I'm trying to import a shape and the shape is just a simple a circle really, but I get this error message:

parsed: m,605.71429,475.21933

unparsed: a,237.14285,211.42857,0,1,1,-474.2857,0,237.14285,211.42857,0,1,1,474.2857,0,z

What is issue #130? I have the latest version of Processing (1.5.1) What's going on?

I am building a game in processing where a user has to use a light, pointed at a webcam, to guide a ship to a lighthouse while dodging buoys and whales. I need help setting up the ship class to follow the brightest pixel on the screen.

My issue is, It works without the ship being called as an instance, but I need it as an instance of the ship class to calculate the collision detection I need for the buoys and whales whenever they come in contact with the ship.

Whenever I try to pass through arguments I need through my ship class, The instance of the ship only runs once and does not continue to track the brightest pixel on the screen.

I'm stuck because I don't know how to set it up, do I need to pass values through the constructor or leave the function of brightness tracking inside the draw function? Here is my code, and I appreciate the time and effort to help me. (the commented parts are where I tried to implement the ship as a class, but if they're commented out it will work just fine)

//main code

import processing.video.*;

PShape s;

Capture video;

Lighthouse myLighthouse;

Whale [] whaleCollection = new Whale[7];

Buoy [] buoyCollection = new Buoy[23];

//Ship myShip;

void setup()

{

size(800, 600);

video = new Capture(this, width, height, 60);

noStroke();

smooth();

s = loadShape("ship2.svg");

//myShip = new Ship (brightestX, brightestY);

myLighthouse = new Lighthouse(500,400);

for( int i = 0; i < whaleCollection.length; i++){

whaleCollection[i] = new Whale(random(0, width),random(0, height));

}



for( int i = 0; i < buoyCollection.length; i++){

buoyCollection[i] = new Buoy(random(0, width),random(0, 400));

}

}

void draw()

{

if(video.available())

{

video.read();

//video.loadPixels();

background(23,194,219);

//myShip.run();

myLighthouse.run();

for( int i = 0; i < whaleCollection.length; i++){

whaleCollection[i].run();

}

for( int i = 0; i < buoyCollection.length; i++){

buoyCollection[i].run();

}



int brightestX = 0;

int brightestY = 0;

float brightestValue = 0;





video.loadPixels();



int index = 0;

for(int y = 0; y < video.height; y++)

{

for(int x = 0; x < video.width; x++)

{



int pixelValue = video.pixels[index];



float pixelBrightness = brightness(pixelValue);



if(pixelBrightness > brightestValue)

{

brightestValue = pixelBrightness;

brightestY = y;

brightestX = x;

}

index++;

//myShip.run();

}

}



//fill(255, 204, 0, 128);

//ellipse(brightestX, brightestY, 50, 50);

shape(s,brightestX, brightestY, 100, 100);

//myShip.run();

}

}

//Ship Class

class Ship{

float x = brightestX;

float y = brightestY;

//float brightestX = 0;

//float brightestY = 0;

//float brightestValue = 0;

PShape s;





Ship(float _x, float _y){

x = _x;

y = _y;

s = loadShape("ship2.svg");

}







void run(){

//brightnessFunction();

display();



}





void display(){



shape(s,x,y, 80, 80);

}
