Short presentation on how to use processing in intellij.

1. USING PROCESSING FROM
INTELLIJ IDEA

2. Start a new intellij project

4. Name your project

5. Nothing to do here, just click Next

6. First time you create a new project in Intellij
you have to select a JSDK

7. Click „New“ and select JSDK

8. Its a bit strange cause there is nothing to select,
but just click choose

9. Click Finish

10. Now add processings core.jar to your project.
File→Project Structure

11. Create a new global library

12. Click „Attach Classes“and choose the path to processing app.
Note on mac you can navigate inside the .app file

13. Now write your sketch. Create a new class in your src folder.
Right Click on your source folder.

14. Start writing and enjoy auto complete while typing

15. Code suggest

17. Run your sketch

19. Create the data folder in the root of your project.
Right click on the root folder →New →Directory

20. Basic sketch skelleton
import processing.core.PApplet;
public class Sketch1 extends PApplet {
public void setup() {}
public void draw(){}
}

21. Wanna have fullscreen mode?
static public void main(String args[]) {
PApplet.main(new String[] { "--present",
"yourPackageName.yourClassName" });
}

22. Some differences from processing
color cl = color (255, 0, 0);
becomes
int cl = color (255, 0, 0);
float f = 1.2;
becomes
float f = 1.2f;
mouseMoved(){}, draw(){}, keyPressed(){} etc.
becomes
public mouseMoved(){}, public draw(){},
public keyPressed(){}

23. Need another library
Download and unzip the library
Choose File→Project Structure
Same way as adding processings core.jar

24. Using OPENGL
Add opengl.jar, jogl.jar and gluegen-rt.jar like the core.jar
Note, On OSX the libraries are located at:
Processing.app/Contents/Resources/Java/libraries/opengl/library
Copy them to a folder of your choice.

25. Add
-Djava.library.path=Path/toThe/opengl.jarFile
to the VM Parameters

26. Got java.lang.OutOfMemoryError: Java heap space
Add
-Xmx1024m
to the VM Parameters
