Processing 'It looks like you're mixing “active” and “static” modes.'

Question

Processing keeps giving me this error when I run it even though it is just a print command. When I delete the comment block it works fine. Here\'s the code:

Answer 1

The message could be shown when the actual problem is a syntax error. I encountered this error with the following (silly) code:

boolean state = false;

setup() {
  size(200, 800);
}

void draw() {
}

It is missing the 'void' modifier for the setup function. This is a syntax error (at least, it should be). But the Processing IDE gives you this "active vs. static" message instead.

So in this case, it should be void setup() { } rather than just setup() { }.
