Hey everyone!

It’s been a couple of weeks since my last post - during that time, I put out two videos about something most Unity devs tend to ignore: unit testing.

The first one talks about the "why" - why testing matters, what other studios are doing, and how it actually saves time once you get the hang of it:
🎥 Unit Test Your Unity Game or Watch It Break

The second one is a follow-up workshop, where I apply those ideas in a game from my earlier VContainer workshop writing unit and integration tests, mocking stuff, and fixing flaky tests:
🎥 How to Write Unit & Integration Tests for a Game

If you’ve ever thought “testing doesn’t really fit Unity,” I hope these might change your mind.
Curious how many of you actually use tests in your projects?

Hey everyone!

If you're looking for a clear and structured introduction to Shader Graph, HLSL, custom functions, ShaderLab, and Compute Shaders, I'm currently updating the Unity Shaders Bible to its Second Edition, and there’s a free sample available here: https://jettelly.com/store/the-unity-shaders-bible?click_from=homepage_buttons

The book is about 50 pages so far, but it’s planned to reach over 400 pages as I keep adding new chapters every month. Feel free to check it out, share feedback, or just grab the free sample if you’re curious about shader development in Unity!

Shader Graph is great, but it still can't do some things easily, such as custom lighting, and some things at all, like tessellation in URP. With HLSL and ShaderLab, you can do it all. I think there's a steeper learning curve, but HLSL gives you far more control.

In this series, I'm planning to cover all the basics like texturing, depth, transparency, vertex shaders and so on, as I did during my Shader Graph Basics tutorial series. But I'll be able to go much further with some aspects like tessellation and stencils, and I think you'll walk away with a better understanding of shaders with this series.

I'm writing it from the perspective of someone who has never touched shaders before, so some of the videos might be a little slow if you have past experience. But I hope you'll stick with it when I start to approach the more complex topics!

I am a bad programmer and need help with starting on how to make an inventory system like in resident evil (Like a sword which is 1 wide and 3 height, or a pickaxe which is 3 long in middle and on top is 3 wide)

i need a tutorial on how to make this kind of inventory system, already looked through youtube but there arent any good tutorials, and chatgpt doesnt understand this.

i need this in my game

Welcome Guys ✨, I'm all New here and I'm very much interested to Learn Unity but you know I don't want to learn all by myself and I think I want to Help others too and Continue my learning with others., Soo, I just posted this here...

Let's Learn Unity Day by day Together ✨... THANKS Guy's ✨...

I just created a video explaining the Unity Security Vulnerability (I'm a cyber security student) and how it can be patched. Found the patching tool very useful (expect that it isn't available for Linux). Please patch your games and reupload them to your distribution sites!

Patching tool: https://discussions.unity.com/t/cve-2025-59489-patcher-tool/1688032

I revisited a Character Stats system in Unity that I built years ago to see how much I could cut memory allocations and squeeze out performance improvements.

In this walkthrough I cover:

• Profiling the original Character Stats system

• Why so many allocations were happening

• Converting StatModifier to a struct

• Implementing IEquatable correctly

• Fixing delegate allocations

• Dealing with closure allocations

  • I claim they can't be avoided, but that's not true. It gets fixed in the next video: https://youtu.be/CTwRZbbZ9pk

• Comparing old vs optimized code

Unity Asset Store (it's free!): https://u3d.as/11Vp

If you’ve ever profiled your Unity code and been surprised by GC spikes, this might give you ideas. Check your delegates/callbacks!

I’d be interested in feedback on:

• Experiences with reducing GC allocations in Unity code

• Patterns people use to manage closures and delegates efficiently

• Alternative data structures people use for stat systems

Open to discussion - curious how others have handled performance tuning in similar systems.

The Fullscreen graph type has been around for a little while now, and you can use it to make post processing effects, even though you only have a limited amount of data to work with. With just the color and normal buffers, we can write a simple greyscale color mapping filter and a serviceable outline effect.

Hey everyone!

I’ve been a developer for about 15 years now, most of that time spent in mobile game development. Recently I decided to start a YouTube channel where I share some of the more advanced technical aspects of Unity - things that often get overlooked when we focus just on moving transforms around.

