# Objective A common pitfall since 0.8 is the requirement on `ComputedVisibility` being present on all ancestors of an entity that itself has `ComputedVisibility`, without which, the entity becomes invisible. I myself hit the issue and got very confused, and saw a few people hit it as well, so it makes sense to provide a hint of what to do when such a situation is encountered. - Fixes #5849 - Closes #5616 - Closes #2277 - Closes #5081 ## Solution We now check that all entities with both a `Parent` and a `ComputedVisibility` component have parents that themselves have a `ComputedVisibility` component. Note that the warning is only printed once. We also add a similar warning to `GlobalTransform`. This only emits a warning. Because sometimes it could be an intended behavior. Alternatives: - Do nothing and keep repeating to newcomers how to avoid recurring pitfalls - Make the transform and visibility propagation tolerant to missing components (#5616) - Probably archetype invariants, though the current draft would not allow detecting that kind of errors --- ## Changelog - Add a warning when encountering dubious component hierarchy structure Co-authored-by: Nicola Papale <nicopap@users.noreply.github.com>
