Version: 2.2 (with optional abm for self-healing)
Please configure this mod in config.lua
Changelog:
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
