background(#FFFFA2); //色彩的色碼#RRGGBB

rect(100,100,400,200);

//在100,100的地方,寬度400,長度200的長方形

fill(#FFFFA2);//填充色

ellipse(300,200,100,100);

size(400, 400);

fill(#FFDC0F);

noStroke();//不會有邊緣的筆觸

//ellipse(50,50,100,100);//本來畫圖

arc(50, 50, 100, 100, -1, PI*2-1,PIE);//改畫弧度

//X座標,Y,寬,高,開始,結束,蘋果派的畫法

加上for就可以畫出很多小精靈
