Localization

• messages_en.yml – English
• messages_ru.yml – Русский

To add a new language:

Create a new file (e.g. messages_de.yml)

How It Works

On join, players must pass a captcha before interacting:

✅ Button Captcha: Click the correct colored button
✅ Math Captcha: Solve a simple math problem
✅ Freeze System: Prevents movement, chatting, or interaction

Restrictions:

Players can’t move (freeze)
Blocked from chat (except allowed commands)
No interaction with items, blocks, or entities

Success: Player is unfrozen, receives a success message and sound
Failure: Player is kicked after max-attempts or timeout

Protect your server from bots the smart way — with AdvancedCaptcha!
