• 0vZ Numeric performance on 360

  A question for the framework/VM guys... I have ported one of my simpler benchmarks to the 360, and find that the numeric performance is running 5x slower than my 2.8GHz P4 desktop. Now I was expecting a drop in performance on the 360, allowing for the difference in CPU implementation (in order execution / branch prediction etc), but nothing like this magnitude! The benchmark simply transforms a source array of Vector4s to a destination array of Vector4s, using a 4x4 matrix. Have you guys done any benchmarking of pure numeric perf, and if so is this in line with what you get Andy. andreww wrote: You might want to read this in order to get some ideas about why numeric performance is lowe ...Show All

• JimM5 Models drawing in front of Sprites

  I have one class, GameScreenManager, handling all of my 2d images. I have another, GameLevel, handling all my 3d assets (models). Both of these are drawable components, added to the Game. Both classes are drawing their graphics appropriately, but the 3D graphics are always occluding the 2D. I have set: GameScreenManager.drawOrder=2; GameLevel.drawOrder = 1; and have tested to show it is in fact drawn in the order I tell it. I have tried setting all my 2d graphics' LayerDepth to both 0 and 1 when Drawing (not sure which value means 'closest to player') and neither value changes anything. How can I tell my 2D Sprites, "draw on top of all other graphics no matter what" I don't know if this will change anything, but tu ...Show All

• ironox Low FPS problem

  Hi, I'm making a terrain editor usinv MDX. The terrain is basically a mesh consisting of rectangles (2 triangles) per subset. The problem is that when I make a terrain larger than 20X20 (so 800 triangles and 400 subsets) my fps falls to about 15-20. Removing textures doesn't help. Here is the simple bit of code for terrain drawing: public void Draw() { for (int i = 0; i < TerrainMesh.GetAttributeTable().Length; ++i) { device.SetTexture(0, Textures ); device.Material = Materials ; TerrainMesh.DrawSubset(i); } } I also get  the same bad FPS if I exclude these lines from my PresentParameters settings:  PP.AutoDepthStencilFormat = DepthFormat.D16;  PP.EnableAutoDepthStencil = true; I would to hear ...Show All

• Pieter Versteijnen Game and GameComponent Feedback

  We've been combing the forums and the Connect database for bugs, feedback and suggestions around the application model. We still have a small amount of time to consider any other feedback you may have. So this is the thread that you post your latest likes or dislikes with Game, GameComponent, services, etc. Please scan the other threads before posting here, I'd like to just gather things that haven't already been discussed or reported elsewhere. Thanks! May be .. One thing which i find rather strange is that the Game.Starting event seems to be raised after GameComponent.Start has been called. I only discovered this as i initialised the AudioEngine, SoundBank, etc in Game.Starting, but it was null in the Gamecomponent. ...Show All

• Sweeps78 Microsoft.Samples Samples is not a member of Microsoft

  When I'm trying to use the Microsoft.Samples.DirectX.UtilityToolkit in Visual Basic Express, an error pops up saying that samples is not a member of microsoft. :(  I don't  understand what the problem is  I already downloaded the new directX SDK. Thanks Sorry for being a newbie but how do you make a .dll with Visual C# Express The DirectX utility kit is written in c# and therefore will not compile in VB Express. If you want to use Express products you need to get c# express (also at the bargain price of $0) and compile the DXUT classes to a class library. Then you can reference this class library from VB Express. Start a new class library ...Show All

• Jeanne P Help me on How to fire a sprite to a mouse position from another Sprite

  Hi again, this time i need some major help. I'm creating a shooter arcade, and the biggest problem i ran into so far was getting the sprite to fire towards my mouse positioned reticule. Could I please get some information on how to tell the game code that i want the sprite to move towards the mouse x,y from it's fixed positions. Thx for your help. One way to make one object "follow" another. 1) Create a new 'direction' vector as the difference between the two object's positions (object1 - object2) 2) Normalize the resulting 'direction' vector. This will create a 'unit' vector with no magnitude. 3) Negate the direction vector. This will set the direction of object1 to face towards ...Show All

• fode Hosting an XNA Game in a WPF Application

  I was wondering if it possible to host an XNA Game within a WPF Application. I played around with the idea a couple months ago, hoping to use the same method one would use to host a Windows.Forms application within a WPF application, but I was unsuccessful. Does anyone know of a straightforward way to do this, if it is indeed possible I realize there are 'airspace' issues that would prevent me from creating a WPF interface that would overlay the XNA content, but I can live with that. I'm developing a 2D turn-based strategy game, and at some point I would like to add a 3D tactical combat system. I'd love to do this with XNA. Cheers, Mike Your XnaControl looks interesting Joel, I'll have to give it a ...Show All

• carlp22 XNA Game Confusion

  Just to give you a little background. I am new at game codeing. I have done buisness apps for 8 years in vb to vb.net. I have started to learn c#. I download xna and did the first tutorial, got a bouncing bmp file. So I have some questoins, sort of big general questions. I do not understand the architect of a game program. There are some big concepts that I am missing from xna. For example the loop that the tutorial refers to. I do not understand these methods and the significance of them: Update Draw There is a Program.cs file that gets called and there is the class file that is partial that gets called that has these methods. Please help I want to learn. Thanks everyone for the i ...Show All

• JeremyAtGosub 3D Points

  Hi everyone, I am working on my Direct3D project and I have question about drawing 3D points in Direct3D. I want to draw 3D points that have more than one pixel. Just like SetWidth() in Line class. Any hints would be appreciated. Hi Wessam, Thank you very much for your info. With SetWidth() in Line class, I can make lines thicker and these thickness is not change when I zoom in and out the screen. I want 3D points to be the same. Will the vertex shaders provide what I need thanks Point sprites work just like this. And with vertex shaders yes you can write your shader to do whatever behavior you want... Use point sprites if their restrictions are ok with ...Show All

• Marcelroos Smooth movement

  I did a "game" where a ball bounce around the screen. It's running at 60 fps but it isn't a smooth movement. It's an issue from XNA Framework Beta I am working with SpriteBatch class...

After disabling the 2nd monitor it's now smooth. Maybe my results are unique, but I'd hazzard a guess that XNA beta doesn't play well with multi monitors.
