What msw-general does

This skill sets the shared groundwork for MapleStory Worlds: how to find resources, how to author .model and .map files, which platform rules to follow. Other MSW skills reference it, so it comes first.

Inside is a catalog of validated .model templates grouped by category: monsters, NPCs, player, terrain, map objects, particles, sound, tile maps, UI. Starting a new .model from an empty file is discouraged — pick the closest template, swap the three identifiers (EntryKey, Id, Name) through ModelBuilder, then adjust components. Save into a typed subfolder of RootDesk/MyDesk/Models/, for example Models/Monsters/{Name}.model, then refresh.

There is a separate rule for repeated objects: if the same entity shows up in a map twice or more, author a .model and place instances by modelId instead of copy-pasting @components. One edit in the model updates every instance, and the .map stays readable. Dynamic spawning through SpawnByModelId needs a model regardless of count. Before touching entities the skill requires reading references/entity.md; before editing .map, .model or .ui it requires the builder protocol.

What it helps with

  • build a monster or NPC .model from a ready template
  • place five identical trees via modelId instead of copy-paste
  • match a sprite and animation to an entity's role
  • wire hit effects and interaction sounds
  • keep model and map instances from drifting apart

Example prompts for the agent

  • read msw-general and build a .model for a chasing monster
  • use msw-general to place 10 trees via modelId in this map
  • check with msw-general that every entity has SpriteRUID set

Questions about msw-general

How do I install msw-general in Claude?

Run npx skills add MSW-Git/msw-ai-coding-plugins-official --skill msw-general -a claude-code. The skill lands at ~/.claude/skills/msw-general/SKILL.md.

What does msw-general do?

It provides the shared layer for MapleStory Worlds work: a catalog of .model templates, rules for placing entities, and the reading order for reference docs. Other MSW skills depend on it.

When do I need a model instead of inline components?

A one-off entity in a single map can use inline components. At two or more instances the skill requires a .model with modelId instances.
