Method GetComponentOrderVersion

GetComponentOrderVersion<T>()

Gets the version number of the specified component type.

Declaration

[GenerateTestsForBurstCompatibility(GenericTypeArguments = new Type[] { typeof(BurstCompatibleComponentData) })]
public int GetComponentOrderVersion<T>()

Returns

Type	Description
int	The current version number.

Type Parameters

Name	Description
T	The component type.

Remarks

This version number is incremented each time there is a structural change involving the specified type of component. Such changes include creating or destroying entities that have this component and adding or removing the component type from an entity. Shared components are not covered by this version; see GetSharedComponentOrderVersion<T>(T).

 Version numbers can overflow. To compare if one version is more recent than another, directly checking if
 VersionB is greater than VersionA is not sufficient. Instead, use the helper function:

 <pre><code class="lang-csharp">bool VersionBisNewer = ChangeVersionUtility.DidChange(VersionB, VersionA);</code></pre>
