Fabric Mod Snippets

A comprehensive snippet pack for Minecraft Fabric mod development in VS Code.

This extension provides ready‑to‑use snippets for:

• Registries
• Items
• Blocks
• Block Items
• Entities
• Entity Renderers
• Data Generation (models, loot tables, recipes, tags)
• Fabric entrypoints
• Gradle properties
• Loom build scripts
• Fabric mod JSON

Designed for Fabric 1.21.11, Yarn mappings, and modern Loom.

Usage

Type any snippet prefix (e.g., reg.item, block.basic, datagen.model) and VS Code will suggest completions.

Tip: If you upgrade Minecraft/Fabric, update these versions consistently along with your build.gradle and Loom configuration.

Patterns and Best Practices

• Centralize registrations (items, blocks, entities) in domain classes and call them from a single ModRegistries.register() entry.
• Keep datagen providers small and focused; prefer explicit models and loot tables to reduce runtime JSON mistakes.
• Always register default attributes for living entities to prevent crashes.
• Use tags (BlockTags, ItemTags) whenever possible; they simplify compatibility.
• Prefer Identifier.of(MOD_ID, "name") over string concatenation; it’s safer and clearer.
• Add optional comments to toggle common behaviors (e.g., .requiresTool(), Models.HANDHELD, luminance).

Compatibility Notes

• Snippets target the modern Fabric API patterns used around MC 1.21.11.
• If you’re on a different version, adapt:
  • Fabric Loader/API, Yarn mappings, Loom, and Gradle versions in the gradle snippets.
  • Some class/method names can shift across mappings or versions.

Troubleshooting

• Snippet not triggering: Ensure the file language mode matches (Java or properties/JSON) and that this extension is installed; for local development ensure files remain under snippets/java and snippets/json.
• Red types/methods: Verify your Fabric/Yarn dependencies line up with the targeted versions in your project.
• Data gen providers: Run datagen with your Loom tasks and ensure the entrypoint is declared in fabric.mod.json when needed.

If you spot a missing pattern or want an additional variant (e.g., block states for stairs/slabs, recipe advancements, complex model builders), create a new snippet in this folder following the same placeholder and comment conventions.
