Re: [pygame] Float precision

["Marcel Rodrigues" <marcelgmr@xxxxxxxxx>]

Hi. If you still have problens with precision, you may want to use round() before converting to integer:

                self.rect.centerx = int(round(self.xx))
                self.rect.centery = int(round(self.yy))

or just (with same results):

                self.rect.centerx = int(self.xx + 0.5)
                self.rect.centery = int(self.yy + 0.5)

Thanks John I will use this till I find a new solution

Yes I see this.
I think most of the problem is here

               self.rect.centerx += dx
               self.rect.centery += dy

maybe centerx and centery need to be integers?
I had better luck when I changed it to like this
               self.xx += dx
               self.yy += dy
               self.rect.centerx = int(self.xx)
               self.rect.centery = int(self.yy)
where self.xx and self.yy are floats.
It was still not perfect but much better than before.
