This plugin will be configurable to set up whatever block you want to create a safe zone. Safezone Blocks is a bit like another request called Pathways but is more versatile. You could make a road out of gravel that makes you run faster, while also creating a zone around it where mobs don't spawn. You could also apply this to your house, make your house using that specific block to make sure mobs never spawn there. There will be no need for a command or permission. It would bring an MMO aspect to the server you are making. I would like this plugin soon, but not ASAP
Mirkwood-elf Might do this, I just need some extra details like what block zones would you like and how would I differ them from normal block patches?
