BlockBlock is a mod that allows for restricting of things. It's meant to allow modpack creators to progressively unlock things for the player, but it will also work for server staff to prevent players from doing certain actions.
You can lock:
- Breaking of blocks
- Placement of blocks
- Interacting with blocks
- Interacting with entities
- Entity drops
- Crafting recipes
- Usage of items
It's possible for a vanilla client to join a server using this mod. However, it is recommended to install the mod on the client too. If you don't, you will miss out on client-side features like tooltips, but it will also cause more visual 'bugs'. For example, if placement is locked, it will pop in and out of existence really fast, which does not happen if the client has the mod installed.
