Struct InputStateBlock

Information about a memory region storing state.

Namespace: UnityEngine.InputSystem.LowLevel

Syntax

public struct InputStateBlock

Remarks

Input state is kept in raw memory blocks. All state is centrally managed by InputManager; controls cannot keep their own independent state.

Each state block is tagged with a format code indicating the storage format used for the memory block. This can either be one out of a set of primitive formats (such as "INT") or a custom format code indicating a more complex format.

Memory using primitive formats can be converted to and from primitive values directly by this struct.

State memory is bit-addressable, meaning that it can be offset from a byte address in bits (bitOffset) and is sized in bits instead of bytes (sizeInBits). However, in practice, bit-addressing memory reads and writes are only supported on the FormatBit.

Input state memory is restricted to a maximum of 4GB in size. Offsets are recorded in 32 bits.

public uint bitOffset { get; set; }

Property Value

Type	Description
System.UInt32

byteOffset

Remarks

Used for safety checks to make sure that when the system copies state memory, it copies between compatible layouts. If set to a primitive state format, also used to determine the size of the state block.
