Class InputProcessor

A processor that conditions/transforms input values.

Inheritance
object
InputProcessor
InputProcessor<TValue>
Namespace: UnityEngine.InputSystem
Assembly: Unity.InputSystem.dll
Syntax
public abstract class InputProcessor
Remarks

To define a custom processor, it is usable best to derive from InputProcessor<TValue> instead of from this class. Doing so will avoid having to deal with things such as the raw memory buffers of Process(void*, int, InputControl).

Note, however, that if you do want to define a processor that can process more than one type of value, you can derive directly from this class.

Properties

cachingPolicy

Caching policy of the processor. Override this property to provide a different value.

Declaration
public virtual InputProcessor.CachingPolicy cachingPolicy { get; }
Property Value
Type Description
InputProcessor.CachingPolicy

Methods

Process(void*, int, InputControl)

Process an input value stored in the given memory buffer.

Declaration
public abstract void Process(void* buffer, int bufferSize, InputControl control)
Parameters
Type Name Description
void* buffer

Memory buffer containing the input value. Must be at least large enough to hold one full value as indicated by bufferSize.
int bufferSize

Size (in bytes) of the value inside buffer.
InputControl control

Optional control that the value originated from. Must have the same value type that the processor has.
Remarks

This method allows processing values of arbitrary size without allocating memory on the GC heap.

See Also

ProcessAsObject(object, InputControl)

Process an input value, given as an object, and return the processed value as an object.

Declaration
public abstract object ProcessAsObject(object value, InputControl control)
Parameters
Type Name Description
object value

A value matching the processor's value type.
InputControl control

Optional control that the value originated from. Must have the same value type that the processor has.
Returns
Type Description
object

A processed value based on value.
Remarks

This method allocates GC heap memory. To process values without allocating GC memory, it is necessary to either know the value type of a processor at compile time and call Process(TValue, InputControl) directly or to use Process(void*, int, InputControl) instead and process values in raw memory buffers.
