LEARN UNITY - The Most BASIC TUTORIAL I'll Ever Make

EXPAND for Time Stamp Links -- This is the most basic Unity tutorial I will ever make. If you are brand new to Unity, or if you want to make sure you’ve covered the basics, and if you want to learn how to write your first C# script - this is the video for you!

Over the course of 2 hours, I go through the User Interface, Game Objects, Transforms, Components, Prefabs, and writing your first C# script to get user input, how to fix your first bugs, and even how to refactor your code to improve it.

"You don't get better at coding, you get better at googling what to code" - Some professional coder

[TheKarishi]

The section starting at 1:59:39 is SO INSPIRING. I feel like Unity could straight-up use that section as marketing material.

[aaronelliott]

Can I just say as someone who's just started trying to learn both Unity and Blender, your videos are the best!

[tomali]

This is one of the best tutorials ever created on Youtube. I can't believe this kind of content is free to us all, what a world we live in.

[ChadWellsForReal]

This is like my 5th "Unity tutorial for beginners" that I've followed along with, and this one is the best I've seen. Well done.

[MrAndyjobo]

I am extremely impressed at your ability to assume the viewer knows nothing (as I do), and teach completely from the ground up. AMAZING video, and I think you've sparked my interest in learning more about Unity. Thank you.

[sam.ammatouri]

You have such a great "teacher attitude" and you know exactly what beginners wants to know. Very well done, a wonderful and informative video!

[Weddlz-]

If anyone is having an issue where "Input" doesn't show a drop down menu and "Monobehaviour" Isn't the correct color:
Make sure that Unity's external script editor is set to Visual Studio.
You can change this by clicking Edit in the top left corner, and then preferences.
Also make sure to restart Visual Studio.

Love this guy's dad jokes. "I'm not depressed but I have D pressed" lmao

[chaosmastermind]

"Let's press play and see if this is a fun game.... Nope, still sucks."
Oh if only big game companies did this at least once in their games. LOL

[RoughDonut]

Duuuude the timing couldn't have been any better. Just minutes ago i decided i want to finally start learning Unity and you just uploaded this video!
You are a godsend!

[cathychoi]

Thanks for the best UNITY tutorial! as an Unreal Unser, just Unity starter, I have searched many places, no one really explained that well as you did here, thanks again for your insanely detailed content.

[ironcrossadmiral]

The fact that a feature length film level tutorial exists for free and is this clear and this detailed gives me hope for humanity. You're the best man!

[ttracs]

Finally thank god, a simple tutorial that actually outlines the purpose of the code! You are a saint, everyone else places “beginner tutorial” in the title then goes into high level scripting without so much as an explanation

[DannyCallaghan]

I've been a developer for over 20 years, and I've sat through more video and in-person tutorials, for dozens of programming languages, applications, frameworks, libraries, etc, than I care to remember - I honestly don't recall seeing a better one than this. Superb.

[harshjain]

That "can i" part blown my mind😂😂

[Hangaroid]

19:26 I laughed so hard when you said "I can reparent this child object and then the problem pretty much goes away"
Honestly there are so many professionals giving these tutorials on how to use software and all of them have something about them that is a bit off like how they talk or their sense of humour, but you hit it all out of the park. Congrats.

[DanSpartan]

teacher :-teaches code
-write code
-"why is it not working?"

yep, i would love to know more about this profession

[mrCetus]

This is the best unity starter tutorial I’ve found. I needed something basic to move from my basic 3D modelling and basic programming to get into unity, and this was exactly the right balance. And like other comments, 2hrs video that you don’t want to skip through or get bored with, is something in itself. Well done!

[StubenhockerElite]

Respect, this is the perfect walk through a beginner at Unity needs. No stupid skits, no advertisement, just a solid tutorial. Thanks!