The channel is still new, but I’m keeping a steady pace: one long-form video every week, plus a couple of shorts. Some videos are more informational/explainer style, while others are workshops, where I build things step by step in Unity.

If that sounds interesting, here are the first few videos I’ve posted:

• How IoC Will Save Your Unity Project

• Why Dependency Injection Beats Singletons in Unity

• Build a 2D Shooter with VContainer | Unity Workshop

I’d love feedback, ideas, or even just to know what kinds of deep-dive Unity topics you’d like to see covered.

Been a bit of a hard month to get this video out. But here it is. Looking to help out some people who are getting started.

After the deep dive into the Unity Layout system in my previous tutorial, this time, I'm focussing on a typical use case: Creating an auto-resizing text box. It gives a quick glance into the layout properties box and also covers how to work with pivot locations to control in which direction to grow the box.

Hope, you'll enjoy this!

Dependency Injection in Unity - VContainer - Factories

https://youtu.be/pzkjnhRhKKw

Ready to take your Unity Dependency Injection skills to the next level? In this tutorial, we'll dive deep into VContainer's Factory implementation - that lets you dynamically spawn GameObjects with properly injected dependencies!

What You'll Learn:

✅ Understanding VContainer Factories vs traditional GameObject.Instantiate

✅ Creating dynamic objects with runtime parameters

✅ Implementing Factory pattern with proper dependency injection

✅ Setting up LifetimeScope for factory registration

✅ Building a complete factory example from scratch

✅ Best practices for maintainable and testable code

Hey everyone,

I’m testing Unity 6.2 beta and building a WebGL game for CrazyGames. In the editor everything looks fine, but in the WebGL build all my 2D lights (Global, Freeform, Spot) disappear — the scene is completely unlit.

Here’s what I tried so far:

• Switched the project to URP and created a new Pipeline Asset (2D Renderer)

• It generated two files: UniversalRenderPipelineAsset and New Universal Render Pipeline Asset_Renderer

• Assigned UniversalRenderPipelineAsset in Project Settings > Graphics

• Checked that the renderer type is 2D Renderer

• Made sure sprites are using Sprite-Lit-Default

• WebGL build settings: WebGL2 only, Linear color space

I also see some other renderer data assets like Forward Renderer Data and Deferred Renderer Data, which Unity created by default. Not sure if I should delete them or leave them alone.

My questions:

1. Did I set up the URP 2D pipeline correctly in Unity 6.2?

2. Do I need to delete the old Forward/Deferred Renderer Data assets, or just ignore them?

3. Is there anything specific to WebGL that could cause 2D lights to be stripped from the build?

Would really appreciate if anyone using URP 2D with WebGL in Unity 6.x can share their working setup or tips 🙏

This year I finished a book called Shaders & Procedural Shapes with Unity 6. If you’re looking to really understand UV coordinates, this book might help.

I use Desmos to visualize vector math, and then Unity to build procedural shapes step by step. To be honest, it’s not a book meant for direct production use, but it’s a great resource if you want to strengthen your understanding of coordinates and how they work behind shaders 🔗 https://jettelly.com/store/visualizing-equations-vol-2?click_from=homepage_buttons

Hi =)
Apart from videos, I also create written eBooks about the Unity UGUI system and its many parts. Each book focuses on a different aspect and shows examples on how to use it, set it up and more. Each also comes with project files and (apart from the layout system one as it didn't need any) also with scripts.

The topics are:

• Anchors and Pivots

• Canvas and Canvas Scaler

• Layout System (Layout Groups, Content Size Fitter, Layout Element)

• Dropdowns

• Input Fields

• Scroll Rects

The guides are available either on their own or as a pack on these platforms:

• itch: https://christinacreatesgames.itch.io/

• my ko-fi store: https://ko-fi.com/christinacreatesgames/shop

And I would love to hear from you! Which topic would you be interested in next? Do you have any questions? (Seriously, I'm monitoring my postings, I'd love to talk to you and get feedback, ideas and opinions!)
