Classes
UBlueprintAsyncActionBase
Base class for async actions.
BlueprintCallable factory functions for classes which inherit from UBlueprintAsyncActionBase will have a special blueprint node created for it: UK2Node_AsyncAction. You can stop this node spawning and create a more specific one by adding the UCLAS metadata “HasDedicatedAsyncNode”
UCancellableAsyncAction
Use this if you async action can be aborted.
Base class for asynchronous actions that can be spawned from UK2Node_AsyncAction or C++ code. These actions register themselves with the game instance and need to be explicitly canceled or ended normally to go away. The ExposedAsyncProxy metadata specifies the blueprint node will return this object for later canceling.
