Declaration

protected IEnumerable<Type> BuildAvailableConstantTypes(IReadOnlyCollection<Type> baseSupportedTypes);

Parameters

Parameter Description
baseSupportedTypes Types auto-discovered from the graph's node port definitions, used as the base set to build upon.

Returns

IEnumerable<Type> The types to offer in the item library for constant nodes, or null to offer none.

Description

Builds the set of types offered in the graph item library for constant nodes.

Override this method to filter or extend the default set. The default implementation returns baseSupportedTypes unchanged. This controls what the UI offers, not what can be created. Constant nodes of any type can still be created programmatically via Graph.CreateConstantNode regardless of this set. Use baseSupportedTypes as the base set; do not call Graph.SupportedTypes from this method, as that would create a circular dependency and throw an InvalidOperationException.

 protected override IEnumerable<Type> BuildAvailableConstantTypes(IReadOnlyCollection<Type> baseSupportedTypes)
 {
     // Start from the auto-discovered types, then add or remove as needed.
     foreach (var t in baseSupportedTypes)
         yield return t;

yield return typeof(Vector3); }
