Hi guys,
do anyone know, how can I set a variable of a class outside this class?
I have worked through the tutorial “First Person Shooter C++ Tutorial” And now I want to try experimenting…
So I have the class:
class FPSPROJECT_API AFPSHUD : public AHUD
with a public bool.
How can I change this public bool outside?
I am very confused 8(
Can somebody help me ?
Obviously you will need find pointer to object that you want to communicate, study API reference:
Theres also offline version of it in /Engine/Documentation/CHM which i think it easier to work with. Lot of classes got pointers to various objects, so check AHUD:
For example if your bool is in pawn (let say AFPSPawn) possesed by player controller you can do something like this from AHUD:
((AFPSPawn*)PlayerOwner->GetPawn())->bSomeBool=true;
since you didn’t tell where you got your bool i can’t directly help you how to get set that bool in your case
If it’s not hud but some random custom class you’ve created then you just use c++ basics. There are no special requirements by UE for general c++. As soon as you use object of that class type you can always get access to its public variables.
For hud case: there are multiple ways to get it. You have HUD assigned to your Player Controller. You should just get a pointer to proper PC object and get its HUD like this (as example):
AFPSHUD* MyHUD = Cast<AFPSHUD>(()->GetFirstPlayerController()->GetHUD());
MyHUD->MyBooleanVariable = true;
or using Kismet functions. Or getting player controllers’ list iterator. You choose the most convenient way.
Thank you very much!!
