Damage, Leveling Up and Death

Encapsulation and Item Pickups

They cover encapsulation again just to explain why they use different access modifiers for different fields and methods within the scriptable objects they are creating to deal with the character's stats and items.

Stat Increasers

They covered methods that increased the stats of the character. They were pretty basic, where they added values to specific stats and checked if the value would go over the max value to set it directly to max if that was the case.

Stat Reducers

This was very similar to Stat Increasers methods, but with subtraction and checked if the value would go below 0. This made me realize there's a better way to do this where you check if a value would go below 0 BEFORE actually performing the operation, and then set it to 0 if that is the case. This prevents cases where you make a value negative for any step in the code which could result in weird problems down the road.

Leveling Up and Dying

They took an interesting approach to the level up process. They created a new class within the CharacterStat_SO scriptable object named CharLevelUps. These CharLevelUps objects just contained a bunch of int and float fields for different stats, and would be the amount to increase those base stats upon attaining the next level.

They then created an array of these CharLevelUps objects in the CharacterStat_SO class. You could then see this array in the editor and set a number of them to create (in this case, it would dictate the max level of the player). The designer could then set the individual values for each of these stats for each CharLevelUps object in the array to tell the system how much to increase each stat specifically upon attaining that specific level.

SUMMARY

  • Control your encapsulation when dealing with scriptable objects
  • Make sure to have checks for max and min values when modifying stats
  • Creating new classes that just hold a bunch of fields and then creating an array of those classes can be a very nice modfiable tool for a designer to work with

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

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

Houdini Assignment - Fuse and Group

Image
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
