A Minecraft block list generator
'B'while in-game to open the block list.
'CTRL' + 'B'to re-generate the block list.
'B' button is re-bindable within the Controls menu.
Generating the blocklist may take a little while and may freeze the game temporarily. The list only needs to be generated when you first open it, or when you manually choose to re-generate it (after adding new blocks for example).
The block list is actually just a simple static web-page that can be accessed without the need for Minecraft to be open.
The page can be opened from
minecraft/config/blockley/index.html using a web-browser.
Note that the icon images are stored under
minecraft/config/blockley/images/.. and must be moved along-side the
index.html file if you want to relocate it (it's simpler to just leave it where it is and create a shortcut instead).
