The structure for a crossworld stone
Here you can see the finished product of custom cost with base costs
The basic structure of a default memory stone
Setting up the Memory Stone, added a sign onto it and entering first line as the name of the Memory Stone
Setting up a sign with extra costs. Extra memorization cost on the left and teleportation cost on the right. These will have the base costs (in the structuretypes.yml) added to them.
Using Spout & SpoutCraft, right click with your compass to show the location window where you can simply select to teleport
If all is well, the sign will have a green 'Memory Stone' written with the name below it.
