• Landon Parks Issue with XNA Tutorial and scrolling backgrounds

  Greetings, I followed the second XNA tutorial, and got to creating a scrolling background for the space ship program. My problem is that as soon as I added the code from the tutorial for the scrolling background, the space ship became somewhat transparent, meaning that I am not seeing it like a solid rather a sum total of spheres and other geometries. For example, I can now see the 4 spheres on the surface of the ship in their entirety, and also the scrolling background behind it. Can someone help me out here Thanks! Ah. That's very different. Did you make sure to follow the "Hint: Make sure you use a call to SpriteBatch . Draw that allows you to specify a layerDepth parameter, and set that ...Show All

• Detisch the error

  I would like my game to come up to the opening scene, and when i press the spacebar it goes away and my game starts. I have tried something like this in my program: void _startGame; { using (Blank game = new Blank()) { game.Run(); } } But when i press spacebar it gives me an error. Thanks, for the help! It's ok,  i found something that if i make the Vector2 a negative and tell the splash to move up from its starting position to a point on the screen where it's not visible it wont show anymore Thx for all your help!

• JuergenMayer Is *ANYTHING* the same as the last Beta?!?!?!

  WHAT THE *&#@$ is wrong with you! ! ! ! ! Sorry guys, this totally pisses me off here... I had a solid game engine going with the last beta and now NOTHING works. Sorry, you guys suck for this one... Don't give me the whole beta schpeel either, cuz you DON'T change that much between betas, you have that nailed-down beforehand...

• StevenR2 fx problem ?

  Hi all, I has few fx effect problem. Hope somebody help. Q1. How to move texture uv with fx Q2. How to create smooth effect Please give to some suggestion about create smooth effect with fx. Best Regards, Q1. How to move texture uv with fx If you're using a vertex or pixel shader then the UV texture coordinate is just a numerical input - you can manipulate it (move/scale/distort..) as you see fit. The only potential complication is you can run into dependent reads. Q2. How to create smooth effect Please give to some suggestion about create smooth effect with fx. You'll need to provide a lot more information about what you want. A smooth effect could be various forms of shading (D3D will g ...Show All

• Vadim G So how does this (non)commercial business work?

  Can anyone please enlighten me on how this all will work. How I see it, there are two points for having XNA. 1. To let gamers make Xbox 360 non-commercial games freely to play on their own consoles. 2. To let gamers make Xbox 360 commercial games that they may transfer over live. But can we sell these games & start a business And where do our limits end & then begin again with Pro I have been trying to start a video game business for years now, working with teams and software, and Microsoft XNA can be a new pedestal for my team and business.   Thanks in advance. Depends on how you set it up. If you use the wired controller for input it could be virtually identical. You ca ...Show All

• graymon UI Development with XNA?

  I'm interested in building a "windows" user interface into my XNA game, however, I'm not finding a whole lot of tutorials or code samples on how best to do this. I want to draw a sprite on the screen, say one that mimics a window, and allow the user to drag it around the screen and resize it when they are on the borders. I've got the dragging feature working by simply polling the mouse coordinates inside the Update method and checking if it's within the bounds of my sprite's rectangle, but I'm not sure if this is a good method or not I figure this is something that has been done many times before so there is probably a "best practice", but I can't seem to find anything on it for XNA. I'm really just looking for confirm ...Show All

• Zulbaric Supported gamepads (Spacewar)

  Hi, Is just the XBOX360 game pad supported, or should other pads also work. I've tried connecting my old MS Sidewinder Plug and play pad, which is working in other programs, but not here. Is there something I need to set up And (if other pads are not supported in spacewar), is this a limitation of the spacewar demo that can be coded around for windows based games Chris If they are using XInput, you have to use a 360 compatible game pad. There are pads other than Microsoft that are 360 compatible, but none of them older than a year. where i can find a list of supported controllers Is there any easy option to play Spacewar with the keyboard . This is my ...Show All

• Nickthegreek DX Proxy Objects and other optimizations

  Hi. This will be my first post here. I come from a Delphi / OpenGL background. Currently doing some development in XNA Game Studio Express. One of the biggest problems I have is to try and translate concepts used in OpenGL to DirectX when it comes to optimization. OpenGL Proxy Objects: Is there a similar concept of this optimization in DirectX Display Lists: Is there a similar concept to complied display lists in DirectX Frustum Culling: Is this something you have to do manually, or does XNA pipeline deal with such culling for you Occlusion Culling: I am sure this works the same as OpenGL in concept, but is there anything special I need to keep in mind I have been out of the ...Show All

• ElectricBliss How can I check whether the mic is connected...

  Hi all...,, I had designed a media player with Recorder in VB.Net 2003... I have one problem with it.. That is when one going to Record without connecting the Microphone means I need to give an alert to user like "You need to connect the Mic for proceeding Record"  for this I need to check the ports get the status of ports... Can anyone give me an idea to resolve this... Regards.., RR. I'm not sure you really can tell or not...maybe by measuring input volume.  But I don't think there's any way to flag if it's connected/ready or not. Indeed. The only way is to capture sound and compare it for silence. Note that even if the mic isn't connected, you mi ...Show All
