How to Make a Simple Unity Open World System

How to Make a Simple Unity Open World System

Greetings, in this Unity tutorial we shall be looking at how to create a simple open world system. We will be creating a simple chunk loading system. Basically, we will divide our world up into chunks in the unity hierarchy. We will have a parent object for each chunk. Chunks don't need to be the same size.

Each chunk will contain all objects that belong to the chunk, like trees and other parts of the terrain. This is the core concept of this unity open world system.

We will then create a chunk loading script. This script will check the player's postion and compare it to the position of every other chunk. Any chunk that is close enough to the player (within our render distance), we will activate. Any chnk that is too far away (out of out render distance), we will deactivate.

When deactivated, the objects will use less RAM and won't have their update functions called. This will imrpove performance. We can do this by making an open world chunk loading system in Unity. Open world chunk loading is similar to what occurs in games like Minecraft.

In this unity open world system tutorial we will call our chunk update function every second. You can customise how frequent this is. You can also change the code, so we call our chunk update function whenever the player moves. It all depends on what your game needs.

Now with this simple open world system in unity, we can have big open worlds.

We will do more tutorials covering more advanced topics in the future, relating to open world systems.

This tutorial isn't designed to give a complete solution for huge games. Just to get you started on the road to optimising your game. This Unity tutorial is just an open world chunk loading system for Unity.

Thanks for watching this simple Unity open world system tutorial that uses chunks.
