Failed to resolve parent path

Error message

Failed to resolve parent path {path}. Reason: {e:?}

What it means

In fyrox-graph, revert_inheritable_property resolves the given property path on the parent entity to find the inheritable value to revert to. If resolve_path fails (path doesn't exist on the parent, e.g. after script/schema changes), this error is logged and the revert silently does nothing. It usually signals a stale property path saved in an older scene.

Solutions

1. Verify the property path exists on the parent node type (check the current struct/reflect definition)
2. Re-save the scene with the current engine version so paths are regenerated
3. Use the Fyrox editor's property inspector to pick the correct path instead of hand-typing
4. If reverting many properties, resolve the path first and skip missing ones gracefully

fn path_exists_on(node: &dyn Reflect, path: &str) -> bool {
    node.as_reflect().resolve_path(path, &mut |r| r.is_ok());
    // capture via Cell<bool> in real code
    true
}

let ok = Cell::new(false);
parent.resolve_path(path, &mut |r| { ok.set(r.is_ok()); });
if !ok.get() { Log::warn(format!("skip unknown path {path}")); return; }

When it happens

Trigger: Calling revert_inheritable_property with a property path that does not resolve on the parent node — parent's structure changed, typo in path, or property removed from the type since the scene was saved.

Common situations: Scenes saved with an older engine/fyrox version where node properties were renamed or moved, custom script variables removed, editing property paths by hand in the editor UI.
