    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>
