    - sollution Hi guys I want to implement an easy-to-manipuate texture in my game-engine. therefore i've created a bitmap in memory and a D3D texture. the user can use GDI functions to draw on the bitmap and the bitmap must be updated to video memory. I wrote the following routine (It's pascal, but i think most of you will get the idea): [code] //create sysmem texture HR := D3DXCreateTexture(Graphic.fD3DDevice,fWidth,fHeight, 1 , 0 ,D3DFMT_A8R8G8B8,D3DPOOL_SYSTEMMEM,fSysTex); if Failed(HR) then begin Result := E_TEX_CREATE_FAILED; LastErrorDX(Result,HR); Exit; end; {Get first surface} HR := fSysTex.GetSurfaceLevel( 0 ,Surf); if Failed(HR) then begin Result := E_TEX_SURFACE_FAILED; LastErrorDX(Result,HR); Exit; end; //lock entire surface HR := Surf.LockRect(D3DRect,nil,D3DLOCK_NOSYSLOCK); if Failed(HR) then begin Result := E_TEX_LOCK_FAILED; LastErrorDX(Result,HR); Exit; end; //set alpha to 255 so every texel is visible (this is not done by default) //scanline returns a pointer to a pixel row for i:= 0 to fbitmap.Height- 1 do for j:= 0 to fBitmap.Width- 1 do (PChar(fBitmap.ScanLine )+(j* 4 )+ 3 )^ := Char( 255 ); {move the data from fBitmap to fTexture} for i:= 0 to fBitmap.Height- 1 do Move((fBitmap.Scanline )^,(PChar(D3DRect.pBits)+(D3DRect.pitch*i))^,fBitmap.Width*4); Surf.UnlockRect; //update texture to VRAM HR := Graphic.fD3DDevice.UpdateTexture(fsysTex,fTexture); if Failed(HR) then begin Result := E_TEX_UPDATE_FAILED; LastErrorDX(Result,HR); Exit; end; Surf := nil; [/code] But i use mipmapping and that's where the problems begin. The mipmap chain doesn't get updated somehow. It looks like the changes applied on the bitmap slowly fade away in the smaller texture surfaces. I dont know this for sure, but it doesn't look good. image 1 image 2 The red rectangle on the texture is the updated part. Even when i look with an almost 90 degree angle onto the texture, it still doesn't have a solid red color. :( I think i need to make sure that the smaller texture surfaces (lower in mipmap chain) also contain valid data. So i need to regenerate the chain. Do i need to do this by hand or are there any tricks/methods available to let D3D do this for you. I really hope someone (a very kind DirectX MPV) knows a simple sollution for this problem. This stuff really bothers me... i just want to continue my project. Does someone know a sollution for this any help would be greatly appreciated. ;) Tag: Game Technologies: General How to fix ForceFeedback bug in C# DirectInput Samples Game Technologies: DirectX, XNA, XACT, etc.

    - Setting project up to be cross platform This is like #1 for me right now. Development goes a lot faster staying on the PC. Plus the xbox on my desk makes noise. . . I'm looking at sharing code via assemblies now. Platform-specific stub projects with the bulk of the code in a shared assembly is certainly an acceptable work-around for me.

    - Render transparency with shaders The first step is to set the alpha blending renderstates as Joel describes. Then, you just need to make sure your shader outputs whatever transparancy amount you want as the alpha component of the color returned from your pixel shader. If you are using BasicEffect, you can control this either by putting per-pixel alpha data in your textures, or globally by setting the Alpha property on the BasicEffect instance. If you have your own shaders, you'll need to modify them to output whatever alpha value you want.

    - Xbox 360 Storage location/access Not sure what your goal is, if you want to transfer game saves to pc, there is the Datel Xbox 360 / Xbox Transfer Kit http://www.ebgames.com/product.asp product%5Fid=802323 Nyko makes something that supposely let you attach USB devices to 360: Nyko Xbox 360 USB Multitap & Card Reader http://www.ebgames.com/product.asp product%5Fid=802273 Zune suppose to show up as a storage as well. I don't have any of the above, so can't vouch for how well they work. If you want direct access to USB (i.e. to control your Roomba or whatever), then there isn't an api for that (yet ). It would be cool to be able to access your own USB hardware. Tag: Game Technologies: General How to fix ForceFeedback bug in C# DirectInput Samples Game Technologies: DirectX, XNA, XACT, etc.

