased(keycode)
input.getKeyDownDuration(keycode)
input.isKeyLongDown(keycode)
input.isKeyLongPressed(keycode)
input.getKeyLongPressPercentage(keycode)

SpriteImage -- Example

# create new instance
spriteImage = pygamepal.spriteImage()

# add one or more sprites, associated with a state
spriteImage.addTextures(firstTexture, *moreTextures, state=None, animationDelay=12, loop=True, hFlip=False, vFlip=False)

# update() must be called once per frame
spriteImage.update()

# draw the current image/animation frame
spriteImage.draw()

# change the current image/animation state
# (does not need to be called for sprite with single state)
spriteImage.setState(state)

# resets the current animation
spriteImage.reset()

spriteImage.pause

Camera -- Example

# creates a new camera instance
camera = pygamepal.Camera(position=(0, 0), size=(640, 480), target=(0, 0), zoom=1, backgroundColour='gray30', borderColour='black', borderThickness=2, clamp=False, clampRect=(0, 0, 1000, 1000), followDelay=0)

# update() must be called once per frame
camera.update(deltaTime=1)

# draws surface to the destinationSurface, using camera attributes
camera.draw(surface, destinationSurface)

Utility functions

# draws text with minimal required parameters
drawText(screen, text, x, y, font=None, antialias=True, color=White, background=None)
# minimal example:
drawText(screen, 'Hello, world!')

# returns a list of sub-textures from a large spritesheet/texture
# the list has the same dimensions as the original texture, but
# can be flattened using flatten(2dList).
splitTexture(texture, newTextureWidth, newTextureHeight)
# simple example, splitting a single 96x32 spritesheet into 4 separate textures:
textureList = splitTexture(texture, 32, 32)
firstTexture = textureList[0][0] # or firstTexture = flatten(textureList)[0]

# flattens a 2d list into a single list
newList = flatten(2dList)
# see above for example
