Struct EntityGuid

This component is attached to converted Entities and is guaranteed to be unique within a World. It can be used to map back to the authoring GameObject from which it was converted. Note that an EntityGuid does not have enough information to be persistent across sessions.

Implements

IComponentData

IQueryTypeParameter

Namespace: Unity.Entities

Assembly: solution.dll

Syntax

[Serializable]
public struct EntityGuid : IComponentData, IQueryTypeParameter

Constructors

Name	Description
EntityGuid(int, int, uint, uint)	Initializes a new instance of the EntityGuid.

Fields

Name	Description
Null	Static value that represents an invalid EntityGuid.
a	This field, when combined with b, is for working with EntityGuid as opaque bits (the packing may change again in the future, as there are still unused bits remaining).
b	Use same as a field.

Properties

Name	Description
OriginatingId	Session-unique ID for originating object (typically the authoring GameObject's InstanceID).
OriginatingSubId	Secondary session-unique ID for the originating object. This is typically the authoring Component's InstanceID.
Serial	A unique number used to differentiate Entities associated with the same originating object and namespace.

Methods

Name	Description
CompareTo(EntityGuid)	Compares an EntityGuid against a given one to find their sort order.
Equals(object)	Checks if two objects are EntityGuid instances and if they are equal.
Equals(EntityGuid)	Checks if two EntityGuid instances are equal.
GetHashCode()	Computes a hashcode to support hash-based collections.
ToString()	Converts this EntityGuid to a standard C# string representation.

Operators

Name	Description
operator ==(in EntityGuid, in EntityGuid)	Checks if two EntityGuid instances are equal.
operator !=(in EntityGuid, in EntityGuid)	Checks if two EntityGuid instances aren't equal.
