Random Event Games are a type of game that enhances the game experience by generating unpredictable events. In such games, players must deal with random occurrences that may affect their resources, character status, or game progression. Such game design can increase replay value and unpredictability, making every gaming experience unique.
In this blog post, we will use Python to develop a text version of the random event game. Through this project, readers can not only learn how to build a random event game, but also master a variety of skills in Python programming, including object-oriented programming, data management, and logic design.
Let’s embark on this adventure full of surprises and challenges together and experience a random world of events built with code!
Project Overview
2.1 Game concept
Random Adventure is a text-based random event game where players will play an adventurer in an unknown world. Players need to deal with randomly generated events, manage resources and character status, and make decisions to continue their adventure.
Events in the game can be positive (such as finding treasures) or negative (such as encountering monster attacks), which will have an important impact on player choices and resource management. Players need to make the best choices in a changing environment to ensure survival and success.
2.2 Game Features
- Random Event System: Various events will be generated randomly in the game to increase unpredictability.
- Simple and easy-to-understand operation: interact with players through a text interface, intuitive and easy to understand.
- Resource Management: Players need to manage health, energy, items and other resources.
- Mission system: Set main and side tasks to increase game goals.
- Role Growth: Influencing character abilities by completing tasks and events.
2.3 Target player group
This game is suitable for the following players:
- Players who love adventure and exploration
- Players interested in random events and strategic decisions
- Players who like challenge and survival games
- Players seeking a relaxing and fun gaming experience
Technical selection and environmental preparation
3.1 Development Environment
This project is developed using Python 3.8+, and the following development tools are recommended:
- IDE: Visual Studio Code or PyCharm
- Terminal: Terminal that supports ANSI colors (such as Windows Terminal or PowerShell)
3.2 Dependency library
We will use the Python standard library and introduce a small number of third-party libraries to enhance the gaming experience:
- Basic library:
- random: used to generate random events
- time: used to control game rhythm and event time passage
- json: for archive and read
- os: for file and directory management
- Third-party library (optional):
- colorama: used for color display of command line text
- tabulate: Used to print formatted table
Install third-party libraries (on the command line):
pip install colorama tabulate
Game Design
4.1 The core game mechanism
The core mechanism of the game includes the following parts:
- Initialize the game: Set the player character, initial resources, and background.
- Turn-based loop:
- Displays the current status (such as health, energy, items).
- Randomly generate events and display them to the player.
- Players choose actions (respond to events, manage resources).
- Process the results of player selection and advance the game process.
- Random Events: Add random events to the game, increasing changes and unpredictability.
4.2 Game background
The game is set in a fantasy and mysterious world, and players will explore various areas, including forests, mountains, towns, etc. During the exploration process, players will encounter different random events that will affect their resources and decisions.
4.3 Roles and Resources
The characters and resources in the game will be the basis for players' actions. It mainly includes the following contents:
- Role:
- Player: The character played by the player has initial attributes.
- NPC: Non-player character, may provide quests or information.
- resource:
- Health value: reflects the player's survival status and affects the player's movement ability.
- Energy value: The energy required to perform an action, affecting the player's behavior frequency.
- Items: Props that players can collect and use, such as food, potions, etc.
4.4 Random Event System
The random event system is the core part of the game, and players will face various random events, and the occurrence of these events will be generated based on preset probability. Main functions include:
- Event generation: Generate different types of events through random numbers, such as encountering monsters, discovering treasures, shortage of resources, etc.
- Event handling: Adjust the player's status and resources according to the event type and player's choice.
4.5 Task and Achievement System
The mission system provides the game with goals, and players can get rewards by completing tasks and improve their character abilities. At the same time, the achievement system records players' achievements and inspires players to explore and challenge.
- Main mission: The main task to promote the development of the game story.
- Side Quests: Additional Quests, providing additional rewards and challenges.

The main loop of the game controls the interaction between the game's progress and the player:
def main():
game_engine = GameEngine()
player_name = input("Please enter your name:")
game_engine.start_new_game(player_name)
while game_engine.game_running:
game_engine.main_loop()
print("Thanks for playing Random Adventure!")
if __name__ == "__main__":
main()Detailed explanation of key functions
6.1 Game Initialization
When initializing the game, create players and set initial resources and backgrounds. JSON files can be used when loading data, making tasks and events more flexible.
6.2 Game main loop
The main loop of the game is responsible for handling player input and updates to game status. Players can choose to explore, complete tasks or exit the game in each turn.
6.3 Player Management
Players can manage through commands, selecting different strategies to deal with various random events.
6.4 Random Event Processing
Random event processing is the core part of the game, and players need to make decisions based on the event type. For example, when encountering monsters, players can choose to fight or run away; when discovering treasures, players can choose to view or ignore them.
6.5 Task system
The mission system allows players to complete specific goals to obtain rewards and enhance abilities. Mission completion will affect character status and game progress.
Game experience optimization
7.1 Text interface beautification
Use the colorama library to add colors to the game's output, making the game interface more beautiful and easy to read. Different colors can be added when outputting text to make keyword or character names stand out.
7.2 Game balance adjustment
Adjust the game difficulty according to the test results, including the speed of change in health, energy, frequency of events, etc., to ensure that the game is both challenging and not frustrating.
7.3 Progress Saving and Reading
An archive system is designed to allow players to save progress at any time in the game and continue the game next time. You can use JSON files to store the player's status, including character attributes, current resources, and completed tasks.
Extended features
8.1 Multiple Ending Design
Design multiple endings based on the player's choices, so that the player's choices directly affect the game's results and increase the game's replay value. For example, player decisions and event handling will affect the final victory conditions.
8.2 Custom role creation
Allows players to customize the character's attributes and background when starting the game, increasing the personalized experience of the game. A character customization option is available at the beginning, allowing players to choose their profession and skills.
8.3 Random Events and Story Development
Design a random event system to increase the occurrence of unexpected events during the game, such as task failures, item losses, etc., to improve the diversity and unpredictability of the game.
