pygrille 0.2.1

A quick way to write and visualise any code involving grids of squares in python.

Pygrille

Pygrille is a Python library that uses Pygame to make it easier to do many things involving a square grid.

Installation

Use the package manager pip to install Pygrille.

pip install pygrille

Usage

import pygrille

PIXEL_SIZE = 40 # The size of each square in the grid.
GRID_DIMENSIONS = (6, 5) # The number of squares in the x and y directions in the grid.

# Initiate the grid. PIXEL_SIZE and GRID_DIMENSIONS are required and everything else is optional. 
# The extras variable is a list of values that you want contained in each pixel - for example a temporary distance in Dijkstra's algorithm.
grid = pygrille.Grid(PIXEL_SIZE, GRID_DIMENSIONS, extras = ["Hello", "World"], framerate = 60, default_colour = pygrille.random_colour(), border_width = 10)

# Ensures the grid has not been closed each frame. 
# Also updates the newclick and newkey variables (booleans - True if there is a new click or key press) 
# And the lastclick (tuple - grid location of most recent click) and lastkey (string - name of most recent key pressed) variables.
while grid.check_open():

    # If the user clicks on a square, set it to a random colour and set the border to a random colour.
    if grid.newclick:
        grid[grid.lastclick[0]][grid.lastclick[1]].colour = pygrille.random_colour()
        grid[grid.lastclick[0]][grid.lastclick[1]].extras["Hello"] = "Clicked"
        grid.border_colour = pygrille.random_colour()

    # If the spacebar is pressed, print the status of the extra value "Hello" in the top left pixel.
    if grid.newkey:
        if grid.lastkey == "space":
            print(grid[0][0].extras["Hello"])

    # Draw the grid to the screen
    grid.draw()

    # Keep the grid running.
    grid.tick()

# Once pygrille is closed, finish quitting it.
grid.quit()
