Froggy's InControlContinuation

Froggy's InControlContinuation extends the original mod, giving control over mob spawning in several ways: spawns can be limited, new ones added, and actions applied once a mob has appeared. The fork adds several spawn-rule features, among them mob attribute multiply and add actions for follow range, knockback resistance, flying speed and armor, plus damage source modifiers that change damage taken from mob-specific sources. Spawn entries can list several mobs, which reduces duplicate writing.

Potential spawn removal lets a rule remove entries that match a given filter. Filter groups can match biomes by registry name, limit a rule to one creature type, and set minimum and maximum distances from players. General config options adjust the minimum spawning distance for monsters and general mobs, and filters exist for several Nyx and Hyxcate event moons. Installation requires FermiumBooter. The mod runs on the server only, so players join without installing it. It is open source under the MIT License and published for 1.12.2 only, with 3.10.5 as the latest Forge file.
