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.

Meshes with multiple parts

2 posts in this topic

I am having a problem with trying to upload game asset. I am making geometry in 3ds Max for a game I am working on. I want to make a character with multiple parts but i don't want to have to upload ever single part individually. I want to bring in say a body with shoes as one mesh. is this even possible? Another example, lets say i want to create a robot. Do i have to bring in every little part that i articulated on the robot as individual meshes or is it possible to bring all parts in as one mesh? I am having problems here because i want to make robots with tank wheels but do i have to load the wheels individually for each bot or can i just bring the all in as one mesh. I am not trying to animate the wheels turning yet or anything. any ideas would be awesome. thanks guys

What do you mean by upload?

If you're talking about uploading to the GPU, via some graphics API, then you should be able to simply export any collection of objects as a single mesh (your modeling software probably provides the utilities to join multiple meshes like that).

Though I don't use Max much, I do know that the game doesn't generally recognize the individual parts the way we see them. The modeller has to save or export the model in a certain file format which the game uses and place that file containing the model into a folder, often in a class. Is this what you mean by "upload game asset"? The game will see one model even if the parts are individual or even separated. It is possible to make a model which has all the parts not even touching but the game will see it as one model if saved into a single model folder.

It is also possible to create a whole character model from one primative (polyhedron). This is done through extrusions and other sculpt tools. I don't use Max for sculpting, but there are some great tutorials out there for it.( I use Wings3D or Blender for sculpting) However, since you probably want to animate certain parts such as the legs, then those will have to be made as individual parts so they will move.

So, create the model any way that you want and save it all together in the same model file format that your game uses. If the graphics engine is coded right, then all the parts should appear in the game exactly in the position that you created them in Max - character with limbs, head, shoes, and so on.

A performance tip for the game would be to use as few material or image files as possible for the model: The fewer the files in the model folder, then generally the better the performance.[img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img]
