Select a notification behavior

You can use the Behavior property in the Inspector to determine how a PlayerInput component notifies game code when something related to the player has occurred.

The following options are available:

Behavior value (UI)	Description	Matching enum value
Send Messages	Uses GameObject.SendMessage on the GameObject that the PlayerInput component belongs to.	SendMessages
Broadcast Messages	Uses GameObject.BroadcastMessage on the GameObject that the PlayerInput component belongs to. This broadcasts the message down the GameObject hierarchy.	BroadcastMessages
Invoke Unity Events	Uses a separate UnityEvent for each individual type of message. When this is selected, the events available on the PlayerInput are accessible from the Events foldout. The argument received by events triggered for Actions is the same as the one received by started, performed, and canceled callbacks.	InvokeUnityEvents
Invoke CSharp Events	Similar to Invoke Unity Events, except that the events are plain C# events available on the PlayerInput API. You cannot configure these from the Inspector. Instead, you have to register callbacks for the events in your scripts. The following events are available: onActionTriggered (collective event for all actions on the player) onDeviceLost onDeviceRegained	InvokeCSharpEvents

In addition to per-action notifications, PlayerInput sends the following general notifications:

Notification	Description
DeviceLostMessage	The player has lost one of the Devices assigned to it. This can happen, for example, if a wireless device runs out of battery.
DeviceRegainedMessage	Notification that triggers when the player recovers from Device loss and is good to go again.
