Vector Equals in c++

Development Programming & Scripting

Hi,

I’m currently transforming most of my bp to c++.
I got stuck on some point and I cannot find out what I’m doing different then in the blueprint.
I want to know when my player character is close to the enemy which is possessed by the AIController.
But when I’m transforming the bp to c++ the condition always fails, but in BP it is working, so I think I missed something here

Here is my c++ code

    float maxTolerance = 130.0f
	bool nearEnough = false;
	APlayerController* playerController = UGameplayStatics::GetPlayerController(GetWorld(), 0);
	FVector aiPawnVector = aiController->GetControlledPawn()->GetActorLocation();
	FVector enemyVector = playerController->GetControlledPawn()->GetActorLocation();
	nearEnough = aiPawnVector.Equals(enemyVector, maxTolerance);

Here is the BP logic which works fine

Thanks for pointing me in the correct direction :slight_smile:

EDIT
First post was confusing because I had different float tolerance accidently. this was a typo.
I just want to convert exactly the same from bp to c++

Best

You want it to be closer than 150? Then try the following:

nearEnough = (aiPawnVector.DistSquared()) < (maxTolerance * maxTolerance);

hi,

thanks for the quick reply.

no I just want exactly the same behaviour I already have in my bp logic, with the same error tolerance.
but this is somehow not working

Your code looks correct. Debug output the vectors and try to get all components closer than maxTolerance to each other.

you have an static function on c++ FVector::Equals(your vector, tolerance).
So would be something like :
MyLocation.Equals(EnemyLocation, 1.0f) → this gonna return a true or false result.
