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.

Would this method work for multiple reverse wall checks?
