I have used A* before, but I would like to learn how to setup my own system using it so that I can make my own alterations to it. I would like to explore some of the AI methods and techniques I have discovered in my AI class and use that to alter a foundational pathfinding system built with A* to come up with some interesting ways to influence pathfinding in games. I would eventually like to have the AI "learn" from the player's patterns in some way to influenece their overall "A* type" pathfinding to find different ways to approach or avoid the player.

Online Multiplayer Networking Solution Tutorial Using Unity and Mirror - Tutorial by: Jason Weimann

February 2, 2021 Networking Online Multiplayer Unity & Mirror Title: Let's build a 4-Player Networked Game LIVE - Online Shooter (with Mirror & Unity) By: Jason Weimann Youtube - Tutorial Description: Intro to using Mirror for networking online multiplayer play in Unity development. Introduction This tutorial has Jason Weimann implementing online network play into a basic Unity twin-stick shooting game. They use Mirror, which is a Unity asset used for simplifying the online network synchronization process. This is a live implementation where they work through many errors transferring a game from simply working locally to working with a host/client relationship. Mirror Mirror - Home Page Mirror is "a high level Networking API for Unity, supporting different low level Transports" (from Mirror themselves). It is a clean solution for implementing a quick and simple online networking option for Unity projects. The core components breakd

Houdini Assignment - Fuse and Group

April 8, 2019 Houdini Assignment Fuse and Group I worked on a Houdini class assignment to make a basic model and decided to try and create the bulb on the back of a Bulbasaur, a Pokemon that is half plant and half dinosaur. I figured I could use a lot of the basics we learned in class to get me pretty far, while also needing to cover a few new things to get it exactly how I wanted it. In class, we created a basic hot air balloon. This consisted of tracing a curve over a background reference image of a hot air balloon, creating a section of the balloon from this original curve, then replicating that section as many times as needed to fully encompass the full balloon. These were a lot of principles I used for creating my bulb. The biggest hurdle I needed to overcome was that that top of each of my sections would all need to connect at a single point, so I would need some additional nodes after simply creating a "left" and "right" variation of my addit

Exporting FBX from Houdini with Color

April 17, 2019 Exporting From Houdini FBX and Color Information Exporting the Model Using my balloon Houdini example from class, I was able to export the geometry using the Educational version (the Apprentice version does not allow exporting FBX, but you could export an OBJ for my purposes possibly). This was very straight forward, as you can just use File -> Export -> FBX in Houdini. Since I was doing this for a class to use in a Snapchat filter (using LensStudio), I wanted to reduce the poly count a lot. I opened the FBX in Maya and used a basic Reduce to reduce the poly count a lot before exporting that for use in LensStudio. While this was good enough to export the geometry, I could not get any of the color information to come with it. I originally exported out an OBJ and had the same issue, so I exported FBX in hopes it would keep the color information somehow, but this was not the case. Exporting the Color Information My first thought to get the color
