      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.

  1. to visualize it for your eyes, you might need to map your image to sRGB.
  2. The higher your resolution, the higher the spatial frequency, hence the perceived aliasing should increase. Tho, the downsampling on PS4 Pro to 1080p is really nice for AA. Digital Foundry dissects games in this respect and some games really give you all the options to choose from, e.g. recently: https://www.youtube.com/watch?v=rDKmJB629-0
  3. if you disable depth testing and set the transparency to be additive, it should look consistent (not correct, but always consistent). that way you'd know it's just the transparency sorting.
  4.   Are you 100% sure you have a problem with the shading? Isn't it maybe some transparency sorting? "bad" is not a good explanation for a problem ;). Post maybe a screenshot of the issue.
  5. if it depends on a coherent flag (e.g. a constant for the whole draw call), you can use dynamic branching nowadays, there won't be a big performance impact, might be even faster as you don't need to switch shaders that many times.
  6. The best limitation is competition. Make the market-share a key in the demand for the product. An example from real life is e.g. Windows Phone or Black Berry, they have a low share and nobody wants these, because nobody has these. Similar e.g. if you just look at the Android market. There might be phones as good or better than Samsung's S7 ot S8 (for half the price), but it's the most wanted one. And if you ask marketing people, they'll tell you that "mind share" of users is what they all aim for. On the lower end, you need to invest more than the revenue, to get mind share. On the higher end, it's self propelling. Hence, make the player realize, one big product gonna have more demand, will lead to higher prices, bigger margins, longer lasting market success. Allow them in some way to merge products, maybe at a high cost (e.g 100%+100%==150%), but eventually worth it. This would usually also lead to fusion or buying of competing companies.
  7. That's a wise choice of a team name :)
  8. haven't tested it, just my brain fart: template< typename TYPE > int GetLod( const Tuple3< TYPE >& _a, const Tuple3< TYPE >& _b ) { const Tuple3< TYPE > ddx = a-b; return LeadingBit(dot(ddx,ddx)); }the idea is: usually, you would call length(ddx), and then increase the lod with every doubling of the distance. (assuming LOD0 is highest quality). taking the leading bit of the squared distance combines both, but runs with integer only. for "LeadingBit" you could exploit that intrinsic: https://msdn.microsoft.com/en-us/library/bb384809.aspx
  9. is the problem the shadow mapping or the rendering of the shadow map? Have you made a capture of your rendering and checked your shadow map? if you make a capture, check the vertexbuffer before and after the vertex shader (for shadowmap rendering). this might already show the issue. (you can use e.g. NSight)
  10. A simple trick: offset the sampling position by the normal of the surface that receives the shadow. kind of float bias=0.001; float4 positionInLightProjection = mul(float4(thisWorldPosition+thisWorldNormal*bias,1.0f),lightProjection(ilight));
  11. I'd go for 2. it keeps everything unified. the "virtual texture" on disc is nothing more than any other texture, beside being freaking huge, but that's just numbers. you don't really care at the high level. (you might care for optimization, e.g. tiling)   for the first implementation, don't go banana with sophisticated uv-space management (bsp etc.), in theory the uv space is unlimited. you will run into some issues at some point eventually, but you might solve that in a simpler way than writing managers to solve issues you "might run into" ;)
  12. I'd give the player abilities that don't all work together, hence to be "prepared" would mean to have the right ability/mode selected. e.g. in yakuza you can choose different fighting styles. Add on top, that you only can switch styles when you're at full health, hence even a light encounter that surprises you would force you to fight in a sub-optimal mode. (you'd be dead, without admitting it).  Instead of "healthy" you could also use "fitness" instead. Hence running through the map (unprepared for fights) would render you exhausted and you wouldn't be able to switch into a fight mode. To be always prepared, you'd need to always walk slowly.
  13. I guess you decompress the position (i11:i11:i10 -> f32:f32:f32) and then add the offset of the chunk, as float. This will/would result in float precision issues. Try to use integer offsets, therefor you decompress i11:i11:i10 to i32:i32:i32, add the integer offset and just now convert to f32:f32:f32.
  14. I like the basic idea. (As I also like the difficulty and challenge of Dark Souls, yet I don't like the basic combat mechanics, it's somehow not my taste).   Wouldn't a Dark Souls as shooter boil down to pure boss fights? That is somehow appealing :). To start small, it could be an shump imo. The basic idea wouldn't change much between 3rd person 3d and top down 2d.
  15. The explained solutions were mostly for texture atlases. Mega textures work slightly different. 1. There is no hardware mip mapping, this would break quite a bit of the tech. It actually avoids these issues by handling mip filtering by the pixel shader. 2. The tiles always ( on every mip level) work the same and the border size depends solely on the filtering you use (bilinear, anisotropic,..), 1 pixel for bilinear. 3. The Mips don't include the border, the mips are only generated based on the border-less base texture. Then you divide each level into equally sized tiles, e.g. 126x126 and add the 1 pixel border. 4. While the border might sound problematic, the alternative would be to always load the surrounding 8 tiles into the texture as well, to filter properly cross border, that would be 9x the memory usage. 5. please don't mix atlas textures and mega textures. Atlas is the idea of fitting a lot of textures into one. Mega texture is actually the opposite, to have one big textures (no borders, a triangle could map it completely). The tiling is only a solution to low level memory organization. On modern hardware, you could use Partially Resident Textures (PRT), that can solve a lot of the Mega texture issues. Texture Atlases would still have bleeding issues etc.
