其实我是根据gh代码改的
ArrayList L=new ArrayList ();
//PeasyCam cam;
int total=400;
float x[]=new float[total];
OnCircle c1;
OnCircle c2;
PFont font;
public void setup() {
//
// cam = new PeasyCam(this, 200);
// cam.setMinimumDistance(50);
//cam.setMaximumDistance(5000);
size(600,400);
noLoop();
ellipseMode(CENTER);
background(255);
font= createFont("FFScala", 10);
textFont(font);
for(int i=0;i3){x[i]= random(15,30);}
else {x[i]= random(8,14);}
}
c1=new OnCircle(new On3dPoint(width/2,height/2,0), x[0]);
c2=new OnCircle(new On3dPoint(x[1]+width/2 + x[0],height/2,0), x[1]);
L.add(c1);L.add(c2);
line(c1.Center.x,c1.Center.y,c2.Center.x,c2.Center.y);
///*
for(int i=2;i=0;j-=1){

c1 =(OnCircle)L.get(j);
sign = false;
break;
}
}
count += 1;
} while(count<20 && sign == false);
if (sign){
L.add(c3);
line(c3.Center.x,c3.Center.y,c2.Center.x,c2.Center.y);
