Multiple files and size()

nekketsuuu

If there are two or more files in one project and the second file has setup(), an error size() cannot be used here, see https://processing.org/reference/size_.html occurs. Is there any rules around the order of files when there are multiple files?

The details are as follows.

Environment

• Processing 3.3.3, PDE
• Ubuntu 16.10

Code

a.pde

class Foo {}

b.pde

void setup() {
  size(100, 100);
}
void draw() {
  background(0);
}

File order: a.pde, b.pde

Behavior

• After pressing "Run" button, the error size() cannot be used here, see https://processing.org/reference/size_.html occurs although the arguments of size() are constants.
• If the file order is b.pde, a.pde, the error doesn't occur.
• If I use settings() instead of setup(), the error doesn't occur.

This sounds like it relates to the preprocessor. Have you filed a bug report?

Also -- is your sketch folder named "a"? The name of your primary tab MyName corresponds to both the sketch folder name and the primary pde file --

/sketchbook/MyName/MyName.pde

So if you aren't doing that, that could be part of the problem.

Thanks for your reply!

Have you filed a bug report?

I filed a issue just now. https://github.com/processing/processing/issues/5065

is your sketch folder named "a"?

Yes.

Note: The problem is solved. According to @benfry, we must locate the setup() function in the main tab. So this is the problem of an error message. Details are here: https://github.com/processing/processing/issues/5065 .
