## Installation Methods

### Method 1: Pre-built Releases (Recommended)

This is the easiest method for most users.

1. Visit the [Releases page](https://github.com/aerinon/ALttPDoorRandomizer/releases)
2. Download the appropriate build for your system:
   - **Windows**: `ALttPDoorRandomizer-{version}-windows.zip`
   - **macOS**: `ALttPDoorRandomizer-{version}-osx.tar.gz`
   - **Linux**: `ALttPDoorRandomizer-{version}-linux-focal.tar.gz`
3. Extract the archive to a folder of your choice
4. Run the executable:
   - **Windows**: `DungeonRandomizer.exe`
   - **macOS/Linux**: `./DungeonRandomizer` or `./Gui.py`

### Method 2: Running from Source

For developers or users who want to run the latest development version.

#### Step 1: Clone the Repository

```bash
git clone https://github.com/aerinon/ALttPDoorRandomizer.git
cd ALttPDoorRandomizer
```

For the development branch:
```bash
git checkout DoorDevUnstable
```

#### Step 2: Install Python Dependencies

The project includes a script to install platform-specific dependencies:

```bash
python resources/ci/common/local_install.py
```

This will install all necessary Python packages and platform-specific dependencies.

#### Step 3: Verify Installation

Test that everything is working:

```bash
python DungeonRandomizer.py --help
```

You should see the help text with all available options.

## Usage

### GUI (Graphical User Interface)

The GUI provides an easy-to-use interface for generating seeds.

#### Starting the GUI

**Pre-built release:**
- **Windows**: Double-click `DungeonRandomizer.exe`
- **macOS/Linux**: Run `./DungeonRandomizer` from terminal

**From source:**
```bash
python Gui.py
```

#### Using the GUI

1. **Select your ROM**: Click "Select ROM" and choose your ALttP ROM file
2. **Configure settings**: Use the tabs to adjust:
   - **Dungeon Settings**: Door shuffle mode, intensity, key logic
   - **Item Settings**: Item placement, shopsanity, pottery
   - **Entrance Settings**: Entrance randomization options
   - **Enemy Settings**: Enemy shuffle, boss shuffle
   - **Game Options**: MSU resume, collection rate, etc.
3. **Generate**: Click "Generate" to create your seed
4. **Output**: The patched ROM will be created in the same directory

### CLI (Command-Line Interface)

The CLI offers more control and is useful for batch generation or scripting.

#### Basic Usage

```bash
python DungeonRandomizer.py [options]
```

#### Common Examples

**Basic crossed dungeon shuffle:**
```bash
python DungeonRandomizer.py --doorShuffle crossed --intensity 2
```

**With key shuffle and shopsanity:**
```bash
python DungeonRandomizer.py --doorShuffle crossed --keyshuffle wild --shopsanity
```

**Pottery and enemy drops:**
```bash
python DungeonRandomizer.py --doorShuffle basic --pottery lottery --dropshuffle underworld
```

**Generate without creating ROM (testing):**
```bash
python DungeonRandomizer.py --suppress_rom --spoiler none
```

**Create BPS patch instead of ROM:**
```bash
python DungeonRandomizer.py --bps --doorShuffle crossed
```

**Batch generation:**
```bash
python DungeonRandomizer.py --doorShuffle crossed --count 10
```

## Multiworld Setup

Door Randomizer supports multiworld seeds where multiple players play different randomized games with shared item pools.

### Installing Multiworld Dependencies

Run the same installation script to install multiworld-specific dependencies:

```bash
python resources/ci/common/local_install.py
```

### Generating Multiworld Seeds

Create YAML files for each player (see `docs/player1.yml`, `docs/player2.yml`, `docs/player3.yml` for individual examples, or `docs/multi_mystery_example.yaml` for a complete multiworld configuration).

**Example player configuration:**
```yaml
description: Player 1's World
name: Player1
doorShuffle: crossed
intensity: 2
keyshuffle: wild
shopsanity: true
```

Generate the multiworld using the multi-mystery configuration file:
```bash
python DungeonRandomizer.py --customizer docs/multi_mystery_example.yaml
```

### Running Multiworld Server

```bash
python MultiServer.py
```

It will prompt you for the multidata file created from the multiworld generation step.

### Connecting with Multiworld Client

```bash
python MultiClient.py
```

Enter the server address and your player name to connect.

---

## Testing & Verification

### Running the Test Suite

To verify your installation and test the randomizer logic:

```bash
python TestSuite.py
```

**Test with specific settings:**
```bash
python TestSuite.py --dr basic --count 10 --tense 2
```

**Run specific test modules:**
```bash
python -m pytest test/
python -m pytest test/dungeons/TestDarkPalace.py
```

---

## Troubleshooting

### Common Issues

#### "Python not found" or "python: command not found"

- **Windows**: Make sure Python is installed and added to PATH during installation
- **macOS/Linux**: Install Python 3.10+ via your package manager or from [python.org](https://www.python.org/)

#### "No module named 'yaml'" or similar import errors

Run the dependency installation script:
```bash
python resources/ci/common/local_install.py
```

#### Pre-built executable won't run on macOS

macOS may block unsigned applications. Right-click the app and select "Open" to bypass the warning.

#### Pre-built executable won't run on Linux

Ensure the file has execute permissions:
```bash
chmod +x DungeonRandomizer
```

#### GUI window is too small or cut off

Try running from the command line to see if there are any error messages. Some display scaling settings can cause issues.

#### Generated ROM doesn't work with emulator

- Ensure you're using a clean US version of ALttP ROM (Japan 1.0)
- Try a different emulator (recommended: SNES9x, RetroArch with bsnes core)
- Verify the ROM was patched successfully (check file size and modification date)
