Unity Deprecated InstanceID. Do This Instead!
Unity 6.5 is about to break a ton of editor tools and Asset Store packages. In this video, we break down the complete migration from the old InstanceID / GetInstanceID() system to the new EntityId. We look at real-world examples from actual Unity packages, covering method replacements (GetEntityId, EntityIdToObject), hierarchy callbacks, version-safe wrappers, extension methods, and clever preprocessor tricks used by professional developers. Whether you're getting deprecation warnings in 6.4 or preparing for the hard errors in 6.5, this practical guide shows you exactly how to update your code cleanly and future-proof it for the ECS-for-All future. Don't let your editor tools break — watch this before Unity 6.5 drops!
