Fabric Mod

LiminalWheatMod

Create a Fabric 1.21 mod called "Liminal Wheat World". When creating a new world with this mod enabled, the Overworld should generate as: - Infinite completely flat terrain. - Layers: - Bedrock - Dirt - Dirt - Dirt - Farmland - Every farmland block must have fully-grown wheat (minecraft:wheat age=7). - No trees. - No flowers. - No grass. - No tall grass. - No ferns. - No sugar cane. - No pumpkins. - No melons. - No caves visible from the surface. - No lakes. - No rivers. - No structures. - No villages. - No ruined portals. - No mineshafts. - No strongholds. - No animals.

Read the full description

- No hostile mobs. - Use a single Plains biome everywhere. - The world should be compatible with Minecraft Java 1.21.x. Generate a complete Gradle Fabric project that builds successfully with Fabric Loom. Do not use placeholders or pseudocode. Implement the world generation in Java.
