Description

Hey Guys,


Welcome to the Ultimate Journey into the creation of a 2D Sand Physics Simulation in Unity 6!


If you’ve ever played those addictive falling sand games, or simply want to create your own Sandbox Simulator with Custom Physics, or even take the source code to experiment with it, you're at the right place !


In this course, we’re going to embark on a Thrilling Adventure through the Fundamental Mechanics of sand simulation games. This, will drastically improve your Unity & coding skills.


First off, you will learn how to create a Pixel Grid World, where every cell matters. This is the beating heart of our simulation.


Once that’s ready, we can start having fun!


  • You will learn how to create Falling Sand Particles, completely custom, without using Unity’s physics engine.

  • We will add Gravity & Movement Rules so that sand flows naturally, just like in real life.

  • You will discover how to Detect Connected Regions using Breadth-First Search (BFS), so that entire shapes and chunks behave as one.

  • We will generate Random Shapes with Colors, and drop them into the world, just like puzzle pieces.

  • And if you guys are hyped, we can simulate Water, which flows, splashes, and interacts with sand in mesmerizing ways.


But that’s not all…


We’ll go deeper into Code Architecture so that your simulation is solid and easy to expand. You won’t just throw scripts everywhere — you’ll learn how to structure your project like a pro, making your engine scalable for future projects.


Along the way, you’ll master essential Game Dev Concepts like:

  • Efficient Texture Updates (so your simulation runs smoothly, we can still improve that further btw ;))

  • Shape Spawning & Collision Detection

  • Custom Managers to control the flow of the simulation

  • Best Coding Practices (so you don’t end up with spaghetti code)

And of course, we’ll add the finishing touches that make it satisfying and addictive:

  • Smooth Input handling

  • Saturation & Value variation for our shapes

  • Faster falling sand

  • Symmetric Falling Sand implementation


All along the way, I’ll give you Tips & Tricks that will help you code faster, smarter, and in a way that makes game dev way more enjoyable.


So… Are you ready to level up your Unity skills and create an Exceptional 2D Sand Physics Simulation that you can play, expand, and even publish?
