Question

programming with processing

Draw a circle in the top left corner of the screen. make your circle go around a square path continuously.the cycle should

-in a straight line go to the far-right side of the window

-in a straight line go to the bottom of the window

-in a straight line go to the far-left corner of the window

in a straight line go to the top left of the window

-keep repeating the above steps

This process should be repeated until program is terminated

drawing should not go out of the bounds of the window .

i have this so far can't get it to got to the left:

int x = 40, y = 40;

void setup()
{
size(600, 600);
}
void draw()
{
background (200);
ellipse (x, y, 80, 80);
if ((x<560))
{
x=x+xdir;
}
else if(y<560)
{y=y+ydir;
}
else if(x<560)
{
  

}
  
  
}

Answer 1

int x = 40, y = 40;


void setup()
{
        size(600, 600);
}

void draw()
{
        background (200);
        ellipse (x, y, 80, 80);
        
        // Move Up
        if (x == 40) {
                
                if(y == 40) {
                        x = x + xdir; // Start going right
                } else {
                        y = y - ydir; // Keep coming up.
                }
                
        }
        
        // Move down.
        else if (x == 560) {
                
                if(y == 560) {
                        x = x - xdir; // Start going right
                } else {
                        y = y + ydir; // Keep coming up.
                }
                
        }
        
        // Move Right.
        else if (y == 40) {
                
                if(x == 560) {
                        y = y + ydir; // Keep coming down.
                } else {
                        x = x + xdir; // Start going right
                }
                
        }
        
        // Move Right.
        else if (y == 560) {
                
                if(x == 40) {
                        y = y - ydir; // Keep coming Up.
                } else {
                        x = x - xdir; // Start going left
                }
                
        }
}
