Unity 4.3: 2D Game Development Overview

November 12, 2013 in Technology by

Today, we’re thrilled to announce the launch of Unity 4.3, and with it, the highly anticipated introduction of our new feature set for 2D.

To give you a better insight into the development process, we have created a demo project to show you the ropes. For a head-start on learning from this project, take a look at the video below, which walks you through the main points of what it takes to create a 2D game in Unity.


Download the demo project and take a look through it today!

What will you make with the new 2D tools? tell us in the comments below!

If you haven’t done so already, download Unity 4.3 here.

GAMES! That is what I will do with it!

12 Nov 2013, 3:18 pm

yeah…i been waiting for this

12 Nov 2013, 3:20 pm

hopefully I can integrate my project with smoothMoves

12 Nov 2013, 3:23 pm

I will dissect everything in it! The features!!! They look awesome!!!!

12 Nov 2013, 3:30 pm

So awesome! It’s what we’ve been waiting for.

12 Nov 2013, 3:43 pm

Damn i was about to see any date when unity 4.3 will be released then refreshed the page and got almost heartattack! I love you dev team!

12 Nov 2013, 4:18 pm

This is one attractive video. Well done.

We have been waiting for 2D in Unity for a long time, maybe too long so now I need to forget everything I know, and learn them again.

I am going to port my windows phone game to unity with your amazing 2d tools ! And , of course , after that will develop new games :) !

Awesome stuff!!!! Although I secretly was hoping that this was “the” version 4.x that would have the new unity gui… *hiddensadface*

12 Nov 2013, 5:23 pm

New UI ls the one I waiting for !

12 Nov 2013, 5:27 pm

Holy moly, it’s finally out. Perfect timing and long awaited. I have many 2D projects that all suddenly look much more exciting now that I can implement them with the native 2D system. Getting to work on my shootemup should prove much more productive now.

12 Nov 2013, 5:34 pm

@@”Yipeee” for the 2D and @@”hoooh” still to wait for the NEW UI….

Unity – Full of surprises. thats why every game developer loves it.

GREAT JOB by Great Team to provide us a Great Tool. ;) UNITY UNITY UNITY

12 Nov 2013, 5:48 pm

Hi. There will be a “project tutorial” like these? or something even more step by step than this video?

Thank u in advance :)

12 Nov 2013, 6:27 pm

@SarahLupo, thats the plan, just not quite yet.

Christmas came early this year …
Great Job ! :)

12 Nov 2013, 7:30 pm

So does this kill NGUI?

12 Nov 2013, 7:45 pm

What took you so long !!

12 Nov 2013, 7:47 pm

Give us a more detailed tutorial for 2D!

12 Nov 2013, 7:49 pm

I’ve really been looking forward to this for a long time. I’ve been using a decent framework to help with my 2D development, but it often felt like I was fighting against the engine. Now, for the conversion…

12 Nov 2013, 8:17 pm

Downloading as of now, I plan to make a 2D game with it and many more in the future.

12 Nov 2013, 8:41 pm

Super stoked that this is out, thanks to the team and all the beta/alpha testers out there. You know who you are ;)

12 Nov 2013, 8:52 pm

Since 2D is now officially supported, I’ve seen solutions in the past but is there a new feature or what is Unity’s solution to have the player jump through platforms from below but stopped on top.

12 Nov 2013, 9:26 pm

What’s the story with “Pro” features? Does it not auto atlas? Does this mean that we essentially have drawcalls for every different sprite?

12 Nov 2013, 9:32 pm

Awesome birthday present! Wasn’t expecting it this early. Distracted everyone at the office after seeing the news pop up in my email (Google Alerts). As usual, just a bit disappointed GUI didn’t make it to this release. But we believe firmly that what ever it is you’re brewing behind those walls will blow our minds, when it’s finally ready.

Thanks for adding in the new Mono 4.1 (Xamarin studio). Made me dream about unity 5 spotting .NET 4.X and the new SGEN GC and my personal favorite, extensible language support.

great work team. Hope I’ll be saying a bigger thanks on the 22nd ;-)

12 Nov 2013, 9:43 pm


12 Nov 2013, 10:04 pm

Finally, Auto complete with Unity Script!!!!
I love u guys!!!

12 Nov 2013, 10:19 pm

Why it’s impossible to export Unity’s 2D Platformer project to Flash (fatal errors after loading SWF)?

13 Nov 2013, 3:41 am

For someone already experienced with unity, I’m finding the video full of things I already know (health scripting etc) and vague on how the details of 2d workflow. But that’s perfectly fine. Besides, a lot of new users are coming to unity because of 2d support and the video is serving as a good general introduction to them.

13 Nov 2013, 3:49 am

Thanks unity for the 2d feature.

