Alot of users on my server have been downloading texture packs that leave all blocks invisible except rare ores (to give themselves an advantage over normal players). I thought of a simple idea to prevent this form of cheating that someone might be able to do easily and efficiently. Idea: -Find all rare ore locations, save them -Convert all rare ores to stone -If a player is within a certain radius of the rare block locations, change the stone back to the rare ore. -If the player leaves that location, convert back to stone. This way the rare ores would be invisible along with everything else in these cheat texture packs. Lemme know what you guys think.
