woow jeezes, thanks for the amazingly fast and detailed response, you guys are amazing.



let's clear a few things up :

1) points is a module in vpython to make points, the points do in fact appear although its not really the effect i intended to have, the points are "lined up" in stead of randomly separated, if you know what i mean

2) sorry for the dutch names :)

3) i put the parenteces there and then i got a bunch of errors which i fixed






2 problems:

a) my program seems to be stuck in the update phase of brandstoftank(=fuel tank), it doesnt get to the update of the spaceship

b) the problem i originally described in my first post was not resolved, by means of elimination i could conclude that the problem situates itself in this lines :

 if (s == "left"):
                self.gas = rotate(self.gas,angle = math.pi/10, axis = (0,0,1))
                c = list(self.frame.axis)
                c[2] -= 0.1
                c = tuple(c)
                c = self.frame.axis
            if (s == "right") :
                self.gas = rotate(self.gas,angle = -(math.pi/10), axis = (0,0,1))
                c = list(self.frame.axis)
                c[2] += 0.1
                c = tuple(c)
                c = self.frame.axis

i will put the full revisited code here :

thanks again, are you guys getting paid for this or is this voluntarily? either way i really appreciate it
