you havent made your config file yet. thats why it doesnt save the coordinates as what ive see.

Why are return false and hitter separated?

i have
$this->path = $this->api->plugin->createConfig($this, array());

But there are no contents in the config.

oh

But about spawn-protectino? ....

Oh and there is no API 13.

I did something like this, but used player.interact instead of that.

But that would allow fire damage etc.

but mine will also make it only /op can grief that area

This is due to the vanilla protection.

yeap

Oh, I was trying to mimic williamtdrs ctf, cant hit your own team.
