Cobblemon Survival Pack: phases 0-2 and Phase 3 zones and hazards
Free NeoForge 1.21.1 modpack on Cobblemon 1.8.4 built with packwiz, plus the Kotlin companion mod (cobblesurvival) and its built-in data pack. - Phase 0: packwiz pack with Modrinth/CurseForge cross-links, build and export tooling, Prism instance sync, test server with smoke checks. - Phase 1: Poke Ball shaped island (WorldGen Editor preset, seed isle-26), Adrian's biome list, no natural ore, structures without ore or vanilla mobs, no Nether portals, world template builder and world report. - Phase 2: permadeath (CobbleHardcoreMon plus the companion mod's gap fixes), Revival Charm, expensive Healing Machine, Lootr refreshing loot, in-game self-tests on Minecraft's GameTest framework. - Phase 3 so far: 14 zones with their own spawn pools and level bands (tools/zone_layout.py, tools/zone_spawns.py, "zone" spawn condition), Cold Sweat heat and cold as gates with boss-drop insulation recipes, spawn survey and hazard self-tests in tools/quick_check.py.

"""What can exist on the island: dimensions, biomes, structures, natural blocks, mobs.
|
||||
|
||||
Everything is derived from data: world/biomes.json and the world preset for
|
||||
biomes and dimensions, structure and structure-set JSON for structures, biome
|
||||
feature lists and NeoForge biome modifiers for natural blocks, biome spawners
|
||||
and structure spawn overrides for mobs. Minecraft and Cobblemon decide a few
|
||||
things in code; those are the small tables below, each saying where it is from.
|
||||
|
||||
Statuses: "available" (on the island), "conditional" (needs something that may
|

not exist, e.g. the End or a stronghold inside the border), "unavailable".
