@north3269 2 года назад

I absolutely love your videos! I'm actually new to coding and stuff and I'm outta plans. Your tutorial is so easy and simple to understand while these thing usually hurt my brains. There are only a FEW RU-vidrs who can actually explain it simple and stuff and you're included! You're actually too Underrated.

@treroldan8707 2 года назад

This is an amazing tutorial, love your overall vibe! I am brand new to both coding and game creation and this was so easy to follow. I love how you take the time to actually describe what each line of code is doing and why. Definitely going to be subscribing and checking out your other content. Thank you so much, and keep making videos!!

@JamesTolias Год назад

This tutorial is absolutely incredible! I am a new software engineer with about 1 year of experience and I am getting into Game Development, and this guy uses the best practises, makes a pixel perfect game, and explain everything pretty accurately!

@adityaburadkar9002 Год назад

Thank you! if anyone having problem with scoring as a TMP then add 'using TMPro;' and instead of text use 'public TextMeshProUGUI scoreText;' and that should solve the problem.

@LaurenArmiland-yw9vh 7 месяцев назад

Thank you!!!!

@silverglasss6786 Год назад

Coldn't be more pleased with a tutorial than this! It worked out perfect. The background music created a really good atmosphere as well.

@seemslegittome7726 2 года назад

Such an underrated channel, I love the wole tutorials since he explained what is the use of the codes and really fixed the problems. I hope you gain more subs and views cause you deserved it. Hoping to learn more about your tutorials.

@panaxio_oficial 8 месяцев назад

Bro I love you so much, starting with Unity was my new year's resolution, and today (almost at the end of the year) I finally stopped blaming myself for not being consistant with the official courses that I was watching, and your videos have reminded me that definitely the best way to learn is by doing and not just watching boring videos from an official course. THANK YOU SO MUCH!!

@Zigurous 8 месяцев назад

Thank you so much for your support!

@soular7159 2 года назад

This was the first time I've ever worked with c# and the first 2d game I've made with u you it was such a help to have this tutorial. Thank you so much!

@UchihaAshuke 2 года назад

Thank you for all your effort. I have started learning unity again after multiple failed attempts earlier. Love your contents. Keep up the good work.

@rafaelpatricio8022 9 месяцев назад

This video helped me a lot to produce a project for school and to learn a lot more about “Unity”, which is why you just gained a follower. Thank you very much.

@DarkMaaastersTubeLoL 2 года назад

I don't have any patience usually but man I've watched your tutorial fully. Very nice explained and it went smoothly. Keep it up.

@rfernandez83 2 года назад

Bought me a mac about a month ago to get in the game app biz. This definitely helped learning how things work, because the unity tutorial like John Lemon doesn't feel like it's explaining very well what it all does compared to how you are doing it. Thanks for the video.

@SierraGuerrero 2 года назад

Amazing tutorial! Thank you so much for taking the time to create, share, and explain the process.

@sreemayeeghosh 6 месяцев назад

Extremely well explained steps! All assets and scripts have been carefully cleaned up, organized and rendered bug free👍🏻👏🏻

@joshfatal 6 месяцев назад

Thank you so much for making this channel. I'm a nobody hobbyist game developer still trying to learn as much as I can and I felt like there was no hope to getting into this field (no degree, no experience.) Aside from learning a lot from your tutorials (which are very well produced and paced) I'm planning to make most, if not all of the games you've taught on here, and add my own modifications so I can some day put to gather a portfolio website. For Flappy Bird, so far I've added a feature that puts a translucent copy of the next set of pipes on the right side of the screen shortly before they pop into view. I have the game set in 9:16 aspect ratio to mimic a phone, so this feature I feel makes the game a little bit less frustrating (not really, it's still Flappy Bird.) It's a little buggy but it actually works and I'm proud of it. Thank you again for doing this, keep on creating!

@scottbarba9247 6 месяцев назад

These are great!! I'm teaching game design using Unity in AP Computer Science Principles at the high school level and your use of functions, calls, loops and arrays is perfect for meeting AP's criteria!!!

