# Todo
|
||||
- Add a way to SET the metadatas (will be complicated)
|
||||
- Fix the LICENSE
|
||||
- Add a check if set is done in Node/fields/
|
||||
- Add a table handler for meta::set
|
||||
|
||||
# Special thanks
|
||||
- mgl512 (Le_Docteur) for its locked itemframe which gave me the idea of a tool
|
||||
allowing to see/edit metadatas
|
||||
- Ataron who created the stick's texture

# Command tutorial
|
||||
|
||||
- help => Get help
|
||||
- open (x,y,z) => Open the node to manipulate at pos (x,y,z)
|
||||
- show => Show fields/path list at actual position
|
||||
- enter <path> => Enter next stratum through <path>
|
||||
- quit => Quit actual field and go back to previous stratum
|
||||
- set <name> <value> => Set metadata <name> to <value> (create it if it doesn't exist)
|
||||
- itemstack => Manipulate itemstacks in Node/inventory/*/
|
||||
- read <name> => Read itemstack at field name (itemstring and count)
|
||||
- erase <name> => Erase itemstack at field name
|
||||
- write <name> <itemstring> [<count>] => Set itemstack in field <name> with item <itemstring> and count <count>. Default count is one, 0 not handled.
|
||||
- close => Close node
|
||||
|
||||
Node metadatas look like this :
|
||||
|
||||
Stratum : 0 1 2 ...

||||
