Struct InputControlScheme

A named set of zero or more device requirements along an associated binding group.

Inherited Members
System.Object.Equals(System.Object, System.Object)
System.Object.ReferenceEquals(System.Object, System.Object)
System.Object.GetType()
Namespace: UnityEngine.Experimental.Input
Syntax
public struct InputControlScheme : IEquatable<InputControlScheme>
Remarks

Control schemes provide an additional layer on top of binding groups. While binding groups allow differentiating sets of bindings (e.g. a "Keyboard&Mouse" group versus a "Gamepad" group), control schemes impose a set of devices requirements that must be met in order for a specific set of bindings to be usable.

Constructors

InputControlScheme(String, String, IEnumerable<InputControlScheme.DeviceRequirement>)

Declaration
public InputControlScheme(string name, string basedOn = null, IEnumerable<InputControlScheme.DeviceRequirement> devices = null)
Parameters
Type Name Description
System.String name
System.String basedOn
IEnumerable<InputControlScheme.DeviceRequirement> devices

Properties

baseScheme

Name of control scheme that this scheme is based on.

Declaration
public string baseScheme { get; }
Property Value
Type Description
System.String
Remarks

When the control scheme is enabled, all bindings from the base control scheme will also be enabled. At the same time, bindings act as overrides on bindings coming through from the base scheme.

bindingGroup

Binding group that is associated with the control scheme.

Declaration
public string bindingGroup { get; set; }
Property Value
Type Description
System.String
Remarks

All bindings in this group as well as in groups inherited from base control schemes are considered to be part of the control scheme.

deviceRequirements

Devices used by the control scheme.

Declaration
public ReadOnlyArray<InputControlScheme.DeviceRequirement> deviceRequirements { get; }
Property Value
Type Description
ReadOnlyArray<InputControlScheme.DeviceRequirement>
Remarks

No two entries will be allowed to match the same control or device at runtime in order for the requirements of the control scheme to be considered satisfied. If, for example, one entry requires a "<Gamepad>" and another entry requires a "<Gamepad>", then at runtime two gamepads will be required even though a single one will match both requirements individually. However, if, for example, one entry requires "<Gamepad>/leftStick" and another requires "<Gamepad>, the same device can match both requirements as each one resolves to a different control.

name

Name of the control scheme.

Declaration
public string name { get; }
Property Value
Type Description
System.String
Remarks

May be empty or null except if the control scheme is part of an InputActionAsset.
