Summary
Packages/com.coplaydev.unity-mcp/Editor/Tools/Physics/PhysicsSettingsOps.cs reads and writes the deprecated Physics2D.autoSyncTransforms property in two places, producing CS0618 warnings on Unity 6.x.
Versions
- MCP for Unity: 9.6.8
- Unity: 6000.3.10f1 (Unity 6.3 LTS)
Compiler output
Packages/com.coplaydev.unity-mcp/Editor/Tools/Physics/PhysicsSettingsOps.cs(62,46): warning CS0618: 'Physics2D.autoSyncTransforms' is obsolete: 'Physics2D.autoSyncTransforms has been deprecated please use Physics2D.SyncTransforms instead to manually sync physics transforms when required.'
Packages/com.coplaydev.unity-mcp/Editor/Tools/Physics/PhysicsSettingsOps.cs(284,25): warning CS0618: 'Physics2D.autoSyncTransforms' is obsolete: 'Physics2D.autoSyncTransforms has been deprecated please use Physics2D.SyncTransforms instead to manually sync physics transforms when required.'
Locations
- Line 62 — get path:
autoSyncTransforms = Physics2D.autoSyncTransforms inside the 2D snapshot returned by the get action.
- Line 284 — set path:
Physics2D.autoSyncTransforms = prop.Value.Value<bool>(); inside the "autosynctransforms" case of the 2D set switch.
Suggested fix
Unity removed the auto-sync property in favor of an explicit Physics2D.SyncTransforms() call. A few reasonable shapes:
- Drop
autoSyncTransforms from the 2D snapshot and from the set switch entirely. Add an action like manage_physics { dimension: "2d", action: "syncTransforms" } that simply calls Physics2D.SyncTransforms().
- Keep the public field name for back-compat in the response but report
autoSyncTransforms = false as a fixed value, and turn the setter into a no-op that logs a deprecation note. Add the explicit-sync action alongside.
- Wrap both lines in
#pragma warning disable CS0618 / restore if the intent is to keep mirroring the legacy property until the Unity API is fully removed.
Same situation likely applies to Physics.autoSyncTransforms (3D) — worth checking when patching.
Impact
Warnings only, not errors. The 2D manage_physics path still works on Unity 6.x because Unity hasn't removed the property yet, only deprecated it. Filing now so the fix lands before Unity removes the API outright.
