MiniaczQ 49338245ea Generalize StateTransitionEvent<S> to allow identity transitions (#13579) ... # Objective This PR addresses one of the issues from [discord state discussion](https://discord.com/channels/691052431525675048/1237949214017716356). Same-state transitions can be desirable, so there should exist a hook for them. Fixes https://github.com/bevyengine/bevy/issues/9130. ## Solution - Allow `StateTransitionEvent<S>` to contain identity transitions. - Ignore identity transitions at schedule running level (`OnExit`, `OnTransition`, `OnEnter`). - Propagate identity transitions through `SubStates` and `ComputedStates`. - Add example about registering custom transition schedules. ## Changelog - `StateTransitionEvent<S>` can be emitted with same `exited` and `entered` state. --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com>		2024-06-04 14:23:24 +00:00
