Hi, I’ve run into an issue where it always logs Something went wrong.it cannot do line trace and also that’s why I can’t call the AimAt method because it always returns false.
bool AMyPlayerController_Class::getHitLocation(FVector worldDirection, FVector &hitlocation) const {
FHitResult hitResult;
auto cameraLocation = PlayerCameraManager->GetCameraLocation();
auto endLocation = cameraLocation + (worldDirection*LineTraceRange);
if (GetWorld()->LineTraceSingleByChannel(hitResult,cameraLocation,endLocation,ECollisionChannel::ECC_Visibility)){
hitlocation = hitResult.Location;
return true;
}
DrawDebugLine(GetWorld(),
cameraLocation, endLocation,
FColor(255, 0, 0), 0.f, 0.f, 0.F, 3.F);
hitlocation = FVector(0);
UE_LOG(LogTemp, Warning, TEXT("Something went wrong"))
return false;
}
Note: LineTraceRange = 100000;

AMyPlayerController_Class::getLookDirection(FVector2D screenCrosshairLocation, FVector worldLocation, FVector worldDirection)
worldLocation and worldDirection are supposed to be output parameters. You’re passing them by value which means the variables you pass in aren’t going to be modified at all, they need to be passed by reference.
Okay thanks for the solution ,I will keep that in my mind next time .
