Nemu - Text Adventure Engine

A complete text-based adventure game framework in Rust. Create, play, and share interactive stories with rich narratives and inventory systems.

Quick Start

1. Build the project:

   cargo build --release

2. Create a new adventure:

   ./target/release/nemu create my_adventure

3. Play the adventure:

   ./target/release/nemu play my_adventure/my_adventure.toml

4. Try in-game commands like:

   • look - examine your surroundings
   • go north - move in a direction
   • take key - pick up items
   • inventory - check your items

Features

• Room-based navigation with text descriptions and atmospheric details
• Inventory system with item combinations and usage mechanics
• Save/load game states with multiple slots and quick save/load
• Natural language command parsing
• Story files in TOML format with scripting capabilities
• Complex branching narratives with flags and conditions

Installation

Prerequisites

• Rust (latest stable)

Build from Source

# Clone the repository
git clone https://github.com/yourusername/nemu.git
cd nemu

# Build the project
cargo build --release

# The binary will be available as 'nemu' in target/release/

Usage

Available Commands

# Create a new story template
./target/release/nemu create my-adventure

# Validate a story file
./target/release/nemu validate my-adventure.toml

# Play a story
./target/release/nemu play my-adventure.toml

In-Game Commands

Once playing a story, use these commands:

• look - Look around the current room
• go [direction] - Move in a direction (north, south, east, west)
• n/s/e/w - Short forms for directions
• take [item] - Pick up an item
• drop [item] - Drop an item
• inventory - Check your inventory
• help - Show available commands
• quit - Exit the game

Story Format

Stories are written in TOML format. Here's an example:

[story]
title = "The Mysterious Forest"
start_room = "forest_entrance"

[rooms.forest_entrance]
title = "Dark Forest Entrance"
description = "You stand at the edge of a dark forest. Ancient trees loom overhead."
exits = { north = "deep_forest", east = "clearing" }
items = ["stick"]

[rooms.deep_forest]
title = "Deep in the Forest"
description = "Thick branches block most sunlight. You hear mysterious sounds."
exits = { south = "forest_entrance" }
items = ["mushroom", "berries"]

[items.stick]
name = "wooden stick"
description = "A sturdy stick that might be useful."

[items.mushroom]
name = "strange mushroom"
description = "A glowing mushroom that seems to pulse with light."

[items.berries]
name = "red berries"
description = "Small red berries that smell sweet."

Quick Start Example

1. Create a new story:

   cargo run -- create my_adventure

2. Look at the generated story:

   cat my_adventure/my_adventure.toml

3. Play the story:

   cargo run -- play my_adventure/my_adventure.toml

4. In the game, try:

   • look - to see your surroundings
   • go north - to move to another room
   • take key - to pick up an item
   • inventory - to see what you're carrying
