void Remove(const T* inValue)
{
int offset = inValue->x*MAXTILE_YLEN + inValue->z;
mbVisited[offset] &= ~(1 << inValue->direction);
Count--;
}
BYTE mbVisited[MAXTILE_XLEN*MAXTILE_YLEN];I want to clear the corresponding mbVisited bit based on the x,y and dir given as
the argument to Remove.
But I am not sure if this would work or not?
Thanks
Jack
I need to check it. But for the time being, it is working as normal.
But I am not sure, because I copy it off somewhere from the web.
You could verify the function by reading the documentation of the bitwise operators used therein, and testing it by feeding various values to it and comparing the returned values with known, expected values. It would also be a good chance to learn unit testing.
It is dangerous to use copy/pasted code in production projects, if you don't understand what it does. When stuff breaks, it is your fault, whether or not you understand why.
Unit tests are your friend. An important step when integrating 3rd-party code is to write unit/integration tests that ensure it does in fact work as you think it does.
