    - 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 Tag: XNA Framework Blending Multiple RenderTargets to the BackBuffer (Another RT) Game Technologies: DirectX, XNA, XACT, etc.

    - Custom soundtracks I've only had XNA Game Studio Express since yesterday, but I've been having a lot of fun with it. I've started working on a game which is coming along nicely, but one thing irks me - I can't figure out how to have music playing that stops when a user chooses a custom soundtrack instead. At the moment, when a user chooses their own track is starts playing fine, but the game soundtrack continues to play in the background. I'm sure I've missed something simple, but I can't for the life of me figure it out. Any hints would be much appreciated.

    - Whats the deal with DirectX being owned by XNA? How come when I go here: http://msdn.microsoft.com/directx/ I get redirected here: http://msdn2.microsoft.com/en-us/xna/aa937781.aspx Is XNA making a move on owning DirectX It seems after reading some basic information on microsoft.com regarding recent statements about XNA and its current goals I'm led to believe that perhaps the whole of DirectX is being cut up and fed to XNA. First DirectShow goes. Now I realize even basic support I had in DirectX 9.0c is not even supported in DirectX 10. Basically I'm gonna have to port a graphics app engine from DX9 to DX10 and have to include DX10, at least some DX9 headers/libs, the seperate DirectShow files, and if I want rumble support for my Wireless XBox360 controller for Windows I need to include XInput because DirectInput doesnt have that support. Anyhow, I'm just curious what the future of DirectX vs XNA is. Who will own who within the next 5 years. If this question is in the wrong forum please redirect.

    - Bug in BoundingFrustum.Contains()? If i write the following code: BoundingFrustum f = new BoundingFrustum(new Matrix(1, 2, 3, 4, 5, 6, 7, 8, 9, 8, 7, 6, 5, 4, 3, 2)); Vector3 vector = new Vector3(1,1,1); BoundingBox box = new BoundingBox(vector, vector); ContainmenType t; t = f.Contains(vector); Console.WriteLine(t); t = f.Contains(box); Console.WriteLine(t); I'd expect both to give the same answer. Either both are contained or both are disjoint. However the Frustum contains the point but the box is disjoint.

    - DXT compressed Textures Hi, in general it looks like there are the same DXT texture compression formats as for DX9. I assume those compression formats do not work with the new DXGI_FORMAT_R9G9B9E5_SHAREDEXP & DXGI_FORMAT_R11G11B10_FLOAT formats In real-life (TM) I always have to store texture data in DXT compressed formats ... if I want to opt for a better color quality in compressed formats, nothing seems to have changed between DX9 and DX10 ... is that correct Thanks in advance, - Wolf Tag: XNA Framework Blending Multiple RenderTargets to the BackBuffer (Another RT) Game Technologies: DirectX, XNA, XACT, etc.

    - ODD Bumpmap issue I have bought a book on shaders and have been going through the tutorials with some success. However I now have a rather odd issue with my bumpmap shaders... I have three shaders, a bumpmap shader, a parallax bumpmap shader and a self shadowing bumpmap shader. My issue is that when I run my engine with the bumpmap shaders I get a rather odd effect happening, but (after many days of trying to sort this out) I found that if I run FX Composer prior to running my engine, this oddity seems to go away. This leads me to think that FX Composer is setting some render states that I am not aware of and need to set for my bumpmap shaders. Is anyone able to let me know what render states I need to set or even if this is what is causing this odd behavior My shaders before running FX Composer http://www.randomchaos.co.uk/XNA/Examples/before.jpg My shaders as FX Composer is running http://www.randomchaos.co.uk/XNA/Examples/during.jpg My shaders after FX Composer has ran http://www.randomchaos.co.uk/XNA/Examples/after.jpg Here are the shaders: Tag: XNA Framework Blending Multiple RenderTargets to the BackBuffer (Another RT) Game Technologies: DirectX, XNA, XACT, etc.

