Help me on a Anti-Grief Plugin

My first design is that all the blocks that the OP placed down is not breakable and no other blocks can be put on that unless it it 100 blocks above. so that it will make easier to make a road with out being destroyed or blocked by bear boys... any ideas?

I think You can just protect the roads or other things with your area-protector plugin.

my road design is complicated, if i use the area-protector, it will take way too much time to kept changing places and type commands...

So, I can't help you anymore, I can't code right now, maybe I'll have a look tomorrow

thank you man! i wanted to try myself, but i just learned PHP so i am not really good at it i am now just downloading others plugins and learning.. hopefully i could be better

I'm a beginner too, but I'm already working on a SkyWars plugin, too.
Oh, I forgot that the plugin UBAB (un breakable blocks) could help you with your protections, you should have a look!

thx, i will down load and see'
