Exchange Shop [bitchange]
|
|
|
|
This code is based on the idea of Dan Duncombe's exchange shop

https://web.archive.org/web/20160403113102/https://forum.minetest.net/viewtopic.php?id=7002
|
|
You do not need the entire bitchange mod to use this code.
|
|
Make sure you've got all textures to use it in a separate mod.
