animate-3d-models-with-mixamo

How to Animate a MagicaVoxel 3D Model using Mixamo. Import the model and animation data into Unity and play the character with joystick or keyboard input.

create-bones-on-transparent-2D-image

Animate 2D images in Unity with the 2d Animation package. Here I'll use Unity 2021.1 and the sprite editor to create bones on a picture of the pink panther. The sprite editor will also add geometry (mesh outline of the 2D image) and weight (effect of each bone on the nearby geometry). The geometry and the weight have automatic features. After the bones are added to the sprite asset, drag and drop the sprite into the scene. Add a 2D Animation, Sprite Skin component and click the button create bones, so the component can detect all the bones you added in the sprite editor. Then when you move the bones the sprite beneath it moves. You can now animate it.

how-todo-marching-cubes

Haven't made a video in a while. That's because this marching cubes algorithm took me awhile to unravel. Most of the work was in the 256 cube configurations and the isofaces it takes to build them. I figured them all out myself (even though there were probably daat available on internet somewhere). Oh well, learn the hard way, and I'll never forget. In this video I'll go over how the marching cube algorithm works, how to use it, how to figure out the cube configurations. You'll see it animated in action. There is a cube configurator scene that helps you see what each cube configuration looks like. the MarchingCube.cs file is reusable so you don't have to write it everytime you start a new game project.

inspector-dropdown-editorGUIlayout.popup-

How do you add a dropdown to the Unity Inspector window for your script? You could use enum public variable type. But you can also use an array like I do in this tutorial here. I use a string array and a List collection. These are helpful if you don;t know what the contents of your array will be.

load-external-mp3-with-script-from-anywhere

Imagine making an audio player in Unity. How do you load a file from anywhere on the harddrive in Unity? I found a way to load a WAV file from anywhere on the HardDrive using WWW, but then I couldn't load an Mp3 file. I didn't give up I found that I could use NAudio.dll library to convert an MP3 to WAV in memory and then use the WWW to load the MP3 file from an external location in Unity. Hopefully WWW (which is deprecated) sticks around a while longer... or is replaced with something better.

marching-cubes-in-a-game

So know that I know the marching cubes algorithm, how can I implement it in a game of some type. One way is like in a minecraftee type of way. Modify the terrain around me in real time during game play... So that's what I did here in this tutorial video.

procedural-punch-to-target

HOw would you like to know how to animate a character to always punch toward any target in a scene? How to pick up any object they can reach? You dont want to use a canned animation because the scene placement maybe off a little. A solution is to mix the canned animation with a procedural one. Mic the canned animation with an Implementation of real-time inverse kinematics in Unity using the animation rigging package. YouTube

omarvision/setup-mlagents-artificial-intelligence-python

MLAgents is a library so you can do Machine Learning (Artificial Intelligence) in Unity. MLAgents is written in python. Setting it up to run on your windows computer requires some steps. You run the Python MLAgents library while you're Unity project runs to train a neural network file for the gameobject you are trying to make machine learning for. The Python MLAgents package runs in a python environment and listens on a port to the unity game running. It also controls the unity game running to put it through training loops. Anyway this video just goes over setting up the MLAgent library on your computer
