Hello, I'm currently porting a processing sketch into Eclipse, but I've run into some problems concerning accessing variables from other classes.
In my sketch, a global variable is declared before the setup method e.g.
int var1=123;
void setup(){
...
This variable can then be accessed by other classes by its name alone e.g.
class blah{
blahvar=var1;
}
Now in Eclipse, to do the same thing, do I need to declare the variable 'static' for it to accessable in other classes without having to refer to the object that contains it (whatever that is for the main class)?
Thanks,
Rob

The answer depends on the structure of your code: will the other classes be internal to the main class, like they are if they live in a .pde file? Will they be independent, as if they live in a .java file?
In the first case, NoahBuddy's answer applies, no prefix needed.
In the second case, you have to use an accessor (or make public) and in all cases you have to specify the class holding the variable, like you have to have a reference to PApplet to call Processing functions.

You are on the right track. Passing 'this' will give a reference to your sketch.

For your other class to access a variable, either the variable needs to be public (i.e. "public int var = 4;") or as PhiLho suggested, use an accessor.

An accessor is a public method that gives regulated access to a private variable. This way, the variable cannot be changed without you knowing it.
Code:

class mysketch extends PApplet {
  int var = 4;//private variable
  ...
  public int getVar() {//an accessor to read var
    return var;
  }

  public int setVar(int newValue) {//an accessor to set var
    var = newValue;
    return var;//to verify change
  }
  ...
