• Robbie Page Blitting?

  I've checked through the XNA Documentation, but there doesn't seem to be any way to 'blit'. For those of you unfirmiliar with 'blit': Blit is a way to draw something. For example, say you create a "Texture2D" variable, set the size etc... But the texture is blank. The normal way to create a texture to this is to load up a bitmap image with it through the ContentManager, right But what if you want to use a whole sprite-sheet with many images Back to the blank, say, 65 x 65 bitmap image, you obviusly don't want this 2D image of the player to be a whole 1024x768 sprite-sheet. So this is where I used blitting in other programs, it basically asks for the x, y co-ordinates, and the length of the bitmap and takes a picture from that x,y and 'c ...Show All

• mkfl Mystery function in Game.Run using more CPU than Update+Render

  I implemented multi-light shadow maps in my XNA game engine and I am experiencing a pretty significant slowdown. I checked with PIX and I seem to be at a reasonable number of DrawPrim (under 50) and SetRenderTarget (single digit) calls per frame. The shadow map shader is based on the D3D9 sample. I had the Task Manager open and I spotted my game was only using about 60% CPU (I have only a single core processor). My profiler shows this: 48.92 % Game.Run... - 10384* ms - 0 calls 13.82 % function * - 2933 ms - 987 calls - class . function *( parameters ) 7.34 % Draw - 1557 ms - 329 calls - SharpX.Game.Draw(GameTime) 4.94 % Update - 1050 ms - 620 calls - SharpX.Test.TestGame.Update(GameTime) 1.71 % MouseSubClassFunc - 363 ms - 401 ca ...Show All

• Karl Erickson YawPitchRoll`

  There is no YawPitchRoll matrix in XNA..... Why The focus of XNA is on multiplatform development. XBox is obviously an important part of that, but we take PC very seriously too! That won't be slow at all, at least not any slower than if we'd included this in the framework. That's how you construct a yaw/pitch/roll matrix, so if it was in the library, we'd just be making three separate matrices and then multiplying them together internally! If you are concerned about performance, this sort of code can often be made more efficient using quaternions, which can represent any kind of rotation using just four floats (and also don't suffer from the same gymbal lock problems that axis rot ...Show All

• Mike Greenway Easiest way to create a laser effect for a board game conversion?

  Just as the subject says, I have a couple of projects in the works where I need a laser effect for board units. One thing that I'll need to do is have it reflect off of objects. If anyone have any suggestions/ideas I'd greatly appreciate it. Just found the How to: Draw Points, Lines, and Other 3D Primitives in the help. I'm not sure if I can get a cool effect like I'd like to have but it might do for now until I get a handle on shaders. Maybe have a look at the ParticleTrail class in the PsychoBreakout demo. Need to study it myself. Assuming you already know where you want to draw your lines and are just looking for suggestions as to how to draw them - you could draw the line segments usin ...Show All

• Cygon4 What is the best software for game dev with XNA?

  As the title states, what software will be good to have. I am going to download Visual C# Studio Express, but what else is good for stuff like graphics or sound.

• SMaia XNA 2D Collision Detection using Quadtrees

  I've seen a few posts on collision detection, and though I'd post an article on how to write a collision detection engine for your game. Take a look at: http://mbebenita.blogspot.com/ I'll follow it up with some source code as soon as I get a chance. Michael B. It's a great, relavent topic and I look forward to seeing more on this tutorial! Efficiently detecting collisions.... :D Ultrahead wrote: Ok, I understand that.

• domw001 Managed DirectX10 on XP64

  Hello, I am porting a C# app which uses DirectX from 32bit to 64bit. I downloaded the Aug 2006 SDK. I looked around and saw that in the folder: C:\WINDOWS\Microsoft.NET\DirectX for Managed Code There are many versions of the DirectX dlls, but there is only one version for x64, and that version is 2.0.0.0, which is DirectX10. I guess this is more of a request for a confirmation rather than a question. Is DirectX10 indeed the only version whose managed code dlls has been ported to 64 bit Or, put another way, if I'm going to use DirectX on Win64, does it have to be DirectX10 Thanks Michael Oneppo wrote: It's worth mentioning that we take .NET development scenarios very seriously and we are worki ...Show All

• Sobreira So basically "Cut & Paste" from Beta1 to Beta2?

  Not including the coding changes involving the content pipeline, to transfer my code from beta1 to beta2 is a simple matter of creating a new project and copying all the data over right Now if ultimately, I want to create a 360 game, I would have to wait until the final release, then "cut & paste" one more time to a new 360 project, is this correct Yes that is correct. When you make your 360 project you can either add all the files to the project, or do 'add link'. Then both projects point to the same source files. you can make 360 projects now, just cant run them or anything yet. The ZMan wrote: Yes that is correct.

• zdrae Integrating Joystick w/ DirectX9.0 and VB.net

  I had successfully integrated a joystick using VB6 and DirectX8.0 ( ) a few years ago.  I wanted to do the same thing with newer technology... I recently purchased VB.NETand a joystick thinking that the taks would be a cut and paste of old code with some minor modifications.  I found that I can't download DirectX 8.0, and now I must accept 9.0.  It seems as if every thing is skewed towards C# & C++ now regarding joysticks... My simple question:  If I download 9.0 SDK (Managed code) will I be able to 'enumerate' the device and read it using VB.NET Advanced question:  I noticed that 8.0 SDK method SetCooperativeLevel expected a windows handle that was type 'long', which is now 'int32' (or something similar) ...Show All

• Oscar99 XBox 360 hard drive question for MS staff - semi off topic

  With all the great new offerings out or coming soon for the 360: XBox Live Video Marketplace, XNA game creation, and the recently announced IPTV, the poor little 20GB hard drive's days look numbered. Is MS planning to release a larger hard drive for the 360 I'm pretty sure that many people (including myself) would be very interested in one. That sounds pretty realistic. I also wouldn't be surprised if they built an HD-DVD player into the next, "ultra" 360 model. The format war is still in full swing and Blue ray has the advantage of being built into all PS3 systems. It's the natural progression of the machine just as the PS2 was later slimlined. The model s ...Show All
