How to prevent X-Ray on a Minecraft Server

X-ray in Minecraft refers to third-party modifications or texture packs that allow players to see through solid objects, revealing valuable resources such as ores or caves. This practice is considered cheating and is against the terms of service of most Minecraft servers, as it undermines the game's intended exploration and resource-gathering mechanics. Server administrators often implement anti-x-ray plugins or measures to detect and prevent players from using such cheats, ensuring fair and balanced gameplay for all participants.

Note: This IS NOT a full-proof method, as there are alternative plugins and ways for players to use X-Ray.

Note: An FTP client is required to transfer files onto the Minecraft server. Follow this tutorial to learn how to use an FTP client.
