if the AnswerN is greater or equal to the .Num() then it will be an out of bounds exception.
if there is still a crash the debug statement should flush to the Log file before the engine actually crashes. though you can for example in Visual studio try attaching the Visual Studio Debugger see if the crash still triggers, and poke around at the local values being worked with.
you might want to add a check on the
if ( GetComponent == Zero )
// to become
if (GetComponent == Zero && AnswerN < RightAnswers.Num())
to enforce that AnswerN should not cause an out of bounds.
the other possibility is that there is no Material in the Materials array on your Zero member (this should be a Null Reference or Null Access Violation instead of an out of bounds though)
if neither of these help then could your provide more details, like text from the Crash report (just the top lines of the call stack will point out most issues)
I’m guessing these are your definitions in the header
UPROPERTY();
TMap<int,FString> RightAnswers;
UPROPERTY();
int AnswerN;
UPROPERTY();
int RAnswers;
Before checking a TMap directly by it’s key, you first need to see if the map contains the key. Otherwise you are accessing the internal key array with a bad index causing an out of bounds error
void APanal::Interact(UPrimitiveComponent* GetComponent, ABaseFirstPersonCharacter* SelfCharacter)
{
if (GetComponent == Zero)
{
if (RightAnswers.Contains(AnswerN)) // <-- this is important!!!
{
if (RightAnswers[AnswerN] == Zero->GetMaterials()[0]->GetName())
{
RAnswers -= -1;
}
}
}
if (GetComponent == One)
{
UE_LOG(LogTemp, Warning, TEXT("BananaI"));
}
if (AnswerN == 3)
{
if (RAnswers == 3)
{
UE_LOG(LogTemp, Warning, TEXT("You win"));
}
else
{
UE_LOG(LogTemp, Warning, TEXT("You lose"));
}
}
}
Nope. TMap will trigger a nullptr check if key not found, it won’t throw any “out of bounds” errors
Either way I believe OP just uses a TArray that is accessed by wrong index
Sorry for waiting and poor description of the problem. When i create BP and interact with it all in normal but when i restart unreal my BP broken(I try recreate) i can t go to the scene and open it i have a crash.
I try to add in APanal::APanal()
RightAnswers.Add("apple");
And do this
if (RightAnswers.Num()>=1 and RightAnswers[AnswerN] == Zero->GetMaterials()[0]->GetName())
what is in the crash report? (the error being thrown at at least the top few lines of the call stack)
there are many reasons the Editor/Engine can crash, and each of them have different solutions.
for things dealing with Content browser try to do those things in blueprints, as they are more suited for it, otherwise you end up with Runtime-Resolved-Hard-References that can silently fail because something got renamed or moved, or spelling error.
With chat GPT i find this. For RAnswers and AnswerN int16 and don t use UPROPERTY(EditAnywhere, BlueprintReadOnly)
Now I have other crash)
In some reason
