Welcome to another one command creation! This one is meant for servers, but anyone can use it if they'd like. Let's jump into it!

What is this command creation?
This command creation adds no build/break zones for your Minecraft world. It will put any players who are not admins into adventure mode when inside the no build zone. What's even cooler is that it will return those players to their gamemode that they were in when they entered the no build zone.

How do I become an admin?
To become an admin, you can click on the link in the book provided by the command creation. If you don't want anyone else to be able to access this book though, you can run the following command: "/scoreboard players tag [PLAYERNAME] add Admin".

How do I demote an admin?
To remove someone's admin status, run the following command: "/scoreboard players tag [PLAYERNAME] remove Admin". In the [PLAYERNAME] blank, fill in the username of the player who you wish to demote.

How do I place or remove no build zones?
It's easy! Just make sure you're an admin so you won't run into any problems. Start by opening your no build zone manual and navigating to the "Get Items" page. Click on both the "[Spawn No Build Zones]" and the "[Spawn No Build Zone Remover]" to get the spawn eggs. Spawn a no build zone. The command creation should do the rest. If you want to remove the no build zone, spawn the "Spawn No Build Zone Remover" egg on the same block as the no build zone is located. When holding either of the spawn eggs, the no build zones will be revealed.

What if a non-admin gets a no build zone or no build zone remover spawn egg?
If a non-admin gets either of those spawn eggs, they will automatically be removed and have a message saying that they're not allowed to have those spawn eggs.

What if a non-admin gets a no build zone manual?
It depends. If you don't want that player to be an admin, keep the book away from them! Now, they could only become an admin if they also have their cheats enabled, but I'd still be careful about who gets the book.

What is the "Obtain Book Command Block" mentioned in the manual?
That's a command block you can get. The command block has the command you need to obtain a book. If you place down that command block and activate it, you will get a manual.

Warning! Item frames and paintings will still be editable for non-Admin players.
