Methods

FindAction(string, bool)

Find an InputAction in the collection by its name or by its id (in string form).

Declaration
InputAction FindAction(string actionNameOrId, bool throwIfNotFound = false)
Parameters
Type Name Description
string actionNameOrId

Name of the action as either a "map/action" combination (e.g. "gameplay/fire") or a simple name. In the former case, the name is split at the '/' slash and the first part is used to find a map with that name and the second part is used to find an action with that name inside the map. In the latter case, all maps are searched in order and the first action that has the given name in any of the maps is returned. Note that name comparisons are case-insensitive.

 Alternatively, the given string can be a GUID as given by <xref href="UnityEngine.InputSystem.InputAction.id" data-throw-if-not-resolved="false"></xref>.
bool throwIfNotFound

If true, instead of returning null when the action cannot be found, throw ArgumentException.
Returns
Type Description
InputAction

The action with the corresponding name or null if no matching action could be found.
Exceptions
Type Condition
ArgumentNullException

actionNameOrId is null.
ArgumentException

Thrown if throwIfNotFound is true and the action could not be found. -Or- If actionNameOrId contains a slash but is missing either the action or the map name.

FindBinding(InputBinding, out InputAction)

Find the index of the first binding that matches the given mask.

Declaration
int FindBinding(InputBinding mask, out InputAction action)
Parameters
Type Name Description
InputBinding mask

A binding. See Matches(InputBinding) for details.
InputAction action

Receives the action on which the binding was found. If none was found, will be set to null.
Returns
Type Description
int

Index into bindings of action of the binding that matches mask. If no binding matches, will return -1.
Remarks

For details about matching bindings by a mask, see Matches(InputBinding).

var index = playerInput.actions.FindBinding(
    new InputBinding { path = "<Gamepad>/buttonSouth" },
    out var action);

if (index != -1)
Debug.Log($"The A button is bound to {action}");
