This mod allows for entities to be spawned when players break blocks. Any block can be configured to spawn a single entity out of a provided array, with a specified chance and toggles for terrain adjustment and immediate player targeting.
Example configurationThe attempts to spawn entities are in the order they are defined in the configuration file, meaning an entity that is second in order will only have a chance to be spawned if the one before it fails to.
