Hi,
I hoped to get some explanation in this video about the difference between:
HitActor->GetNa…
and for example
GetOwner()->FindCom…
Why is there sometimes the brackets before the arrow and sometimes not, and more importantly how can I learn to find out what I would need?
One is a function the other is a variable.
HitActor is a AActor pointer variable we created.
AActor* HitActor = Hit.GetActor();
Hit has a function called GetActor which returns an AActor* and we use that to initialise our variable HitActor.
Ah ok, so business as usual basically.
If I want to point to a method I use brackets, if I want to point to variable, I just use the arrow without brackets
Not to. We aren’t pointing to a variable per se or pointing to a function.
GetOwner() is a function that returns an AActor pointer so then we would use the arrow operator to access the returrned AActor's methods, like GetName() which is a AActor function which returns an FString(not a pointer) so we can call it’s methods like ToUpper() using the dot operator since the FString isn’t a pointer, i.e. GetOwner()->GetName().ToUpper()
Okay I think this makes sense.
I am having a little trouble using the right words/phrases, but I feel like I understand the differences.
Thank you for the explanations!