    - C# - Managed DirectX - Secondary Monitor Hi, Thanks for your reply. The problem I have isn't so much with debugging, because it does run on the seperate monitors. But, if for example with code similar to that you have suggested, I do enter a breakpoint in Visual Studio...even though shown on the seperate adapter it still minimizes when running in fullscreen mode. I can have the DX device initialised to run in window mode (which appears fullscreen, with removed borders and controlbox)...but it performs too slow. When running fullscreen it performs fine, but the end-user cannot use Microsoft Access (or any other program) whilst the DX device is shown on the second device (in fullscreen mode). Somehow I need to get my program to run fullscreen, whilst allowing the user to interact with Windows on the primary monitor. The program I am creating is not directly interactive in anyway, and never actually requires keyboard or mouse focus. It acts as an output for and Access database, and automatically recognises when changes have been made. This part works fine. There is something in the DirectX SDK which is forcing itself to minimize when something happens outside. The same effect happens in commercial games, so if you were to have a game running on one monitor and outlook on another. Clicking on an email in outlook would cause the game to minimize. Usually this is understanbable, but in my program I need to allow the user to work on device 0 whilst my program does its own thing on device 1.

    - Alphablending 3D I've actually read that and found it informative. However, I am interested in a full 3D approach. Note this: Since this is a 2.5D game, and the player has no control over the camera, I know that objects in the foreground will always be in the foreground, and the background objects will always be the background. So, I can just hardcode my objects’ draw order I'll look on GameDev and Gamasutra and the like and see if I can find anything.

    - Tiered Architecture for games I know in business application usually 3-tier architecture is used to develop business applications, I was wondering if anybody ever thought of using an architecture model for the development of a game. For instance the 3-tiers are Presentation, Business Logic, and DataAccess... I suppose the game would have DataAccess but instead of SQL it would load from files (File I/O) You could even use XML serialize/deserialize Instead of business logic you would have game logic, presentation is the graphics for the game... a loop of the game (architecturally) would have to reference all layers.... show_menu(); //presentation load_player(); //DAL data access layer load_level(); ///DAL game_engine.run(); //run game, this in turn uses the layers in its own loop (load meshes=DAL) save_player(); //level, health, items (DAL) to file //the code would be more OOP i'm just thinking about it architectually because i always think of making a game, but then i stop in the middle because i didn't plan its architecture out too well... by planning out these details i think it would save time and be more understandable. Does anybody use an architecture model when they piece their game together Or do you just wing it Tag: Game Technologies: General How to fix ForceFeedback bug in C# DirectInput Samples Game Technologies: DirectX, XNA, XACT, etc.

    - Could C# be the future of gaming? With the ability to use unsafe code in C#, I expect performance to not be an issue in any game other than cutting edge stuff. There will probably always be those that will prefer C++ over anything else, but I can see a move by smaller companies to C#, for the increased speed of development if nothing else.

    - VerifyCanDraw throwing a NullReferenceException Ok, you can get it at: http://mail.rochester.edu/~mabernet/trans2d/downloads/samples_011806.zip As I said, it's kind of big...Trans2D is a 2D graphics library I'm working on, and Samples contains a number of sample applications using it. FontImport contains a pipeline extension you'll need to build anything in Samples. Let's focus on the Hierarchy application: try running it in vcse with no breakpoints. It should run fine. Now go into the bin folder and run the debug version, and it will throw an InvalidOperationException stating that Effect.Begin() was called twice in a row. Now, the natural thing to do would be to step through it in the debugger and see what's up, so add a breakpoint in Transform.Draw(). If you follow it for long enough, you'll see it step into a block from which there is no apparent return without calling Effect.End(), but before it gets there, VerifyCanDraw throws its exception from inside the DrawIndexedPrimitives call in Transform.cs, line 848. So this happens before I even get a chance to see what causes the Effect.Begin excetion (and, incidentally, if I catch the exception thrown by VerifyCanDraw...nothing happens at all!!) This bug has completely defeated any intuitions I have about debugging. Actions that should not change anything change things, the same assembly throws different exceptions depending on whether I'm running it from vcse...the only guess I have is that the VerifyCanDraw exception has something to do with windowing / the visibility of the window at certain points in the program, since that's the only thing that I can imagine stepping through with breakpoints would change, but I really don't have a clue what. Anyway, thanks for reading, this is really the only major thing holding me back from releasing my library so I am very grateful for whatever help I can get :) Thanks, Max EDIT: it appears that if I cause the device to reset after doing all of my initialization, the exception doesn't happen. I've looked through my code that gets executed on reset and haven't been able to find anything that even changes. It's nice that things apparently work now, but this fix is just voodoo, I really want to know what's happening :( Tag: Game Technologies: General How to fix ForceFeedback bug in C# DirectInput Samples Game Technologies: DirectX, XNA, XACT, etc.

