Methods

From(InputDevice, out InputEventPtr, Allocator)

Read the current state of device and create a state event from it.

Declaration
public static NativeArray<byte> From(InputDevice device, out InputEventPtr eventPtr, Allocator allocator = null)
Parameters
Type Name Description
InputDevice device

Device to grab the state from. Must be a device that has been added to the system.
InputEventPtr eventPtr

Receives a pointer to the newly created state event.
Allocator allocator

Which native allocator to allocate memory for the event from. By default, the buffer is allocated as temporary memory (. Note that this means the buffer will not be valid past the current frame. Use if the buffer for the state event is meant to persist for longer.
Returns
Type Description
NativeArray<System.Byte>

Buffer of unmanaged memory allocated for the event.
Exceptions

System.ArgumentException

device has not been added to the system.
System.ArgumentNullException

device is null.
