如何在XNA在运行时加载纹理？ [英] How do I load a texture in XNA at runtime?

问题描述

我正在使用XNA的框架，这样做的3D渲染的应用程序。我现在想从文件加载纹理。我发现两种方法至今：

I'm working on an application that uses the XNA framework to do it's 3D rendering. I now want to load a texture from file. I've found two methods so far:

1. Texture2D.FromStream（GraphicsDevice的，流）这种方法的问题是，它只会加载GIF，PNG和JPG，我还需要TGA图像的支持。


2. 创建一个 ContentManager 对象。这种方法的问题是，它似乎像所有的纹理需要静态添加到项目中，从文档：以前一个ContentManager可以加载的资产，你需要将资产添加到您的游戏项目。有问题的程序是一个关卡编辑器和需要哪些纹理事先是不知道。

1. Texture2D.FromStream(GraphicsDevice, Stream) The problem with this approach is that it only loads gif, png and jpg and I also need support for tga images.
2. Create a ContentManager object. The problem with this approach is that it seems like all the textures need to be statically added to the project, from the documentation: "Before a ContentManager can load an asset, you need to add the asset to your game project". The program in question is a level editor and which textures are needed isn't known in advance.

有没有其他简单的方法来加载纹理，我在考虑使用一些其它的类加载图像（虽然我不知道我这，不是很熟悉C＃），然后也许使用 Texture2D.SetData 方法？

Is there any other easy way to load the texture, I'm thinking about using some other class to load the image (although I don't know which, I'm not very familiar with C#) and then perhaps use the Texture2D.SetData method?

有没有其他简单的方法来实现我想要达到什么目的？

Is there any other easy way to achieve what I'm trying to achieve?

推荐答案

有一些方法来达到你想要什么：

There are a few ways to achieve what you want:

1. 你可以的编辑器中调用从的内容管道，动态创建内容的项目。如何做到这一点在的WinForms系列2样品。这大概是最好的方式，因为它允许您使用内容管道保持。

1. You could invoke the content pipeline from within your editor, dynamically creating your content project. How to do this is described in the WinForms Series 2 Sample. This is probably the "best" way, because it allows you to keep using the content pipeline.

您可以，就像你说的，解码TGA文件的自己并使用的SetData 。有很多结果在谷歌C＃TGA读者。 这是第一个。

You could, as you say, decode the TGA file yourself and use SetData. There are lots of results for C# TGA readers on Google. This is the first one.
