Documentation

README

Excerpt

Assets / Modify

Three modification surfaces

Use whichever fits the task:

content — full SerializedMember override (legacy, backwards compatible).
pathPatches — list of {path, value} pairs routed through Reflector.TryModifyAt.
jsonPatch — JSON Merge Patch routed through Reflector.TryPatch.

When more than one is supplied they run in this order: jsonPatch → pathPatches → content. At least one is required.

Path syntax

fieldName, nested/field, arrayField/[i], dictField/[key]. Leading #/ is stripped.
