Fixing old mistakes

This weekend I made another offensive to my item equip code. It depends on the mesh assembly code, which deals with building a model from several meshes, if they share the same skeleton. To be equipped, the  item must have the same skeleton too, of course, and the widely (and only) documented method is to copy the bone info from the base skeleton to the other meshes. Simple items like weapons does not need this, as they can be attached to a bone and that's all.

But my first approach had major flaws. It required a list of prefabs that were assembled into a a model and then to a list of GameObjects, the NPCs were not visible in the map, and just recently found that destroying the switched part left me without the original part to restore it when the item was removed.

So, I sat and put my brain in afterburner mode. It didn't worked... until yesterday, when at last I figured out how to get rid of the lists of original prefabs, the resulting GameObjects, etc, and put that in a single list plus one for equipped items. NPCs and player model require different initialization, but that is a lesser problem that I will address tonight. Before, I destroyed the switched part: if I equipped an armor, the torso was removed. That was totally unnecessary, as I can just disable the torso part and show the armor, and reactivate it when the armor is removed.  Quite obvious, now, and I was plain fool to not to realize that from the beginning.

Now I have to make a short halt and spend some time with Unreal Engine. I promise this time I will put a serious effort on it.

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...

Vulkan and open source engines

It is weird, but even when Vulkan has embraced the open source philosophy (open drivers, tools, etc), Im not seeing too much enthusiasm to adopt it in open source game engines. I have been following mostly Godot and Urho3D, yet Ogre3D and Irrlicht doesnt seems to be rushing to implement the new renderers. It is worth to mention that Godot promissed they would delay the long needed refactoring of its 3D renderer until Vulkan release, but now they say they wont be using it, favoring GL ES 3 instead. The other engines seems to be dealing with lack of man power (Urho3D leader left the work on hands of community, as he is not working on Vulkan renderer right now) and base code designed for older APIs, specifically, DirectX 9. Lot of work is required to adapt this code base, not only for Vulkan, but for DirectX 12 too. Well, nobody said that developing a game engine was easy. The advantages of Vulkan have been widely detailed. From engine point of view, it would centralize all renderers...
