Properties

aliases

Declaration
public ReadOnlyArray<InternedString> aliases { get; }
Property Value
Type Description
ReadOnlyArray<InternedString>

arraySize

Declaration
public int arraySize { get; }
Property Value
Type Description
Int32

bit

Declaration
public uint bit { get; }
Property Value
Type Description
UInt32

defaultState

Optional default value for the state memory associated with the control.

Declaration
public PrimitiveValue defaultState { get; }

Type Description
PrimitiveValue

Optional display name of the control.

Declaration
public string displayName { get; }
Property Value
Type Description
String

dontReset

Get or set whether the control should be excluded when performing a device reset.

Declaration
public bool dontReset { get; }
Property Value
Type Description
Boolean

If true, the control will not get reset in a device reset. Off by default.
Remarks

Some controls like, for example, mouse positions do not generally make sense to reset when a device is reset. By setting this flag on, the control's state will be excluded in resets.

Note that a full reset can still be forced through ResetDevice(InputDevice, Boolean) in which case controls that have this flag set will also get reset.

format

Declaration
public FourCC format { get; }
Property Value
Type Description
FourCC

isArray

Declaration
public readonly bool isArray { get; }
Property Value
Type Description
Boolean

isFirstDefinedInThisLayout

Whether the control is introduced by the layout.

Declaration
public bool isFirstDefinedInThisLayout { get; }
Property Value
Type Description
Boolean

If true, the control is first introduced by this layout.
Remarks

The value of this property is automatically determined by the input system.

isModifyingExistingControl

If true, the item will not add a control but rather a modify a control inside the hierarchy added by layout. This allows, for example, to modify just the X axis control of the left stick directly from within a gamepad layout instead of having to have a custom stick layout for the left stick than in turn would have to make use of a custom axis layout for the X axis. Instead, you can just have a control layout with the name "leftStick/x".

Declaration
public bool isModifyingExistingControl { get; }
Property Value
Type Description
Boolean

isNoisy

Get or set whether to mark the control as noisy.

Declaration
public bool isNoisy { get; }
Property Value
Type Description
Boolean

Whether to mark the control as noisy.
Remarks

Noisy controls may generate varying input even without "proper" user interaction. For example, a sensor may generate slightly different input values over time even if in fact the very thing (such as the device orientation) that is being measured is not changing.

See Also

isSynthetic

Get or set whether to mark the control as "synthetic".

Declaration
public bool isSynthetic { get; }
Property Value
Type Description
Boolean

Whether to mark the control as synthetic.
Remarks

Synthetic controls are artificial controls that provide input but do not correspond to actual controls on the hardware. An example is anyKey which is an artificial button that triggers if any key on the keyboard is pressed.

layout

Name of the layout to use for the control.

Declaration
public InternedString layout { get; }
Property Value
Type Description
InternedString

Name of layout to use.
Remarks

Must be the name of a control layout, not device layout.

An example would be "Stick".

maxValue

Declaration
public PrimitiveValue maxValue { get; }
Property Value
Type Description
PrimitiveValue

minValue

Declaration
public PrimitiveValue minValue { get; }
Property Value
Type Description
PrimitiveValue

name

Name of the control. Cannot be empty or null.

Declaration
public InternedString name { get; }
Property Value
Type Description
InternedString

Name of the control.
Remarks

This may also be a path of the form "parentName/childName...". This can be used to reach inside another layout and modify properties of a control inside of it. An example for this is adding a "leftStick" control using the Stick layout and then adding two control layouts that refer to "leftStick/x" and "leftStick/y" respectively to modify the state format used by the stick.

This field is required.
