The event is triggered when enabling InputAction by another InputAction with the same key

Thank you for reporting a bug to Unity. After reviewing the behavior, we've confirmed it aligns with the current design and intended use of the feature. We understand this may differ from your expectations or workflow. From testing, I noticed that both Action's are enabled in the example you provided, therefore when you try to enable Action2 it is already enabled causing the action to trigger. When using project wide input assets, all actions are enabled by default. This is opposite to the case when not using the asset, which I know is confusing, but for now this is by design. To solve your issue in your provided project, you can simply disable Action2 in the Awake function like this: private void Awake() { m_playerInput.onActionTriggered += EVENT_OnTriggered; m_playerInput.actions.FindActionMap("TestMap").Enable(); DisableAction(m_reference2); EnableAction(m_reference1); } We will close this case as 'As Designed.' If you have feedback on how the feature could better meet your needs, please let us know - we value your input and consider it in future improvements.

In the repo project you provided you are trying to enable an action that is already enabled. To resolve this you can disable that action in the Awake method like this: private void Awake() { m_playerInput.onActionTriggered += EVENT_OnTriggered; m_playerInput.actions.FindActionMap("TestMap").Enable(); DisableAction(m_reference2); EnableAction(m_reference1); } I hope that helps!
