Msw General

If you're building anything in MapleStory Worlds, read this first. It enforces a core principle: MSW isn't about prototypes, it's about polished games, so every entity needs proper sprites, animations, and sounds applied via the search skill. The real value is the workflow discipline it hammers in: never start models from scratch (use the validated template catalog), always use builders instead of hand-editing files, and if an entity appears twice or more in a map, author a model first and place instances rather than copying inline components. The preflight rules are strict (read entity.md before touching entities, read builder-protocol.md before any file writes) but they exist because the three builders are interlocked and skipping documentation breaks the component sync contracts.

MSW General — Foundation Skill

The foundation skill for MSW (MapleStory Worlds) creation, integrating shared tools, domain knowledge, platform rules, and file authoring. Every other MSW skill depends on it.

Core Principle: Visual Polish

MSW is a game creation platform. The goal is not a prototype where logic merely runs — it is a polished game players can enjoy.

So whatever entity you create — monster, NPC, tower, item, background object — search for and apply appropriate resources (sprites, animations, sounds) that match its role and personality. Do not leave the default sprite in place or leave SpriteRUID empty.

Resource application principle when creating an entity:

After creating the entity, use the msw-search skill to find sprites/animations that fit it
Apply the RUID of the found resource to SpriteRendererComponent so the entity is visually represented
If there is combat, also set hit/explosion effects; if there is interaction, set sound effects
