Declaration
protected IEnumerable<Type> BuildAvailableVariableTypes(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 blackboard for variable creation, or null to offer none.
Description
Builds the set of variable types offered in the blackboard for variable creation.
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. Variables of any type can still be created
programmatically via Graph.CreateVariable 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> BuildAvailableVariableTypes(IReadOnlyCollection<Type> baseSupportedTypes)
{
// Start from the auto-discovered types, then add or remove as needed.
foreach (var t in baseSupportedTypes)
if (t != typeof(Untyped))
yield return t;
yield return typeof(Vector3);
}
