|
||||
- 0.9 - Added support for Wine mod's wine barrels
|
||||
- 1.0 - New furances do not work properly with hoppers so old reverted to abm furnaces
|
||||
- 1.1 - Hoppers now work with new node timer Furnaces. Reduced Abm's and tidied code.
|
||||
- 1.2 - Added simple API so that hoppers can work with other containers.

Hopper API
|
||||
----------
|
||||
|
||||
This API is kept simple by adding a single command which allows mods to add
|
||||
containers like chests and furnaces to the hopper check list.
|
||||
|
||||
|
||||
Command Usage
|
||||
-------------
|
||||
|
||||
Make sure any mods using this function has 'hopper' in the depends.txt file.
|
||||
|
||||
hopper:add_container({ {"where_from", "node_name", "inventory_name"} })
|
||||
|
||||
'where_from' is a string telling the api that items are coming from either
|
||||
the 'top', going to the 'bottom' or coming from the 'side'.
|
||||
|
||||
'node_name" is the name of the container itself (e.g. "default:chest")
|
||||
|
||||
'inventory_name' is the name of the container inventory that is affected.
|
||||
|
||||
e.g.
|
||||
|
||||
hopper:add_container({
|
||||
{"top", "default:furnace", "dst"}, -- take cooked items into hopper
|
||||
{"bottom", "default:furnace", "src"}, -- insert items to be cooked from hopper
|
||||
{"side", "default:furnace", "fuel"}, -- replenish furnace fuel from hopper
|
||||
})
|
||||
|
||||
|
||||
We already have support for the wine barrel inside of the Wine mod and protected
|
||||
chests inside of Protector Redo, as well as default chests, furnaces and hoppers
|
||||
themselves.
