If there is no possibility that
integerWhichCouldOnlyHaveAValueOfZeroOrOne == 1 and
otherIntegerWhichCouldOnlyHaveAValueOfZeroOrOne == 0, or if you don't care, then a simple addition would work.
If you're using it for wall segmentation, it should be fine just adding. The chances of the closer one being triggered but not the further is quite rare (although it can happen, I admit).
If both wall checks be either 1 or 0 at the same time a vast majority of the time, what's the point of even having a second wall check?
Hang on, is this two forward wall checks, or one forward and one reverse?
I was thinking two forward, where obviously the check which extends further will also be triggered in 99% of cases where the one that extends less is triggered.
If this is one forward, one reverse then I think they should actually be in different segments.
