About this Mod

Simple Captcha Mod

SimpleCaptcha is a Minecraft mod designed for entertainment purposes, adding a playful twist to interactions by introducing captcha challenges as pranks. This mod is perfect for Minecraft players and server admins who want to inject a bit of fun and surprise into their gameplay.

Disclaimer

This mod is intended for joke purposes only and should not be used as a security measure. It is designed to add a fun and non-disruptive challenge for players, not to protect servers from bots or unauthorized access.

The mod was inspired by a video I saw on the SDMP server, I couldn’t find the mod so I assumed it was custom made and wanted to have it on my server so I recreated it.

The sounds were taken from The Graveyard Mod because idk where to get good sounds like that, if the owner would like me to remove please let me know.

Features

  • Captcha Challenge: Pops up a captcha challenge that must be solved to continue. These captchas are meant to be fun and slightly challenging, ensuring a humorous interruption in gameplay.

Commands

SimpleCaptcha introduces two primary commands to control when and to whom captchas appear:

  • /captcha: Triggers a captcha challenge for the player executing the command. Ideal for self-induced pranks.

  • /captcha [player]: Triggers a captcha challenge to the specified player. This allows for an element of surprise to other players' gameplay.

Requirements

Installation

To install SimpleCaptcha, follow these simple steps:

  1. Download the SimpleCaptcha mod file from the releases section.
  2. Place the downloaded .jar file into your Minecraft's mods folder.
  3. Ensure you are running a compatible version of Minecraft with the Fabric mod loader installed.
  4. Start your Minecraft client or server to see if the mod is loaded and ready for some prank action.

Usage

Initiating a Self-Challenge

To initiate a captcha challenge for yourself, type the following command in the game's chat:

/captcha

Sending a Challenge to Another Player

To send a captcha challenge to another player, use the command with their username:

/captcha username

Replace username with the actual player's name to surprise them with a captcha challenge.

Frequently Asked Questions

Simple Captcha server crashes on startup – what to do?

Is Simple Captcha compatible with fabric and forge and neoforge?

Simple Captcha officially supports fabric, forge, neoforge for Minecraft 1.21.8, 1.21.1, 1.21. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Simple Captcha – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Simple Captcha consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
