Logical Question

Is there any kind of bit operation or arithmetical trick that would allow me to do something like integerWhichCouldOnlyHaveAValueOfZeroOrOne == 0 ? otherIntegerWhichCouldOnlyHaveAValueOfZeroOrOne == 0 ? 0 : 1 : 2 without so many expensive conditionals?

Like this?

integerWhichCouldOnlyHaveAValueOfZeroOrOne | otherIntegerWhichCouldOnlyHaveAValueOfZeroOrOne + integerWhichCouldOnlyHaveAValueOfZeroOrOne

Yes, I think that would work.

Thanks

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?

Sheldor (talk)22:41, 25 June 2013

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.

Skilgannon (talk)22:47, 25 June 2013

Would this method work for multiple reverse wall checks?
