Ok, I'm trying to make a simple game/program where you move a cat with the <^> and \/ buttons on your keyboard and then I'll have a Zombie that will chase the cat, once it catch the you (the cat) you will lose.

now my problem is I get the error saying like..
"Code takes excatly 2 arguments"

Also.. I drew a circle in the middle of the screen, the Zombie won't ever enter this area so basically this will be a safe spot for you (the cat).
I do not know how to make the zombie unable to go there nor how to make it chase you, I would know how to make it unable to go to the circle by controlling the cordinates but since it's a circle it'd take tons of cordinates unless I use derivata somehow but I don't remember how cause it's a long time ago I studied that in school.
please, help me someone.

Ok, sorry for being unclear.

Here is the error:
"Traceback (most recent call last):
File "C:\Python27\Cat game v2.2.py", line 47, in <module>
Funct=Thing.RESIZE()
TypeError: RESIZE() takes exactly 2 arguments (1 given)"


I tried this just now:
I removed Funct=Thing.RESIZE() from line 47 and now I managed to start the program, however when I click SPACE button it's supposed to double the size of cat.jpg (variable: mif) using the function RESIZE though, when I press SPACE the program crash/freeze so I need to exit it.

This is how my code looks like now... barely any difference though:

Your previous code didn't work because because you called RESIZE with only the self-argument, but you defined RESIZE to take two arguments. So a call to RESIZE should look like foo.RESIZE(bar), not just foo.RESIZE().

Your current code doesn't work because when the user presses spaces, you execute the line Thing(mouse_c). Since Thing is not a function (or an instance of a callable class), this does not work.

Wanted some..

anyhow, now I did some small changes and here's the error I got now after the changes

See my previous post re: Thing not being a function or callable object.

[s1mple]

Ok.. I don't quite get what you mean by "foo" or "bar".
I'm rather new to programming so I'm not familiar with most terms and such so please excuse my noobiness.

I got a question ..
since you say it's not callable. . How do I make it callable? I have the problem because I want it to take the values/arguments itself through the function, otherwise it would been easier.

So to call it I need something like I had before like this?
Funct=Thing.RESIZE()
and then later I call the Funct instead of "Thing".
Is that correct?

and by doing that I just do Funct() since I don't want any values/arguments only the ones in the function

    def RESIZE(self):
        a, b = mouse_c.size
        a*2, b*2
        mouse_c = pygame.transform.scale(mouse_c, (a,B)/>)

so basically I want to use the a, b (as in width and height) which I grab using the a, b = mouse_c.size ..
if you get what I mean?

They're just nonsense words that don't mean anything. I could just as well have written x.RESIZE(y), bla.RESIZE(blobb) or chunky.RESIZE(bacon). The point is: if RESIZE is defined to take two arguments, there needs to be something between the parentheses.

I think if I'd answer that, that'd just send you off in the wrong direction. I don't think making the object callable will get you where you want to go.

Quote

The point is you're not calling a function. There is no function involved when you write Thing(mouse_c) because Thing is not a function.

Funct=Thing.RESIZE()
and then later I call the Funct instead of "Thing".

No. If you want to call RESIZE on that line, you should write Thing.RESIZE(mouse_c).

[s1mple]

Ok, I really can't figure out how to make this work.
Could you please give me an example by writing the code out for me?
I tried lots of different ways but I cannot seem to do it properly.

Maybe you should start by writing more simple programs and learn the basics of functions and classes first. Because currently you're basically trying things at random and you don't really seem to get anywhere.

Well I find it easier to learn if I do something I enjoy and I don't really enjoy doing too easy programs.
I choose this one at a basic level then I improve it with ideas I come up with in time.

Like the zombie/scaling ideas.
Please, could you help me? It's easier for me to learn this way.

problem with that mindset though is you lose out on learning proper syntactical structuring that would aid you in understanding what exactly is going wrong and how to address the problem. However, I played with your code in couple ways as well, I can't seem to resolve the issue you are trying to address either. sepp2k is probably right, you need to start a little bit simpler or find some code someone else has done in a similar manner and try to absorb their process.
