Poor performace when rewritten into a class.
Jan 8th, 2008, 1:02pm  
I'm having some troubles with something that works as a standalone program but when put inside a class it slows down incredibly, obviously there's something wrong with the code, something that probably repeates into infinity... but I can't find it.

/**
 * Seaweed object
 *
 */  
public class weed{
 //vars
 float inc = 0.0;
 int x, vUnits;
 float angle;
 int hSize, vSize;

 /**
   * CONSTRUCTOR
   * Draws at the bottom of the screen,
   * iX, horistontal position of the object.
   * ivUnits = number of units inside each object, the more units the higher the object.
   * ihSize, horisontal size of the drawing screen.
   * ivSize, vertical size of the drawing screen.
   */
 weed(int iX, int ivUnits, int ihSize, int ivSize){
   x = iX;
   vUnits = ivUnits;
   hSize = ihSize;
   vSize = ivSize;    
 }
 
 /**
   * Update/draw method.
   */
 void update(){
   stroke(0xCC99FF66);
   smooth();    
   
   inc += 0.01;
   float angle = sin(inc)/10.0 + sin(inc*1.2)/20.0;    
   pushMatrix();
   translate(x, vSize);    
   for(int i = vUnits; i > 0; i--){    
     strokeWeight(i);
     line(0, 0, 0, -8);
     translate(0, -8);
     rotate(angle);
   }
   popMatrix();
 }
}

can you post all of your sketch? how many weeds are you drawing?

this runs smooth on my MacBook Pro at 60fps:

Quote:


import processing.opengl.*;

ArrayList weeds = new ArrayList();
PFont font;

void setup() {
 size(1000,200, OPENGL);
 frameRate(999);
 font = createFont("Courier", 12);
 textFont(font);
 //strokeJoin(MITER);
 for (int i=0; i<250; i++) {
   weeds.add(new weed((int)random(width), (int)random(2,20), width, height));
 }
 smooth();
}

void draw() {
 background(0);
 for (int i=0; i<weeds.size();i++) {
   ((weed)weeds.get(i)).update();
 }

 fill(255);
 text("fps: " + frameRate, 10,10);

}

/**
* Seaweed object
*  
*/
public class weed{
 //vars
 float inc = random(5.0);
 int x, vUnits;
 float angle;
 int hSize, vSize;

 /**
  * CONSTRUCTOR
  * Draws at the bottom of the screen,  
  * iX, horistontal position of the object.
  * ivUnits = number of units inside each object, the more units the higher the object.
  * ihSize, horisontal size of the drawing screen.
  * ivSize, vertical size of the drawing screen.
  */
 weed(int iX, int ivUnits, int ihSize, int ivSize){
   x = iX;
   vUnits = ivUnits;
   hSize = ihSize;
   vSize = ivSize;    
 }

 /**
  * Update/draw method.
  */
 void update(){
   stroke(0xCC99FF66);
   //stroke(10,200,100);

   inc += 0.02;
   float angle = sin(inc)/10.0 + sin(inc*1.2)/20.0;    
   pushMatrix();
   translate(x, vSize);    
   for(int i = vUnits; i > 0; i--){    
     strokeWeight(i/2.5);
     line(0, 0, 0, -12);
     translate(0, -8);
     rotate(angle);
   }
   popMatrix();
 }
}

I think I found the issue, might have had to do with a new background image that was missbehaving.

Thanks for the help though, reminded me how to write a few things better. =)
