Looking for help installing and setting up a Unity for the first time or just need a refresher on the editor? Then this is the guide for you! This guide is tailored to what you experience as a first time unity user.
I’m going to assume we’re starting from absolutely nothing! Our first order of business before we can get started fiddling around with the game engine is going to be downloading it in the first place.
Unity helpfully provides a version selection and wrangling tool called Unity Hub. This lets us set up and install multiple versions of unity, access resources, and see a list of our projects in one place - so lets select the ‘Download Unity Hub’ button.
Go ahead and install the application - the default location it chooses is just fine. Go ahead and launch unity hub.
You’ll likely see a notification at the bottom about not having a valid license - that’s alright! Personal use licenses for Unity are free so long as you’re not making over $100,000 a year using unity for personal or small business uses. We’ll fix this situation by creating an account and logging in.
Select the account icon and sign in by either going through the process of creating a new account, linking a third party account, or logging into an existing account. It makes no difference to Unity if you use a 3rd party account as your sign in or make a new one - but either way, ensure you’re signed in before continuing to the next step. You’ll know you’re signed in because you’ll see your initials in the upper right of Unity Hub instead of the generic person icon.
Now, we’ll head to the license management section. If Unity Hub didn’t open to it by default, you can either click on
Manage Licenses on the notification if it’s still up, or select the settings cog and then choose License Management. We’ll then select
Activate New License, and choose
Unity Personal. Select the description of what best applies to you, and click done. You’re now set to get untiy installed and set up!
Head back to the main unity hub page, select the installs section, and then click on the
add button. A version selection window will pop up - if you know you need a specific version because a tutorial or something told you to get it, you can head to the version archive link to get exactly what you’re after. Otherwise, the recommended LTS version provided is generally the safest choice. Select ‘Next’ to move on to the module selection screen.
By default, Unity will select the minimum required number of modules to install on your system, and generally also the documentation which is nice. In addition, It’ll select “Microsoft Visual Studio Community” on Windows, which we’ll want to install. If you’re reviewing this guide later to install another version or you already have the visual studio version specified on your computer, you can uncheck the box. If in doubt, leaving the box checked won’t harm anything.
Later, if you’re looking to install modules to make it easy to put your game on, say, iOS or android, you can head back to the installs section of untiy hub and modify the modules of your untiy install. Once you’ve confirmed your selections, click next and go through the install process.
It’ll take a bit and a separate install window for visual studio will probably pop up, but once everything is finished, your installs section should look something like above! If that all looks good, then you’re now ready to create Unity projects!
There are two options we’ll discuss for creating a unity project - using a premade educational refernece or creating your own project. This depends on your learning preferences, and it doesn’t hurt to explore both options. It’s nice to be able to reference an exising project to see how you can do something, and you can find these premade projects and some tutorials in the Learn section!
For this guide however, we’ll be using an empty project. Start by making your way to the projects tab in Unity Hub, and select the ‘new’ button.
Already there are a variety of options - which one do we choose? Well, no worries. It doesn’t matter which one you choose really, all the choices do is impact some defaults for how your project shows things to your user and to you while you edit. Unless you have a specific set of defaults in mind, I’d recommend choosing 3D project by default regardless of your project contents. Let unity load up, and you’ll be presented with the editor!
Awesome! We’re in, and unity is set up. Now for some basic information to help you navigate around this pile of buttons.
The editor can be a bit intimidating at first, but I find it best to provide a rough overview of the larger sections and not get muddled in details just yet.
So… what are we looking at then? Well, when writing a document, you save a text file - when making a digital picture, you save an image. In Unity, we create ‘scenes’. Scenes are bascially collections of things appearing in our project. We need at least one, but can have many! These are saved as
.unity files. In general, one of these is always open, and one has been created by default for you.
Now lets have a look at 7 key areas in the default unity editor layout.
Transform component, so it’s provided by default on all GameObjects you create or that are provided and can’t be removed.
Scene, this is where you can edit your game world in physical space while it’s not running (or temporarily while running, tho changes will revert when you stop), and is the visual representation of the things in the Hierarchy. you can think of this as the behind-the-scenes developer view.
I fully expect that this may need to be referenced multiple times, so while I’m creating a cheat sheet, here’s some common vocabulary you may see if you search around for tutorials or look for Unity documentation.
I skimmed over a lot of buttons and menus, but they’re not necessarily needed up front if you’re interested in writing code - but what better way to learn than by pressing them! As a heads up, some windows and buttons don’t do anything unless you have an object selected in the hierarchy or scene, so you’ll want to be sure you have something selected before clicking about. Most buttons have to do with manipuating items you’ve selected in the scene - resizing, rotating, or moving.
Congratulations, you’ve now got Unity installed and you’re ready to take your first steps!
If you have a little programming experience, I’d check out some of the other posts on this website. You may find that starting to write code is one of the best ways to learn about interacting! If you’re looking for more info on the editor and its sections, checking out Unity’s website, or other tutorials which cover some of the vocabulary and sections above in greater detail.
