Re: Help with two issues, buttons and second class object
Also I am struggling to understand: def move_tank(self, dx, dy): self.x += dx self.y += dy self.canvas.move(self.id, dx, dy) Where does the dx and dy values get input? -- https://mail.python.org/mailman/listinfo/python-list
Re: Help with two issues, buttons and second class object
Peter, in your code what does that self.root = root mean in the __init__ function of the class -- https://mail.python.org/mailman/listinfo/python-list
Re: Help with two issues, buttons and second class object
Wow thankyou that code is really good, I had no programming knowledge until 2 months ago, I enjoy your descriptions it is really helpful for me. I like to understand what the code does before using it myself or a variant of it. Will tweak bits tonight the project is in tomorrow. This code is just a side to the one I completed and will be handing in so im just doing this for fun and learning but the past months but as I learn new things I keep wanting to rebuild my program. I will be adding obstacles into the code too and eventually enemies, that explains the commented out code for attack and medic. I will upload the code when I am done with it or get stuck again to see what your feedback is :D -- https://mail.python.org/mailman/listinfo/python-list
Help with two issues, buttons and second class object
Hi I have created some code, which moves a rectangle around and when it hits
the edge it picks a random new direction. It does this by the count function
within my class. I am wanting to create a button to randomly change count but I
my class seems to be getting errors.
I also wanted to create a second class object tank2 but it doesn't seem to move
when I create it with tank2.Tank(x,y,vx,vy) and call tank1.move()
Can anyone help me many thanks.

Thankyou for all your help I have managed to pick a way that works from your suggestions :D -- https://mail.python.org/mailman/listinfo/python-list

Random number help
I need a way of generating a random number but there is a catch: I don't want to include certain numbers, is this possible? random.randint(1,100) works as it will randomly pick numbers between 1 and 100 but say i don't want 48 to come out is there a way of doing this. It needs to be an integer too so not a list unless there is a way to convert list to int Many Thanks Tom -- https://mail.python.org/mailman/listinfo/python-list
