Hey guys !

I need some help. I  want to make five objects without using a array and I want to assign random values to the class, the random values range is same for all the class objects.

Where can I write the code so that the objects take different values ?

Please any help is appreciated.

Thanks

Hi everyone ! I have a question about making classes. Why do you make class and, how can you write procedure within a class  to generates and return a single random object ?

Hey Guys I have a question. My professor gave us this example in class


int total;
float average;
total = 12+25+36+15;
average = total / 4;
print ("The average is ");
print (average);

and the average printed out to 22. However, why did he do float, even is you do int average you get the same answer.
Any help will be greatly appreciated.

Also when do you use float ? And what is float ?

I am trying to draw random fishes in this aquarium but I am only seeing one fish why ? Please if one can help me out !
Here is the code :

void setup () {
  size (900,600);
  background (0) ;
  // aquarium body
  stroke (0);
  fill (255,102); // using alpha transparency
  rectMode (CENTER);
  rect (450,320,800,500);
  //
  for (int i=1; i<=30; i++) ; {
    drawFish (int (random (450,370)), int (random (320,400)), int (random (20,65)), int (random (30,60)), int (random (0,2)), int (random (0,255)), int (random (0,255)), int (random (0,255)));
    }
}


void drawFish (int x, int y, int w, int h, int d, int c1, int c2, int c3) {
 
 //body
 fill (c1,c2,c3) ;
 ellipse (x,y,w,h);
 
 //direction - odd left, even right
 if (d%2==0) {
  
 // tail
 fill (c1,c2,c3);
 triangle (x-(w/2),y,x-w,y+(h/2),x-w,y-(h/2));
 //outer eye
 fill (255);
 ellipse(x+(w/4),y-(h/4),8,8);
 //inner eye
 fill (0);
 ellipse (x+(w/4),y-(h/4),4,4) ; }
 
 else {
  
 //tail oppposite side
  fill (c1,c2,c3);
 triangle (x+(w/2),y,x+w,y-(h/2),x+w,y+(h/2));
 //outer eye opposite side
 fill (255);
 ellipse (x-(w/4),y-(h/4),8,8);
 //inner eye
 fill (0);
 ellipse (x-(w/4), y-(h/4),4,4);
 
 }
 
}
 

Can anyone help me to change direction of this object ? What functions do I need to do to change direction of an object, the object should not move but when you change the values it changes direction left to right. Should I be using the "if" function ?

Any help would be appreciated.

void setup () {
 
  size (250,250);
 
 
}
 

void draw (){
 fill (144,144,144) ;
 ellipse (75,75,55,35);
 triangle (47.5,75,27.5,55,27.5,95);
 fill (255);
 ellipse(86,65,8,8);
 fill (0);
 ellipse (86,65,4,4) ;

}

I am new at processing. I was wondering if anyone here can teach me how to do loops and what is the difference between for loop and while loop ?. I do not get them, any help will be appreciated.

Thanks.
