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.

Strange GLSL issue

1 post in this topic

My program works on my laptop but it doesn't work on my friends laptop.

The graphics card which I use is:

GeForce 8600M GT/PCI/SSE2 from NVIDIA Corporation

The graphics card which he uses is:

ATI Mobility Radeon HD 3650 from ATI Technologies

The error outputted to stdout is rather random but it's always along the lines of this:

Shader Failed to Compile Vertex shader failed to compile with the following errors:

ERROR: 0:8: error(#132) Syntax error: 'E968' parse error
ERROR: error(#273) 1 compilation errors. No code generated

Shader Failed to Compile Fragment shader failed to compile with the following errors: ERROR: 0:7: error(#132) Syntax error: 'ix' parse error ERROR: error(#273) 1 compilation errors. No code generated

I tried several different ways of doing the fragment shader including specifying different versions of glsl useing #version and it seems that no matter what I get to work on mine it doesn't work on his.

The vertex shader seems to work on his though because it's outputting the polygons just they are all white.

Right now the fragment shader is only this and it still doesn't work on his laptop but it works on mine:

uniform vec4 color;

void main()
gl_FragColor = color;

Also, it seems to be very picky on my side on whether it will compile or not...

like if I were to have something like:

gl_Position = gl_ModelViewProjectionMatrix*gl_Vertex;

then it would work but if I had

gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;

then it won't work. The spaces beside the '*' mess it up.

Is this really normal? Edited by Homunculi

I see this problem come up often on these forums. Perhaps you aren't NULL terminating the string you send to GL or you aren't reading in the shader text file properly.
