Anyone able to make the lines go back when the reach the right edge and go forward when they reach the left again? Please and Thanks





int endX = 0;

void setup() {
size(200, 200);
frameRate (10);
endX = (0);

}
void draw() {
background (255);
stroke(0);
for (int x = 0; x < endX; x+=10) {
line(x, 0, x, height);
}

endX +=10;

if (endX > height) {
endX = 0;
}
}
