Struggling with Local Variables

Hi all,

I'm working on a very simple project, trying to get the hang of BM. One thing I'm really struggling with is the use of local variables.

Say I want to gently fade in the alpha from 0 to 1 via an if then loop such as:

If fade<1 Then
fade:+0.02
End If
SetAlpha fade

And this is itself within part of the main loop, where do I declare the 'fade' variable? If I declare it within the loop, it 'resets' to 0 everytime it's declared.

I can get around it via global variables, but surely this isn't the way to do it efficiently?

Cheers!

You could declare it before the loop, or you could create a type that handles this kind of effects.
I don't think there are other ways to do it (I could be wrong though).

Stick it in a function/method and label it global.
That way it will be "global" to the function/method, and the value will be kept between each call, but it won't be visible from the main loop..

Ah, didn't think of 'globalising' it within a function. I like to 'compartmentalise' all my work into functions, so this'll be ideal.
