Demonstrated on an iPhone connected wirelessly to the Unity editor, the feature uses a code watcher that detects saves and pushes updates instantly. Examples shown include tweaking run speed, jump height, and adding a double jump mechanic in real time, as well as tuning pickup frequency in an endless runner. Multiple agents can also make simultaneous script changes during live play testing. The feature is planned for release within the year. ## Full article daily.dev links to this article rather than hosting it.
