SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Game scenes in Summer Engine (Godot-based) often grow ad hoc, producing deep fragile node paths, duplicated inline clusters, and scripts that break whenever the hierarchy is reorganized. This Skill provides a structured method for designing scene hierarchies around the operations the game actually performs. ## Core Features & Use Cases - Access-pattern-driven structure: Group nodes operated on together under wrapper parents, keep type-queried nodes as flat siblings, and keep unique nodes inline. - Asset vs live hierarchy separation: Extract repeated clusters into reusable .tscn sub-scenes and instantiate them instead of duplicating inline setups. - Path-agnostic logic: Replace hardcoded deep node paths with groups, signals, and exported NodePath references so scripts survive reorganization. - Use Case: When building a level with enemies, props, and lighting, structure it with Enemies, Props, and Level wrapper nodes so operations like "remove all enemies" become a single node removal, and repeated crates become instances of one crate.tscn. ## Quick Start Ask the agent to restructure the current level scene so enemies, props, and level geometry each sit under their own wrapper node with reusable setups extracted into sub-scenes.

FAQPage Schema
How do I structure a scene hierarchy in Summer Engine?▼

Structure scenes by access pattern: group nodes operated on together under one wrapper parent, keep nodes queried by type as flat siblings, and keep unique nodes like cameras inline. Read the scene tree with summer_get_scene_tree before making any changes.

When should I use a sub-scene instead of inline nodes in Godot?▼

Extract a setup into its own .tscn sub-scene whenever the same cluster appears two or more times, then instantiate it with summer_instantiate_scene. One-off nodes like a level-specific light or main camera stay inline under the root.

Why do my scripts break when I reorganize the scene tree?▼

Scripts break because they hardcode deep node paths like ./World/Enemies/Grunt_01/Weapon, which change on any reorganization. Use groups, signals, or exported NodePath references instead so logic stays independent of hierarchy shape.

How do I remove all nodes of one type at once in Summer Engine?▼

Place all nodes of that type under a single wrapper parent, then call summer_remove_node on the wrapper to remove the entire subtree in one operation. This is why wrapper nodes should match real operation boundaries.

Can I edit .tscn files directly while the engine is running?▼

No, direct .tscn edits while the engine runs get overwritten when the editor saves. Always mutate scenes through the MCP tools such as summer_add_node, summer_instantiate_scene, and summer_remove_node, passing the exact scenePath.

When should I not use this scene hierarchy approach?▼

Do not use it for shader or material work, asset import mechanics, or gameplay tuning, since it covers only hierarchy shape. Also avoid over-grouping: wrapping every node in its own container adds depth without enabling any real subtree operation.
