Pluggable AI

This weekend I spent some time revisiting the Unity Pluggable AI videotutorials, which illustrates the use of ScriptableObjects to build an AI system. This work is based on a conference by one Obsidian developer in some GDC (can't remember if was this year or the previous one).

My opinions on ScriptableObjects are still... vague, to say something. I'm trying to define if they are an essential tool or something that can be replaced by XML/JSON and one day I think they are the best and the next I think that I have to throw it to the recycle bin and go back to use XML. The opinions I have read on forums doesn't help me to decide.

But, how good is pluggable AI compared with my first approach to AI, based on coroutines? Well, it is much more modular, in first place. Not clearer, at least, not yet, because I'm still working to understand the basics. Maybe I can even get something good from this.

Right now I am in the stage of improving the code and integrating it into a sort of mini-demo project, a test bed for ideas. Thanks to the rain this morning I came late to office, and used that time to setup the basic patrol state/action, nothing fancy, but a first step towards adding more complex chains of states. Lets see whats the result.

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...

Testing animation retargeting in Godot 4

 We have finished the project and it is time tostart a new one. This time, I have convinced the team to work on a combat  prototype and try Godot 4. After a month, Im quite pleased with the progress. Specially, we have applied animation retargeting, which is a new feature in Godot 4. In previous project, our main artist devised a clever way to reuse animations, but now we have a native solution. Our first attemp didnt worked, but I found that remapping the armature starting by the feet solved the problem. Weird, isnt it? By the way, you can see the prototype here . WE are keeping it public to let people learn from our mistakes. And, if you need some animation retargeting tutorial, this is the guide we used:
