The module will create a "magical one block" for every new island that is being created
Setting up OneBlock
When using the OneBlock addon, you still to configure SuperiorSkyblock2 as necessary. This means you will need to change your schematics (you don't want regular islands for OneBlock do you?) as well as any other configuration files to fit your OneBlock experience to your liking. The central block of your schematic will be the generating block (your 'one' block) so keep this in mind when creating new schematics.
Players still need to use the /is create <name> [schematic] command to create their OneBlock island - this can be configured in the settings.
