    [LIVESTREAM] Training Livestream - Getting Started with C++ in UE4 - April 18 - Live at Epic HQ


    WHAT
    Richard Hinckley is joining us for this livestream to help ease new programmers into using UE4's personal flavor of C++. Over the past couple of years that UE4 has been available to the public, Epic has released a lot of C++ content and tutorials that are specifically built for people familiar with coding to begin with, but now we're getting back to basics! What is up with Garbage Collection? How do I make and expose a function to Blueprints? How do Blueprints fit into all of this anyway? These questions and much more will be answered! Also make sure to throw in your beginner questions below so we can answer them live. Be sure to also check out our documentation and wiki articles on C++!

    WHEN
    Tuesday, April 18th @ 2:00PM ET [Countdown]

    WHERE
    Twitch
    Facebook
    Youtube

    WHO
    Richard Hinckley - Sr Learning Resource Engineer
    Alexander Paschall - Community Manager - @UnrealAlexander

    Feel free to ask any questions on the topic in the thread below, and remember, while we try to give attention to all inquiries, it's not always possible to answer everyone's questions as they come up. This is especially true for off-topic requests, as it's rather likely that we don't have the appropriate person around to answer. Thanks for understanding!

                      My Questions for the stream are:

                      Can you go over referencing a class in another class?

                      What are some simple use cases for creating and using an Empty C++ Parent Class in your game?

                      How do you implement input in C++ to call functions?

                        Nice to see another Unreal C++ tutorial!

                        My main question is:
                        What I always found a little confusing and very difficult to find good information on is memory management. For example, I know that objects that inherit from UObject are managed by the Unreal memory manager, but what about C++ objects that don't inherit from it? When do you free those, and when they are part of (encapsulated) by a UObject do you have to free them yourself or not and once again when/where, or is it simply enough to use things like an std::unique_ptr<> to handle this automatically.
                        Of course any additional tips/tricks or tools regarding Unreal memory management would also be very much appreciated!

                        In any case I'm looking forward to the stream!

                          The title looks promising, but the description breaks the hype. I would love to see more C++ and Unreal Framework specific stuff, instead of focusing on exposing functions to Blueprints or the connection with Blueprints in general. I think all the keywords are already explained very well in the documentation and used in Tank game tutorial series. My dream for a full C++ project tutorial will probably never come true. I will still post my hopes even though I can already see they won't get answered :3.

                          Actor Lifecycle: https://docs.unrealengine.com/latest...ctorLifecycle/
                          I think you win the heart of the community if you find an example class that could override all functions when spawning and deferred spawning.

                          Pointer Protection: I see a lot of pointer checks on GetWorld(), GEngine, heck in my project I couldn't even use GetViewportSize from the controller without using a Delay, because something in the background was not already loaded into the engine (and the UnrealMatch3 tutorial is also using this little 'hack/ trick'). I know it's literally impossible to explain how all the engine pieces bring me into my level, especially since PIE and actual game also differ + if the game should implement multiplayer things get even worse. However, a really rough explanation about the most common things that are executed before any BeginPlay() fires would clear some minds.
                          (*edited: I also see some confusion about smart pointers, so that one seems to be another talk you could add Pointer Protection)
                          (Something more specific about Pointer Protection in my project. I'm using ConstructorHelpers::FObjectFinder in my project a lot. I see people are using checks or even Succeed (which just gives a bool back) after this, but when does this even fail. It never failed on my project, but do I assume correct that if it fails, my game doesn't crash, but instead just won't load the asset and the worst case is (if used for a character mesh for example), my character mesh is not showing?)

                          I'm like 90% sure how other actors, components work if I look up their .h and .cpp files (talking about basics like Timers, Delegates etc.), but it's the lack of knowledge about what happens behind the curtains that makes me working with Unreal super unsure and uncomfortable if I'm actually doing stuff right. I would love to work with the engine and not around it :3.

                            Agree with [MENTION=37491]Ninjin[/MENTION], what we need is a coverage about framework "behind the scene".

                              This is off the top of my head, and I'm sure there have been posts about this but I aeem to have missed them:

                              There have been times when FORCEINLINE functions could work with BlueprintCallable / BlueprintPure, and other times where I got errors attempting it. What's the catch there?
