Overview

No Mob Spawning on Trees (NMSOT) is a comprehensive mob spawn control utility for Minecraft. While its primary name suggests a simple fix for creepers falling from forest canopies, the mod is actually a deep configuration engine. It allows users to define complex rules for where, when, and how mobs spawn based on block materials, light levels, moon phases, and biome types.

By default, the mod disables hostile mob spawning on all wood logs and mushroom blocks, effectively making forest floors safer and preventing the 'falling creeper' phenomenon. However, through its nmsot.cfg file, it can be transformed into a tool to create hellish deserts, peaceful plains, or dimension-specific spawn logic.
