hi, i'm an italian guy, this is my first post. I would know if there is a way to draw two ellipses one with stroke and the other without stroke. Some advice? Bye

how about using stroke() and noStroke()...
Code:void draw() {
ellipseMode(CENTER_DIAMETER);
background(128); // 50% grey background
stroke(255); // use white stroke
fill(255,255,0); // yellow fill
ellipse(25, 75, 40, 40);
noStroke(); // turn off stroke
fill(0,255,255); // cyan fill
ellipse(75, 25, 40, 40);
} |

thanks for cut & paste from the reference... ehehehe . So if i want to apply stroke to a single graphic object i have to do a method for that object that first set the stroke on/off and then redraw the object...

not really cut&paste, but hey...
stroke() or noStroke() settings will remain active until they're changed again. so if you draw 10000 objects with stroke you don't have to call stroke() for every single one of them... makes sense?

if i do this:
void setup(){
size(400,400);
stroke(55);
fill(150);
ellipseMode(CENTER_DIAMETER);
myEllipse g1ga = new myEllipse(200,200);
g1ga.stroked();
myEllipse g1ga2 = new myEllipse(300,300);
g1ga2.noStroked();
ellipse(350,350,15,15);
}
class myEllipse {
int mySize = 15;
float x,y;
int strokeColor = 55;
myEllipse(float _x, float _y){
x = _x;
y = _y;
}
void stroked(){
stroke(strokeColor);
ellipse(x,y,mySize,mySize);
}
void noStroked(){
noStroke();
ellipse(x,y,mySize,mySize);
}
}
the third ellipse has no stroke becuse the second called noStroke() that is valid for all the environment. i don't like this...

well, what can i say?! you don't like it, so work around it... you have the freedom, so use it! question is also why you're drawing the 3rd ellipse using the default syntax if you went through all the trouble of setting up a class structure. furthermore, i think if you work so much with stroked/non-stroked objects, it'd be wise to integrate a "stroke" property in the class and only have a single draw method, like:
Code:class Ellipse {
int size = 15;
float x,y;
int strokeColor;
boolean isStroked;
Ellipse(float _x, float _y){
x = _x;
y = _y;
isStroked=false;
}
void stroke(int c){
strokeColor=c;
isStroked=true;
}
void noStroke() {
isStroked=false;
}
void draw() {
if (isStroked) {
stroke(strokeColor);
} else {
noStroke();
}
ellipse(x,y,mySize,mySize);
}
} |
