Command line text RPG

In this Python command line text RPG (role playing game) video we make a simple text-based game where the player finds themselves in a dark dungeon and must choose between two doors. The objective is to choose the correct door that leads to a desirable outcome, such as finding treasure, while avoiding the dangerous outcome, such as encountering a monster.

Video summary

In the video write a single, simple Python script, and run it in PyCharm (you can use Visual Studio Code, too).

The script starts by importing the necessary modules: Python random for generating random events and Python time for adding pauses in the game.

There is a function print_pause that prints a message and adds a pause of 2 seconds for a better game experience.

The intro function presents the initial scenario to the player, describing the dark dungeon and the two doors. It prompts the player to choose between door "1" or door "2".

The choose_door function handles the player's choice. If the player chooses door "1", they find a room filled with gold and win the game. If the player chooses door "2", they are attacked by a monster. A random event occurs to determine the outcome: a 50% chance of defeating the monster and finding a hidden treasure, leading to victory, or a 50% chance of being defeated by the monster, resulting in game over. If the player enters an invalid input, they are prompted to try again.

The play_game function orchestrates the flow of the game by calling the intro function to set the initial scene and then calling the choose_door function to handle the player's choice.

Finally, the script executes the play_game function, starting the game and allowing the player to play and experience the outcomes based on their choices.

Complete script from the video

Here's the full Python script for the text RPG, from the video:

import random
import time


def print_pause(message):
    print(message)
    time.sleep(2)


def intro():
    print_pause("You find yourself in a dark dungeon.")
    print_pause("In front of you, there are two doors.")
    print_pause("One door leads to treasure, the other leads to danger.")
    print_pause("Which door do you choose (1 or 2)?")


def choose_door():
    door = input("Enter 1 or 2: ")
    if door == "1":
        print_pause("You open the door and find a room filled with gold!")
        print_pause("Congratulations! You win!")
    elif door == "2":
        print_pause("You open the door and are attacked by a monster!")
        if random.randint(0, 1) == 0:
            print_pause("You defeat the monster and find a hidden treasure!")
            print_pause("Congratulations! You win!")
        else:
            print_pause("The monster is too powerful! You are defeated! Game over.")
    else:
        print_pause("Invalid input. Try again.")
        choose_door()


def play_game():
    intro()

Learn Python game development

Here are some additional resources you might like to check out if you're interested in Python game development.

Pygame

If you're into game development, and want to take it a step further, you might want to check out Pygame. Pygame is a popular open-source library for Python that is specifically designed for game development and multimedia applications. It provides a powerful set of tools and functionalities that simplify the process of creating games and interactive applications.

Here's a comprehensive overview of Pygame:

Graphics and Rendering

Pygame allows developers to handle graphics and rendering efficiently. It provides a versatile surface module for creating and manipulating images, shapes, and animations. Developers can draw lines, circles, rectangles, and polygons, as well as apply transformations and blending effects to create visually appealing graphics.

Audio and Sound Effects

Pygame offers features for working with audio and sound effects. It supports loading and playing different audio file formats, such as WAV and MP3, enabling developers to incorporate background music, sound effects, and interactive audio elements into their games. Pygame also provides functions for controlling playback, adjusting volume, and implementing audio filters.

Input Handling

Pygame simplifies the process of handling user input. It provides functions to detect and respond to keyboard, mouse, and joystick events. Developers can easily capture keystrokes, mouse movements, mouse clicks, and joystick inputs, allowing for intuitive and responsive user interactions in games.

Collision Detection

Pygame offers built-in collision detection functions that help developers detect and handle collisions between game objects. This is crucial for implementing game mechanics like object interactions, character interactions, and obstacle avoidance. Pygame's collision detection capabilities enable developers to create dynamic and interactive game environments.

Event Handling

Pygame provides a comprehensive event handling system. It allows developers to respond to various events, such as keyboard and mouse inputs, window resizing, and system events. This system facilitates creating event-driven games and interactive applications where different actions are triggered based on user interactions and system events.

Sprite Handling

Pygame simplifies the management and manipulation of sprites, which are essential elements in 2D game development. It provides a sprite module that includes classes and functions for creating, animating, and controlling sprites. Developers can easily handle sprite movements, collisions, and animations, enabling the creation of dynamic and visually appealing game characters and objects.

Game Development Support

Pygame offers a range of features and utilities that support game development. These include functions for managing game loops, timing and frame rate control, managing game states and transitions, loading and saving game data, and handling fonts and text rendering. Pygame's built-in functionalities streamline the development process, allowing developers to focus on game design and logic.

Cross-Platform and Community Support

Pygame is designed to be cross-platform, meaning games developed with Pygame can be run on multiple operating systems, including Windows, macOS, and Linux. Pygame has an active and supportive community, with numerous online resources, tutorials, and examples available. This community support makes it easier for developers to get started with Pygame, troubleshoot issues, and find inspiration for their game projects.

In summary, Pygame is a powerful library for Python that simplifies game development and multimedia applications. Its rich set of features for graphics, audio, input handling, collision detection, and event management make it a popular choice among developers. Pygame's cross-platform compatibility and supportive community further contribute to its popularity as a game development tool.
