float t = 0.0;
float a=0.0;
void setup()
{
 size(350, 350);
 stroke(51);
 background (255);
 framerate(35);
}

void draw()
{
   t = t - 2.5;
    if (t<0){
     t=height;
     if (a>350){
   a=0;
 }
 }
 line(0, t, width, t);  
 line (t,0,0,width);
 line (125,0,t,width);
 line (-350,width,t,0);
 line (250,width,0,t);
 line (width,300,t,0);
 
}

Hi, I tried the basic looping but it doesnt seem to be looping...

i was wondering if you can tell me the problem here so i can have this animation continuously on the move (looping)...

thanks

It's looping. But you can't see this, cause you draw the lines over the old lines. So at the end of the loop you have to clear the screen (background(255)).

You just need to add background()at the start or end of your draw()block, as shown below. This means your display will be rereshed every time the code runs, and you can therefore see it looping...

float t = 0.0;
float a=0.0;
void setup()  
{
 size(350, 350);
 stroke(51);
 background (255);
 framerate(35);
}

void draw()

{
background(255);
   t = t - 2.5;
    if (t<0){
t=height;  
if (a>350){
   a=0;
 }
 }
 line(0, t, width, t);  
 line (t,0,0,width);
 line (125,0,t,width);
 line (-350,width,t,0);
 line (250,width,0,t);
 line (width,300,t,0);
 
}
