好吧,我试图让我的游戏窗口能够统一调整 。我到处检查过,但我似乎无法找到任何相关信息。
有什么想法吗?
由于字符限制,我无法发布代码。如果有人能帮助我,看看我做错了什么,我将不胜感激:)
同样有用的是如何在发生这种情况时调整后备缓冲区的大小,因为我不认为只有一半的精灵可以玩游戏:)
void Window_ClientSizeChanged( object sender, EventArgs e )
{
int new_width = graphics.GraphicsDevice.Viewport.Width;
int new_height = graphics.GraphicsDevice.Viewport.Height;
if (new_width != Variables.SCREEN_WIDTH)
{
Variables.SCREEN_HEIGHT = (int)(new_width * ascept_ratio);
Variables.SCREEN_WIDTH = new_width;
}
if (new_height != Variables.SCREEN_HEIGHT)
{
Variables.SCREEN_WIDTH = (int)(new_height / ascept_ratio);
Variables.SCREEN_HEIGHT = new_height;
}
UpdateParameters();
}
...
public void UpdateParameters()
{
graphics.PreferredBackBufferWidth = Variables.SCREEN_WIDTH;
graphics.PreferredBackBufferHeight = Variables.SCREEN_HEIGHT;
graphics.ApplyChanges();
}
谢谢,
亲切的问候,Darestium

要保持宽高比吗?
您可以像任何WinForms项目一样执行此操作:
当表单加载时,存储方面无线电:(float)Width/(float)Height
。在XNA中,这可能位于游戏的LoadContent
中(因为窗口将在那时创建)。
然后,处理表单的sizechanged
事件。您需要跟踪用户是否正在更改高度,宽度或两者。如果是高度,则设置Width = Height / AspectRatio
,如果宽度更改设置为Height = Width * AspectRatio
。
如果两者都改变了,那么决定宽度或高度,(我的意思是在设计中选择一个,而不是每个调整大小)并按上述方式进行。
一旦你完成了这项工作,你可能不得不做一些XNA特定的事情,例如调整后备缓冲区的大小等等。但这不是特定于这个问题所以我会把它留下来(如果需要的话还会问另一个问题)定)。
修改。以下是最小的工作样本:
它保持纵横比,并通过将渲染目标绘制到窗口的原始大小来调整图形大小,然后绘制缩放以适合新窗口。如果您不希望这样,请删除已覆盖的BeginDraw
和EndDraw
方法。

我的猜测是这段代码不起作用,因为它会一直调用自己,因为ClientSizeChanged事件会触发ClientSizeChanged事件。
也许您需要检查并查看窗口是否已经具有正确的宽高比,而不是进一步更改窗口。