    - Rendering hundreds of models How do games like Medieval: Total War 2 render hundreds of skinned models running different animations on the screen and still run at a good frame rate Is it possible that the models are not skinned I can't get more than 100 skinned models (matrix palette size = 50, verts = 5000) to run without getting a noticeable frame rate hit. This has to do with the fact that I am using shader instancing and doing 100 draw methods. I confirmed this by taking out all the animation and update code and only calling draw 100 times every frame. It's possible that my shader is inefficient (the DirectX examples split the shaders up based on influences per vertex), but I don't think it would be that huge of a difference. My skinning function is very similar to those in the DirectX sdk: SKIN_OUTPUT Skin4( const VS_INPUT input) { SKIN_OUTPUT output = (SKIN_OUTPUT)0; float lastWeight = 1.0; float weight = 0; for (int i = 0; i < 3; ++i) { weight = input.weights[ i ]; lastWeight -= weight; output.position += mul( input.position, MatrixPalette[input.indices[ i ]]) * weight; output.normal += mul( input.normal , MatrixPalette[input.indices[ i ]]) * weight; } output.position += mul( input.position, MatrixPalette[input.indices[ 3 ]])*lastWeight; output.normal += mul( input.normal , MatrixPalette[input.indices[ 3 ]])*lastWeight; return output; }; The only way I can think to speed up performance is to store the interpolated keyframes in a texture (would have to be huge) and use shader 3.0 hardware instancing to designate the starting pixel location for the matrix palette in the texture. I don't even know if this would work (and I don't know how I would get it to work with dynamic keyframing), and somehow I doubt that this is how modern games solve this problem. Does anyone have any advice I've been suffering for a while trying to solve this. Thanks!

    - Question on deferred shading with normal mapping Hello, I am currently working on my deferred shading engine and have run into an interesting problem concerning the usage of normal maps. At the moment I am storing the normal for each pixel in world space during the geometry pass. All of my lighting calculations are also being done in world space. The problem I am having is it seems more people seem to do normal mapping in tangent space. In fact I've only ever read 1 article on doing it in anything other than tangent space. To address this problem I was thinking I'll just store all of my normals in tangent space instead of world space when I do the geometry pass. This seemed like an even better idea once I realized I would need the normals in tangent space for parallax occlusion mapping anyway. The problem is when I render my lights as a post process I have to convert them into tangent space as well. Since the tangent space matrix is per-vertex I saw no way of doing this without storing the binormal and tangent for each pixel as well (ack!). My second thought was to simply continue storing normals in world space by multiplying the normal map normals by the inverse of the tangent space matrix. Unfortunately this would be an extremely expensive operation as I would have to calculate the inverse in the pixel shader (unless I am missing something). I am wondering does anyone have any recommendations on this problem or should I start encouraging my art team to produce all of our normal maps in world space P.S. It's the 11th now w00t *dances a little jig*.

    - Rectangle collision detection help Hi, I'm learning how to use collision detection in sprites, and I've decided to use Rectangles. Basically, I program the game to make a rectangle around each of the 2 sprites and, when I move the sprites via keyboard input, it moves the box with them.( Now, I'm doing this to test collision detection. Heres the bit of code that doesn't work: if(Sprite1box.Right == Sprite2box.Left) { Sprite1pos.X += 5; Sprite1box.X += 5; } (Where Sprite1box = The rectangle aroudn the first sprite, Sprite2box = the rectangle around the 2nd sprite, and Sprite1pos is the vector of the 1st sprite) This doesn't work - the sprite just moves right through the second sprite. Now, I figured I must've done something wrong with the rectangles. But when I do: if (Sprite1box.Bottom == Sprite2box.Top) { Sprite1pos.Y += -5; Sprite1box.Y += -5; } It runs fine; the sprite doesn't go below the top of the Sprite2box.

    - Any suggestions for defining direction of partical effects on a 3D model? Hi all: I'm still playing around with XNA and figuring out what I can do with the current state of the technology. What I want to do is have a 3D model of a spaceship that has RCS thrusters and a main engine. The RCS thrusters and main engine will all have a particle stream to simulate rocket exhaust. Somehow, I need to define the size and type of rocket exhaust, and what direction it should take, and do so within the context of the XNA framework. I presume I'd need a custom processor for the model to identify where rocket exhaust nodes are (think named invisible cubes in the 3D model, like "MainEngine" and "YawRight"), but I'm stumped on how to define the direction of the particle stream in relation to the model itself. Perhaps something like "YawRightPort" means shoot the stream to the left, whereas "YawRightStarboard" means shoot the stream right.

