刚刚开始学习用processing， 现在需要做一个转盘出来～～可以用空格键控制开始和暂停的～～但是现在用了各种方法只能暂停不能在开始～～谁能帮我改一下～～～跪谢啊！！
这是现在写的～～
boolean runAnimation = true;
void setup() ｛size(700,700);
frameRate(60);
background(250);}
void draw(){
if (mousePressed) {
stop();
}
// runAnimation = !runAnimation;
float i = millis()/5.00;
fill(153,204,255);
arc(350,350,600,600,radians(i),radians(60+i));
fill(255,153,102);
arc(350,350,600,600,radians(60+i),radians(120+i));
fill(255,153,255);
arc(350,350,600,600,radians(120+i),radians(180+i));
fill(153,204,153);
arc(350,350,600,600,radians(180+i),radians(240+i));
fill(204,153,102);
arc(350,350,600,600,radians(240+i),radians(300+i));
fill(255,255,102);
arc(350,350,600,600,radians(300+i),radians(360+i));
noStroke();
fill(255,255,255);
ellipse(350,350,50,50);
fill(255,255,255);
rect(347,350,6,-70);
ill(255,255,255);
triangle(359,281,350,263,341,281);}
