I think this is what is happening...
- If it is less than the destination you add to it, and then see if you
added too much, in which case you try to set it to the final location.
- Eventually you will get to the destination. The locH will be equal to
the destination.
- Since it is EQUAL, it will fail the first 'if', which sees if it is <.
- Since it failed, it will go to your unconditional else, which
automatically adds some pixels on. Remember that you are ALREADY at the
destination so you don't want to add pixels, but you are.
- The next line checks to see if you are <= the destination (which you are
not, since you were adding). It might have corrected, but it won't, since
you are past the destination already.
You could probably correct this by changing the unconditional else to be a:
else if (sprite(me.spritenum).loch > pDestination)
which means that if it's < then you add, and if it's > then you subtract,
but if it's = then you leave it alone.
