• Chris Wilson Collision Detection With Bezier Curves

  Hi, I'm currently making a small 2D game in XNA Game Studio Express. It involves a player moving around a terrain and being able to collide with it. Nearly all the graphics and settings in my game are user generated so this allows for everything to be quite customisable. For collision detection the user specifies paths made of Bezier curves which are stored in a file. The game reads this file and stores a number of points on the curves in an array. The player is also made of Bezier curves that are converted into points: This shows how I want collision detection to happen; if any of the lines that make up the player intersect with any of the lines that make up the terrain, then a collision has occurred. Once a collision has occurred two t ...Show All

• FixingTheHoleInTheOcean ExternalReference<CompiledShader> - Am I missing something?

  I'm trying to create references to .fx files from my Content Pipeline types (my writer). When I build my level objects, I want the references to textures and effect files to be baked into the object so that you don't have to add .fx and .png files to your project, just add the file that processes into a level. (A .bsp in my case). My problem is that I used this thread to create external references to textures, but the same technique does not work for shaders. Psuedo code in the processor: ExternalReference<EffectContent> source = new ExternalReference<EffectContent>("C:\shader.fx"); ExternalReference<CompiledShader> built = context.BuildAsset<CompiledShader>(source, typeof(EffectProcessor).Name); ...Show All

• Johan Nordberg shader 1.1 or higher?

  everytime i hit f5 to build and debug my program it always gives me this error........"Could not find a Direct3D device that has a Direct3D9-level driver and supports pixel shader 1.1 or greater." does anyone know how i can take care of that problem. I downloaded the DirectX SDK and all the other stuff but its still giving me that I believe that's similar to a GeForce 4 MX, which is similar to a GeForce 2, which doesn't have shader support. You probably need to upgrade. What graphics card do you have If you have an old card (like a GeForce 3), it probably doesn't have shader support. Unfortunately, if that is the case, then the only way to solve the problem is to buy a new card. Althou ...Show All

• Matt Greenwald using the XmlImporter w/Content Pipeline

  I have all my game objects defined in XML files and I would like to use the Content Pipeline to load them. Looking at the available importers, it seems like the XmlImporter is the right choice, but it appears to want the XML in a certain format (a reasonable requirement). So far I haven't found any documentation on the correct way to format the file. It seems like this would use the XML serialization in C# to serialize/deserialize the object. When you pick XmlImporter in the properties, however, it appears to want a particular root element. Also, I would assume that you would use the No Processing Required for the Content Processor. If that is the case, then I think it is just a matter of formatting the XML file correctly, selecting the XM ...Show All

• papermater How to interact with 3D world using mouse?

  Hi! I want to move the camera translatory with the mouse. I also want to determine 3D world coordinates of the point that was clicked by user, on the plane notmal to camera vector. Camera's height i.e. distance from mentioned plane is vvariable and controlled by user. Whole D3D scene is rendered on a panel control. I am using C# and DirectX 9b. I'd appreciate any help! Thanx in advance! Thank you, I resolved my problem. The thing is, I should have used orthogonal projection from the start. This way, it all bils down to simplest math, knowing that in my 3D world there is only a single plane that is normal to camera's vector. Translating should be pretty easy ...Show All

• ZackL Help Using Quaternion To Find Target

  I've read a couple of very helpful threads here on Quaternions, so I decided to try putting them to use. I was able to use them to move a 3D object around using a modification of Riemer's flight simulator tutorial, to which I added a second object. However, I then tried to initialize the orientation of the two objects to point towards each other from any given starting location, and that didn't work the way I expected. Can someone help me understand what's wrong with the following code public void SetOrientation(Vector3 startLocation, Vector3 targetLocation) { Matrix target = Matrix.CreateLookAt(startLocation, targetLocation, Vector3.Up); Orientation = Quaternion.CreateFromRotationMatrix(target); } public virtual void U ...Show All

• K. Ravinder Reddy Custom Content Processor - Usage

  Hi, I am looking from some advice on writing a custom content processor for XNA. I have been working on a tile engine and have my Windows based tile map editor up and running. This editor produces an XML file holding all the tile set bitmaps, a list of all the levels in the map and a list of layers on each level. I am thinking of using a custom content processor to load this XML file, parse it and serialise it to the xnb file. I then plan to write a custom importer which will create a top level map object which will hold the tile sets as Texure2D objects and a dictionary of levels in the map. Does this seem like the correct use for a content processor Andy This is absolutely a great way to empl ...Show All

• Supernaut Local Texture References Vs. ContentManager.Load

  Many examples, both in Help Contents and not, access Texture information in various ways. Most create a local reference to the texture: private Texture2D texture; Which is then used in a Draw method: public override void Draw( GameTime gameTime) {     this .spriteBatch.Draw( this .texture, Vector2 .Zero, Color .White);     base .Draw(gameTime); } The Microsoft.Xna.Framework.Content. ContentManager stores loaded texture information in a private Dictionary<>. Would it be inappropriate to reference a texture from within the Draw method via the ContentManager   This of course requires the texture is initially -- and when necessary -- loaded in the Loa ...Show All

• Jesper Ekenberg Post-Processing Shaders and Layers?

  I want to create 2D sprite scenes in GSE the way you work with layers in Photoshop. This is an example of a scenario of what I would like to achieve: Say, I have 2 layers of background and 1 layer of foreground. The first background layer is a sky with a sun. I want to blur this layer with a PixelShader. The second background layer is trees. This layer I also want to blur, but not as much as the layer beneath it, for a Depth of Field effect. The foreground layer contains the grassy ground and the player sprite. On top of all layers I want to put a glow effect from the sun also with a PixelShader. The glow effect should use a Glow Alpha texture that will be "deformed" by the layers, if something is covering the sun those pixel in the Alpha ...Show All
