                Steps to follow for using shaders in OpenFrameworks v0.9.8
              
          
    #General rules for working with shaders in OpenFrameworks

in main.cpp, set the GL version to 3,2:

  ofGLWindowSettings settings;
	settings.setGLVersion(3,2);
	ofCreateWindow(settings);


in ofApp.h, declare your shader member variable:

  ofShader shader;


## Ball.h
#include "ofApp.h" //include ofApp so you can use OF defined functions and vars
class Ball {

  public:
    Ball();//constructor
    ~Ball();//destructor
    //current ball position, you'll need to initialize
    //this somewhere in your constructor or another method
    ofVec2f mBallPos;
    bool checkIntersects(const ofVec2f &positionToCheck);

## Sailboat.sail.js
Sailboat.prototype = {
    constructor: Sailboat,
    sail : function(){
    if(this.xpos > width)
    {
      this.xpos = -200;
      this.ypos = random(height);
    }
    this.xpos = this.xpos + this.speed;
  }

## particles-example.js
var particles = [];
function draw(){

for (var i = 0; i < particles.length; i++) {
  //render your elipse with particle properties as x and y values
  ellipse(particles[i].positionX, ...);
};

}
