      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.

Calling rasterizer from effect file

4 posts in this topic

Hi, i have following problem. To set the rastersizer state through c++ code works but when i try to set the rasterizer with an effect file i get the error: Assigment FillMode: Only literal right-hand side values are allowed in the state blocks Effects performance mode
and then the whole application crashes.

The .fx file (source from introduction to directx 10):

[source lang="cpp"]cbuffer cbPerObject
{
float4x4 gWVP;
};

cbuffer cbTime
{
float gTime;
};

void VS(float3 iPosL: POSITION, float4 iColor: COLOR, out float4 oPosH: SV_POSITION, out float4 oColor: COLOR)
{
oPosH = mul(float4(iPosL, 1.0f), gWVP);
oColor = iColor;
}

float4 PS(float4 posH: SV_POSITION, float4 color: COLOR)
: SV_Target
{
return color;
}


RasterizerState Wireframe
{
FillMode = Wireframe;
CullMode = Back;
FrontCounterClockwise = false;
};

technique10 ColorTech
{
pass P0
{
SetVertexShader(CompileShader(vs_4_0, VS()));
SetGeometryShader(NULL);
SetPixelShader(CompileShader(ps_4_0, PS()));
SetRasterizerState(Wireframe);
}
}
[/source]

and now im not sure what to do in the c++ code. is it necessary to call something in the effect pass or should it already work? sorry if the question is pretty dumb but im new to directx and hlsl

[source lang="cpp"]D3D10_TECHNIQUE_DESC techDesc;
mTech->GetDesc(&techDesc);
for(UINT p = 0; p < techDesc.Passes; ++p)
{
mTech->GetPassByIndex(p)->Apply(0);
//do i need to set the rasterizer here somwhow? (when i do it through the fx file) ?
mBox.draw();
}[/source]

regards helgon

You just defined "Wireframe" as your rasterizer state structure, so you can't really use "Wireframe" as your fill mode anymore, can you see why? You don't want to call it that, try calling it "wireframeRasterizer" or somesuch. [s]But IIRC, the error is because "Wireframe" isn't a valid constant. It's actually WIREFRAME. Same for culling mode which is BACK. But I could be incorrect... been a long time since I D3D'ed.[/s] Edited by Bacterius

My bet would also be that the problem is in naming your RasterizerState Wireframe, it then probably thinks that you want to use this rasterizerstate as fillmode? As Bacterius said, try to rename the RasterizerState to something else.
But where I don't agree with Bacterius (and why I'm writing this post) is the second part - Wireframe is perfectly valid as a FillMode, upper and lower case don't matter here. Edited by Tom KQT

you guys are officially awesome, thanks for the quick answer - i just had to rename the RasterizerState - strange that the example from the book was given that way
