Can we keep conversations open a little longer?

the thread closed before I could ask…

Advantages of Mutating a value rather than returning the value

No, FVector’s constructor doesn’t initialise it’s members. The reason that was done is because we want success/fail return. An alternative way (and one that would probably be used in the remaster) would be to use an optional type (std::optional /TOptional) So instead TOptional<FVector> GetSightRayHitLocation() const; //////////////// auto Value = GetSightRayHitLocation(); if(Value.IsSet()) { //Do something with Value.Get() }

wanted to say that if it doesn’t return zero vector it would return a null? so not safe to use which the optional would wrap in something to protect against calls to undefined?
