Get FProperty type name?

Development Programming & Scripting C++

I’m working on level scripting tool that uses the reflection system heavily. I have the pointer to a UFunction and I want to list out the function parameters and their types (bool, float, object*, etc..).

Is it possible to get the type name for an FProperty or do I need to compare against the different property classes and make up a string myself?

This is what I have so far:

UFunction* Function = TargetObject->FindFunction(...); // function ptr

for (TFieldIterator<FProperty> It(Function); It && It->HasAnyPropertyFlags(CPF_Parm); ++It)
{
	FProperty* LocalProp = *It; // function param ptr
	checkSlow(LocalProp);

	FString PropName = LocalProp->GetFName().ToString(); // param name

	FFieldClass* PropClass = LocalProp->GetClass();
	FString PropType = PropClass->GetFName().ToString(); // param type

	if (PropClass->IsChildOf(FStructProperty::StaticClass()))
	{
		FStructProperty* StructProp = CastField<FStructProperty>(LocalProp);
		UStruct* Struct = StructProp->Struct;
		PropType = Struct->GetFName().ToString(); // if param is a struct, use struct name instead
	}

	UE_LOG(LogTemp, Log, TEXT("(%s) %s"), *PropType, *PropName);
}

Try out GetCPPType :

FString Type, Type2;
Type = Prop->GetCPPType(&Type2);
UE_LOG(LogTemp, Log, TEXT("(%s%s) %s"), *Type, *Type2, *Prop->GetName());

Thanks! Found an implementation in FHeaderViewListItem::GetCPPTypenameForProperty if anyone is interested.
