Use `nil` for the `options` parameter to unregister the function associated with the given identifier.
|
|
|
|
Use `nil` for the `get_formspec` field to denote that the function does not have its own screen.
|
|
|
|
Use `nil` for the `privs` field to denote that no special privileges are required to use the function.
|
|
|
|
If the identifier is already registered to another function, it will be replaced by the new one.
|
|
|
|
The `on_select` function must not call `worldedit.show_page`
