You Shall Not Spawn! is a powerful utility mod designed to give players and modpack creators granular control over entity spawning within Minecraft. It directly addresses the common issue of unwanted mobs or entities appearing in a world, which can disrupt gameplay balance, create performance problems, or simply be an annoyance. By providing a flexible configuration system, this mod allows for the complete prevention of specific entities from ever spawning, ensuring a more tailored and predictable game environment. This is particularly valuable for those looking to curate a specific experience or remove entities that might conflict with other mods or intended gameplay mechanics. The mod operates by utilizing JSON configuration files, offering two primary methods for controlling entity spawns. The first is a straightforward blacklist, where players can add the IDs of entities they wish to completely prevent from spawning. The second method allows for more nuanced control, enabling players to manage the spawn rate of entities on a global scale or on a per-dimension basis. This means you can not only remove entities entirely but also reduce their frequency to a desired level, offering a sophisticated approach to managing the game's ecosystem. Furthermore, the mod supports regular expressions, which is a significant advantage for managing multiple entities from a single mod or those with similar naming patterns, streamlining the configuration process considerably. This mod is designed for broad compatibility across popular mod loaders and recent Minecraft versions. It supports Forge, Fabric, and Quilt, and is available for Minecraft versions 1.20.3, 1.20.4, 1.20.5, 1.20.6, 1.21, 1.21.1, 1.21.2, and 1.21.3. The functionality of You Shall Not Spawn! is primarily server-side, meaning it is required on the server to enforce spawn restrictions. While it is not strictly necessary on the client, it is recommended to include it on client installations as well, especially for players who might engage in single-player worlds where the mod's configuration can still be beneficial for managing spawns. Installing You Shall Not Spawn! is straightforward and depends on the mod loader you are using. For Forge and NeoForged mod loaders, the mod file should be placed in the `mods` folder of your Minecraft installation. For Fabric and Quilt, the process is the same, with the `.jar` file going into the `mods` folder. Before launching the game, it is crucial to ensure that the mod's configuration files, specifically `disabled entities.json5` and `per dimension entities.json5`, are correctly placed within the `config/ysns/` directory. These files are essential for the mod to function as intended, and they come with helpful comments and examples to guide you through the setup process.
