Issue #94 - Patterns, Math, and VFX

Dig into this week's issue with some programming patterns, 3D math techniques, VFX tutorials and ton more. Enjoy!


Model View Controller Pattern for in-game UI - This article describes an approach to structuring UI in Unity. This approach is based on the Model View Controller (MVC) pattern, but it’s slightly adapted for Unity. This isn’t the only way to structure your UI, but it has worked well for all my previous Unity games.

Pooling WaitForSeconds in Unity - Pooling does not have to be confined to visual elements. Another classic optimization for Unity is the WaitForSeconds yield instruction. [For a great alternative, check out More Effective Coroutines [FREE]]

Climbing ladders mechanic in Unity 2D platformer games - Climbing ladders is quite popular in 2D platformers. This mechanic allows players to easily move their characters above and below different parts of the levels without the need to jump or fall. It introduces another layer of complexity to game environments. In this tutorial we are going to look into how we can create ladders and give our characters the ability to climb them.

Math: line intersections - Lately a lot of my shaders have used a bit of raymarching, where I primarily rely on finding the intersections between a line (ray) and a shape. In this post I will go over the general approach for calculating these intersections and provide a list of HLSL implementations. The shapes discussed here will include planes, quadric surfaces (e.g. a sphere) and some useful combinations of them.

Put a Little Shake On It - Creating Camera Shake can be achieved in a few different ways. I decided to use animation to control the change in my camera’s Orthographic Size. This approach will allow me to create an animation clip that I can play every time my player takes damage. The process to achieve this result was quite simple.

Unity Arcade High Score Table - Xevious, like many arcade games, has a very basic high score table. The user has a fixed amount of time to enter their initials. The mechanism for it is to use the joystick to move the characters up and down the alphabet. Once you have the correct letter you press fire and it moves the virtual insertion point on by one.

How to run jobs using ComponentDataFromEntity in parallel - ComponentDataFromEntity is one of the most commonly used API in Unity’s Entities package (ECS). The main drawback is that once you use it in a job, you can’t run it in parallel as is. The Unity runtime won’t even allow you. It will just throw an error. You can still make it run in parallel but there are rules and I’m going to show you how in this post.

Basics of Mipmaps in Unity Part 1! Import Settings and Custom Mipmaps! | Game Dev Tutorial - Mipmaps are scaled down versions of textures Unity generates and draws when a texture takes up a small area on the screen. This saves memory and looks better to boot! In this video, I go over Unity's mipmap generation settings and show how to create custom mipmaps. I also quickly demonstrate a cool trick Nintendo used to make Mario Sunshine's water!