    - Optimized graphics question: Which is better? I'm in the process of developing an XNA game and am currently documenting the artwork portion of the game. I am specifically interested in optimizing the art assets so the game performs as best as possible. The game I am working on will target 720p as its native resolution. Of course, in the interests of compatibility, I'd like the game to support lower resolutions as well. My question is (seemingly) simple. Should I have the artists create assets targeting native 720p resolutions and scale downward in code or vice versa In addition, if creating small graphical assets is the way to go, what recommendations do you have for creating assets that scale well enough to appear as HD content. Now, I'm assuming the latter is a loaded question and am happy to RTFM of any resources anyone suggests. Hopefully I am not asking for world peace. :) TIA! - Robert Tag: XNA Framework Blending Multiple RenderTargets to the BackBuffer (Another RT) Game Technologies: DirectX, XNA, XACT, etc.

    - Problems with rendering... Hey, I'm pretty sure that these are both simple fixes.... But I've been having two problems with rendering things with direct x 9. I've worked around both of them for a while but I don't really like doing that, although I've been unable to come up with a reason/solution for either and my research on google and these forums hasn't yet provided a solution, so I figured I'd actually try asking for help... I'm writing a 2D/3D engine, and I've found that when I'm using 2D rendering, nothing shows up on screen until I render a font to the screen. I'm not doing anything excessive with my fonts - I'm just using the LPD3DXFONT class with the DrawTextA function to render my text. So as far as I know, that shouldn't be changing anything important. Regardless, until I've rendered a font to the screen, none of my 2D sprites will show up on screen. I'm using the following render states: m_pDevice->SetRenderState(D3DRS_LIGHTING, false); m_pDevice->SetRenderState(D3DRS_ALPHABLENDENABLE, true); m_pDevice->SetRenderState(D3DRS_SRCBLEND, D3DBLEND_SRCALPHA); m_pDevice->SetRenderState(D3DRS_DESTBLEND, D3DBLEND_INVSRCALPHA); m_pDevice->SetTextureStageState(0, D3DTSS_ALPHAOP, D3DTOP_MODULATE); EDIT: okay, apparently half of my message disappeared. So let's try this again... In case it's relevant, here's what I'm using to set my projection matrix: D3DXMatrixOrthoOffCenterLH (& m_mtxProjection , 0, 1, 1, 0, -100, 100); Other than that, there really isn't any difference between my meshes and my sprites (other than the fact that one's a textured quad and one's a full fledged mesh). The other problem I've been having is that in release mode, nothing shows up on screen even though everything works fine in debug mode. I'm not quite sure why this is happening. So any insights as in to why that happens would be much appreciated :) Tag: XNA Framework Blending Multiple RenderTargets to the BackBuffer (Another RT) Game Technologies: DirectX, XNA, XACT, etc.

Ok. I am trying to write a SceneManager that contains a list of RenderGroup. Each RenderGroup is responsible for rendering a set of items (models, etc) to a RenderTarget and then rendering their RenderTarget to the BackBuffer (in this case a RenderTarget that SceneManager sets).

The Problem: Blending between RenderTargets is not working. I have it working so when a RenderTarget is rendered multiple times with separate passes in the PixelShader it blends in Add mode. Between to RenderTargets, or RenderGroups in this case the blending fails. No matter what order I have the RenderGroups setup, it just won't blend correctly.

Here is a picture of what I am trying to do:

Here is the code...

RenderGroup: https://opensvn.csie.org/viewcvs.cgi/Windows/Xna5D/Xna5D.Graphics3D/RenderGroup.cs root=Xna5D&view=markup

SceneManager: https://opensvn.csie.org/viewcvs.cgi/Windows/Xna5D/Xna5D.Graphics3D/SceneManager.cs root=Xna5D&view=markup

Game1.cs: https://opensvn.csie.org/viewcvs.cgi/Windows/Xna5D_PostProcessing/Xna5D_PostProcessing/Xna5D_PostProcessing/Game1.cs root=Xna5D&view=markup

Or maybe there is a better way to go about this

I figured it out... count is 2 times now that I have made a stupid mistake. I wasn't keeping the master RenderTarget alive, plus I was clearing it on every RenderGroup for some odd reason.

I also had to change the RenderState setup a bit.
