Sorry I just realise that made not sense. I have created a program in python similar to battleships. I have created the class section which were working when I include the direction section in the main and not as a seperate method, However when I move the method into a seperate section and ask the function to be called, I cannot get my method to call into my main function now for the 2 ships to battle Can someone please tell me what I am doing wrong as I cannot get it working and am getting very frustrated....Thank-you

First, please use the [code="Python"] [/code] tags to enclose your code. That will preserve your indentation.

More importantly, your code:

The first thing that strikes me is that your Tank1() and Tank2() classes contain exactly the same code. Therefore, you don't need both. Instead, you can do this:

class Tank (object):
    def __init__(self):
        self.xcord = 0
        self.ycord = 0
        self.arm = 10
        self.fire = 1

    def GetX (self):
        return self.xcord
    def GetY (self):
        return self.ycord
    def GetArm (self):
        return self.arm
    def GetFire (self):
        return self.fire
    def SetX (self , move):
        self.xcord = self.xcord + move
    def SetY (self , move):
        self.ycord = self.ycord + move
    def SetArm (self , n):
        self.arm = self.arm + n
    def SetFire (self, n):
        self.fire = self.fire + n

...

def main():
    t1 = Tank()
    t2 = Tank()
...

Now, you have two discrete objects (t1,t2) that follow the same plan (class Tank). I think you were confusing the class with the actual object.

Second, I don't understand the purpose of the Direction class. It seems to me that the use for a direction is to tell the tank to move. But 'move' is a verb -- and therefore should be a method of the Tank() class.

That is, if your object can do action X (like "move"), then X should be a method of the class.

So something like this:

class Tank(object):

   ...

   def movetowards(self, target):
       """move self towards target"""
       if target.GetX() < self.GetX():
            self.SetX(-1)
       elif target.GetX() > self.GetX():
            self.SetX(+1)
       if target.GetY() < self.GetY():
            self.SetY(-1)
       elif target.GetY() > self.GetY():
            self.SetY(+1)

I don't know if that's exactly the behavior you want, but you can modify it to suit your game rules.

Speaking of game rules, I strongly encourage you to put the rules for the game to paper before you code them up. Doing so will help you be clearer about the code.
