I am relatively new to command blocks. They are amazing and can do many things, and it would be amazing to add them to a server, however, I would not want them to be misused. So what I am wondering is if there is a way to create a designated "Command block area." Command blocks would be enabled in and only in that area. If a player wanted to experiment with command blocks, they could enter the area and do whatever they want, but the commands would not affect the rest of the world.
It seems pretty impossible to me, but if anyone could offer me any help, that would be awesome. Thank you in advance.
Well first of all, only opers can modify command blocks, so it might not be as effective as you would like. That aside, there is no real way to restrict the area a command block can modify, unless all the other chunks in the world are not loaded and you can't use the /spreadplayers command to load them. This may be possible with a mod, but not in vanilla.
Edit: You could, however, make another dimension allow command blocks as command blocks cannot so as much in another dimension. You can still target players/entities, but not modify the world. You can summon entities in other dimensions though. Then you could setup some command blocks that will clear any command blocks from a player when they enter a dimension where they are not allowed.
The dimension idea sounds like a good idea. I shall experiment with it. Thanks for the idea!
Just keep in mind, someone could make a nether chunk loader by sending an item through a portal from the overworld every 60 seconds (not sure of the exact time it stays loaded off the top of my head) so that even when no one is in the nether, their command blocks will stay loaded and running. Then they could have something like this running on a clock:
