Re: [pygame] car game mechanics

Yeah indeed it works for the rotation but the movement are not realist at all the way i did. I found this on the internet :

http://engineeringdotnet.blogspot.com/2010/04/simple-2d-car-physics-in-games.html

it's illustrated by C++ example so i would like to know if there is an equivalent class to the Vector2 C++ class? Or maybe can i just a numpy array instead?

You already have self.angle.  Why not just do your transform as a function of that?

a_deg = self.angle % 360

sprite = pygame.transform.rotate(self.original, a_deg * -1)

Doing something like :

a_rad = math.atan2(speedy, speedx)

?

I can turn 360 degrees yeah but it does not make proper rotation... i ll try to find something on the internet about 2d car physics.

Try math.atan2, feeding it both the x and y components of the velocity.
