Syntax
class UBlueprintEventNodeSpawner : public UBlueprintNodeSpawner
Remarks
Takes care of spawning UK2Node_Event nodes. Acts as the "action" portion of certain FBlueprintActionMenuItems. Will not spawn a new event node if one associated with the specified function already exits (instead, Invoke() will return the existing one). Evolved from FEdGraphSchemaAction_K2AddEvent and FEdGraphSchemaAction_K2ViewNode.
