ok, thanks! by the way, python2.6 won't let me change just one part of a tuple...

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

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)
