Theres also eclipse. However this ide requires java syntax as opposed to processing syntax to run the code. And all new java files must use the processing import.
I also like VScode!
you also have to add the processing core.jar file to the project folder and add to the build path.
usually found in
C:\Program Files (x86)\processing\core\library
the jar file can be added to the project folder with a simple click and drag operation.
You must then add the file to the build path.
right click on the file will give you this option.
Here is a template for an eclipse project, be sure to rename the important parts to what you want the name of your sketch to be.
package testBench;
import processing.core.PApplet;
public class MySketch extends PApplet {
public void settings() {
size(500, 500);
};
public void draw(){
background(64);
ellipse(mouseX, mouseY, 20, 20);
};
public static void main(String[] args) {
PApplet.main(MySketch.class.getName());
}
};
