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

#2

You are most likely dereferencing a null pointer. What code have you added for that lecture?

#3

auto Barrel location = Barrel->GetComponentLocation().ToString();

#4

That would imply Barrel is a null pointer. Did you make sure to set it in blueprint using SetBarrelReference?

#5

Where should i set it in c++ or in ue

#6

void UTankAimingComponent::SetBarrelReference(UStaticMeshComponent* BarrelToSet)
{
this->Barrel = BarrelToSet;
}

i’ve already set in c++

#7

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.

#8

In which file should i set it

#9

The tank blueprint.

#10

i can’t find where

#11

See around 7:18 in the lecture.

#12