Thanks. My students learn to code quickly in Unity. Now we can use it for our 2D projects too. The growing learning sections are fantastic, and the Asset Store is a big help. You guys have had a very positive impact in our school!

13 Nov 2013, 10:17 am

Awesome as always!

Interactive maps in my 3D game(s)

14 Nov 2013, 3:25 pm

Please keep in mind that we’ve not finished with 2D yet. New features will be coming out in pretty much every release from now on – as quickly as we can cook them!

14 Nov 2013, 4:18 pm

Are you adding 2d skeletal animation in future?

14 Nov 2013, 6:22 pm

I Need New GUI

Oh my this is so exciting! Amazing tool :)

15 Nov 2013, 10:26 am

Should you remove PVC culling?
It’s Important to low performance device
don’t think witch function is removed like jobs, We are not users but developers

15 Nov 2013, 5:46 pm

Guys I have a question about the 2D demo, which is awesome by the way!!!

What are the steps to put the “Gun” prefab inside the “hero”?
If you click the “hero” prefab in the Prefabs folder, in the inspector you cannot see the “Gun” script, but if you expand the “hero” by clicking in the prefab icon, you can see that it has the “Gun” prefab there. I want to do exactly the same thing but I can’t figure out how to get the “Gun” prefab inside the “hero”. Any help would be very appreciated.

Great video, excellent tutorial. Let’s start creating…

18 Nov 2013, 7:23 am

Does anybody knows a good tutorial to create a 2D game from start to finish in Unity 4.3? Something like the game above, but step by step? Thank you.

19 Nov 2013, 10:16 pm

Gotta say the fact theyve done 2d is exactly what i needed but for people new to unity this video is absolutely terrible

Really appreciated if some one post step by step tutorial for beginners.

20 Nov 2013, 2:49 pm

Awesome… That’s a big surprise.

20 Nov 2013, 2:55 pm

May be this could help for those looking for tutorials. Uploaded this week.

20 Nov 2013, 10:56 pm

Would be awesome if the Asset Store would actually load. Is there a link where I can download this directly my Asset Store is stuck on ‘Loading…’.

28 Nov 2013, 4:40 pm

Looking forward to testing out this feature…thanks for adding it.

Time for Will to write a new book on 2D game development in Unity I think ;-)

29 Nov 2013, 12:12 am

It’s coming! next year..

2 Dec 2013, 8:25 pm

Hi Will, sorry for stupid question: by “next year” you mean jan/feb or farther? :)

3 Dec 2013, 11:34 am

Further tbh, I want to cover new UI system and have a whole new take on Unity with my next book, so I want to take some time over it, sorry!

10 Dec 2013, 1:39 pm

Hi, anyone have an idea how to run 2 animation on one single sprite? My case: i wanna my enemy run a simple mouth animation (4 frames) while it walk on a loop path. One more, is there a easy method to duplicate a sprite in a row like for a background tile? Thanks to everybody

10 Dec 2013, 2:19 pm

@Alessandro – make the mouth a separate sprite that sits in front of your character, and then change its animations on a new layer in the animator.

11 Dec 2013, 9:50 am

@Will Goldstone Thanks for useful hint! Any advice on how to easy duplicate on a row a background tile?

11 Dec 2013, 10:09 am

Currently the best way is just to parent something for organisation, then duplicate and use V for vertex snapping to drag a point and align it.

11 Dec 2013, 10:59 am

@Will Goldstone Thanks again.

16 Dec 2013, 1:37 pm

Hey, great video !
can we find the music somewhere ? :)

16 Dec 2013, 1:37 pm

16 Dec 2013, 1:40 pm

A question so good you asked it twice. It’s a piece by Joe Brammall – see, but the piece is something we commisioned from him, so not freely available, sorry!

so please help .. y there is no video … :(

17 Dec 2013, 1:51 pm

@Muhammad, as far as we know you should not see any 404 errors – our sites seem to be up and fine?

17 Dec 2013, 1:51 pm

This looks so good! I have been developing 2dGames in java up until now. Will give Unity and c# a try. Hope it will be as good as i assume it will be :)

17 Dec 2013, 1:53 pm

Hahaha! Why is there a picture of a complete stranger as my avatar?! Hillarious!

24 Dec 2013, 5:19 pm

Very cool

30 Dec 2013, 12:05 am

I downloaded 4.3, very excited about this feature… However, My old project crashes Unity when it launches, so I tried to download this from the asset store, thinking this project wouldn’t crash.
Well, in order to download it… It wants to open the asset store, but unity crashes when it launches…

8 Jan 2014, 11:09 am

How to know the bundle name of this so that I can test it on my android device??

22 Jan 2014, 11:51 am

It’s a great Stuff, for dealing with 2D technology games.

22 Jan 2014, 11:54 am

Amazing efforts by 2D…:) I really appreciate their work……..Its really Amazing!!!
Great Job :)
