Serilum's Spawn Bundle

by Serilum

Serilum's Spawn Bundle combines several of Serilum's mob spawn mods into a single installable file, so one install brings in each included spawn change.

What it does

The bundle packs Serilum's spawn-type mods together and uses Jar in Jar, a loader feature that nests the included mods inside the bundle jar. The nested mods stay fully separate from one another, keep their own config files, and still appear individually in the in-game mod list. Each included mod can be switched off through the bundle's config, and a restart is needed for config changes to take effect.

The bundle is aimed at players who want the spawn content without installing each mod by hand, and at modpack makers who prefer one bundled file over a set of modular mods. Because the nested mods are part of the bundle, installing a standalone copy of one of them alongside it is not needed and can cause the mod to load twice. The bundle runs on the server only, so players join without installing anything.

Key features

  1. Bogged spawns

    Bogged mobs can spawn naturally in place of skeletons in most locations.

  2. Breeze spawns

    Breezes can spawn naturally in areas where blazes would normally appear.

  3. Cave spider spawns

    Cave spiders spawn underground in place of regular spiders.

  4. Giant spawns

    Giants can spawn naturally and use custom AI based on zombie behavior.

  5. Husk and horse spawns

    Husks, skeleton horses and zombie horses can spawn naturally, each with its own option in the config.

  6. Mooshroom and zombie villager options

    Mooshroom tweaks and extra zombie villager spawns can be toggled separately in the config.

  7. Per-mob config toggles

    Every spawn type has its own default-enabled option, so any of them can be disabled without removing the bundle.

  8. Other Serilum bundles

    Serilum also publishes the Client, Customization, Extra, QoL and RPG bundles, each grouping its own related mods.

What the author says

The Spawn Bundle is a special type of mod, that combines multiple of Serilum's spawn-type mods into one. While I find it very difficult to group my mods together, I have attempted this to make them easier to install. It uses a system called JiJ (Jar in Jar). This basically means that the included mods remain…
