• ChaCh PNG Alpha Channel

  I've imported a semi-transparent PNG to use for a sprite but the alpha channel isn't taken into account. It just renders as a fully opaque texture. How can I enable alpha channel support dagfari wrote: Use only one Spritebatch and see what happens. I tried that but it just lightened the blocks rather than letting the background shine through like my original problem. Here is source code for a project that has alpha channel png sprites and draws with full opacity and partial opacity on a background: http://www.bluerosegames.com/brg/XnaLesson12.zip Hopefully it might help you find your problem.

• maqk 2-D Modeling

  What do I need (as a program) to create 2-D sprites to use in a Pong type game. Other than a simple paint program I am also wondering about collision detection of the Pong type paddle and using 2 balls to detect collision. I have been learning by using the tutorial I found from some really smart guy...lol.. that created the air hockey game. I assume that he was using a 3-D modeler but I have no idea on where I would find such a thing and then bring it into my game as always thanks so much. I have found many of your responses helpfull and educational. For 2D graphics, 'Photoshop CS2' is the best but it's expensive. 'Paint Shop Pro' is a great and much less expensive alternative. Photoshop Elements is also a much cheaper ...Show All

• Balaji Srinivas Xbox Live Stats/Gamertag Webservice?

  Is there any means to access the Xbox Live webservice to read gamer related stats so as to create a custom stats program in .NET Is there a published API for this I've seen may websites doing mashups of gamer info and was interesting in trying it out if its possible. Ok thanks, that is what I thought. So there is no way to access the feed directly and it seems the developer program is now closed. I'm referring to accessing the Xbox Live stats from a PC or web based application. That, no. You can get the GamerTag, which is what I thought you meant - http://www.xbox.com/en-US/MyXbox/embedgamercard.htm You'd need to be a registered ...Show All

• Arun.kumar.sharma how to delete the threats?

  please tell me that how to delete my threads (formerly threats) That's true, but how many of us are writing the next Gears of War Unless you have some really clunky code or if you're networking, a lot(obviously there will be people who require the full power of the processor and GPU) of the people who use XNA will be fine with just a single thread. Correct me if I'm wrong here, I'd like to know more. Looks like I was wrong :/ I've done multi-threaded apps before, but I was just under the impression that most games that people would create with xna wouldn't involve multithreading. I guess i should do my research before making baseless claims next time :) Do you mean threads You shouldn't be multi-threading XNA applicatio ...Show All

• Luke R Any plans for Vista?

  Getting a new pc with Vista soon, is XNA Game Studio Express going to be compatible with Vista Any plans to make it compatible in the near future Thx. Here is how I got ti installed, but yes it is unsupported and the timeline will rely on other teams as the issue is not with XNA and Game Studio Express it is with the Visual Studio Products.

• jeffjarrett math.sin output error?

  Sorry to be asking such an obvious question, but I did a search and couldn't find this topic previously discussed. I'm having a problem where I seem to be getting the wrong value from the Math.Sin(x) function. The lack of search results on the subject would leave me to believe that there's not a bug in the software, so it must be something on my end. I'm trying to use sin to determine an object's new position on-screen, but as my formula stands the object appears in the wrong place. But, when I replace Sin(Value) with what my calculator tells me Sin(Value) should be, I get the right position. Here's a snippet of the code (In the final program, the values would be replaced by variables, but I'm using the numbers just to try and isolate my p ...Show All

• Ken Villines Where in content pipeline does volume textures fail?

  Currently volume textures aren't supported in the Content Pipeline. So if I have a mesh that references a volume texture it will fail compiling. So, is it just a matter of writing a custom importer for volume dds files or is it all the way through the pipeline Will ContentManager.Load<Texture3d>(...) work if I just write the importer Say it is so...it is Christmas after all :-) BlueG wrote: However, you could always pull a fast one on it and derive from Texture2DContent instead of TextureContent. The Texture2DContent class has a parameterless constructor. Then you would still be able to add new elements to the MipChainCollection created. That would be a nice work around but u ...Show All

• Edward1 The program compiles, but refuses to run

  So, every time I run it, it shows the error screen with the option to send them the message. If I check the contents, the things (The little P1 and P2s) are mostly gibberish, but one is microsoft.xna.framework.game. What's wrong Any help will be greatly appreciated.(Note: I'm doing the default windows game project, with no editing done on it.) From your example are you running it on your development machine (ie the one you compiled it on) or is it another machine, note that if it is on another machine you need to have the Same components installed that you have on your dev machine.... this includes the DX sdk, GSE VS C# and XNA... Okay, I fixed the problem. I removed the this.gamecomponets ...Show All

• geo2000 Creator's Club exclusive content?

