Continents and Isles

A Minecraft NeoForge 1.21.1 world generation mod that creates a single vast supercontinent with coastlines and beaches, surrounded by scattered islands in the outer ocean.

Note: After updating, delete the old config file to let it regenerate. Any config changes require creating a new world to take effect.

Features

- Single supercontinent with configurable radius (default ~4250 blocks), coastlines and beaches.
- Six themed sectors: Snowy Plains, Mountains, Jungle, Savanna, Desert, and Archipelago.
- WiFi-shaped mountain sector with concentric arc ridges rising toward the encircling ring mountain belt.
- Ring mountain belt with randomly placed ore veins (diamond, gold, redstone, iron, copper, coal, lapis).
- Three great lakes: East Lake (island lake), Mountain Lake (deep lake, 50% chance of Tianchi ring effect), and a random sector lake that can appear in any sector except Mountains and Archipelago.
- Archipelago sector with wetland and beach bands; inner-sea islands pushed outward and sector range expanded, inner-sea outward warping removed. Guaranteed Mushroom Island, deep ocean preserved around ocean monuments, and witch huts guaranteed in wetland bands.
- Guaranteed structures: desert temples, woodland mansions, ocean monuments.
- Fully configurable via config file: continent radius, sector biomes and ratios, lake toggles, plus new `biome_rules` for fine-tuned biome placement — blacklist or only-allow across the supercontinent, outer islands, ring mountain belt, each of the six sectors, and inner Archipelago islands independently. A biome can be whitelisted in multiple regions to restrict it to their union.
- Modded biome support: roughly 12% chance to mix in biomes from other mods.

Planned Updates

- Hard cliff and reef transitions along both sides of the Archipelago sector.
- Blended transition zones between neighboring sectors to replace sharp biome borders.
- Desert sector: rivers and lakes removed (random sector lakes exempt), replaced by scattered oasis areas.
- Ring mountain belt and mountain sector redesign—specific details still being considered.
- Refined logic for modded biome placement across the world.

Compatibility

- Lightly tested with several popular biome and structure mods; no conflicts found so far.
- When "When Dungeons Arise" is installed, a structure always generates at the spawn point. I have not fixed this issue.
- Other biome mods have not been exhaustively tested; unknown if any biomes or structures fail to generate.
- Single-biome islands (including underground biomes) should be compatible with most biome generation mods.

Note: This mod was entirely made by AI. The current version largely meets the author's needs; future updates depend on circumstances. If you have ideas or suggestions, feel free to leave them in the comments.

一个 Minecraft NeoForge 1.21.1 世界生成模组，生成单一超大陆与外围群岛。

注意： 更新模组后请删除旧版配置文件以重新生成。修改配置后需重新创建世界方可生效。

功能特性

- 单一超大陆，半径可配置（默认约 4250 格），拥有不太自然的海岸线与沙滩。
- 六大扇区：雪原、山脉、丛林、热带草原、沙漠、群岛。
- WiFi 形山脉扇区，同心弧状山脊与峡谷交错，越靠近环山带越高。
- 环山带环绕整片大陆，随机分布钻石、金、红石、铁、铜、煤、青金石矿脉。
- 三大湖泊：东湖（岛湖）、山湖（深湖，50% 概率出现天池环形效果）、以及可在除山脉与群岛外任意扇区随机出现的群系湖泊。
- 群岛扇区新增湿地带与沙滩带；内海岛屿位置向外偏移，扇区范围扩大，移除内海对外的扭曲效果；必定生成蘑菇岛，海洋神殿周围保留深海区；湿地带固定生成女巫小屋。
- 必生结构：沙漠神殿、林地府邸、海洋神殿。
- 完全可配置：大陆半径、扇区主副群系及比例、湖泊开关等均可调整；新增 `biome_rules` 群系规则，可对超大陆、外海群岛、环山带、六大扇区及群岛内岛分别设置黑名单或白名单，同一群系可写入多个「只允许」列表以限定在多个区域的组合中出现。
- 模组群系支持：安装其他群系模组时约 12% 概率混入。

预计下次更新

- 群岛扇区两侧将加入悬崖与礁石过渡带。
- 各扇区之间计划设计自然过渡区域，告别生硬的群系切换。
- 沙漠扇区将移除河流与湖泊（随机群系湖泊除外），增加散落的绿洲。
- 环山带与山脉扇区将进行重构，具体方案仍在构思中。
- 规划不同模组群系的生成逻辑。

兼容性

- 已简单测试过数个热门群系和结构生成模组，暂未发现冲突。
- 加入「地牢浮现之时」（When Dungeons Arise）后，必定会在出生点生成一个结构。这个问题我目前没有解决。
- 尚未精细测试各类群系模组，暂不了解是否存在群系或结构无法生成的情况。
- 内海群岛与外海岛屿均为单一群系岛屿（含地下群系），理应兼容大部分群系生成模组。
