變量與時間控件:

 private Color emitterColor = Color.FromArgb(255, 0, 0); // 發射器顏色
 private Color ringColor = Color.FromArgb(0, 0, 255); // 圓環顏色
 private Color bubbleColor = Color.FromArgb(255, 0, 255); // 氣泡顏色
 private int batteryPercentage = 0; // 電量百分比
 // 在類的成員變量中定義一個用於保存旋轉角度的變量
 private double rotationAngle = 0;
private void timer1_Tick(object sender, EventArgs e)
{          
    // 電量百分比隨時間變化
    rotationAngle = (rotationAngle   5) % 360; // 每次更新角度增加5度，控制旋轉速度
    this.batteryPercentage = (this.batteryPercentage   1) % 101;
    this.Invalidate(); // 重新繪制窗體
}
