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.

A few questions (animating and C++)

1 post in this topic

Ok to start out I'm new to programming and this site. And I have been planning to start a building a game using Irrlicht. But before I get to that I have a question about rigging, when you are programming for multiple meshes would you need to support the animation of the rig for each model or is there a simpler way? Or when making the meshes for say a human and a dragon, would the mesh need to be the same and just manipulate the rig to support the entire mesh? And the last for now, is it better to script the storyline hardcode it into the cpp?
Thanks again for any responses, as I said I am new to game programming and had some questions that I could not find answers for.

There's no such thing as "support the animation of the rig for each model".
All the rigs are the same "numerically speaking", just as all things having 3 distinct points make up a triangle.
I suggest to separate the concept of mesh and animation. Some systems pack the rigs with the mesh (which makes sense) while others allow to pair them independently (I don't think this buys anything).
In general we have this [i]mesh+animation data[/i] pair where the animation data evolves... typically with time.
So enter [i]mesh instances[/i]. The evolution of the mesh data changes across all the meshes even when they are the same.

1) a mesh M1 (model MDL) with rig R generated at frame F.
2) a mesh M2 (model MDL) with rig R generated at frame F+20.

It is clear that those two meshes have the same base model and the same base rig, yet they are different istances and must be managed correctly.
So in short: you have to bite the bullet and [b]support a different [i]pose [/i]for each [i]model instance[/i][/b]. This does not mean they also need a different rig: the rig is the same, just in a different state (rig != pose).

I have extreme difficulty in imagining a rig which would animate correctly both a human and a dragon.
There's no requirement for a rig to be unique to each mesh but this implies meshes will have to be similar. A human rig could probably be shared with a alien humanoid or perhaps a chimpanzee. A horse? I don't think so.

You are suggested to split storyline questions in a different topic. In my opinion however hardcoded storyline is hard to write and typically even harder to manage and keep in shape. Most games are scripted, where the most basic form of storyline scripting is the level succession. If level progression is non-linear, this is somewhat more complicated.
