Added in display item rotation
Updated the Readme. Added in the ability to rotate the displayed item with a screwdriver. Made the Screwdriver mod required, due to rotating the item being fundamental behavoir. Finalized a few bug fixes... still have to remove the all of the forced debug code, and move the item frames and glow frames over to the new api, and do a final test.

This mod is originally by Zeg9, but heavily modified for MineClone 2.
|
||||
This mod has been rewritten and revamped by Michieal / Faerraven. Based on the code originally done by Zeg9, and then
|
||||
heavily modified by the Mineclone 2 dev team.
|
||||
|
||||
This mod now supports all the base item frame functions, like rotating the displayed item, which it didn't do before it
|
||||
was rewritten. Additionally, Glow Frames have been added in, and item frames now has an API to allow new item frames to
|
||||
be created in other modules.
|
||||
Now requires the Screwdriver to have full functionality.
|
||||
|
||||
The code is licenced under the standard MineClone 2 license for usage, with the requirement that this readme is
|
||||
included in the code / module.
