Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Array index out of bounds: 1331090944 from an array of size 48

For some reason, this piece of c++ is causing the editor to crash and after digging through the logs, I found this error that I believe is causing the crash. There are 48 actors in the array FoundActors.

 LogWindows: Error: Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:E:\UE4\UE_4.18\Engine\Source\Runtime\Core\Public\Containers/Array.h] [Line: 610] 
 LogWindows: Error: Array index out of bounds: 1331090944 from an array of size 48

The code I'm talking about is this:

 void UCustomBP::GetClosestChosenActor(APawn* AiPawn, UClass* classToFind, AActor* &TargetActor, FVector &TargetVector) {
     float lastDistanceToWall = 10000;
     int WallIndex;
     UWorld* World = AiPawn->GetWorld();
     TArray<AActor*> FoundActors;
     UGameplayStatics::GetAllActorsOfClass(World, classToFind, FoundActors);
     if (FoundActors.Num() >= 2) {
         for (int Actors = 0; Actors < FoundActors.Num(); ++Actors)
             float DistanceToWall = AiPawn->GetDistanceTo(FoundActors[Actors]);
             if (DistanceToWall < lastDistanceToWall) {
                 lastDistanceToWall = DistanceToWall;
                 WallIndex = Actors;
             if (Actors + 1 == FoundActors.Num()) {
                 TargetActor = FoundActors[WallIndex];
                 TargetVector = FoundActors[WallIndex]->GetActorLocation();
     else {
         TargetActor = FoundActors[0];
         TargetVector = FoundActors[0]->GetActorLocation();

Can someone please tell me what I am doing wrong.
