Block Spawn

This mod adds the ability for entities to appear when players break blocks. You can configure any block so that when it is destroyed, one entity from a specified list appears with a certain probability. Settings include adjusting the spawn chance, the ability to modify terrain around the entity, and immediate aggression towards the player.

Configuration Example

Attempts to spawn entities occur in the order they are listed in the configuration file. This means that an entity listed second will only have a chance to spawn if the previous entity failed to spawn.
