How to set "Run Construction Script on Drag" in C++?

[Zhi_Kang_Shao]

I want to set the value of that “Run Construction Script on Drag” boolean in C++ rather than blueprint, because it is important for performance reasons and I don’t want to have project members memorize that every time they make a blueprint based off my C++ class.

But that was exactly what I was looking for, thanks! Here is what I do now:

ATileDecorator::ATileDecorator()
{
	UBlueprint* Blueprint = Cast<UBlueprint>(GetClass()->ClassGeneratedBy);
	if (Blueprint)
		Blueprint->bRunConstructionScriptOnDrag = false;
}
