Demonstration 1

Orebfuscator - Anti X-RAY:

For all releases of 1.9/1.9.1/1.9.2/1.9.4: Version 4.0.14

Now with support for CraftBukkit 1.9/1.9.1/1.9.2/1.9.4!

This plugin is used to counter X-RAY Client mods.

It modifies data that are sent to clients to hide blocks of your choice, such as Ore, chests, dungeons, etc.

It does not manipulate blocks in the world file, thus is safe to use.

ProximityHider is a feature that hides chests that are far from players.

Latest version should be on BukkitDev, or as a release on the Github page: https://github.com/lishid/Orebfuscator/releases

    OK, thanks. And thanks for fixing the plugin. Regarding checking to see if it works, I was using World Edit's "super pickaxe" mode (which I gather bypasses some stuff) to dismantle a building, and when I destroyed the bottom layer, I saw a bunch of random ores. So it looks like the plugin is working.

    @Bobcat00: Go

    It was a new check they implemented that I did not see. It checks whether the chunk is ready for sending and processing.

    As for checking if it's working, you could test by setting InitialRadius to 0 to see any exposed stone turned to random ore. Remember to turn it back after you verify.

    Looks good! Just out of curiosity, what was the problem?

    Also, how can we tell the plugin is actually doing what it's supposed to? Or do we have to actually install an x-ray mod to see?

    Fixed all the problems with 1.7.2/1.7.4! This fixed the chunk generation issue with trees and houses being cut.

    This looks like a stable build!

    Are you guys running 2.0.4? That API error should be fixed in 2.0.4. You could always set CheckForUpdates false in the config file.
