      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.

Layer and Frame?

8 posts in this topic

Hi,

   I am making a small game, where, now I want to implement layer and frame. Something like timeline. Each scene will consists of some layer and each layer will have some frames. Each frame will be used as a level and each layer will decide which entity will be visible. If a layer is invisible, all the entity belongs to that layer will be invisible.

   I just need some idea how do I implement them! As a class, struct or vectors etc. I only need idea, nothing else.

 

Thank you.

I'm not sure I understand what you mean. Could you try re-explaining it another way? Maybe do a very rough mockup in MS Paint to help me understand it better?

This doesn't sound like a Game Design question. I'm moving it elsewhere.

Sorry for not explaining clearly. Generaly a timeline looks like this -

I also want something like this, but it will not be visible graphically in my game. It will only work internally. What I wanted to do is, load the resources at the initialization and setup all the levels at the same time, frame by frame. Each frame will be a separate level. And during runtime, just change the frame to change the level. Each level will have some layers, which will decide the visibility of the entities. What I wanted to know is, how do I implement them, as a class, as a struct, as a vector or something else. A simple example will be, Flash actionScript 2. The levels are created frame by frame during initialization and nothing is freed/loaded during runtime.

I think you need to specify what exactly some of your concept keywords actually means. We can't help you if we don't understand your concept of:

  • Level
  • Frame
  • Layer

It is a 2d game. So basically what I am trying to do is, rather then making game states and clrearing/loading the game resources during runtime, I am thinking to load everything at the application start and set all levels frame by frame. Then when I have to change the level, I will just skip the frame. I have implemented the scene, resource loading etc, now I have to implement only the layer and frames. it is like -

Scene -- Layers -- Frames

If I hide one layer, every entity belongs to that layer will hide and remain invisible to all frames(levels).

 

Thank you for your reply.

You are over-thinking this. If for some reason you need to load everything at startup (highly unlikely actually but hey-ho) then design your architecture so that any given level or however you compartmentalise is stored in some kind of structure hierachy - e.g. a Level class, containing a list of Entity instances etc.

 

All the code then uses a reference to the current structure. You can load all the structures at startup and just change this reference when you want to switch levels.

 

All this hokum about layers and frames is entirely distracting from a far simpler question.
