Problem ! cant display more than 1 object
May 7th, 2009, 4:31pm  
Hi,

i cant find the error in the following program. I wrote a class and i want to creat 2 objects from this class that behave the same way but havent the same size an postiton.
Unfortunatly only one of the objects is displayed. I hope anyone can help me here and find the failure.

the program:


Zoog zoog1;
Zoog zoog2;

void setup(){
 size(400,400);
 smooth();

 zoog1 =  new Zoog(100,100,60,60,16,125);
 zoog2 = new Zoog (50,50,60,60,16,231);
 
}
void draw(){

 float kanne = constrain (mouseX/10,0,7);
 float nalos= zoog1.augenfarbe();

 zoog1.drawZoog(nalos);
 zoog2.drawZoog(nalos);
 zoog1.jiggleZoog(kanne);
 zoog2.jiggleZoog(kanne);
}

and here the class:

class Zoog{

 float x;
 float y;
 float w;
 float h;
 int eyeSize;
 int farbe;
 
 Zoog(float tempX,float tempY, float tempW, float tempH, int tempEyeSize, int tempFarbe){
   x= tempX;
   y= tempY;
   w= tempW;
   h= tempH;
   farbe = tempFarbe;
   eyeSize= tempEyeSize;

 }

 void drawZoog(float eyeColor){
   background(255);

   ellipseMode(CENTER);
   rectMode(CENTER);

   for (float i=y+5; i<y+h; i+=10){
     stroke(0);
     line(x-20,i,x+20,i);
   }

   stroke(0);
   fill(0);
   rect(x,y,w/6,h*2);
 
   fill(farbe);
   ellipse(x,y-h/2,w,h);

   fill(eyeColor);
   ellipse(x-w/3,y-h/2,eyeSize,eyeSize*2);
   ellipse(x+w/3,y-h/2,eyeSize,eyeSize*2);

   stroke(0);
   line (x-w/12,y+h,x-w/4,y+h+10);
   line (x+w/12,y+h,x+w/4,y+h+10);  
 }

 void jiggleZoog(float speed){

   x=x+random(-1,1)*speed;
   y =y+random(-1,1)*speed;

   x=constrain(x,0,width);
   y=constrain(y,0,height);


 }

 float augenfarbe(){
 float d = dist(x,y,mouseX,mouseY);          
 

   return d;

}

}

remove background(255) from the class and put it at the beginning of draw. you are not only drawing eyes you are drawing a background and overdraw the first Zoog
