在没有内容管道的XNA中加载模型

Question

Now, I love XNA. It's an awesome framework, except for one thing.

The content pipeline.

It's a huge no-no for any game that encourages modding and user-created content, especially for a game like mine which practically depends on it.

How would one go about loading a skinned+animated .x file into a Model class?

I assume that you have to load the file normally, parse it, and build up a Model out of ModelMeshes, but I don't have any clue how I would go about creating ModelMeshes from scratch.

I don't even need you to tell me how to do it, pointing to some good articles or tutorials would be perfect.

Thanks in advance!

EDIT: I have searched around for this, a lot, but everything I see just tells me to use the content pipeline.

Answer 1

If you're looking for loading .x files only, I don't have any answers except to refer you to the .X file format reference . But since you mention that user-created content is very important - I will point out that COLLADA is a great option. Open Model Implementation for XNA is a good library that can get you started loading COLLADA files, but it is still upto you to render them - or use the OMI renderer.

Hope this helps some!

Answer 2

You can compile the models at runtime if you so desire. This will lead to long loading times of you have a lot of files so I suggest saving the results from the compilation and only recompiling if necessary (new file or changes since last compilation).

There is a sample that does thin somewhere on the AppHub but I suggest you check out this project it should be very easy to modify to do exactly what you need.

Also check out the gamedev stackexchange if you have more gamedev related questions.

Edit: Also huge thumbs up on supporting the modding community that inevitably pops up around any good game which I'm sure your will be.
