Struct InputControlList<TControl>

Keep a list of InputControl without allocating managed memory.

Namespace: UnityEngine.Experimental.Input
Syntax
public struct InputControlList<TControl> : IList<TControl>, IReadOnlyList<TControl>, IDisposable where TControl : InputControl
Type Parameters
Name Description
TControl
Remarks

Requires the control setup in the system to not change while the list is being used. If devices are removed from the system, the list will no be valid. Also, only works with controls of devices that have been added to the system (meaning that it cannot be used with devices created by before they have been AddDevice<TDevice>(String)).

Allocates unmanaged memory. Must be disposed or will leak memory. By default allocates persistent memory. Can direct it to use another allocator with InputControlList<TControl>.

Constructors

InputControlList(TControl[])

Declaration
public InputControlList(params TControl[] values)
Parameters
Type Name Description
TControl[] values

InputControlList(Allocator, Int32)

Construct a list that allocates unmanaged memory from the given allocator.

Declaration
public InputControlList(Allocator allocator, int initialCapacity = 0)
Parameters
Type Name Description
Allocator allocator
System.Int32 initialCapacity
Examples
// Create a control list that allocates from the temporary memory allocator.
using (var list = new InputControlList(Allocator.Temp))
{
    // Add all gamepads to the list.
    InputSystem.FindControls("<Gamepad>", list);
}

InputControlList(IEnumerable<TControl>, Allocator)

Declaration
public InputControlList(IEnumerable<TControl> values, Allocator allocator = null)
Parameters
Type Name Description
IEnumerable<TControl> values
Allocator allocator

Properties

Capacity

Number of controls that can be added before more (unmanaged) memory has to be allocated.

Declaration
public int Capacity { get; set; }
Property Value
Type Description
System.Int32

Count

Number of controls in the list.

Declaration
public int Count { get; }
Property Value
Type Description
System.Int32

IsReadOnly

Declaration
public bool IsReadOnly { get; }
Property Value
Type Description
System.Boolean

Item[Int32]

Return the control at the given index.

Declaration
public TControl this[int index] { get; set; }
Parameters
Type Name Description
System.Int32 index

Index of control.
Property Value
Type Description
TControl
Remarks

Internally, the list only stores indices. Resolution to InputControl happens dynamically by looking them up globally.
