Using Unreal Editor 4.25, in the “Programming Quick Start” guide, **section 4 **“Compile and Test Your C++ Code”, step 3, the cube doesn’t appear in the perspective viewport when I drag it there, nor does the Details panel contain a Transform section for the new FloatingActor (and there is no red dot next to its name in the outliner, unlike the step 4 screenshot), unless I click the Compile button at the top of the Unreal Editor window – just compiling the code in Visual Studio is not enough, the last sentence of step 1 is not optional.
Sorry for wasting your time with such a trivial misstatement but I just spent far too long finding out why I couldn’t follow along.
