Struct ARWorldMap

The space-mapping state and set of planes and anchors from an AR session. This is a wrapper for ARKit's ARWorldMap. Note: The ARWorldMap must be explicitly disposed to avoid leaking native resources.

Namespace: UnityEngine.XR.ARKit

Syntax

public struct ARWorldMap : IDisposable, IEquatable<ARWorldMap>

Properties

valid

Use this to determine whether this ARWorldMap is valid, or if it has been disposed.

Declaration

public readonly bool valid { get; }

Property Value

Type	Description
Boolean

Methods

Dispose()

Disposes of the world map. This releases the native ARWorldMap resource.

Declaration

public void Dispose()

Implements

IDisposable.Dispose()

Equals(Object)

Tests for equality.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
Object	obj	The object to compare against.

Returns

Type	Description
Boolean	True if obj is of type ARWorldMap and Equals(ARWorldMap) also returns true; otherwise false.

Overrides

ValueType.Equals(Object)

Equals(ARWorldMap)

Tests for equality.

Declaration

public bool Equals(ARWorldMap other)

Parameters

Type	Name	Description
ARWorldMap	other	The other ARWorldMap to compare against.

Returns

Type	Description
Boolean	True if every field in other is equal to this ARWorldMap, otherwise false.

Implements

IEquatable<T>.Equals(T)

GetHashCode()

Generates a hash suitable for use with containers like HashSet and Dictionary.

Declaration

public override int GetHashCode()

Returns

Type	Description
Int32	A hash code generated from this object's fields.

Overrides

ValueType.GetHashCode()

Serialize(Allocator)

Serialize the ARWorldMap to an array of bytes. This array can be saved to disk and loaded at another time to persist the session, or sent over a network to another ARKit-enabled app to share the session. It is an error to call this method after the ARWorldMap has been disposed. The caller owns the returned NativeArray and is responsible for disposing it.

Declaration

public NativeArray<byte> Serialize(Allocator allocator)

Parameters

Type	Name	Description
Unity.Collections.Allocator	allocator	The allocator to use for the returned NativeArray of bytes.

Returns

Type	Description
Unity.Collections.NativeArray<Byte>	An array of bytes representing the serialized ARWorldMap. The caller owns the memory and is responsible for disposing the NativeArray.

Exceptions

Type	Condition
InvalidOperationException	Thrown if the world map is not valid.
InvalidOperationException	Thrown if the world map could not be serialized to a byte array.

TryDeserialize(NativeArray<Byte>, out ARWorldMap)

Create a new ARWorldMap from a NativeArray of bytes produced from Serialize(Allocator). Use this to create an ARWorldMap from a serialized array of bytes, either loaded from disk or sent from another device.

Declaration

public static bool TryDeserialize(NativeArray<byte> serializedWorldMap, out ARWorldMap worldMap)

Parameters

Type	Name	Description
Unity.Collections.NativeArray<Byte>	serializedWorldMap	An array of bytes representing a serialized ARWorldMap, produced by Serialize(Allocator).
ARWorldMap	worldMap	On success, holds the deserialized ARWorldMap.

Returns

Type	Description
Boolean	True if serializedWorldMap was successfully deserialized, otherwise false.

Operators

Equality(ARWorldMap, ARWorldMap)

Tests for equality. Same as Equals(ARWorldMap).

Declaration

public static bool operator ==(ARWorldMap lhs, ARWorldMap rhs)

Parameters

Type	Name	Description
ARWorldMap	lhs	The left-hand side of the comparison.
ARWorldMap	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	True if lhs is equal to rhs, otherwise false.

Inequality(ARWorldMap, ARWorldMap)

Tests for inequality. Same as !Equals(ARWorldMap).

Declaration

public static bool operator !=(ARWorldMap lhs, ARWorldMap rhs)

Parameters

Type	Name	Description
ARWorldMap	lhs	The left-hand side of the comparison.
ARWorldMap	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	True if lhs is not equal to rhs, otherwise false.
