Hard Spawners

Spawners are made harder to clear in this Fabric mod: a broken spawner can still release mobs one last time. The chance of that final spawn defaults to 50%, and the value is configurable, as is the option to switch the whole mod off. The mod was made mainly for play with dungeon mods, where players often rush through rooms and break spawners before the fight is over.

The change is most noticeable in co-op, where one player fights the mobs while another runs the spawner breaking. Because the mod only touches spawners, it adds no items, blocks or screens. It runs on the server alone, so players join without installing it, and it requires YetAnotherConfigLib (YACL) for its settings. Files cover 1.21.6, 1.21.7 and 1.21.8, with 1.0.0 for 1.21.8 as the latest, and the mod is released under All rights reserved, so it is not open source.
