• Halaway 3D Model Not Displayed Correctly

  I have a 3D model of a go kart and its textures are not being displayed. The textures have been imprinted into the the .FBX file(merged). all i get is a the model in black. The default lighting is enabled but i think its much more than that. could it have something to do with the file itself or should i add something into my coding Xna is reading the texture files imbedded since i corrected a problem where a textures didnt have the right size 24 * 131(my computer doesnt like this) or something like that so... im stumped as to where the problem is. just for some more info i use Maxon 4D Cinema and then exported it where it automatically imbeds the texture files. Thanx in advance Peter. How are you enabling the l ...Show All

• zhengh writing texture data from one texure to another?

  I am wondering if it's possible to permanently update a texture with the contents of another texture. For example, writing 'bullet hole' textures onto a wall texture. Sure, but the details depend on the memory pools and formats of your source and destination. But “texture baking” is not state of the art anymore. You should use multitexturing or multipass blending instead. You give me a lot of credit to understand those techniques, haha. Is there somewhere I can get more information Unfortunately I don’t know an XNA based sources for these basic technologies. But as a first starting point you could dig a little bit around in the Direct3D documentation: http://msdn.microsoft.com/library/en-us/directx9_c/Direct3D_Tex ...Show All

• wilsonm My first game... Asteroid Defense.

  In this game you are a ship protecting a planet from incoming asteroids. Controls: 360 controller: Left Joystick -- Move ship left and right. A -- Shoot Right or Left Trigger -- Change Weapon. Keyboard Left and Right Arrow Keys -- Move ship left and right. Up and Down Arrow Keys -- Change Weapon Space -- Shoot The weapon you are using is shown in the top left corner. The stronger the weapon you use, the less points you get for destroying an asteroid. Levels progress at timed intervals and more and more asteroids come down. You lose when one of them reaches the planet.

• Geeee XNA losing sync when in full screen mode

  Hello, I'm having a problem with XNA changing the update() speed when I go to full screen mode; in window mode my fps counter returns 60 which is right, my tft runs at 60hz. The problem is that in full screen mode the fps counter shows me 75; it seems that update() is being forced to 75hz somehow, while my tft drops back to the 60hz it can handle....this results in all sprite movement becoming very jerky. I've tried using: this.IsFixedTimeStep = true; this.TargetElapsedTime = new System.TimeSpan(0, 0, 0, 0, 16); to fix the problem but it still happens and I cant work out why, is this a known issue to anyone Have you tried: myGraphicsDeviceManager.SynchronizeWithVerticalRetrace = true; ...Show All

• raghu_grdr chopping up a texture?

  Hiya, I'm currently building a class for card games, and part of that class involves drawing the actual card. It's based around the functions included in cards.dll, basically, the texture is setup the way it would be in cards.dll, e.g. As,Ah,Ad,Ac,2s,2h,2d /..../ 3c,4s 4h,4d,4c /...... 7d,7c,8s /...... 10c,Js,Jh,Jd /... So imagine the cards in the texture are set as 13 columns * 4 rows So, just like cards.dll, if a user use's, say card 4, it would draw the 2s... This is the code I've got, and I've literally tried everything to get it to work:- And I cannot think of anything else! This is just a practice really, for using tilemaps within XNA, so any advice (or even a little source), would be greatly appreciated ...Show All

• Cammyr Sprite Blitting question - Wondering if this is still a problem

  Hi all, When Beta 1 was out I dove right in and started working on a simple demo that moved a sprite with some alpha transparancy around the screen. The way I had it set up was something like this: -I had a class set up for the sprite that I called Player -The Player had a Vector2 for his screen position. -If the user was pushing the left thumbstick in any direction, the Player class's move function was called ,where a new X and Y location was made based on the angle that the thumbstick was pointing. -When Drawing the sprite, I'd get the sprite's screen position vector via a get property. Doing it this way often made my screen position vector have decimal values for the X and Y screen position of my Player sprite. This caused some funky is ...Show All

• Sal1 Using Game (and GameComponents) in a Windows Forms editor?

  Hi I just started looking at XNA, and I've assembled a small team for the DBP contest. The first thing I'm trying to do is to make the game run inside an editor, because I'm pretty sure it'll be very useful. However, looking around at the different solutions that people have come up with for running XNA in a control, it seems none of them are using the Game class. And on Shawn's (who is a developer of the XNA framework ) blog, he writes: "If you want to render into a custom window, don't use the Game class. It will be much easier and more reliable to directly create your own GraphicsDevice object." This, in turn, makes it impossible to use GameComponents. But it would be nice to use GameComponents that other people have created ...Show All

• SgtDuty Single letter prefix before a variable

  I was wondering if anyone can point me towards some information on having a single letter prefix before AND after a variable name.
