| description | EventBus guidance for behavior-to-behavior messaging in Studio 3D. Use when behaviors need decoupled communication, topic design, or event lifecycle cleanup. |
Use this skill when behaviors need publish/subscribe communication.
This is primarily a behavior-authoring skill, not a scene-command skill.
Always:
Use EventBus when systems should be decoupled. Do not use it as a replacement for plain local state.

stemstudio-behaviorsstemstudio-game-engineAsset search (local and external), asset metadata lookup, model import, and 3D model generation for Studio 3D. Use for finding, inspecting, downloading, and placing 3D models in the scene.
Scene lighting, light object properties, fog, background, tone mapping, and post-processing for Studio 3D. Use for mood, atmosphere, shadows, and visual environment setup.
Add sound effects and audio to 3D scenes in Studio 3D game engine. Use when the user asks to add sounds, music, audio feedback, or sound effects to objects or events. Covers the genericSound behavior for event-triggered audio, audio resource management, and common patterns like ambient sound, collision SFX, UI click sounds, and background music. Examples include "add a sound when the coin is collected", "play background music", "add footstep sounds to the character", or "make the button click sound".
Behavior discovery, creation, update, attach/detach, and configuration in Studio 3D. Use for built-in behavior reuse first, then custom behavior authoring only when needed.
Camera type, perspective, and configuration for Studio 3D. Use for camera type selection, FOV, clipping planes, and genre-appropriate camera setup.
Master routing skill for StemStudio ACP work. Use for broad or ambiguous requests such as "make a game", "build a scene", "improve this", or any task that needs skill selection, scene inspection, staged execution, and clean scene hierarchy.
