How to Develop a Classic Ludo Game in Python with Source Code

Develop Ludo Game in Python [Source Code Included]

Ludo is one of the most popular board games in the world. It is quite easy to learn and can be played by anyone. Developing a Ludo game using Python is a great way to hone your skills and become a better programmer. In this tutorial, we will go through the steps of creating a simple Ludo game, complete with source code.

Requirements

• Python 3
• Tkinter (for graphics)

Setup

First, we need to import the necessary modules and create our window:

from tkinter import *

root = Tk()
root.title("Ludo")
root.geometry("400x600")

The window will be 400 pixels wide and 600 pixels high, and we'll call it “Ludo”. Now, we need to set up the game board:

canvas = Canvas(root, width=400, height=400)
canvas.pack()

# Create board
square_size = 50
for i in range(0, 400, square_size):
    canvas.create_line(0, i, 400, i, fill="black")
    canvas.create_line(i, 0, i, 400, fill="black")

This will create the 8x8 grid of squares. We also need to add the pieces:

# Add pieces
player1_pieces = []
for i in range(1, 5):
    player1_pieces.append(canvas.create_oval(i*square_size-20, 0, i*square_size+20, 40, fill="red"))

player2_pieces = []
for i in range(1, 5):
    player2_pieces.append(canvas.create_oval(i*square_size-20, 360, i*square_size+20, 400, fill="blue"))

This will add the four pieces for each player. Now, we need to add the dice:

# Add dice
dice = canvas.create_rectangle(350, 450, 400, 500, fill="orange")
canvas.create_text(375, 475, text="Roll", font="Arial 15")

This will create a rectangle with a “Roll” button in the center. We also need to define some variables to keep track of the game state:

# Define game state variables
player1_turn = True
player1_score = 0
player2_score = 0
dice_roll = 0

Now, we need to write the code for rolling the dice and moving the pieces:

# Roll dice function
def roll_dice():
    global dice_roll, player1_turn

    dice_roll = random.randint(1, 6)
    canvas.itemconfigure(dice, text=str(dice_roll))

    if player1_turn:
        player1_turn = False
    else:
        player1_turn = True

# Move pieces function
def move_pieces():
    global player1_pieces, player2_pieces, dice_roll, player1_turn, player1_score, player2_score

    if player1_turn:
        # Move player 1 pieces
        for i in range(len(player1_pieces)):
            x1, y1, x2, y2 = canvas.coords(player1_pieces[i])
            if x2 + dice_roll * square_size <= 400:
                canvas.coords(player1_pieces[i], x1+dice_roll*square_size, y1, x2+dice_roll*square_size, y2)
            else:
                player1_score += 1
    else:
        # Move player 2 pieces
        for i in range(len(player2_pieces)):
            x1, y1, x2, y2 = canvas.coords(player2_pieces[i])
            if x2 + dice_roll * square_size <= 400:
                canvas.coords(player2_pieces[i], x1+dice_roll*square_size, y1, x2+dice_roll*square_size, y2)
            else:
                player2_score += 1

This code defines functions for rolling the dice and moving the pieces. Finally, we need to create the event handlers:

# Add event handlers
canvas.tag_bind(dice, "", roll_dice)
canvas.tag_bind(player1_pieces, "", move_pieces)
canvas.tag_bind(player2_pieces, "", move_pieces)

This will bind the mouse click event to the functions for rolling the dice and moving the pieces. Now, we can start the game loop:

# Start game
root.mainloop()

The game is now ready to play! You can find the full source code here.
