Issue #40 - VFX, Tools, Performance, Cards, Holes, Asset Sales, And A Ton More

Quarantine can't stop the Unity community. We've got posts on making card games, hole games, rogue-likes and more. Tips on using ScriptableObjects as replacements for enums and other type checking. VFX and and Shader Graph. Physics, performance, and coding. Whatever your preference, this week has you covered.

Lastly, don't forget the Asset Store Spring Sale has begun, hope on thos 50% off discounts while you can. Enjoy!

How to Build a Multiplayer Card Game with Unity 2D and Mirror - Working with the canvas in Unity 2D can feel complicated at first, particularly if you're attempting to learn the editor while also tackling C# scripting.

Guide: Parallax Cards in Unity - Alexander Ameye allowed us to repost his guide to the parallax card effect in Unity. Introduction: I will give a breakdown of how I made a parallax card shader using shader graph. For this shader, my personal challenge was to do as much as possible in the shader itself without relying on any textures. In the end, the only things I used 3D models for or textures are the little pokemon scene in the center of the card, and the text on the card.

The Game Performance Pillars: The Start of a Journey - Do you want your game to be a success? Do you want to avoid a big chunk of the 1-star reviews? Do you want to work more on the features your players want, and less on the features they don't care about? For all of this, you need to achieve game performance in the broad sense. That includes loading times, development speed and working on what the users want.

Learn to save memory usage by improving the way you use AssetBundles - Whether your application streams assets from a content delivery network (CDN) or packs them all into one big binary, you’ve probably heard of AssetBundles. An AssetBundle is a file that contains one or more serialized assets (Textures, Meshes, AudioClips, Shaders, etc.) and is loadable at runtime.

Build times: Get the details - Updated BuildReport API in Unity 2020.1 beta gives more details about the build times of your project, breaking them down to the asset level. This information will help you optimize your iteration times.

5 Tips for Organising Unity3D Game Assets - Working with a lot of files becomes increasingly difficult without good structure and organisation, so here are my top 5 tips for organising and working with a lot of game assets, that will hopefully save you some time for doing more fun things, like modelling, designing maps and back rubs..

Rotate a point around another from any axis, using matrix, and without using any Transforms - Rotate a point around another in 3d space is not so easy if we want to handle any axis, without gimble lock. The goal of this function is to use pure math, without any Transform whatsoever. Not just for the beauty of it, but mainly because sometime we want to calculate this kind of stuff without having to use, or generate empty gameObjects. I will use matrix, quaternion and some basic math.

Building a Roguelike From Scratch – Unity Tutorial part 5 – Field of View - Welcome to part 5 of my Unity Roguelike Tutorial. Here we’ll see how to implement a Field of View algorithm using Bresenham’s line algorithm.

Asset Variables - Reusability is quite important in almost any development scenario, and the same applies to games as well. One technique I have adopted are Asset Variables or shared variables. These are based on ScriptableObjects in Unity, hence my name for them: Asset Variables.

How to "Animate" Joints - I recently got asked if there are any good reads regarding "active ragdolls" in unity and since i couldn't find anything useful i thought I am gonna start a little tutorial series.

How SharedStatic Works - Burst 1.2 comes with a new feature: SharedStatic. This allows us to write to static variables from within Burst-compiled code like jobs and function pointers. Today we’ll look at how this is implemented by Burst and IL2CPP. We’ll also put them to a performance test to see how fast they are.

Svelto.ECS Internals: How to avoid boxing when using structs and reflection - I had two interesting problems to solve during the development of Svelto.ECS, which in short are: Set an implemented property of a struct, but only when the struct implements a specific interface, from a generic method and without casting the struct to the interface. Assign an object to a field of a struct, using reflection, without casting the struct to an object.

Scriptable Cookbook: Damage Type System With ScriptableObject Enums (Unity Tutorial) - In this Unity3d tutorial we learn how to create and use ScriptableObjects to replace C# enums or enumerations in a flexible and extensible approach. We'll use this to setup a simple elemental damage system with different damage types like fire, ice, and poison. The idea is that we can check equality against the ScriptableObject asset, instead of checking against an Enum entry. We can also add data or code to these objects as needed.

WAV Loop Editor for Unity - Edit .WAV file loop metadata in Unity. Unity has limited support for looping metadata in .WAV files. It allows specifying a loop start and end point which will be used when inside the loop (Audio will still be played back from the start). A very common use case is music with an intro that should be skipped after a loop, which requires precise timing. Most other tools that support this functionality are either not widely available, unmaintained or complicated to use, so this tool was created to allow editing loops with a simple interface directly in Unity.
