codeblocks

Codeblock

Can be used to convert between the top line name and internal names, eg PLAYER EVENT and event.
It has only that, and the icon. A codeblock goes as such:

{
    name:       string, // The name on the top of the sign // eg `PLAYER EVENT`
    identifier: string, // The name used inside templates. // eg `event`
    item:       Icon
}

For info on icon see this, it contains info on the blocks you place from your inventory.
