--- Privileges to control TRAIN DRIVING/COUPLING
-minetest.register_privilege("train_operator", {
- description = "Without this privilege, a player can't do anything about trains, neither place or remove them nor drive or couple them (but he can build tracks if he has track_builder)",
- give_to_singleplayer= true,
-});
-
-minetest.register_privilege("train_admin", {
- description = "Player may drive, place or remove any trains from/to anywhere, regardless of owner, whitelist or protection",
- give_to_singleplayer= true,
-});
-
--- Privileges to control TRACK BUILDING
-minetest.register_privilege("track_builder", {
- description = "Player can place and/or dig rails not protected from him. If he also has protection_bypass, he can place/dig any rails",
- give_to_singleplayer= true,
-});
-
--- Privileges to control OPERATING TURNOUTS/SIGNALS
-minetest.register_privilege("railway_operator", {
- description = "Player can operate turnouts and signals not protected from him. If he also has protection_bypass, he can operate any turnouts/signals",
- give_to_singleplayer= true,
-});
-
--- there is a configuration option "allow_build_only_owner". If this is active, a player having track_builder can only build rails and operate signals/turnouts in an area explicitly belonging to him
--- (checked using a dummy player called "*dummy*" (which is not an allowed player name))

---[[
-Protection/privilege concept:
-Tracks:
- Protected 1 node all around a rail and 4 nodes upward (maybe make this dynamically determined by the rail...)
- if track_builder privilege:
- if not protected from* player:
- if allow_build_only_owner:
- if unprotected:
- deny
- else:
- allow
- deny
-Wagons in general:
- Players can only place/destroy wagons if they have train_operator
-Wagon driving controls:
- The former seat_access tables are unnecessary, instead there is a whitelist for the driving stands
- on player trying to access a driver stand:
- if is owner or is on whitelist:
- allow
- else:
- deny
-Wagon coupling:
- Derived from the privileges for driving stands. The whitelist is shared (and also settable on non-driverstand wagons)
- for each of the two bordering wagons:
- if is owner or is on whitelist:
- allow
-
-*"protected from" means the player is not allowed to do things, while "protected by" means that the player is (one of) the owner(s) of this area
