Block Spawn
by n643064
Block Spawn lets a block placed in the world spawn mobs when a player breaks it, with the spawn set by the server's configuration file.
What it does
Each configured block can spawn one entity from a list when a player breaks it. The list is read from a configuration file, and every entry carries its own percentage chance. Entities are tried in the order the file defines, so a second entry is only reached when the first one fails its roll. A namespaced identifier names the block that triggers the spawn.
Two options control what happens around the spawn. One decides whether the terrain around the spawned entity is destroyed, and another keeps the block directly under it in place. A further option sets whether the spawned entity targets the player aggressively. Because these choices live in the configuration file, server owners can tune the behavior without changing any code.
Block Spawn is a server-side only mod for Forge and NeoForge, built for 1.20.1. Only the server needs it, and players join without installing anything. The code is open source under the GNU General Public License v3.0 or later.
Key features
Break-triggered spawning
Breaking a configured block spawns an entity from its list, turning mining into a source of encounters.
Chance per entity
Each entity in a block's list has a percentage chance, so rare and common spawns can share the same block.
Ordered fallback
Entries are attempted in the order written in the configuration, and a later entry is used only when an earlier roll fails.
Terrain adjustment
Options control whether the ground around a new entity is cleared and whether the block beneath it is kept.
Aggression setting
A toggle decides whether a spawned entity targets the player immediately or stays passive.

How it compares
Spawning control is a server-side only Forge mod for 1.20.1 – 1.20.4 under the MIT License, and it is not open source. Structure Spawn Area Fix runs server-side only on Forge and NeoForge for 1.20.1, under All rights reserved and not open source. Light Level 7 Spawning is a server-side only Fabric mod for 1.20.1, released under the MIT License and open source. Block Spawn covers a different trigger, the breaking of a block, so these mods address other spawn rules.
