我正在使用 XNA 开发 C# 项目。如果有一种方法可以在游戏运行时实时绘制某些变量的值，将会非常有用。 （只是为了调试，我不想在最终项目中使用图表。）
这似乎以前可能已经做过，但我找不到除此之外的任何内容：

我愿意写我自己的系统或使用别人的系统。如果有一个现有的已发布项目，我想找到它，这样我就不必重新发明轮子。如果不是，处理这个问题的最佳方法是什么？
谢谢！
I'm working on a project in C# using XNA. It would be useful to have a way to graph the value of certain variables in real time as the game is running. (Just for debugging, I don't want the graphs in the final project.)
This seems like something that has probably been done before, but I can't find anything other than this:

I'm willing to write my own system or use someone else's. If there is an existing released project, I'd like to find it so I don't have to reinvent the wheel. If not, what;s the best way to handle this?
Thanks!

您可能可以使用 XNA 编写一个非常简单的系统。
您应该有一些非常基本的东西来绘制线条：
在每一帧上运行这个系统来收集变量的值。跟踪以前的值。
在先前值和当前值之间画一条线。
如果采样频率足够高，您可以获得像这样的看起来相当不错的图表。
You could probably write a pretty easy system using XNA.
You should have something very basic for plotting lines:
Run this system on every frame to collect the variable's value. Keep track of previous value.
Draw a line between previous value to current value.
If the sampling frequency is high enough, you can get a pretty decent looking graph like this.
您可以将要检查的值写入 csv 文件，然后使用 Excel 绘制图表。 这是关于用 C# 编写 csv 文件编写器/解析器的教程。
XNA 不支持直接在屏幕上绘制单行/像素（需要通过 SpriteBatch）。我唯一能想到的就是使用texture2D并在其上绘制图形的像素。不过，你必须将纹理保持在镜头前，并使用一些我实际上不太了解的奇怪矩阵魔法。 ：P
You could write the values you want to check in a csv file, then draw a graph with excel. Here's a tutorial on writing a csv file writer/parser in C#.
The XNA hasn't support for drawing single line/pixels to screen directly (need to pass through a SpriteBatch). The only thing else I can imagine of is using a texture2D and draw your graph's pixels on it. You'll have to keep the texture in front of the camera though, with some strange matrix magics of which I don't actually know much. :P
Xen图形API具有此功能。它似乎适用于某些内置变量，例如 FPS，但它都是开源的，因此我怀疑添加您自己的图表会很容易： http://xen.codeplex.com/

我刚刚记得Farseer物理也有代码来做到这一点http://farseerphysicals.codeplex.com/。它可能比 Xen 图更容易撕掉。
The Xen graphics API has this feature. It appears to be for some built in variables, such as FPS, but it's all open source so I suspect it will be easy to add graphs of your own: http://xen.codeplex.com/
EDIT
I just remembered that Farseer physics also has code to do this http://farseerphysics.codeplex.com/. It's probably easier to rip out than the Xen graphs.