  When will we start to see Creator's Club exclusive content I mean, it costs $129 (CDN) for this membership. And I don't think the only thing we payed for was the ability to deploy games on the Xbox 360. I'm guessing we'll have access to some member-only assets. And lots of other cool trinkets. If this is the case, when will see our money's worth Also, any news on XNA Racer Yes, I know there will be content in the future.

• rykk Game Tool programming in managed code.

  Since Managed DirectX is no longer supported, so what is my choice for managed 3d API beside Tao .net wrapper for OpenGL. this question is for the DirectX team or .Net team only. thanks as noNchaoTic says MDX 1.1 is still supported, however there will be no further enhancements. Your other choices are XNA and if you want to use OpenGL then Tao works too. I'm not on either team, but MDX 1.1 is supported. I would suggest this for game tools, it's what I use, hope this helps. I didn't like using XNA for tools, or at least what I was using. Oh and don't forget that WPF also does 3D ...Show All

• Henny Dream-Build-Play contest question

  In case you haven't heard yet here's the link. www.dreambuildplay.com/index.html I was just wondering if anyone knew exactly when it begins and if you need to have a 360 to be able to enter the contest. Cool. I didn't even think of that. No one outside of MS, and even then probably very few outside of whoever's running it, know exactly when as well as what the rules are. Keeping hitting the site every day, as I'm doing, and you'll find out soon enough. It sounds like an interesting thing, I'll probably enter my Banshee game... By the way, I don't know if anyone noticed, but the dashes and dots towards the bottom are Morse code for "your world, your game" ...Show All

• BLytt Out of video memory when I have plenty (128Mb)

  I've had several computers fail to create the DirectX device in full screen mode because of an "out of video memory" error. In two cases, the cards have 128Mb, and I'm sure it's not using even close to that much video memory (front buffer + 2 back buffers = 3*1440*900*4 = 14.8Mb (not even close to 128Mb). On one computer, I was able to solve the problem by lowering the DirectX quality settings from the control panel. On the other computer, that didn't solve the problem. I'm sure my program isn't requesting high quality settings (MultiSample = none, MultiSampleQuality = 0). Does anyone have any idea of why this would happen, or what I can do to fix the problem Thank you, Jeremy JeremyAtGosu ...Show All

• Old Mortality Highly Optimized 2D Drawing

  With the trends in hardware today, would it be worth the effort to render groups of sprites to offscreen surfaces For instance, we have an gui window composed of 9 sprites (All stored in 1 image, and will be rendered in a batch). 5 Of these sprites will every need scaled or tiled to draw the window every frame. Assuming that during the gui windows lifetime it's size and appearance will remain relatively constant, we can render it to an offscreen surface. This would allow us to minimize the scaling and vertex buffer operations to a single blit in future redrawings of the window. Or is it best to constantly push new quads to the GPU for processing like the Spritebatch object currently does The constant pushing of quads would only requir ...Show All

• JaguarRDA283361 Designer Property collections

  I want to create a menu game component like the one in Mitch Walker's video (http://blogs.msdn.com/xna/archive/2006/08/31/734204.aspx) on the XNA team blog. I got a hardcoded menu working but how do I make it that the developer can add menu items from the property window in Visual Studio like in the video Hi there, Andre, I've been trying your code in storing items in the Property Grid collection, but are running into this problem. The code works fine in the designer once (drop the component and going into the collection editor). The code works ok in runtime, but when the program returns I get this error when viewing the program's design view: One or more errors encountered while loading the designer. The errors are listed be ...Show All

• cedubose Will XNA Game Studio Express support multiplayer? (on the 360)

  Please, please tell me that XNA Game Studio Express will support multiplayer... Singleplayer games are fun, but multiplayer games are 10x as fun. You are right. I haven’t thought about this kind of multiplayer even if I had build such multiplayer games in the past. You should still be able to do multiplayer games I would imagine (split screen or hot seat), just not networked. Thanks for the clarification. For windows you could use the standard System.Net namespace of .NET (outside of XNA) to support full multiplayer support. For the XBox 360 you have to wait for the next release of the XNA Framework. Jim is right. We will support m ...Show All
