在Windows窗体用户控件Embeding一的XNA Game [英] Embeding a XNA Game in a Windows Form User Control

问题描述

我写了一个简单的XNA 4.0游戏。我想制作一个Windows窗体用户控件，将渲染这个游戏，并提供必要的交互反馈（键盘和鼠标）回XNA。

我试过以下：

在XNA中：

• 将XNA的Game.GraphicsDevice

  发出一个事件发送一个对象与KeyboardState和MouseState要填写Windows窗体，在Update

在WinForms中：

• 捕获事件，使用Windows窗体中通常的键盘和鼠标事件获得的数据填充KeyboardState和MouseState。




• 在OnPaint上调用Game.RunOnFrame




• 从游戏中获取RenderTarget2D（作为纹理）。




• 另一个想法只是调用Game.Run（）（oa new

我发现了以下问题：

• 如果我调用Game.Run（），我无法隐藏游戏的窗口（显示为黑色，因为我重定向render ）




• Game.Run（）必须在不同的线程上调用，因为它启动一个新的事件循环（它调用应用程序方法），然后我




• 使用Color，Vector4甚至Rgba32锁定RenderTarget2D不会影响我们的用户控件

任何想法？

提前感谢。

解决方案

xna的网站上有一个关于嵌入xna在winform。它会带你通过所有的步骤。我为Xbox制作游戏，但我使用它为我们的引擎的级别编辑器。

I have a simple XNA 4.0 Game written. I want to make a Windows Form User Control that will render this game, and provide the necessary interaction feedback (keyboard and mouse) back to XNA.

I have tried the following:

In XNA:

• Redirect XNA's Game.GraphicsDevice to a RenderTarget2D.

• Emit an event sending an object with KeyboardState and MouseState to be filled in by Windows Forms, at the beginning of Update()

In WinForms:

• Capture the event, filling in KeyboardState and MouseState with data obtained by the usual keyboard and mouse events in Windows Forms.

• On the OnPaint, call Game.RunOnFrame()

• Get the RenderTarget2D from the game (as a texture).

• Lock the texture's data, and try to paint it pixel by pixel in my user control's Graphics.

• Another idea was just calling Game.Run() (o a new Thread) and emit an event in Game sending the RenderTarget2D.

I have found the following problems:

• If I call Game.Run() I have no way to hide the game's window (which appears black, because I'm redirecting the render)

• Game.Run() must be called on a different thread because it starts a new event loop (it calls Application methods), and then I'm painting in my user control from a different thread that it was created (bad, bad)

• Locking a RenderTarget2D with Color, Vector4, and even Rgba32 doesn't appear to work for me (it says 'wrong structure size')

Any ideas?

Thanks in advance.

There is a great code sample on xna's site about embedding xna in a winform. It takes you through all the steps. I make games for xbox, but I use this for the level editor we've made for our engine.
