      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.

DX11
Modern directx and effects framework

4 posts in this topic

Hi. I'm reading on msdn that effects framework for dx11 is created for easy porting of an old projects. Does that means that if I create a new project from scratch for win8 I shouldn't use it?

Thank you. So, it's basically a wrapper around api states change, constants and buffer settins, right? What's the problem to, say, render all opaque objects, next change manually (via dx calls) necessary data/states and render particles, next render transparent objects? I have come from Adobe Flash 3d world, where we don't have frameworks like this, write shaders with some sort of assembler, and just have api calls (althought very limited). And I see many benefits of such manual coding.

To be honest, I'm confused a bit - I have a couple of dx 11 books, I'm reading online tutorials and it all seems good and fresh. But due to recent changes in windows (i.e. remove of d3dx, shaders compilation out of the box etc.) all examples simply don't work and need refactoring. And it seems that only examples that can run without any changes with vs 2013 is a couple of templates on msdn code base for windows store. Can you advise actual resources? May be groups or chats?}

About D3DX: yes D3DX was (finally!) deprecated, however Chuck Walbourn made a set of project that could be very helpful to replace it: you can read more about here http://blogs.msdn.com/b/chuckw/archive/2013/08/21/living-without-d3dx.aspx

 

Here are the four projects (... and maybe they will turn five in Summer, with a new library replacing the old D3DXMesh)

Yes, it's just a "smart wrapper" and yes, you can completely ignore it and make your own system (or do everything manually all the time if you want).

I know the Effect Framework only from DX9 and I have no idea whether it changed significantly in DX10/11, but in DX9 it was quite a good system for people learning the programmable pipeline, because it made it everything very straightforward and simple. But as you started to understand better how it everything works, you usually realised that the Effect Framework may not be really optimal if you try to do some optimizations of device calls and the whole rendering process - because you really don't know what's going on under the hood with its automatic state changes, texture setting, samplers, CPU pre-shaders etc.

      Hi Guys,
      I am revisiting an old DX11 framework I was creating a while back and am scratching my head with a small issue.
      I am trying to set the pixel shader resources and am getting the following error on every loop.
      As you can see in the below code, I am clearing out the shader resources as per the documentation. (Even going overboard and doing it both sides of the main PSSet call). But I just can't get rid of the error. Which results in the render target not being drawn.
      ID3D11ShaderResourceView* srv = { 0 }; d3dContext->PSSetShaderResources(0, 1, &srv); for (std::vector<RenderTarget>::iterator it = rtVector.begin(); it != rtVector.end(); ++it) { if (it->szName == name) { //std::cout << it->srv <<"\r\n"; d3dContext->PSSetShaderResources(0, 1, &it->srv); break; } } d3dContext->PSSetShaderResources(0, 1, &srv);  
      I am storing the RT's in a vector and setting them by name. I have tested the it->srv and am retrieving a valid pointer.
      At this stage I am out of ideas.
      Any help would be greatly appreciated

      hi, guys, how to understand the math used in CDXUTDirectionWidget ::UpdateLightDir 
      the  following code snippet is taken from MS DXTU source code
       
        D3DXMATRIX mInvView;
          D3DXMatrixInverse( &mInvView, NULL, &m_mView );
          mInvView._41 = mInvView._42 = mInvView._43 = 0;
          D3DXMATRIX mLastRotInv;
          D3DXMatrixInverse( &mLastRotInv, NULL, &m_mRotSnapshot );
          D3DXMATRIX mRot = *m_ArcBall.GetRotationMatrix();
          m_mRotSnapshot = mRot;
          // Accumulate the delta of the arcball's rotation in view space.
          // Note that per-frame delta rotations could be problematic over long periods of time.
          m_mRot *= m_mView * mLastRotInv * mRot * mInvView;
          // Since we're accumulating delta rotations, we need to orthonormalize 
          // the matrix to prevent eventual matrix skew
          D3DXVECTOR3* pXBasis = ( D3DXVECTOR3* )&m_mRot._11;
          D3DXVECTOR3* pYBasis = ( D3DXVECTOR3* )&m_mRot._21;
          D3DXVECTOR3* pZBasis = ( D3DXVECTOR3* )&m_mRot._31;
          D3DXVec3Normalize( pXBasis, pXBasis );
          D3DXVec3Cross( pYBasis, pZBasis, pXBasis );
          D3DXVec3Normalize( pYBasis, pYBasis );
          D3DXVec3Cross( pZBasis, pXBasis, pYBasis );

      Hi,
      I have a surface mesh and I want to use a cone to cut a hole on the surface mesh.
      Anybody know a fast method to calculate the intersected boundary of these two geometries?
       
      Thanks.

      Hi, I tried searching for this but either I failed or couldn't find anything. I know there's D11/D12 interop and there are extensions for GL/D11 (though not very efficient). I was wondering if there's any Vulkan/D11 or Vulkan/D12 interop?
      Thanks!

      Hi Guys,
      I am just wondering if it is possible to acquire the address of the backbuffer if an API (based on DX11) only exposes the 'device' and 'context' pointers?
      Any advice would be greatly appreciated
