Requires Fabric API
Allows modification of some gameplay aspects within structures (f.e. mining/placing blocks) via datapacks
Mod is required on both server and client.
Datapacks:
All info in readme file.
Additional things:
- blocks get
placed_by_playerproperty, which is true when block was placed by player - status effects disabled by
status_effectrestriction are saved toinactiveStatusEffectswhich are displayed in inventory (their icons are transparent) - structures are being ticked once every 1.5s and only if there is at least one player inside
Known issues:
- structure effects can be removed with milk bucket
- some blocks doesn't have
placed_by_playerproperty due to block property limit - some blocks may change their
placed_by_playerproperty value in inappriopriate way (pistons for example) - structure detection delay can be abused
