Designing the Game

Hey there, game designer! 🕹️ Imagine creating your own game where you decide what happens, how characters move, and how the story unfolds. Sounds fun, right? Today, we’ll design a simple game in Python, step by step. Think of it as crafting a magical world where anything is possible!

Step 1: What Game Are We Making?

Before we dive into code, let’s decide what we want to build. How about a treasure-hunting game? Here’s the idea:

• You’re an adventurer trying to find a hidden treasure.
• You can move around a grid.
• If you reach the treasure, you win!

Step 2: Planning the Game World

We’ll use a grid to represent our game world. Think of it like a checkerboard where each square is a location.

Code Example: Setting Up the Grid

# Define the game world as a 5x5 grid
grid_size = 5
treasure_position = (2, 3)  # The treasure is at row 2, column 3
player_position = (0, 0)    # Player starts at the top-left corner

Here’s how the grid looks:

(0, 0)   (0, 1)   (0, 2)   (0, 3)   (0, 4)
(1, 0)   (1, 1)   (1, 2)   (1, 3)   (1, 4)
(2, 0)   (2, 1)   (2, 2)   (2, 3)   (2, 4)
(3, 0)   (3, 1)   (3, 2)   (3, 3)   (3, 4)
(4, 0)   (4, 1)   (4, 2)   (4, 3)   (4, 4)

Step 3: Moving Around the Grid

The player will move up, down, left, or right.

Code Example: Player Movement

def move_player(position, direction):
    row, col = position
    if direction == "up" and row > 0:
        row -= 1
    elif direction == "down" and row < grid_size - 1:
        row += 1
    elif direction == "left" and col > 0:
        col -= 1
    elif direction == "right" and col < grid_size - 1:
        col += 1
    else:
        print("You can't move in that direction!")
    return (row, col)

# Example usage
player_position = move_player(player_position, "down")
print("Player is now at:", player_position)

Step 4: Checking for the Treasure

After every move, we check if the player found the treasure.

Code Example: Winning Condition

def check_treasure(player_position, treasure_position):
    if player_position == treasure_position:
        print("Congratulations! You found the treasure! 🎉")
        return True
    return False

# Example usage
if check_treasure(player_position, treasure_position):
    print("Game Over!")

Step 5: The Full Game Loop

Now let’s tie everything together with a game loop. This will keep running until the player finds the treasure.

Code Example: Complete Game

# Initial positions
player_position = (0, 0)

print("Welcome to the Treasure Hunt Game!")
print("Find the treasure hidden in the grid!")

# Game loop
while True:
    print(f"You are at position {player_position}")
    move = input("Enter your move (up, down, left, right): ").lower()
    player_position = move_player(player_position, move)

    if check_treasure(player_position, treasure_position):
        break

Practice Time! 🎮

Here are some challenges for you:

1. Add Obstacles: Place rocks in the grid that block the player’s movement.
   Hint: Use a list of obstacle positions and check before moving.
2. Add a Score: Track the number of moves the player takes to find the treasure.
3. Random Treasure Location: Change the game to place the treasure at a random position every time.

Solutions to Practice Challenges

1. Adding Obstacles

obstacles = [(1, 1), (3, 2)]

def move_player_with_obstacles(position, direction, obstacles):
    new_position = move_player(position, direction)
    if new_position in obstacles:
        print("Oops! There's a rock there. You can't move.")
        return position
    return new_position

player_position = move_player_with_obstacles(player_position, "down", obstacles)

2. Adding a Score

score = 0

while True:
    score += 1  # Increment score for each move
    print(f"Moves taken: {score}")
    ...

3. Random Treasure Location

import random

treasure_position = (random.randint(0, grid_size - 1), random.randint(0, grid_size - 1))
print("Treasure is hidden somewhere. Good luck!")

Now you’re a game designer! Keep experimenting, add fun features, and let your imagination run wild. 🕹️✨
