After tutorial no 188 i just press the play button just to make sure if every thing compiled right but when i press the button UE crashes plz help thanks in advance
You are most likely dereferencing a null pointer. What code have you added for that lecture?
auto Barrel location = Barrel->GetComponentLocation().ToString();
That would imply Barrel
is a null pointer. Did you make sure to set it in blueprint using SetBarrelReference?
Where should i set it in c++ or in ue
void UTankAimingComponent::SetBarrelReference(UStaticMeshComponent* BarrelToSet)
{
this->Barrel = BarrelToSet;
}
i’ve already set in c++
That’s the code that will set it. It’s not going to set it if you don’t call it and that is done in blueprint.
In which file should i set it
The tank blueprint.
i can’t find where
See around 7:18 in the lecture.
Thanks that solves my problem i actually some how missed that part
