      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

  1. Just wondering if someone would be able to help.   I am using slimdx january 2012 SDK and i am having some trouble using the .toxfile method.   The main problem is i cant find it. I am creating my mesh and everything fine, just need to send it to an xfile and can't find it in visual studio.   Thanks in advance.
  2. Just wondering if someone would be able to help me with a question that i have.   I am currently fiddling around with a mesh that i create at runtime.   It works when i don't use lighting, however every fourth position in the vertexbuffer is NaN. This doesn't seem to cause any issues in this case.   However, when i move to utilising lighting, i compute the normals and the vertexbuffer has seven positions for every vertex, the x,y,z of the position and the x,y,z, of the normal and then NaN in the seventh position.   However, when the mesh is rendered it is just garbage.   I am wondering if someone would be able to help with this, possibly explaining if i am doing something wrong?   Cheers using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using SlimDX; using SlimDX.Direct3D9; using SlimDX.Windows; using System.Runtime.InteropServices; using WindowsFormsControlLibrary1; namespace WindowsFormsApplication1 { public partial class PoleCreation : Form { public static RenderForm Window; // Window used for rendering. public static Device D3DDevice; // Direct3D device. public static VertexBuffer Vertices; // Vertex buffer object used to hold vertices. public static short[] index; public static IndexBuffer indices; public float[] vertexnormals; public Mesh mesh, normals; private Single rotX = 0, rotY = 0, initX = 0, initY = 0, finX = 0, finY = 0; private Boolean booMovingMouse = false; private Single WheelScroll = 0; public Single ModelAngle, Diameter, PoleHeight, Outer, Inner, x, y, z, Taper; public PoleCreation() { InitializeComponent(); } public void InitializeD3D() { vertexnormals = new float[2772]; // Create a new PresentParameters object and fill in the necessary fields.

  3. Hi Guys, Just wondering if someone would be able to help me out. I am trying to paint my directx in a picturebox or panel. I have managed to get it working by painting to the form with the protected override void onPaint function and using onPaintBackground to avoid flicker. However, i am trying to map this over to picturebox or panel however i can't find an onPaintBackground function to prevent flicker in the picturebox/panel. If there is any information someone would be able to provide to prevent this flicker, that would be great. The main reason i am trying to do this is so that i can put other controls in the form and painting the whole form doesn't allow use of the controls at runtime. Thanks
  4. Nevermind, I'm good. Turns out that refreshing the matrices every draw doesn't quite work appropriately.
  5. Anyone out there help me out? I believe that it has something to do with the speed at which the device clears the screen before painting the new one. If i put a breakpoint on the this.invalidate line and then hold f5 to just continue the program it works perfectly. Looking at msdn and a few other things, the invalidate method has to wait for the messages or something to stop or you should make the messages or something stop, i personally have no idea, so i am hoping someone can help me. Once it get this problem solved i should be good. Cheers guys
  6. Hi Guys, Just wondering if someone would be able to shed some light on an issue i am having. I am drawing a simply triangle and getting it to rotate around its axis. However, when i re paint the screen it flashes as it repaints. I have attached the code if anyone could shed some light on this problem.

  7. Hossainiir, not sure what you mean by PIX? could you elaborate? thanks adt7, but not sure what i should be doing for drawing. i uncommented the drawprimitives section and it still just shows a blank screen. Is there something i am missing?
  8. Hi Guys, Just wondering if someone out there would be able to help me with what i thought would be an extremely simple thing. I have been searching the web trying to find some example code on how to draw a simple 3d cube. I found some [url="http://www.vbforums.com/showthread.php?625045-draw-3D-cube-Direct3D"]here[/url], which i have translated from vb to c# and from managed directx to slimdx. However, the cube does not want to draw and i am at a wits end as to why. The background is fine but just cant seem to get the cube to show up.

  11. Hi Guys, Just wondering if anyone would be able to help me. I seem to be having an issue with computing normals of a mesh using slimdx. I am getting the D3DERR_INVALIDCALL: Invalid call (-2005530516) error whenever i try to compute the normal of a mesh. My code is probably not the best, however for a first attempt i am doing what i can. I have attached it to help with the troubleshooting. Thanks in advance for any help.
