Issues with GetActorForwardVector
I seem to have encountered and unexpected behavior of the I'm checking to actors forward vector against one another, and I'm noticing that one actors forward vector looks like this: Is there a way for me to force the 0's to be positive, as I'm only interested in the 1's? :)

To see if they are facing each other, do a dot product of the two vectors instead This way you get a single value to compare and is more manageable. If both the actors face the same way, the value will be close to 1. If it is close to 1, they are facing away from each other. If it is 0, they are perpendicular So if the dot product is:
An important thing to note is before the dot product is done, the two vectors need to be normalized Using the dot product actually solved my problem. Thank you for your answer. In case someone was wondering, it's possible to get the dot product from an

The issue of 0 is a complex one. What do you need to use the numbers for? It might not be necessary to change the values at all depending on what you are trying to do. 0 is the same value as 0 when used in Vector operations.
I don't need the 0's I only need the 1's (getting the forward AXIS). So in this specific scenario, I have no use for the X axis, only the Y. Problem is of course, that the first vector is not equal to the second, since the X is negative/positive. I only need the value of the Y axis, but it might as well could've been the X axis. It's just the Y axis in this example.
