較小的三角形

修改 drawTriangle() 的c 路徑

c.moveTo(140, 10);
c.lineTo(160, 10);
c.lineTo(150, 25);
c.lineTo(140, 10);

c.moveTo(140, 10);

c.lineTo(160, 10);

c.lineTo(150, 25);

c.lineTo(140, 10);

移除選中

程式碼

let segmentNumber = theWheel.getIndicatedSegmentNumber();
theWheel.deleteSegment(segmentNumber);
theWheel.draw();

let segmentNumber = theWheel.getIndicatedSegmentNumber();

theWheel.deleteSegment(segmentNumber);

theWheel.draw();

.getIndicatedSegmentNumber() 取得位置
.deleteSegment() 刪除
.draw() 重新繪製
