Changelog:
|
|
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
