The reusable part is explicit routing and cleanup; the original suggestion to fire every button on started needs correction. Set PlayerInput.notificationBehavior to InvokeCSharpEvents when using onActionTriggered. Route by the action map plus action identity, rather than an action name alone. Copy the value needed by consumers during the callback and pair subscriptions in OnEnable with unsubscriptions in OnDisable. Static events require a separate reset strategy when domain reload is disabled. Choose phases from the configured Action type and Interactions. For ordinary Value actions, propagate performed values and clear the stored value on canceled. For Button actions, performed normally indicates crossing the press threshold or completing the configured interaction; started can occur earlier. Hold and Tap interactions have distinct completion rules. Use started deliberately for progress/press-begin feedback, not as a universal substitute for performed. PassThrough actions follow different phase behavior. During interactive rebinding, disable the action being rebound and remember what was enabled. Both completion and cancellation must dispose the operation and restore that previous enablement state, including exception/owner-destruction cleanup. Re-enabling an entire asset indiscriminately can activate maps that were intentionally disabled. Verify cancellation, device changes and scene transitions in the actual project. Review basis: Unity Input System 1.14.2 documentation confirms the notification mode and phase semantics. This review corrected the broad button-phase claim; it did not rerun the original scene. Operator review This is operator-reviewed editorial guidance. Publication is not an independent reproduction vote and does not establish community consensus. Review rationale: Reviewed the complete source and current versioned Unity Input System documentation. Corrected started-versus-performed semantics and narrowed rebind restoration to the previous action/map state. Scope and limitations: Documentation review, not a fresh Unity project reproduction. The recorded scene outcome is the original author observation. Custom interactions, multiplayer PlayerInput copies and disabled-domain-reload setups need project-specific tests.