    - When to stop a Quaternion.Slerp? What I want to do is rotate one object to match the arbitrary orientation of another object. So if Ship1 is pitched up 20 degrees, rolled left 45 degrees, and yawed right 15 degrees, I want Ship2 to rotate itself however needed until its roll, pitch, and yaw match that of ship1. Thus far, a quaternion slerp does the job. To control the rotation rate, I'm specifying the amount to interpolate. But, I don't know when to stop calling the slerp method... roughly when the quaternions are equal is what I want. Perhaps there is a better way to determing how to rotate Ship1 to match the orientation of Ship2, when both ships have an arbitrary orientation I'm definitely new to 3D math.

    - access texture NAME for a an FBX-loaded effect I have a mesh with a multi/sub material on it. There are three different sub-materials, each with a different texture. I export via FBX. It comes in as a mesh with 3 parts (naturally.) I want to dynamically replace the texture on ONE of those parts. I need to be able to find the original name of either the material or the texture from the Max file in order to identify which texture to replace at runtime. I found a name parameter on the texture, but it is empty (despite being populated in Max.)

    - Get the VID/PID from an XInput device Sorry, maybe I didn't explain clearly enough. I'm not interested in 'loooking for a certain controller'. I was just detailing an attempted work around to my problem.. I just want to access the device ID's so I can detect what type of controller is connected past the basic types listed in the CAPS.. This is for the purpose of auto-configuration and illustration (rendering appropriate models, etc). For instance, in one project I need to detect the Guitar Hero X-Plorer id. There is currently no way to ident the controller as the XPlorer as it does not have a subtype in the API. I need the controller to behave very differently between the XPlorer and the regular gamepad. In another project where I've also run into this problem I wanted to detect various controllers specifically (including the DOA stick/etc) so I could render little models to illustrate the controller the user was holding.. Just as a presentation thing.. I'm sure many more controllers will apperar, particularly gimmick controllers that MS will not add entries for in the CAPS (or not immediately anyway), and the ability to query the hardware ID would solve all these problems.. Just the VID/PID, it would not need to be any more involved than that.

    - Exception handling in c# General rule: If something is an error, use an exception. If something is not an error, do not use exceptions. If you find yourself throwing exceptions so much that this becomes a performance problem, ask yourself, why are errors occurring that often That's probably a sign of a design problem in your engine, since errors really ought to be unusual (usually a sign of a programming mistake) rather than something that frequently occurs while the program is behaving correctly.

    - Is ApplicationSettingsBase availible for 360? I am writing a game engine using GSE and have come across a interesting quip. I have my engine as a windows class library. and I have my engine as a 360 class library. The 360 project source files were simply linked from the windows version via "Add existing item > Add as link". I did this to ensure that the windows and 360 versions used one code base and to help produce code that would run on windows and the 360 seamlessly. But I have ran into a problem.... The windows version uses a settings file app.config and has a number of pre-specified settings that I have setup by going under the project properties and selecting the "Settings" tab. I have also duplicated the settings under the 360 version of the class library, BUT I get a compile err stating that "Error 1 The type or namespace name 'ApplicationSettingsBase' does not exist in the namespace 'System.Configuration' (are you missing an assembly reference ) ..." when I try to compile the 360 version. I have also made sure all needed references have been added to the 360 version of the class library, and have used object explorer to try and find the ApplicationSettingsBase object in the 360 specific references but I could not find it. So my question is, "... on the 360 side of things does GSE and XNA support the use of application Settings and if not why is the Settings tab even availible under the project properties if it can't be used. Any insite or comments would be greatly helpfull because I really don't want to have to go back and write my own settings system.

    - Effect file parameters If data is black, then the pixel shader is outputting black. This could be for many reasons, such as not finding a texture when texturing, not calculating lighting correctly, some input parameters being 0, etc. In general, to debug drawing problems, I find that Pix for Windows is very helpful. Bind some hotkey to "dump single frame," then have Pix start the program. Dump a frame, and quit the program. Now, step through the drawing command stream until you get to your problem area, and investigate the device state -- constants, textures, bound data, etc. You can also right-click on a pixel and choose "debug this pixel" to debug the pixel shader (although at assembly level).

Hi there,

This thread started here:

http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=985980&SiteID=1

but It was marked as "answered" without a clear solution. Although many people probably found a fix elsewhere, I opened a new thread because this can be useful for somebody.

Some devices, like the Logitech G25, fail to initialize Force Feedback when using the DirectInput Samples for Managed Code. Others, like the Logitech Driving Force Pro, don’t present this behavior.

I talked with Logitech’s engineers and we found that it’s due to a couple of bugs in the Microsoft DirectInput Samples. The whole thing is explained in my blog:
