Disruption

When a block is placed, destroyed, burned by fire or blown up, the server checks the positions around it for blocks that lost their support. Unsupported blocks then fall as entities and deal damage on impact, with the damage growing with the fall distance, similar in spirit to falling anvils. The mod draws its design from the older Enviromine mod and is described as a significantly more performant successor to Block Physics for Fabric.

The search for supports follows a set of vectors across the X-Z plane, with blocks able to reach further depending on their hardness and blast resistance. Pillars and encased positions are also checked, so floating blocks held up only from the side are handled. Game events that fit related tags trigger these disruption checks by default, and the server can cap how many block updates a single event may process, with the default set at 50.

The mod is configurable through its scaling settings for hardness and blast resistance, the damage modifier and its maximum, and the list of game events that start a check. It is server-side only, so players join without installing anything, and it is released under the Mozilla Public License 2.0, making it open source with its source code and issue tracker public. Files exist for Quilt on 1.18.2 only, with version 1.0.0 published on 2022-05-27.
