Monogame

Question

我在尝试在 monogame 中加载 .png 文件时遇到了一个不常见的问题。

尽管文件位于相同的确切位置，但我收到一条异常消息：

Unhandled Exception: Microsoft.Xna.Framework.Content.ContentLoadException: The content file was not found. ---> System.IO.FileNotFoundException: Could not find file 'C:\Users\...\RiderProjects\PointAndClickEngine\PointAndClickEngine\Content\EnabledButton

更奇怪的是TestBackground.png不知为何加载成功了。我完全不知道是什么原因造成的。我试过移动文件以查看是否可以正常工作，但无济于事。上网查了一下，似乎没有其他人有这个问题。 Game.cs:

感谢任何帮助！

Answer 1

您遇到的问题是它正在尝试加载一个不存在的文件。

异常表明它正在寻找文件 "EnabledButton.xnb"，但您显示文件的文件夹名为 "ButtonEnabled.xnb"。所以名字不一样。

我想 "DisabledButton.xnb" 也会出现同样的情况。

所以这些代码行：

 elements = new Element[]
        {
            new Door(doorTextures, Vector2.Zero, 10),
            new Door(doorTextures, Vector2.Zero, 10),
            new DoorButton(Content.Load<Texture2D>("EnabledButton"), Content.Load<Texture2D>("DisabledButton"),
                elements[0] as Door, new Rectangle(0, (int) (height * 1.25), 158, 128)),
            new DoorButton(Content.Load<Texture2D>("EnabledButton"), Content.Load<Texture2D>("DisabledButton"),
                elements[1] as Door, new Rectangle((int) (width / 1.1), (int) (height * 1.25), 158, 128)),
        };

应该这样读：

 elements = new Element[]
        {
            new Door(doorTextures, Vector2.Zero, 10),
            new Door(doorTextures, Vector2.Zero, 10),
            new DoorButton(Content.Load<Texture2D>("ButtonEnabled"), Content.Load<Texture2D>("ButtonDisabled"),
                elements[0] as Door, new Rectangle(0, (int) (height * 1.25), 158, 128)),
            new DoorButton(Content.Load<Texture2D>("ButtonEnabled"), Content.Load<Texture2D>("ButtonDisabled"),
                elements[1] as Door, new Rectangle((int) (width / 1.1), (int) (height * 1.25), 158, 128)),
        };

请注意我是如何将 EnabledButton 更改为 ButtonEnabled 和将 DisabledButton 更改为 ButtonDisabled.
