Aibridge Prefab Patch

AIBridge Prefab Patch

Use prefab patch when one Prefab edit needs multiple operations in one load/save cycle. For single-field or small batched edits, prefer inspector set_property or inspector set_properties. For scene objects, prefer gameobject, transform, and inspector. For unsupported operations, load unity-yaml-editing

参数选择

• Prefer --ops <file> for multi-step edits, nested JSON, arrays, references, or anything run from PowerShell
• Use --ops-json <json> only for one or two very small operations
• Put temporary operation files under .aibridge/patch_ops/
• Always run --dryRun true before writing the prefab

标准流程

1. Find the target prefab with asset find/search --format paths
2. Inspect structure with prefab get_hierarchy --prefabPath "<prefab>"
3. Create .aibridge/patch_ops/<task>.json
4. Run dry-run:

$CLI prefab patch --prefabPath "Assets/Prefabs/Player.prefab" --ops ".aibridge/patch_ops/player_hp_patch.json" --dryRun true

5. If dry-run succeeds, run the same command without --dryRun true
6. Re-check hierarchy/properties, then run compile unity and get_logs --logType Error

操作示例

[
  { "op": "ensure_child", "path": "Player/HP" },
  { "op": "set_property", "target": { "path": "Player/HP", "componentName": "Animator" }, "propertyName": "m_Enabled", "value": true }
]

Supported ops: ensure_child, ensure_component, set_property, set_properties, set_array, append_array, clear_array. See references/prefab-reference.md for full op schemas

不支持时的处理

If an operation is not covered by patch ops, load unity-yaml-editing and follow its Decision Order

引用写法

Use these object reference values inside value or array items:

{ "$gameObject": "Player/HP" }
{ "$component": { "path": "Player/HP", "typeName": "Animator" } }
{ "$asset": "Assets/Materials/HPMat.mat" }
{ "$guid": "asset-guid" }
null

注意事项

• Do not edit Prefab YAML directly; for unsupported operations use unity-yaml-editing
• Duplicate child names or component types are ambiguous; use exact hierarchy paths and componentIndex
