Call variables from other methods
Nov 28th, 2007, 8:36pm  
Hello everybody!

I'm just learning the basics of programming and i'm really lucky to see what is possible with processing.
While i'm waiting for my handbook get's shipped from the US, i have to ask a very basic question here:

I try to access a variable which is defined in a other method and Processing still gets me error messages like: "No field named "test" was found...)

Basically i try to check my Mail account with the Java mail library and call the method "checkMail()" from the "draw()" method. So far, so good. But i want to access all the variables inside of checkMail() - how is this possible?


Thanks in advance

If you're asking what I think you are, you can't.

You can only access things which the object makes available in some way.

For example:

Code:

int funcA()
{
  int wibble=3;
  // do stuff;
  return 0;
}

int funcB()
{
  return wibble; // this will not work, since wibble is:
  // a: resricted to the funcA function only
  // b: temporary. It only exists whilst funcA is running
}

Thanks for your fast reply. I defined the variables to fill in the main program now and filled them in the function. Nice!
