Syntax
public abstract class InputControl<TValue> : InputControl where TValue : struct
Type Parameters
Name Description
TValue

Type of value captured by the control. Note that this does not mean that the control has to store data in the given value format. A control that captures float values, for example, may be stored in state as byte values instead.

public override int valueSizeInBytes { get; }

Methods

CompareValue(Void*, Void*)

Declaration
public override bool CompareValue(void *firstStatePtr, void *secondStatePtr)
Parameters
Type Name Description
Void* firstStatePtr
Void* secondStatePtr
Returns
Type Description
Boolean
Overrides

ProcessValue(TValue)

Declaration
public TValue ProcessValue(TValue value)
Parameters
Type Name Description
TValue value
Returns
Type Description
TValue

ReadDefaultValue()

Get the control's default value.

Declaration
public TValue ReadDefaultValue()
Returns
Type Description
TValue

The control's default value.
Remarks

This is not necessarily equivalent to default(TValue). A control's default value is determined by reading its value from the default state (defaultStatePtr) which in turn is determined from settings in the control's registered layout (defaultState).

ReadUnprocessedValue()

Declaration
public TValue ReadUnprocessedValue()
Returns
Type Description
TValue

ReadUnprocessedValueFromState(Void*)

Declaration
public abstract TValue ReadUnprocessedValueFromState(void *statePtr)
Parameters
Type Name Description
Void* statePtr
Returns
Type Description
TValue

ReadValue()

Get the control's current value as read from currentStatePtr

Declaration
public TValue ReadValue()
Returns
Type Description
TValue

The control's current value.
Remarks

This can only be called on devices that have been added to the system (added).

ReadValueFromBufferAsObject(Void*, Int32)

Declaration
public override object ReadValueFromBufferAsObject(void *buffer, int bufferSize)
Parameters
Type Name Description
Void* buffer
Int32 bufferSize
Returns
Type Description
Object
Overrides

ReadValueFromPreviousFrame()

Get the control's value from the previous frame (previousFrameStatePtr).

Declaration
public TValue ReadValueFromPreviousFrame()
Returns
Type Description
TValue

The control's value in the previous frame.

ReadValueFromState(Void*)

Declaration
public TValue ReadValueFromState(void *statePtr)
Parameters
Type Name Description
Void* statePtr
Returns
Type Description
TValue

ReadValueFromStateAsObject(Void*)

Read the control's final, processed value from the given state and return the value as an object.

Declaration
public override object ReadValueFromStateAsObject(void *statePtr)
Parameters
Type Name Description
Void* statePtr
Returns
Type Description
Object

The control's value as stored in statePtr.
Overrides
Remarks

This method allocates GC memory and should not be used during normal gameplay operation.

See Also

ReadValueFromStateIntoBuffer(Void*, Void*, Int32)

Read the control's final, processed value from the given state and store it in the given buffer.

Declaration
public override void ReadValueFromStateIntoBuffer(void *statePtr, void *bufferPtr, int bufferSize)
Parameters
Type Name Description
Void* statePtr

State to read the value for the control from.
Void* bufferPtr

Buffer to store the value in.
Int32 bufferSize

Size of bufferPtr in bytes. Must be at least valueSizeInBytes. If it is smaller, will be thrown.
Overrides

WriteValueFromBufferIntoState(Void*, Int32, Void*)

Declaration
public override void WriteValueFromBufferIntoState(void *bufferPtr, int bufferSize, void *statePtr)
Parameters
Type Name Description
Void* bufferPtr
Int32 bufferSize
Void* statePtr
Overrides

WriteValueFromObjectIntoState(Object, Void*)

Read a value object and store it as state in the given memory.

Declaration
public override void WriteValueFromObjectIntoState(object value, void *statePtr)
Parameters
Type Name Description
Object value

Value for the control.
Void* statePtr

State containing the control's stateBlock. Will receive the state state as converted from the given value.
Overrides
Remarks

Writing values will NOT apply processors to the given value. This can mean that when reading a value from a control after it has been written to its state, the resulting value differs from what was written.

WriteValueIntoState(TValue, Void*)

Declaration
public virtual void WriteValueIntoState(TValue value, void *statePtr)
Parameters
Type Name Description
TValue value
Void* statePtr
