Storing stuff in Unity3d

The last days, or weeks, maybe months, I have been fighting with the problem of storing several game element definitions, like NPCs, their inventorys, items, skills and abilities.

Lets say you want to have an NPC named Frolo the Habbat at point X. In Unity3d editor you can place the mesh, adjust it, etc, but, how do you specify that Frolo has a Big Stick of quality 3, his attributes are 4,5,4,6 (whatever that means), and has a Magic skill level 5? My first approach was to use XML. When you have a hammer, all problems will look like nails to you, and in this case, XML is the hammer I have been using in all my previous iterations of this project. It is flexible enough to let you put any number of different stuff inside. The drawback is that you cant edit it inside Unity3d editor.

The Unity3d solution is to use ScriptableObject and asset files. An asset file can store the definition of an ScriptableObject, and its properties can be edited in the editor inspector. The asset files are good to represent unique things: an item, an NPC. But I havent found a way to use it to represent a generic skill that I can attach to the NPC skill list and then set its level for that specific NPC.

Probably Im going to stick to XML for a while.

Isometric camera with Godot

Took some effort and some of my sleep hours, but at last, I made it. Here is my first videotutorial: implementing an isometric camera in 3D, with Godot. Useful if you want to emulate the look of old classics like Fallout 2, but with some extra features. Considering that my voice is not so nice, and my english pronounciation is even worse, I also added texts to help you underestand what Im saying. You will also notice some background noise, but cant do anything to solve that. Any suggestion is welcome. Expect another tutorial soon.... or sor tof. This time, will be about my AI system.

Unity3d isometric camera tutorial

I had pending this since a month ago, so Im forcing myself to post it today. The goal is to provide a fully functional isometric like system that you can use with few or none modifications in your own game. So, lets get started. Start Unity3d and in your scene, add an empty GameObject, we will call it target . Create a camera object and drag it to target to make it child. The result looks like this: Now select Camera and set the values to this: For a true isometric like feeling, ortho projection is essential. You could use perspective, but it is not the same. Play with Size to suit your needs (we will be using this later, when implementing zoom). Now, lets create an script named CameraController, or whatever, and drag it to target GameObject. Lets implement scrolling, the easier part: go to Update() and add the following code: if (Input.GetKeyDown(KeyCode.W)) {             dir = UP;         } e...

Tutorial: building a modular character

Building character models with body parts have been an obsession for me in the last weeks. I have googled, asked, googled, and asked again, played with Unity3d editor, tested code, and so on. You can see the result of my work in the previous post . First of all, I have to say that what I achieved is mostly derived from this thread and the sample posted there. My code is a copy&paste of that sample. Also, you can find a more extense solution in this Gamedev.net forum thread . First, lets start with the model, which obviously, is divided in the required sections. Lets say we have head, torso and legs. Each part must be exported to a separate fbx file, but it must include the skeleton. Then, export the skeleton without geometry to another fbx. Im going to assume that you want to instantiate all components, and even player, at runtime, from a  C# script (no Unity editor involved, except for creating prefab an position marker), so, we will place the sections, the skeleton and ...
