First of all, I’ve been browsing the other questions related to the QuickStart guide for a while and I haven’t found an answer to my question.
So I’ve been trying to make the QuickStart guide work from this page:
https://docs.unrealengine.com/latest/INT/Programming/QuickStart/3/index.html
I’ve done all the previous steps exactly the same way (same project name, class names…) and building the “empty” project with no classes worked fine as I was able to open it up in the editor.
But once I come to step 3 where I need to copy the sample code and build it I get errors:
1>------ Build started: Project: QuickStart, Configuration: Development_Editor x64 ------
1> Compiling game modules for hot reload
1> Parsing headers for QuickStartEditor
1> Reflection code generated for QuickStartEditor
1> Performing 2 actions (4 in parallel)
1> FloatingActor.cpp

========== Build: 0 succeeded, 1 failed, 1 up-to-date, 0 skipped ==========
So yes the error is appearing here in the cpp file:
AFloatingActor::AFloatingActor()
It says that the class AActor has no default constructor. I might be a bit rusty in C++ but I don’t see why I’m getting this error. I mean AFloatingActor inherits from AActor and AActor has a default constructor unless I’m blind/crazy. Any help would be really appreciated.
PS: I’m using Unreal Engine 4.6.1
EDIT: Ok so I’ve looked into the source code and I can’t see the default constructor for AActor anywhere inside Actor.cpp/Actor.h. Previously I said that AActor has a default constructor that is because I’ve been looking at the online doc that says it here:
But inside the source code the declaration is missing. Now unless I’m completely wrong (which is possible since I’ve been out of touch with C++ for some time now), since AActor has already a custom constructor: AActor(const FObjectInitializer& ObjectInitializer); this means that if one wants to use the default constructor like AActor(); one has to explicitly declare it. This is really making me crazy… >_>
