Yea... Jakes method would do.. or you can just simplify it spaceship_speed = 10
if keys[K_LEFT]: x_move += -spaceship_speed if keys[K_RIGHT]: x_move += spaceship_self.speed rect = rect.move(x_move, 0) BTW... spaceship.speed=(spaceship.speed[0]-10, spaceship.speed[1]) is unnecessary. No point in rewriting the whole list when your only changing one part On Thu, Apr 9, 2009 at 9:56 PM, Jake b <ninmonk...@gmail.com> wrote: > Print out .speed to see what the values are. > > example: in IDLE > > >>> from euclid import Vector2 > > >>> class Ship(): > def __init__(self): > self.speed = Vector2(0,0) > self.loc = Vector2(0,0) > def accel(self, xvel, yvel): > self.speed += Vector2(xvel, yvel) > def update(self): > self.loc += self.speed > def __repr__(self): return "s=%s, l=%s" % (self.speed, self.loc ) > >>> s = Ship() > >>> s > s=Vector2(0.00, 0.00), l=Vector2(0.00, 0.00) > > >>> s.accel( 10, 0 ) > >>> s > s=Vector2(10.00, 0.00), l=Vector2(0.00, 0.00) > > >>> s.update() > >>> s > s=Vector2(10.00, 0.00), l=Vector2(10.00, 0.00) > > >>> s.update() > >>> s > s=Vector2(10.00, 0.00), l=Vector2(20.00, 0.00) > > -- > Jake >
