Help with this clock
May 9th, 2010, 2:01pm  
I made a simple clock program. Left column displays hours, the middle column, the seconds and the right one, the minutes. I've a problem whith this program. I can not make the ellipses of the hours, minutes, seconds, and the lines disappear every second, minute or hour that passes.

Can anyone help me?



Code:
float ysegundos,yhoras,yminutos;
void setup () {
size (350,700);
background (0);
for (int i=0;i<=24;i++) {
 fill (#00039B);
 rect (65,yhoras,8,5);
 yhoras=yhoras+30;
 }
for (int i=0;i<=60;i++) {
 fill (#00039B);
 rect (168,ysegundos,9,3);
 ysegundos=ysegundos+11.5;
 }
for (int i=0;i<=60;i++) {
 fill (#00039B);
 rect (270,yminutos,8,5);
 yminutos=yminutos+11.5;
 }
}
void draw (){
   fill (255);
   ellipse (162,second()*11.72,7,12);
   ellipse (184,second()*11.72,7,12);
   stroke(255);
   line (1,350,59,hour()*26.17);
   line (80,hour()*26.17,161,second()*11.72);
   line(184,second()*11.72,263,minute()*11.8);
   ellipse (263,minute()*11.8,7,12);
   ellipse (286,minute()*11.8,7,12);
   line (350,350,286,minute()*11.8);         
   ellipse (80,hour()*26.17,7,12);
   ellipse (59,hour()*26.17,7,12);
}


Thank you in advance.

add   background(0); right after draw() to erase your screen with every frame. you have to move your grid  draw though.

Thanks for you reply, but it doesn't work, because blue rectangles are deleted. I tried to put setup() iterations into draw(), but it doesn't work. I'm getting mad.

Thank you.

Code:
float ysegundos,yhoras,yminutos;
void setup () {
size (350,700);

}
void draw (){
 background (0);
 
 for (int i=0;i<=24;i++) {
 fill (#00039B);
 rect (65,yhoras,8,5);
 yhoras=yhoras+30;
 }
for (int i=0;i<=60;i++) {
 fill (#00039B);
 rect (168,ysegundos,9,3);
 ysegundos=ysegundos+11.5;
 }
for (int i=0;i<=60;i++) {
 fill (#00039B);
 rect (270,yminutos,8,5);
 yminutos=yminutos+11.5;
 }

   fill (255);
   ellipse (162,second()*11.72,7,12);
   ellipse (184,second()*11.72,7,12);
   stroke(255);
   line (1,350,59,hour()*26.17);
   line (80,hour()*26.17,161,second()*11.72);
   line(184,second()*11.72,263,minute()*11.8);
   ellipse (263,minute()*11.8,7,12);
   ellipse (286,minute()*11.8,7,12);
   line (350,350,286,minute()*11.8);	   
   ellipse (80,hour()*26.17,7,12);
   ellipse (59,hour()*26.17,7,12);
}

your variables get bigger and bigger now as you dont reset them. one way would be to set them to 0 at the end of draw. but you actually dont need them at all.

just do it like that

 for(int i=0;i<=24;i++){
 rect (65,i*30,8,5);
 }

You never reset the values of yhoras, ysegundos, or yminutos! Or, as Cedric suggested (he's quick!), use the looping variables themselves to determine positions.

OMG What stupid mistake.

Thank you so much. I really appreciate it.
