You forgot to make game over, dude. Anyway, excellent and entertaining video, thanks! I wrote a Tetris game in C++/SFML a couple of months ago. After watching your video, I realized creating Tetris in Unity is a waaaaaaay easier task to accomplish lol

[@jay-tbl]

Couple things to add: Add to the update method: if (transform.hierarchyCount == 0) Destroy(this.gameObject); So if a parent tetronimo object has all child square object cleared theres no reason to leave it around anymore wasting memory, so delete it Also move all the code for moving the tetronimo into a bool Down() method that returns true if it was able to move down successfully and false if not. Then when space is pressed, do Down() until it returns false: while(Down()) {} to make the fast fall mechanic

[@helenbucknall2317]

This is such a brilliant tut! Thank you so much. I usually watch tuts on double speed because they blather on so much. Not Valem! He gets straight to the point.

[@jgbeu]

Great tutorial! I found this after trying to get through another candy crush clone tutorial that was painfully slow and split across ~40 videos. This was a breathe of fresh air; fast and to the point while still explaining the 'why'. Nice work!

[@abdul-io1002]

this tutorial is really cool,but i want part 2,where there is a function of hold and lv speed,i want to learn it

[@pahbody5336]

Also he didn’t do the bag thingy, where it releases all figures before progressing to a new set of randomised figures

[@kaangamgimginnkagnagnkingmngkn]

You can increase the gravity (lv speed) by decreasing fallTime You can make an extra variable in a class that is shared through all objects in the scene, and that variable will hold the information what tetromino is being hold

[@brendandilloughery3316]

Love this! Two ideas: 1. Simple shapes tower defense game. Use circles, color is type, size is strength. You have different shaped towers that attack in diff styles, enemies come from outside screen to center. 2. Occulus Quest is shipping in a few days. Do a full setup from opening package to simple working game. This tutorial was awesome!

[@ennbee]

I just discovered your channel a couple of days ago, but you are already among my favorite Unity tutorial makers. Every video is well thought out, smartly edited (thank you for not wasting my time!), full of lots of great info, and thankfully devoid of a lot of the boneheaded amateur programming I've seen so often. Kudos and thank you!

[@ValemVR]

Thanks Aaron, its for comment like that that I keep making these video thank you!

[@steindattel8313]

To anyone still struggling with a wide rotation angle: The problem is caused, if your Game Object has a different "anchor point" than your individual squares. Try lining up the individual tetrominos to the GameObject Anchor Point.

[@tetelp7656]

Thank you

[@KudosIncorporated]

I had a problem with misaligned pieces, I had to Open Prefab then adjust where the individual squares were, they were 0.25 off alignment in the Y axis.

[@onto6337]

Hey mate :) great tutorials! Just wanted to give a friendly hint that you are one of few youtubers who actually show how to develop for VR with unity. Found you by searching for how to develop for oculus. It's always nice to specialize in some field and there are tons of KZbin game developers already and almost none of them is developing for VR. If you stick with that topic then over the next few years your channel will grow really fast. I will stick with you for more VR content. Cheers!

[@onto6337]

Oh and btw. If my comment is not encouraging enaugh for you to focus on VR niche - Just look at the number of views under your VR content and compare with non-vr c: Wishing all the best and crossing fingers for your success :)

Hey man, great video really gave me a good start on my Tetris clone still need a lot more such as score and a game over screen and a restart state so I'll work on those on my own and maybe try to find some free music to add to it. Hopefully that will complete the vertical slice my professor was talking about anyways great vid and I really found your broken English oddly charming lol don't know why but it added some entertainment to the video for me :)

[@bdenix1997]

i've just started learning coding. i made tetris in c++ as a console app. rotating was the hardest thing to do. cuz ive had to rotate all the squares in a tetromino one by one. i had to do maths and find an equation and turn that into a fucntion. well after countless of tries and giving up and coming back to it again, i found how to do it. but it took me around 2 weeks. after i've seen this video, i was like what the actual fuck? this guy just did it with one simple function, he didnt write that function himself right? was that like a pre coded something? like an api? idk but, if so idk, it kinda makes me wanna throw myself outta window. if i knew it was that simple.

[@darkmatter6467]

Not really. He's using a trick that you probably couldn't use yourself in C++ with whatever graphic libray you were using. What he's really doing is actually rotating the piece, ignoring if this is a valid or invalid move, and after the rotation, he's checking if the piece is out of boundaries, or colliding with anything else, then if yes, he's reverting the rotation. Simple like that. Dirty like that. The only reason this is working, is that Unity is not displaying the rotating piece on the screen while he's playing this dirty trick. What you have tried to achieve is to verify if the rotation or movement would RESULT in a valid move or not, before actually moving the piece. That's why your code was way more complicated and difficult to obtain. Don't feel bad.

[@bdenix1997]

@@darkmatter6467 this comment was made when i had no idea why they called it a game engine 😀 guess that explains the whole situation

[@sampleee]

I think you thought static was the same as const when making sure the player can't get out of the scene. Static allows the value to be accessed from outside the class, const makes it so it can't change.

[@arthurjvnb]

It's not quite that. Static makes something accessible by class, not bounded to any instance. Public makes something accessible outside the class and it's instances. If we combine "public static" it means it's accessible without any instance and it can be accessed outside the class. I hope I could explain it :)

[@arthurjvnb]

But you are right: const makes something not changeable

At 5:24 you did: Move. If it's invalid, move back Why not just do... If it's valid, move ??? That would be so much simpler. It's silly to write that whole line twice, but reversed!

[@mmandersmc]

because that's not how the ValidMove function works. the function only checks the piece's current position, not where the piece is going to be. if he wanted to do it like you said, he'd have to predict the future location of the piece, which would be way more complicated than just moving it back if it's wrong. so, no, it would not be simpler, it would be more complicated.

[@rigzmoviediaries654]

With the line and square pieces, they don't collide with the walls properly. They just collide one block off of the walls or collide one block INTO the walls. I think this has to do with the fact that the square and line piece are the only pieces that don't rotate around a square, but they rotate around a point inbetween their squares. I've been trying to fix this for the past 4 hours and I have no idea how. Any help?

[@Whitefire2020]

ok i know this is a very very very late response but i suggest going to each square and making sure that it is a whole number and not a decimal. If it is a decimal change them so that they form a t tetris with whole numbers, for example if one is 0.19, 0, 0 change it to 0, 0, 0. then change to object that you put your squares in, the one named T Tetromino and change it to something like 4, 17, 0. This worked for me so yeah. Just in case these are the numbers you need for the squares 0,0,0 1,0,0 2,0,0 and 1,1,0.
