OscControllerKit
Together with Paul Vollmer I created a library which simplifies the usage of a Nintendo WiiMote + Nunchuk and 3Dconnexion SpaceNavigator. We adapted the Processing API as much as we could to make using a controller as easy as using keyPressed() and mouseMoved().

Dependencies
- OSCulator (Mac OS X only)
- oscP5
Download the lastest release here.

The source code is hosted on Github. If you have any ideas which controller should be added, let us know! The next release will include the Apple Magic Trackpad .

WiiMote + Nunchuk Functions

Button imput

void wiimoteButtonPressed(int wiiNumber, WiiButton button)

void wiimoteButtonReleased(int wiiNumber, WiiButton button)

void nunchukButtonPressed(int nunchukNumber, NunchukButton button)

void nunchukButtonReleased(int nunchukNumber, NunchukButton button)

Sensor input

void wiimoteSensorChanged(int wiiNumber, float pitch, float roll, float yaw, float accel)

void nunchukSensorChanged(int nunchukNumber, float pitch, float roll, float yaw, float accel)

void nunchukJoystickChanged(int nunchukNumber, float x, float y)

Turn WiiMote LEDs on/off

void led(int wiiNumber, boolean led1, boolean led2, boolean led3, boolean led4)

Turn WiiMote vibrator on/off

void vibrate(int wiiNumber, boolean b)

Vibrate for a certain time

void vibrateForMillis(int wiiNumber, int millis)

Space Navigator

Button input

void snButtonPressed(int snNumber, SpaceNavigatorButton button)

I used the "send me a mail on new topics" feature to get informed about what's happening here. I had to disable it because of the mass of recent spam topics. Can you implement a capture validation when creating new topics? Would be very helpful!

Here is a temporary fix for PeasyCam on Windows with Processing 2.0b7.
If you are having problems with the official version, you can try this until there is an official release.

Download PeasyCam.jar from GitHub

jeff_g's fix seems to be the best option at the moment. Download here

Event handling in Processing 2.0b7

Forum: Core Library Questions

I don't find a possibility to check the state of a mouse event. Registering works using

registerMethod("mouseEvent", this);

But I did not find a solution to check the event type, which is defined like this:

public class MouseEvent extends Event {

  static public final int PRESS = 1;

  static public final int RELEASE = 2;

  static public final int CLICK = 3;

  static public final int DRAG = 4;

  static public final int MOVE = 5;

  static public final int ENTER = 6;

  static public final int EXIT = 7;

In earlier Processing versions, I could do a check like:

 switch (event.getID()) { case MouseEvent.MOUSE_PRESSED:

which is not possible any more. Only thing I can get is

e.getNative();

This object is decribed like this:

Get the platform-native event object. This might be the java.awt event on the desktop, though if you're using OpenGL on the desktop it'll be a NEWT event that JOGL uses. Android events are something else altogether. Bottom line, use this only if you know what you're doing, and don't make assumptions about the class type.

So it seems not to be the best solution to use... Any ideas?

Ghost Processing library - easy transparent window creation

Ghost is a mini Processing library which makes it easy to create transparent windows without any decoration. It will look like your sketch is running on the desktop.

There are three different modes:
- WindowedGhost: specify the width / height and position of the transparent window
- StickyGhost: sticks to one side of your screen with a specific width / height
- FullscreenGhost: creates a transparent window which goes all over the screen
You only need one line of code to create e.g. a transparent fullscreen window:
1. import de.timpulver.ghost.*;
3. void setup(){
4. new FullscreenGhost(this);
5. }
Tested on OS X Lion and Windows 8.

You have to install the latest Processing beta and at least Java 1.6_10 to use this library ( minimum 2.0b6).

Currently the renderers P2D, P3D and OPENGL are not supported.

How to remove the window drop shadow on OSX?

Anyone knows how to remove the window drop shadow of a Processing / Java application in OSX? For JFrames it should work like this
1. JRootPane root = getRootPane();
2. root.putClientProperty( "Window.shadow", Boolean.FALSE );
Any ideas on how to do this with an AWT Frame?

Is there a possibility to mark questions as answered? Saw the question about this several times on the board.
If there is no such possibility, you could make a sticky thread which encourages users to rename their threads after being answered to "[ANSWERED] Thread title".

[Solved] keyPressed() not working in Eclipse

Just stumbled upon a strange problem: The function keyPressed() is not getting called when using Eclipse.

My class looks like this:
1. package MyPackage;
2. public class MyClass extends PApplet{
3. public static void main(String[] args){
4. PApplet.main(new String[] {"MyPackage.MyClass" });
5. }
6. @Override
7. public void setup(){
8. println("println working");
9. }
10. @Override
11. public void keyPressed(){
12. println("println not working");
13. }
14. }
Anybody can help me? I'm really confused right now...

Thanks,

Tim

TroveP5 - a library to support int and float in ArrayLists and HashMaps

[2 Replies]
- 13-Jul-2012 02:29 PM
- Forum: Library and Tool Development
TroveP5 is a wrapper for the java library Trove, which is much faster, than using ArrayLists, HashMaps or LinkedLists.

For example you may want to store several int values in an ArrayList:
1. ArrayList al = new ArrayList();
2. al.add(42);
3. int a = (int)al.get(0); // ERROR: Cannot cast from Object to int
For this to work, you have to use:
1. ArrayList<Integer> al = new ArrayList<Integer>();
2. al.add(42);
3. int a = al.get(0);
The problem here is, that all values are stored as Integer Objects ( Integer != int ). If you have a lot of values, this is really slow. Instead you can use the Trove equivalent, which will be much faster! If you want to see how much faster it is, have a look at the benchmark.
1. TIntArrayList al = new TIntArrayList();
2. al.add(42);
3. int a = al.get(0);
From the origianal website:
The Trove library provides high speed regular and primitive collections for Java.

The GNU Trove library has two objectives:

Provide "free" (as in "free speech" and "free beer"), fast, lightweight implementations of the java.util Collections API. These implementations are designed to be pluggable replacements for their JDK equivalents.

Provide primitive collections with similar APIs to the above. This gap in the JDK is often addressed by using the "wrapper" classes (java.lang.Integer, java.lang.Float, etc.) with Object-based collections. For most applications, however, collections which store primitives directly will require less space and yield significant performance gains.
