Inherited Members
Namespace: UnityEngine.InputSystem.Controls
Syntax
public class AxisControl : InputControl<float>
Remarks

Can optionally be configured to perform normalization. Stored as either a float, a short, a byte, or a single bit.

Constructors

AxisControl()

Default-initialize the control.

Declaration
public AxisControl()
Remarks

Defaults the format to FormatFloat.

Fields

clamp

Clamping behavior when reading values. None by default.

Declaration
public AxisControl.Clamp clamp
Field Value
Type Description
AxisControl.Clamp

Clamping behavior.
Remarks

When a value is read from the control's state, it is first converted to a floating-point number.

See Also

clampConstant

When clamp is set to ToConstantBeforeNormalize and the value is outside of the range defined by clampMin and clampMax, this value is returned.

Declaration
public float clampConstant
Field Value
Type Description
Single

Constant value to return when value is outside of clamping range.

clampMax

Upper end of the clamping range when clamp is not None.

Declaration
public float clampMax
Field Value
Type Description
Single

Upper bound of clamping range. Inclusive.

clampMin

Lower end of the clamping range when clamp is not None.

Declaration
public float clampMin
Field Value
Type Description
Single

Lower bound of clamping range. Inclusive.

invert

If true, the input value will be inverted, i.e. multiplied by -1. Off by default.

Declaration
public bool invert
Field Value
Type Description
Boolean

Whether to invert the input value.

normalize

If true, normalize the input value to [0..1] or [-1..1] (depending on the value of normalizeZero. Off by default.

Declaration
public bool normalize
Field Value
Type Description
Boolean

Whether to normalize input values or not.
See Also

normalizeMax

If normalize is on, this is the input value that corresponds to 1 of the normalized [0..1] or [-1..1] range.

Declaration
public float normalizeMax
Field Value
Type Description
Single

Input value that should become 1.
Remarks

In other words, with normalize on, input values are mapped from the range of [normalizeMin..normalizeMax] to [0..1] or [-1..1] (depending on normalizeZero).

normalizeMin

If normalize is on, this is the input value that corresponds to 0 of the normalized [0..1] or [-1..1] range.

Declaration
public float normalizeMin
Field Value
Type Description
Single

Input value that should become 0 or -1.
Remarks

In other words, with normalize on, input values are mapped from the range of [normalizeMin..normalizeMax] to [0..1] or [-1..1] (depending on normalizeZero).

normalizeZero

Where to put the zero point of the normalization range. Only relevant if normalize is set to true. Defaults to 0.

Declaration
public float normalizeZero
Field Value
Type Description
Single

Zero point of normalization range.
Remarks

The value of this property determines where the zero point is located in the range established by normalizeMin and normalizeMax.

If normalizeZero is placed at normalizeMin, the normalization returns a value in the [0..1] range mapped from the input value range of normalizeMin and normalizeMax.

If normalizeZero is placed in-between normalizeMin and normalizeMax, normalization returns a value in the [-1..1] mapped from the input value range of normalizeMin and normalizeMax and the zero point between the two established by normalizeZero.

scale

Whether the scale the input value by scaleFactor. Off by default.

Declaration
public bool scale
Field Value
Type Description
Boolean

True if inputs should be scaled by scaleFactor.

scaleFactor

Value to multiple input values with. Only applied if scale is true.

Declaration
public float scaleFactor
Field Value
Type Description
Single

Multiplier for input values.
