This mod will teleport players back to where they started digging if they try to dig through protection.

Known Problems

• It cannot handle very long lag.
• Occasionally players who try very hard to break through protection while in the air will jump up and down rapidly. This won't last very long though.

minetest.is_protected

This mod overrides minetest.node_dig and calls a third argument in minetest.is_protected: digger This argument can be safely ignored, so existing mods aren't broken by this.

Usage in other mods

In a protection mod change the definition of minetest.is_protected and call protection_lagporter.check(pos, name) to support the digger option.

A table of players being teleported is available with protection_lagporter.glitching, player names will either be nil if not teleporting or true if they are.

		return true
	end
	return protector.old_is_protected(pos, digger, digging)
end

function minetest.is_protected(pos, name, digging)

end

Node Definitions

In node definitions you should use the digger argument, minetest.is_protected(pos, name, digger), if you test for protection in on_dig. This is only needed if the node is walkable.
