Re: [pygame] circular movement in pygame

[Aleksandar Petrovic <aleksandar.petrovicvr@xxxxxxxxx>]

If you want update coordinate, new coordinate add on old coordinate not on center rect.


self.rect.x = self.radius * math.sin(self.angle) + self.rect.x

self.rect.y = self.radius * math.cos(self.angle) + self.rect.y

Looking at the code on this page lines 47 & 48

http://programarcadegames.com/python_examples/show_file.php?file=sprite_circle_movement.py

is there a way to doÂ

self.rect.x += some value

self.rect.y += some value

rather than

self.rect.x = self.radius * math.sin(self.angle) + self.center_x

self.rect.y = self.radius * math.cos(self.angle) + self.center_y




?

I tired it in the code attached and strangely it works ok but only OUTSIDE THE class. When I implement the exact code in a class it does something weird. I can't find where I have gone wrong.

Please help.

Many thanks in advance.
