I am making a Java Processing project in Processing IDE and would like to spread it across multiple PDE (Processing Source Code) files.
I am unable to import Java Processing Source Code file as a Java class file using import.
config.pde
public int screenWidth = 750;
project.pde
import project.config;
// OR
import project.config.screenWidth;
// OR
import config;
// OR
import config.screenWidth;
returns The import project/config cannot be resolved. respectively.
Do I have to compile PDE files first? Can I set up the Processing IDE to do it automatically for every run?
TLDR;
Having this project folder:
|project
|--project.pde
|--config.pde
How do I use functions and variables from config.pde in project.pde?
In general:
The Processing IDE may support multiple tabs but these do not behave like Java classes: every tab is a member of the same higher-level class behind the scenes. As a result, all members from all tabs share the same scope and a tab that declares a given primitive, object, method or class needn't be referenced when another tab accesses a member from it.
For this reason, declaring a member private in one tab will not reduce accessibility of it in other tabs; every declaration is effectively public, for they reside within the same outer-class scope.
import is only required when you wish to introduce and reference external libraries.
In your project:
Simply refer to screenWidth within the project.pde tab to access it. The same can be said for any methods you wish to reference between tabs.
