Adds food to the vacuum oven recipes:
|
||
|
|
* Upgrades food items - vacuum two food items to create a condensed and packaged version that restores 3 times as much health/stamina.
|
||
|
|
* Food items are items that are of the group "food_*" and have an on_use (presumably minetest.item_eat)
|
||
|
|
* To ensure all food items are seen, any mods that add foods must be added as a dependent mod to Terumet - by default only "farming" is
