I'm writing a little game in cocos2d, trying to use the Bezier Action
and Bezier path to make a Missile fired from a Capitol Ship the
missile fly at the Mother Ship in a cool, loopy kinda way.
My problem seems to be what I think is a position isn't what Bezier
thinks is a position. I give it the Mothership position, and the
Missile starting position (wherever its Capitol Ship is at the time) ,
and tell the Missile to make it's way to the Mothership.
However, the Bezier Path seems to think 0, 0 is where ever the Missile
has spawned, not absolute position on the screen.
How can I get the Bezier Path to take absolute position? Here's the
bit of code from the Missile class
def hitTarget(self):
tx, ty = self.target.position
mx, my = self.position
# this bit of code makes the missile do weird things
# path = BezPath( (mx, my), #first point
# (tx, ty), #end point
# (mx-10, my-20), #second point
# (mx-20, my-30)) #third
#this bit of code makes the Missile spawn correctly, but will I have
to calculate the relative position
#of the mother ship to make it hit?
path = BezPath( (0, 0), #first point
(0, 0), #end point
(-10, -20), #second point
(-20, -30)) #third
self.do(BezAction(path, 2 ))
