Hi! I am trying to get my gamemode do stuff when the game begins & every tick. Something I noticed that the default header file for GameMode does not include this, and just inserting “virtual void BeginPlay() override;” will not work. So… what does?
*Thanks in advance!
What you are doing should work fine. In my custom GameMode I have this:
//.h
UCLASS()
class SPACECOOP_API AGameModeCombat : public AGameMode
{
GENERATED_BODY()
public:
virtual void Tick(float DeltaSeconds) override;
virtual void BeginPlay() override;
}
// .cpp
void AGameModeCombat::BeginPlay()
{
Super::BeginPlay();
// ...
}
void AGameModeCombat::Tick(float DeltaSeconds)
{
Super::Tick(DeltaSeconds);
}
Works fine. If it’s not working for you - post any errors or your code, so we can help figure it out.
oh, well that explains. I did not know not implementing a function in .cpp too would lead to “unresolved external symbol”, I understood it as “there is no beginplay() to override”, and never thought adding the .cpp side of things would fix it.
I guess I learned something much more general and fundamental than I thought I would 
Thank you so much! 
EDIT: I successfully made the gamemode print “Hello World!” on BeginPlay(), and you can’t tell how happy it makes me :P. I finally “did a thing” in C++
