How to make Space Invaders in Unity (Complete Tutorial) 👾🛸

Learn to make the classic 2D arcade game Space Invaders in Unity. Space Invaders is a 1978 shoot 'em up arcade game developed by Tomohiro Nishikado. Within the shooter game genre, Space Invaders was the first fixed shooter and set the template for the shoot 'em up genre. The goal is to defeat wave after wave of descending aliens with a horizontally moving laser to earn as many points as possible.

NOTE: I accidentally left one clip out of the video of me adding a Rigidbody2D component to the "Invader_Base" prefab. For collisions to occur, at least one of the colliding objects needs a rigidbody. Set the "Body Type" property to "Kinematic" on the rigidbody so the movement of the invaders is not simulated by the physics engine.

This makes a REAAAALLY good way of learning unity. As humans, examples are the ultimate best way for learning things. I wish schools knew that

I accidentally left one clip out of the video of me adding a Rigidbody2D component to the Invader_Base prefab. This is needed in order for collisions to work between the invaders and the player. Alternatively, you could add the rigidbody to the player game object. Either object will enable collisions between the two. You will also want to set the rigidbody type to "Kinematic" since we don't actually want the movement of the object to be simulated by the physics engine.

In general, for collisions to occur between two objects at least one of those objects needs a rigidbody. The rigidbody turns the object into a physics object, and it is the physics engine that calculates collisions. Sorry for the mistake! Let me know if you have any further questions.

Amazing! This was my second tutorial from you and you are an absolutely amazing teacher! Thanks a million for taking the time and posting these. You're a rock star.

I literally came to this video to see how you handled the bunker physics because I'm making my own clone of Space Invaders, only to realize that's one of the only things you left out of here lol

Millepede would be an excellent retro -project for many to tackle and admire.

THE MOST ORGANIZED AND CLEAN TUTORIAL EVER THIS IS AMAZEBALLS

[captainkeller]

Hey mate, havnt watched much yet but the little I watched definilty want me do keep follow the stuff you post. Keep it up. I guess my evening will be spent watching all the stuff you did so far.

[paulcrawley]

Fyi the new input system works very well with your tutorials and might help some new peeps get used to it, anywho great tutorial

[vgmz]

why just 571 views this is one of the best tutorials ive ever seen (sorry about my english)

[tayfunyirdem]

AWESOME! Best game development tutorial series i've ever seen.

[uniKorn]

Easy to follow tutorial once again, for beginner like me 👍 Learned a lot about prefabs 🧠

[johncleve]

Nicely done! Used to play around w/ XNA years ago, and just now dabbling with Unity. Great tutorial! Sincerely appreciate your time on this.

[gazzer]

Thanks for the Space Invaders tutorial, it was really well explained. I learned a lot!

[jackgr]

Thanks man cant wait for more arcade games tutorials pacman and others watching your videos i manage to understand how to make my games byutifull sprites are better camera size everyithing is going well on developing my first game 😊❤️ Missile Command tutorial would be great too

[kianfransen]

Instead of the destroying bunker physics i came up with a idea to shrink the size of the bunker and after the size shrinks 3 times it explodes. It is very cool and very easy to make.

[leerag]

Ps beginner first time on unity . Thank you for doing tutorials to teach even total beginners

[arronshaw]

Thank you for providing these high effort tutorials for free! I will sub to patreon in a few months when my financial situation is a little better :)

[bencorrigan]

Hey Zigurous,
Amazing Video as always :D
It'd be great if you could make a tutorial for the full game state as you have mentioned.
Thanks :)

[GaBoyInKy]

This was a solid tutorial. Thanks man.

[seanhunt]

Your first three videos were amazing!!! This video felt rushed and you did not explain things like in your previous videos. You are a really good teacher. You just did not see like you were into making this one.
