I have create a project processing with the IDE Eclipse and my files are on .java format.
Now, I want to use the IDE Processing for this project.

Is it possible to "convert" .java to .pde ?

Problem launching application on Linux

Hello everybody,
I have developed an application in eclipse in Windows using the processing libraries.

I have a processing class which contains the following:
2. package test3;
4. import processing.core.PApplet;
7. public class Test3 extends PApplet {
8. public void setup() {
9. size(280,200);
10. text("test", 10, height/2);
11. noLoop();
12. }
14. static public void main(String[] passedArgs) {
15. String[] appletArgs = new String[] { "--full-screen", "--bgcolor=#666666", "--stop-color=#cccccc", "test3.Test3" };
17. }
18. }
I have export this application : Project -> Processing Export (Output : Application)

My application work's fine on windows but when I launch the application on Linux
1. java -cp lib/core.jar:lib/Test3.jar Test3
I have an error :
1. Exception in thread "main" java.lang.NoClassDefFoundError : Test3
2. Caused by: java.lang.ClassNotFoundException : Test3
3. ...
4. Could not find the main class: Test3. Program will exit
To verify that i can execute a processing application on linux, I have write too an application on windows with the IDE processing and after export, I have launch it on linux and it's work fine.

It seems that is my export on eclipse which don't work but I don't understand why.

After the export I have these files :
- application.linux
And Test3 :

#!/bin/sh

APPDIR=$(dirname "$0")

java -Djava.library.path="$APPDIR" -cp "lib/Test3.jar"test3.Test3

function interrupt draw

I have create an application which read a video and where the speed can be modified by event "keyPressed".
This works well but when I press several times the key, the method draw seems stop and my movie in pause until the event endding.

How to solve this problem of interrupt ? How I can reduce the time of the interrupt fonction ?

This is my sketch :
2. import processing.video.*;
3. Movie mov;
4. float speed;
6. void setup() {
7. size(480, 390);
8. frameRate(50);
9. mov = new Movie(this, "myvideo.mov");
10. mov.play();
11. speed=0.5;
12. }
14. void draw() {
15. background(255);
16. fill(255);
17. mov.speed(speed);
18. image(mov, 90, 90, 390, 390);
19. fill(0);
20. text( "speed : " + speed, 10, 30);
21. if((mov.duration())-(mov.time())<0.1 && speed>0){
22. println("fin video "+mov.time()+"mov.duration : "+(mov.duration()));
23. mov.jump(0);
24. }
25. if(speed<0 && (mov.time()-0)<0.1){
26. println("fin video "+mov.time());
27. mov.speed(abs(speed));
28. mov.jump(mov.duration());
29. }
30. }
32. // Called every time a new frame is available to read
33. void movieEvent(Movie m) {
34. m.read();
35. }
37. void keyPressed() {
38. if (key == CODED) {
39. if (keyCode == LEFT) {
40. speed = speed -0.1;
41. } else if (keyCode == RIGHT) {
42. speed = speed+0.1;
43. }
44. }
45. }

Hi,
I want automate my test of processing. For this, I simulate the behaviour of the mouse and keyboard with Robot class.

The problem is that the event doesn't trigger the function mouseMoved().
2. import java.awt.AWTException;
3. import java.awt.Robot;
5. Robot robot;
7. void setup() {
8. size(400, 400);
9. try {
10. robot = new Robot();
11. }
12. catch (AWTException e) {
13. e.printStackTrace();
14. }
16. }
18. void draw() {
19. if (frameCount 0==0){
20. robot.mouseMove(100, 100);
21. println("fin draw");
22. }
23. }
25. void mouseMoved(){
26. println("mouve OK");
27. }
What is the problem ?
there is an other way to automate test ?

Hi,
I have create a Processing application. I want now create unit test to automate tests.

I have import (without problem) my project on Eclipse. Indeed, i think that it's a good idea to use Junit test.

The problem is that I have no idea how I can create test on my class (extends PApplet).

Is it Junit is a good idea or I completely wrong ?

is there any tutorial about test of processing ?

Are you some tracks to help me

Thank you for your help
