# In-Game Commands

In-game chat commands for players and administrators.

> **Looking for player documentation?** See [Player Commands Reference](player-commands.md) for a user-friendly guide to using commands in-game.

## Configuration

```json
{
  "Commands": {
    "Enabled": true,
    "CommandPrefix": "!",
    "Reload": { "Enabled": true, "Prefix": "reload" },
    "Raviente": { "Enabled": true, "Prefix": "ravi" },
    "Course": { "Enabled": true, "Prefix": "course" },
    "Rights": { "Enabled": false, "Prefix": "rights" },
    "Teleport": { "Enabled": false, "Prefix": "tele" },
    "KeyQuest": { "Enabled": false, "Prefix": "kqf" },
    "Ban": { "Enabled": false, "Prefix": "ban" },
    "Help": { "Enabled": true, "Prefix": "help" },
    "PSN": { "Enabled": true, "Prefix": "psn" },
    "Discord": { "Enabled": true, "Prefix": "discord" },
    "Timer": { "Enabled": true, "Prefix": "timer" },
    "Playtime": { "Enabled": true, "Prefix": "playtime" }
  }
}
```

## How Commands Work

1. **Player Types Command**: Player sends a chat message starting with the command prefix
2. **Command Parser**: Server checks if message matches any enabled command prefix
3. **Command Handler**: Executes the command logic
4. **Response**: Server sends feedback message to the player

Commands are parsed in [handlers_cast_binary.go:90](../server/channelserver/handlers_cast_binary.go#L90).

## Available Commands

### Reload

**Prefix:** `!reload`
**Recommended:** Enabled
**Usage:** `!reload`

Server: "User ABC123 banned for 2 hours"
```

**⚠️ SECURITY WARNING:** Only enable for trusted administrators. Requires operator permissions.

## Command Configuration

Each command has three properties:

```json
{
  "Name": "CommandName",
  "Enabled": true,
  "Prefix": "!prefix"
}
```

| Property | Type | Description |
|----------|------|-------------|
| `Name` | string | Command identifier (must match internal name) |
| `Enabled` | boolean | Whether the command is active |
| `Prefix` | string | Chat prefix that triggers the command |

### Customizing Prefixes

You can change command prefixes:

```json
{
  "Name": "Reload",
  "Enabled": true,
  "Prefix": "/reload"
}
```

Now players would type `/reload` instead of `!reload`.

### Disabling Commands

Set `Enabled: false` to disable:

```json
{
  "Name": "Rights",
  "Enabled": false,
  "Prefix": "!rights"
}
```

When disabled, typing the command returns:

```text
Server: "The Rights command is disabled on this server"
```

## Security Considerations

### High-Risk Commands (Disable in Production)

- **Rights**: Grants admin privileges and all courses
- **KeyQuest**: Unlocks restricted content
- **Ban**: Can permanently remove players from server
- **Teleport**: Bypasses normal movement restrictions

### Medium-Risk Commands (Use with Caution)

- **Course**: Allows players to toggle courses without payment
  - Mitigate by limiting which courses are `Enabled` in [Courses](courses.md)

### Safe Commands

- **Reload**: Only affects visual state, no persistent changes
- **Raviente**: Only affects raid event, no account changes
- **Help**: Read-only, shows available commands
- **Timer**: User preference only, no gameplay impact
- **Playtime**: Read-only display
- **PSN**: Account linking, low risk
- **Discord**: Token generation, requires Discord bot to be useful

## Implementation Details

Commands are initialized on server startup from the config:

```go
// handlers_cast_binary.go:40
func init() {
    commands = make(map[string]config.Command)

    for _, cmd := range config.ErupeConfig.Commands {
        commands[cmd.Name] = cmd
        if cmd.Enabled {
            logger.Info(fmt.Sprintf("Command %s: Enabled, prefix: %s", cmd.Name, cmd.Prefix))
        }
    }
}
```

Each command handler checks if the command is enabled before executing.

## Examples
