• blah569 Model class vb woes

  Is there anyway to specify creation parameters for vertex buffers that are created by ContentManager.Load<Model>, i.e.: I want to be able to read back from those buffers. I suspect (from 20 mins of googling and reading bits and bobs) that there is not. Just wanted to double check. If not, does anyone know if there is a good reason why not Cheers, and thanks, Ste Is this likely to change in the future Currently, the default Model class always uses readonly vertex and index buffers. The only way around that is to make your own model type, or store the vertex data somewhere else rather than trying to read it back from the D3D buffers. I don't know what you ...Show All

• Lee Whitney Question regarding making landscape in 2D

  My question is rather simple. I have a texture and a landscape map to apply it to. It is possible to make a rectangular sprite in XNA, but is it possible to cut a part from it Here's an example for better understanding of what I'm aiming for: http://img335.imageshack.us/img335/9972/examplent7.jpg The only way I can think of is to make a different texture for every sprite, changing its shape every time. But that really it not the easiest and smartest way... As it requires a Rectangle, you still wouldn't be able to produce a non-rectangular shape as you would like. Alright... now I finally understand what exactly you are doing and why. You're creating a landscape ...Show All

• sticky How in XNA Game Studio Express correctly to include a full-screen mode?

  How in XNA Game Studio Express correctly to include a full-screen mode I write a code: graphics.PreferredBackBufferWidth = 1024; graphics.PreferredBackBufferHeight = 768; graphics.PreferMultiSampling = false ; graphics.ToggleFullScreen(); Then I draw on the screen 2D the sprite and I move it on the screen.

• Philipp Lamp Beta 2 sneak peak

  The XNA guys did a demo of the beta 2 bits at Code Camp Seattle today. See my notes here http://www.thezbuffer.com/articles/424.aspx Please honour my request not to ask follow up questions here until the beta releases - I wrote everything that was public so its unlikely that anyone will be able to answer any of your questions until then. See also pictures of the demo code: http://www.thezbuffer.com/articles/426.aspx http://www.thezbuffer.com/articles/427.aspx I just added links to pictures of the demo (mostly code) to my 1st post in this thread.

• JoshKorn ContentLoadException

  Hello, loving XNA so far. But when I try to use this: Model model; ContentManager contentManager = new ContentManager(GameServices); model = contentManager.Load<Model>("boing.swm"); Code I get the ContentLoadException which states it cannot find the file speficied in the file, which is located in the project. So I am trying to figure out what is causing this exception. Any help would be much appreciated. Check dates Dude I see what you mean. I don't think that would fix the problem though. I'm almost tempted to submit a bug report and see what they say. I'm wondering what is causing this exception though. ...Show All

• Walter Zorn Drawing a simple image

  Does anyone know how to draw an image at the location of the mouse Is this considered a sprite I have little knowledge about how this image should be drawn but I know how to make sure that it is in the correct position of the mouse. Any help appreciated. Thanks. What would be some ways of doing this I haven't an idea of how to get a sprite to display or even what a textured quad is. You could do it with a sprite, which may be more appropriate, you can also do it with a textured quad. Actually I just found what I was looking for.

• pratyusha kothi XNA doomed?

  XNA may be the greatest thing since sliced bread, but I don't see it getting a lot of support until you make a simple web page that explains what features the XNA framework supports and why I would want to use it. I'm not going to download the thing just to figure out what it is. I also find this thread to be a little silly. I compare your statement to someone coming along and looking at a can of Coca-Cola and saying, "This product will certainly fail, it doesn't give a good idea on the can of what it tastes like." If you really are the type of person who needs to know what something tastes like before you try it, then you should sit back and let the early adopters enjoy the flavor of a new ex ...Show All

• Aamer DX10 and XNA

  Hi. Are there any future plans for the XNA framework be upgraded to support DX10 features and retain compatibility with Xbox I read how radical the new API will be and it will not be backwardly compatible with DX9. Although Vista can still run DX9 games, it will be slower as it will be via a software layer. since DX10 will also need new graphics hardware too, that suggest to me that XNA may not ever access DX10 functionality. Unless a new Xbox is on the horizon. The focus on the XNA framework right now is on cross-platform compatability. Some time in the future, there will be support for Direct3D 10, but we haven't announced anything yet. The only software layer that Direct3D 9 on Vista uses i ...Show All
