      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.

Enhancing graphics

6 posts in this topic

My game currently looks like this: http://puu.sh/2PTkA.jpg

I made it in Java using lwjgl. As you can see it doesn't really look nice. So my question is, does anyone have tips for enhancing it? (I kinda know glsl)

Spot on, the grainyness. 

 

Artistically speaking, what looks pretty? Clever variation.

I think you could improve things by adding some lightsources (even if "baked", such as with lightmaps) and use subtle vertex-coloring to add some color to corners and bits of walls.

If you have normal-mapping going on, it's a good idea to add a clearly recognizable lightsource so we visually understand why the walls are lit like that. It's consistent.

Download Blender and fix your gun. Ewww...

 

Reduce the graininess with mip-mapping and linear filtering

A bit more colour variation in the textures would look great. I think the normal scale has turned out alright in this case, whether that's by luck or coincidence. You could do with a little ambient light - a light in that enclosed space wouldn't leave the away-facing parts of the wall pitch black.

What the former two said is really true for you. I think textures are so important for graphics,it will help you to catch people's eyes at their first sights.So,do this part firstly.

Hi,

 

Textures from actual photographs (in digital file format such as Bitmap and JPEG) are typically the best to use, sometimes looking exactly like real life surfaces of objects.  Shaders and in particular procedural mapping of textures and shaders have come a long way but will likely never have the consistency of the good image texture mapping by an artist one at a time.  Humans can detect flaws and inferior appearance, but procedural generation of surfaces will never notice the things which the human mind can.  The disadvantage of "live" textures would be that creating many objects or much terrain is much more expensive in labor, time, and cost because each texture must be applied manualy if you want the very best.

 

On the other hand, I have worked with artists using procedurally generated surfaces which look realistic.  Development of these procedures can be time consuming of themselves but worth it for large scenes with many objects or much terrain.  Many games use both procedural and manual made surfaces, which allows the best technique for each need.

 

Get used to coding for both procedural and image applications.

You mentioned that you are using a shader for this.  To me it looks like maybe there is a conditional switch causing a sharp cutoff for the specular highlights. 

 

Look for a conditional like this in the fragment shader.  Get rid of the 'if' statement if it's there, the highlights will look better and the shader will run faster as well. 

 

 

if(diffuse > 0.5)

{

specular = dot(halfVec, shininess);

}

 

 

Also, turn down shininess, it will spread the highlight out a bit so it spreads out around bumps a bit more,  it'll flicker less.

 

If you are using normal maps, blur them a bit in a 2D image editor and this will reduce the harsh flickering even more.
