      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.

Passing TexCoords to the shader, always get grey textures - Solved

3 posts in this topic

EDIT:
I erased everything because i realized my texcoords are just fine, but my texture is always rendering grey.

I started passing in texcoords manually to the sampler, and it was giving me parts of the texture like it should... I think.

[code]
/*HLSL*/
// My list of texcoords, they're getting passed correctly i've debugged this
float2 gTexCoord[4];

struct InVertex
{
float3 position : POSITION0;
int nIndex : TEXCOORD0;
};

struct OutVertex
{
float4 position : POSITION0;
float2 texCoord : TEXCOORD0;
};

OutVertex VertexShader(InVertex input)
{
OutVertex output;

output.position = float4(input.position,1);

// Setting the texcoord for this vert.
output.texCoord = gTexCoord[input.nIndex];

return output;
}
float4 PixelShader(float2 texCoord : TEXCOORD0) : COLOR0
{
return tex2D(gSampler,texCoord);
}
[/code]

[code]
// The vertex declaration
D3DVERTEXELEMENT9 decl[] =
{
{ 0,0,D3DDECLTYPE_FLOAT3,D3DDECLMETHOD_DEFAULT,D3DDECLUSAGE_POSITION,0 },
{ 0,12,D3DDECLTYPE_FLOAT1,D3DDECLMETHOD_DEFAULT,D3DDECLUSAGE_TEXCOORD,0 },
D3DDECL_END()
};
[/code]

I'm going to try to test the index, to see if it's getting correct values

EDIT: SOLVED

It was indeed the vertex declaration, i was sending it a D3DDECLTYPE_FLOAT1, i changed it to a D3DDECLTYPE_SHORT2 and it worked just fine. I can see why it works, but i feel like it still should work with FLOAT1 Edited by Muzzy A

Once again, maybe something to do with D3D9 on VS 2012?

It would not be a problem in my opinion.

Could you show the vertex declaration, please?

Why? You have it defined as an integer in your vertex shader input.
