Hello after quite long break ;)
I'd merged placki's version and... I've added
cool new teleport system (as cisoun suggested - they now work like PORTALS :D)
How it works? First, place 2 teleports somewhere. Second, connect them mutually. Third, try them :)
The best effect is when you place 2 'flying' horizontal teleports and jump from large altitude onto one :)
To make it working you must add this line to minetest.conf:
crafted_teleports = 2
There are some weird bugs so we need more testing! Placki, please try upgrading your server :)
