Usage:

1. Installation and Setup:
   • Place the downloaded PassiveWhitelist plugin JAR file into your server's plugins folder.
   • Start the server or run the /reload command.
2. Configuration:
   • The plugin uses a customizable configuration file located at plugins/PassiveWhitelist/config.yml. Below are the default settings:
     • question: "Evaluate the definite integral of four with respect to x, from zero to four."
     • answer: "16"
     • welcomeMessage: "Welcome! Please answer the following question to join the server:"
     • correctMessage: "Correct! You can now play on the server."
     • incorrectMessage: "Incorrect answer. Please try again."
     • kickMessage: "You didn’t respond within the time limit."
     • kickDelay: 3
     Each of these values can be customized to suit your server's needs. For example, you can change the question, correct answer, or time delay before unverified players are kicked.
3. Reload:
   • After modifying config.yml, use /pw reload to apply changes without restarting the server.

Commands:

• /pw reload: Reloads the plugin's config.yml dynamically.
• /pw revoke <player>: Revokes authentication for a player, requiring them to answer the question again.

Restrictions for Unverified Players:

Until a player answers the question correctly:

• Movement: Players are frozen in place.
• Interactions: Breaking/placing blocks, interacting with entities, and using items are disabled.
• Commands: All commands are blocked.
• Item Pickup and Drop: Players cannot pick up or drop items.
• Damage: Players cannot deal or receive damage.
• Vehicles: Players cannot enter boats, minecarts, or other vehicles.

Once the correct answer is provided, these restrictions are removed, and the player is permanently authenticated.
