The Beacon Captcha system is a poorly-created script I made in March of 2020 as a partial solution to the onslaught of "server-list" bots. This is not a fully-fledged captcha solution, but it should stop some automated processes.

_____________________________________________________



Demonstration of the Beacon Captcha in action.

If a player has not yet solved the Beacon Captcha, they will be prompted to solve it when attempting to chat or executing a command. They must click on each block that doesn't match with the beacon "tower" until all four stages have been completed. On the final stage, the player must click the beacon block itself to complete the captcha. The player is then granted the ability to speak in chat and execute in-game commands.

After failing or passing the captcha, the player will be presented with an animated success/failure screen that can be exited by clicking on any of the tiles in the GUI.



Still images of the animated success/failure screens.

Permissions:

- beacon.use - Used for /beacon's test commands.
- beacon.bypass - Bypasses the need to use the captcha entirely.

Commands:

- /beacon [var/test/fail/correct/clear]:

"Var" manually scrambles the Beacon Captcha's block patterns. (i.e. if the beacon's blocks were iron and redstone, it'd be randomized to something completely different. By default, this is automatically scrambled every 5 minutes, but the time between scrambles can be edited in the options section of this script.)

"Test" opens up the Beacon Captcha. This does not grant, nor does it revoke the ability to speak in chat/execute in-game commands.

"Fail" shows the Beacon Captcha's animated "failure" screen.

Likewise, "Correct" shows the Beacon Captcha's animated "success" screen.

"Clear" deletes the command sender's Beacon Captcha data. This forces them to complete the Beacon Captcha again.

This script comes with an options menu that allows you to easily edit all of the script's messages and some of its functions.
