Bevy Basics Who Observes the Observer

In this episode of Bevy Basics, we dive deep into one of Bevy's most powerful — and least documented — features: observers. From the motivations behind their design to how to implement them in your own ECS systems, we explore: 🧠 What observers are and how they differ from pull-based systems like event readers and change detection ⚡️ How to create reactive, recursive, and event-driven logic using triggers 🔁 Event propagation and bubbling with Bevy's new traversal system 🛠️ How to spawn, configure, and understand observer internals 🧪 Speculation, internals, and open questions about Bevy's black-box ECS magic If you've struggled to understand how observers work — or want to level up your Bevy app’s responsiveness — this video will get you started and then some. 💬 Know something I missed?
