Hi!

I'm a new user of Processing and (after 1 second), i've got a problem!

I want to draw a circle using the ir spots of the Led Bar. I've taken this code using the osc p5 with a sketch found in this forum.

This is my code:

import processing.opengl.*;
import javax.media.opengl.*;
import javax.media.opengl.glu.*;


WiiController wiiController;


static final int MAX_SIZE = 15;

GL gl;
PGraphicsOpenGL pgl;
Point currPoint;

float w = 400;
float h = 400;
float wn = 400;
float hn = 400;
float newH = 100;
float newW = 100;
float newHn = 100;
float newWn = 100;


int ledCnt = 0;
 
void setup() {
 size(1280,1280,OPENGL);
 pgl = (PGraphicsOpenGL)g;
 gl = pgl.gl;
 frameRate(25);
 noStroke();

 wiiController = new WiiController();
 rectMode(CENTER);
}

void mousePressed() {

 wiiController.requestBatterylevel();

 
}

void irEvent(float x1, float y1, float s1, float x2, float y2, float s2, float x3, float y3, float s3, float x4, float y4, float s4) {

if ((s1 > MAX_SIZE) || (s2 > MAX_SIZE)) {

// IR point is not available
return;
}
}

void keyPressed() {

 ledCnt++;
 ledCnt %=4;
 int[] t = new int[] {
   0,0,0,0  };
   t[ledCnt] = 1;    
   wiiController.led(t);

}
void draw() {
   fill(0,10);
 rectMode(CORNER);
 rect(0,0,width,height);

 stroke(266); {
    fill(200, 800, 0, 70);
   ellipse (currPoint.x, currPoint.y, 100, 100);
 }
}


but this part became yellow :
  ellipse (currPoint.x, currPoint.y, 100, 100);

and then i've this error message: NullPointerException.


Can you help me????

Bye!

Gio
