Look up bindings

You can retrieve the bindings of an action using its InputAction.bindings property which returns a read-only array of InputBinding structs.

    // Get bindings of "fire" action.
    var fireBindings = playerInput.actions["fire"].bindings;

Also, all the bindings for all actions in an InputActionMap are made available through the InputActionMap.bindings property. The bindings are associated with actions through an action ID or action name stored in the InputBinding.action property.

    // Get all bindings in "gameplay" action map.
    var gameplayBindings = playerInput.actions.FindActionMap("gameplay").bindings;

You can also look up the indices of specific bindings in InputAction.bindings using the InputActionRebindingExtensions.GetBindingIndex method.

    // Find the binding in the "Keyboard" control scheme.
    playerInput.actions["fire"].GetBindingIndex(group: "Keyboard");

    // Find the first binding to the space key in the "gameplay" action map.
    playerInput.FindActionMap("gameplay").GetBindingIndex(
        new InputBinding { path = "<Keyboard>/space" });

Finally, you can look up the binding that corresponds to a specific control through GetBindingIndexForControl. This way, you can, for example, map a control found in the controls array of an InputAction back to an InputBinding.

    // Find the binding that binds LMB to "fire". If there is no such binding,
    // bindingIndex will be -1.
    var fireAction = playerInput.actions["fire"];
    var bindingIndex = fireAction.GetBindingIndexForControl(Mouse.current.leftButton);
    if (binding == -1)
        Debug.Log("Fire is not bound to LMB of the current mouse.");
