Checks if a node is protected.

Note: this page has been written for Advtrains 2.0.1 TSS and Minetest 5.1.0. Examples and practices described in this page don't take advantage of improvements introduced in later releases.

advtrains.is_protected(pos, name)

• pos (table): a Minetest vector position.
• name (string): the player name. It does not need to be logged in, but it *needs* to exist in the auth.txt file.

It gives an error if the name parameter is nil:

2019-01-01 15:00:00: Error[Server]: advtrains.is_protected() called without name parameter!

This Lua function checks whether the designated player has the protection_bypass privilege. If not, it checks whether the node is protected by using the minetest.is_protected function, which may be overridden by protection mods.

If the player has the protection_bypass privilege, Advtrains considers all nodes “unprotected” regardless of current protection status.

Consider that you are running a Minetest server and:

• Two players, alice and bob are connected to the server
• alice has the protection_bypass privilege while bob has no privileges
• Node at position (0,1,5) has been protected

advtrains.is_protected({x=0,  y=1,y=5}, "alice") -- returns false: node is protected, but protection bypass is enabled for this user
advtrains.is_protected({x=0,  y=1,y=5}, "bob")   -- returns true: node is protected
advtrains.is_protected({x=-10,y=0,y=0}, "bob")   -- returns false: node is not protected
