noStroke(); (Read 1335 times)
Joe Longstreet
noStroke();

Why doesn't processing allow you to set noStroke(); within an object?

How else can I achieve no stroke? strokeWeight(0); gives me one pixel.

Thanks,

Joe

What do you call "an object"? Can you give a simple example?

Code:

void setup() {

}
void draw() {

}

class Object {
    Object {
        noStroke(); //Throws an error
    }

}

just move it before you start to draw.
Object1 o1 = new Object1();

void setup() {
 size(200, 200);
}

void draw() {
 background(204);
 o1.update();
}

class Object1 {

 Object1 () {  

 }

 void update() {
noStroke();
fill(#ff0000);
ellipse(100,100,40,40);
 }
}

As Cedric said.
Your sample is problematic: you use Object as class name, but it already exists in Java (it is a fundamental class!). Beside, your constructor is lacking parentheses. The error doesn't come from the noStroke().

I was just trying to save time by writing that temporary document. Here is what I'm working on.

Code:
int i = 0;
int value = 0;

void setup() {
  size(640, 480);
  background(0);
  smooth();
  colorMode(RGB);
  color blue = color(0, 0, 153, 60);
  fill(blue);
}

void draw() {

}

void mouseClicked() {
  float tempRandX = random(mouseX-5, mouseX+5);
  float tempRandY = random(mouseY-5, mouseY+5);
  int(tempRandX);
  int(tempRandY);

  Circle newCirc = new Circle(tempRandX, tempRandY);
}

class Circle {
  float xpos;
  float ypos;
  
  noStroke();
  
  Circle(float tempRandX, float tempRandY) {
    xpos = tempRandX; 
    ypos = tempRandY;
    float randSize = random(30, 100);
    ellipse(xpos, ypos, randSize, randSize);
  }
}


noStroke throws an 'unexpected token' error

Also, I'm aware that you can insert noStroke(); into the constructor function. But what if I want to generate another class called triangle, and one called square. Both with different stroke properties.

you should read this tutorial about OOP. cause i believe you didnt totally understand how to use them. You are missing the functions where you draw, update, move etc. your object . You also have to call them in your main draw function...

Quote:
class Circle {
 float xpos;
 float ypos;
 
 //noStroke();
 //it's not a variable, don't put it here!
 
 // here is your constructor method:
 Circle(float tempRandX, float tempRandY) {
   xpos = tempRandX;
   ypos = tempRandY;
   float randSize = random(30, 100);
   // ellipse(xpos, ypos, randSize, randSize);
   // don't draw here!
 }
 
 better add this method to draw your object:
 void draw() {
   noStroke();
   ellipse(xpos, ypos, randSize, randSize);
 }
 
}


Then, call newCirc.draw(); when you want to display the circle.
