I have been playing with functions, and I have run into a problem I hope has a more graceful solution then the one I am using. My function creates a bitmap, draws on it using parameters passed to the function, gets the image, and makes a sprite.

But if I try to call it more than once, since it uses the same image number etc to make the sprite, I get unfortunate results. I fixed it by requiring a unique name to be passed each time it is used, but I would rather the function itself choose a special name each time it's used. I thought of using the timer but hoped there was a better way.

Any ideas? I've included a short example in case my description was confusing, just remove the last parameter of the MakeButton() function and function calls to see the problem

You want to change the value of the image number within the function, each time the function is called?

To do that, you would need to define the variable as global (outside the function), then increase it by one within the function. Something like this:



This makes the function increase the value of the image number and display it on the screen each time you press a key. (Note that you can't include the global variable as an argument of the function.)

Thanks!

That's approximately what I ended up doing, but I'm still unhappy. I'm thinking about parsing the timer() to get separate names, that way the function will be more "plug and play". So far my attempts have really slowed down the fps. Probably redundant loops.
