C64加载屏幕想法

本文关键字:屏幕 加载 C64 | 更新日期: 2023-09-27 18:29:38

我制作了一个加载屏幕(启动屏幕),就像旧的C64一样。

我使用了一系列图片框,只需使用计时器和案例说明更改彩色图像。

switch (a)
{
    case 1: 
        pictureBox1.Image = Properties.Resources.image1;
        pictureBox8.Image = Properties.Resources.image1;
        pictureBox10.Image = Properties.Resources.image1;
        pictureBox2.Image = Properties.Resources.image1;
        pictureBox11.Image = Properties.Resources.image1;
        pictureBox9.Image = Properties.Resources.image1;
        break;
    case 2:
        pictureBox1.Image = Properties.Resources.image2;
        pictureBox8.Image = Properties.Resources.image2;
        pictureBox10.Image = Properties.Resources.image2;
        break;
    case 3:
        pictureBox1.Image = Properties.Resources.image3;
        pictureBox8.Image = Properties.Resources.image3;
        pictureBox10.Image = Properties.Resources.image3;
        break;
    case 4:
        pictureBox1.Image = Properties.Resources.image4;
        pictureBox8.Image = Properties.Resources.image4;
        break;
    case 5:
        pictureBox1.Image = Properties.Resources.image5;
        pictureBox8.Image = Properties.Resources.image5;
        break;
    case 6:
        pictureBox1.Image = Properties.Resources.image6;
        pictureBox8.Image = Properties.Resources.image6;
        break;
    case 7:
        pictureBox1.Image = Properties.Resources.image7;
        pictureBox8.Image = Properties.Resources.image7;
        break;
    case 8:
        pictureBox1.Image = Properties.Resources.image8;
        pictureBox8.Image = Properties.Resources.image8;
        break;
}

它看起来有点恶心,我该如何改进我的代码?

C64加载屏幕想法

您可以看看Iterator的设计模式。您可以创建一个表示单个阶段的类,该类将具有每个图片框的属性,并将这些属性的值设置为资源文件中的相关项目。

然后为每个加载阶段创建该对象的实例,将它们放在集合中,并编写迭代器来循环该集合。

有两件事我需要改进:

  • 将图像存储在阵列中,这样就不必每次都重复case X/imageX

  • 先处理常见的事情,然后集中精力处理特殊情况。

您可以将表单中的数组声明为"伪"常量,因为它不会更改:

private readonly static Image[] myImages = new[] {
    Properties.Resources.image1,
    Properties.Resources.image2,
    Properties.Resources.image3,
    Properties.Resources.image4,
    Properties.Resources.image5,
    Properties.Resources.image6,
    Properties.Resources.image7,
    Properties.Resources.image8
}

然后在你的定时器中使用以下代码:

Image image = myImages[a-1];
pictureBox1.Image = image;
pictureBox8.Image = image;
// special cases
if (a == 1)
{
    pictureBox2.Image = image;
    pictureBox11.Image = image;
    pictureBox9.Image = image;
}
if (a >= 1 && a <= 3)
{
    pictureBox10.Image = image;
}
