Version: 2.2 (with optional abm for self-healing) Please configure this mod in config.lua Changelog: 26.02.19 - Removing a travelnet can now be done by clicking on a button (no need to wield a diamond pick anymore) 26.02.19 - Added compatibility with MineClone2 22.09.18 - Move up/move down no longer close the formspec. 22.09.18 - If in creative mode, wield a diamond pick to dig the station. This avoids conflicts with too fast punches. 24.12.17 - Added support for localization through intllib. Added localization for German (de). Door opening/closing can now handle more general doors. 17.07.17 - Added more detailled licence information. TNT and DungeonMasters ought to leave travelnets and elevators untouched now. Added function to register elevator doors. Added elevator doors made out of tin ingots. Provide information about the nearest elevator network when placing a new elevator. This ought to make it easier to find the right spot. Improved formspec. 16.07.17 - Merged several PR from others (Typo, screenshot, documentation, mesecon support, bugfix). Added buttons to move stations up or down in the list, independent on when they where added. Fixed undeclared globals. Changed deprecated functions set_look_yaw/pitch to current functions. 22.07.17 - Fixed bug with locked travelnets beeing removed from the network due to not beeing recognized. 30.08.16 - If the station the traveller just travelled to no longer exists, the player is sent back to the station where he/she came from. 30.08.16 - Attaching a travelnet box to a non-existant network of another player is possible (requested by OldCoder). Still requires the travelnet_attach-priv. 05.10.14 - Added an optional abm so that the travelnet network can heal itshelf in case of loss of the savefile. If you want to use this, set travelnet.enable_abm = true in config.lua and edit the interval in the abm to suit your needs. 19.11.13 - moved doors and travelnet definition into an extra file - moved configuration to config.lua 05.08.13 - fixed possible crash when the node in front of the travelnet is unknown 26.06.13 - added inventory image for elevator (created by VanessaE) 21.06.13 - bugfix: wielding an elevator while digging a door caused the elevator_top to be placed - leftover floating elevator_top nodes can be removed by placing a new travelnet:elevator underneath them and removing that afterwards - homedecor-doors are now opened and closed correctly as well - removed nodes that are not intended for manual use from creative inventory - improved naming of station levels for the elevator 21.06.13 - elevator stations are sorted by height instead of date of creation as is the case with travelnet boxes - elevator stations are named automaticly 20.06.13 - doors can be opened and closed from inside the travelnet box/elevator - the elevator can only move vertically; the network name is defined by its x and z coordinate 13.06.13 - bugfix - elevator added (written by kpoppel) and placed into extra file - elevator doors added - groups changed to avoid accidental dig/drop on dig of node beneath - added new priv travelnet_remove for digging of boxes owned by other players - only the owner of a box or players with the travelnet_remove priv can now dig it - entering your own name as owner_name does no longer abort setup 22.03.13 - added automatic detection if yaw can be set - beam effect is disabled by default 20.03.13 - added inventory image provided by VanessaE - fixed bug that made it impossible to remove stations from the net - if the station a player beamed to no longer exists, the station will be removed automaticly - with the travelnet_attach priv, you can now attach your box to the nets of other players - in newer versions of Minetest, the players yaw is set so that he/she looks out of the receiving box - target list is now centered if there are less than 9 targets --]] travelnet = {}; travelnet.targets = {}; -- Boilerplate to support localized strings if intllib mod is installed. if minetest.get_modpath( "intllib" ) and intllib then travelnet.S = intllib.Getter() else travelnet.S = function(s) return s end end local S = travelnet.S; minetest.register_privilege("travelnet_attach", { description = S("allows to attach travelnet boxes to travelnets of other players"), give_to_singleplayer = false}); minetest.register_privilege("travelnet_remove", { description = S("allows to dig travelnet boxes which belog to nets of other players"), give_to_singleplayer = false}); -- read the configuration dofile(minetest.get_modpath("travelnet").."/config.lua"); -- the normal, default travelnet -- TODO: save and restore ought to be library functions and not implemented in each individual mod! -- called whenever a station is added or removed travelnet.save_data = function() local data = minetest.serialize( travelnet.targets ); local path = minetest.get_worldpath().."/mod_travelnet.data"; local file = io.open( path, "w" ); if( file ) then file:write( data ); file:close(); else print(S("[Mod travelnet] Error: Savefile '%s' could not be written."):format(tostring(path))); end end travelnet.restore_data = function() local path = minetest.get_worldpath().."/mod_travelnet.data"; local file = io.open( path, "r" ); if( file ) then local data = file:read("*all"); travelnet.targets = minetest.deserialize( data ); file:close(); else print(S("[Mod travelnet] Error: Savefile '%s' not found."):format(tostring(path))); end end -- punching the travelnet updates its formspec and shows it to the player; -- however, that would be very annoying when actually trying to dig the thing. -- Thus, check if the player is wielding a tool that can dig nodes of the -- group cracky travelnet.check_if_trying_to_dig = function( puncher, node ) -- if in doubt: show formspec if( not( puncher) or not( puncher:get_wielded_item())) then return false; end -- show menu when in creative mode if( creative and creative.is_enabled_for(puncher:get_player_name()) -- and (not(puncher:get_wielded_item()) -- or puncher:get_wielded_item():get_name()~="default:pick_diamond")) then ) then return false; end local tool_capabilities = puncher:get_wielded_item():get_tool_capabilities(); if( not( tool_capabilities ) or not( tool_capabilities["groupcaps"]) or not( tool_capabilities["groupcaps"]["cracky"])) then return false; end -- tools which can dig cracky items can start digging immediately return true; end -- minetest.chat_send_player is sometimes not so well visible travelnet.show_message = function( pos, player_name, title, message ) if( not( pos ) or not( player_name ) or not( message )) then return; end local formspec = "size[8,3]"..
