How Player Tracking Works

The system parses the server log in real-time to detect:

1. Player Joins: Player connected: PlayerName, xuid: ...
2. Player Leaves: Player disconnected: PlayerName, xuid: ...
3. List Command: There are X out of maximum Y players online: Player1, Player2, ...

Smart Parameter Detection

When you type a command, the system checks if the current parameter accepts player names:

• Commands with player parameters: kick, ban, op, deop, give, clear, effect, xp, tp, teleport, gamemode, title, etc.
• Shows player suggestions: Only when typing the player name portion
• Keyboard navigation: Arrow keys to select, Tab/Enter to insert

Example Usage

Type: kick <space>
Result: Shows dropdown with all online players

Type: kick St
Result: Filters to players starting with "St" (e.g., Steve, Steve123)

Select: Use arrow keys or mouse, press Tab/Enter
Result: "kick Steve " (ready for optional reason parameter)
