[DOCS] Incorrect docs for interface casts for Blueprints

[dreamland]

On the page for Interfaces (https://docs.unrealengine.com/en-US/…ces/index.html) under “Determining If a Class Implements Your Interface” it says the following:

For compatability with both C++ and Blueprint classes that implement your interface, use any of the following functions:

bool bIsImplemented = OriginalObject->GetClass()->ImplementsInterface(UReactToTriggerInterface::StaticClass()); // bIsImplemented will be true if OriginalObject implements

UReactToTriggerInterface. bIsImplemented = OriginalObject->Implements<UReactToTriggerInterface>(); // bIsImplemented will be true if OriginalObject implements UReactToTriggerInterfacce.

IReactToTriggerInterface* ReactingObjectA = Cast<IReactToTriggerInterface>(OriginalObject); // ReactingObject will be non-null if OriginalObject implements UReactToTriggerInterface.

That clearly states “any of the following functions” for “Blueprints”, but the last function does not work.

Cast<IReactToTriggerInterface>(OriginalObject) // will always be null if OriginalObject is a blueprint instance

Also typo in UReactToTriggerInterfacce

This still seems to be an issue for me in 5.2.1.
