Hi everyone. I am making a mod where there is a block that can "mask" itself so that people can't find it. However, I cannot seem to get the code to work, no matter how hard I try. I have tried a


, however this wouldn't work, I also have tried storing the blockstate and simply returning the blockstate in the tileentity in




, but nothing works. I don't understand why. A little help would help me greatly.

Hi! I'm a Java programmer but barely know anything Minecraft related.

You don't need TEs or TESRs for this, is possible with blockstates.


Take a look at GreyGhosts's Minecraft By Example mod:

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.