@Aerionix1 Месяц назад

Doubt anyones looking these days but curious why we use time.deltatime for the change to direction using the gravity var and also for updating our position, but not when we change direction earlier with our strength var. Thanks for these man, i dunno if you're still doing this stuff but looks like it helped a lot of folks.

Great tutorial.

Would love to know how to add add the sound when you click/tap the screen for the bird 🤔

@user-ic1wi4do9z 4 месяца назад

Did Finish it Today! With the Github Element for the New Text I needed to Create a TextProMesh Font to use it. Also I somehow overlooked the Part where you did add 2DBoxCollider to the Player and was endlessly long struggling to find out why my bird aint colliding. Me as a Newbie didn't understand that RigidBody2D not count as a Collider.. :D Beside the New Text I also needed to declare the text differently in game manager but beside that The Video still works in 2024! Loved it as Entry. Now im Going through Unity Learn and come C# Free Course to learn the Basics. Flappy Bird here rly helped me to understand some basic parts , even tho I did almost copy paste a lot. Thanks for this!

@safakaya2904 Год назад

That was amazing tutorial !

@alsowow 27 дней назад

A fun tip for people who just finished the tutorial is to add some more things to your game with the things you learned throughout the tutorial! like a simple highscore counter for example

@sync7509 Год назад

Assets\Sorpts\player.cs(67,30): error CS0246: The type or namespace name 'GameManager' could not be found (are you missing a using directive or an assembly reference?) 😢😢

@error-hz8qc 2 года назад

whenever my player collide with ground or pipes my game is throwing me this error NullReferenceException: Object reference not set to an instance of an object Movement.OnTriggerEnter2D (UnityEngine.Collider2D other) (at Assets/Scripts/Movement.cs:56) EDIT:- I did't attach the Gamemanager script to the GameManager Object.

@vaisakhrs7046 Год назад

Inside the ScreenToWorldPoint function,here as our left edge is at (0,0),we can just say Vector3.zero.But how can I provide a vector3 component of any other particular point??

@yan8368 2 года назад

The scoring text is behind the background, changed the layer order but it's still the same, how to make it in front?

@user-zl9dx4id2g 2 года назад

When i downloaded the sprites and everything, it put it in a folder and now i cant get anything out of the folder.what do i do

@SkidMania 2 года назад

This is a great tutorial, thank you very much. I am right near the end of it right now and have a question. I notice that when the bird touches the ground or a pipe that the bird is always in a slightly different position like it gets caught at a different time rather than stop pixel to pixel with the colliders at precisely the same time and distance each time. How come it does this and is there a way to get it to react in a way where it will be the same every time. Thinking of your asteroids tutorial, when the ship crashes into the edge of the screen it is precise every time like it hits a wall, it doesn't go partway through like the bird does with the pipes and ground. Any ideas?

@minimaxpowertv1617 Год назад

Any idea on how to configure another choice in the background and the pipes (like skin for day, skin for night) ?

@david04x 2 года назад

Amazing video. Thank you so much!!!

@REDLION5921 9 месяцев назад

Great Tutorial! I just have a question, my "score" text is not wanting to go into the GameManager slots but all the other ones like, "Player", "PlayButton", and "GameOver" go in just fine. The "score" text is the only issue I have.

@morrismannen6221 2 года назад

When I try playing my game it wont change sprites, even though I have selected two different sprites to change between. I have tried copy and pasted your code into mine but still it wont change. Any ideas as to why? EDIT: somehow I removed the script and tried again and now it worked, dont know what I did different really.

@cx717cx717 7 месяцев назад

Great lesson. Thank you!

@GreatGamingGoodness Год назад

I know no one will respond, but when I type, "private void OnTriggerEnter2D(Collider2D other)" the other won't turn blue and debug says "Object reference not set to an instance of an object" when colliding with pipes and the ground. What am I doing wrong?

@meteach 3 месяца назад

@ziyaadkabani8312 2 года назад

My score doesn't increase when I go through the pipes, I went back through the video but didn't see any errors. Do you know what it could be?

@lxl7413 2 года назад

Hmmm..... everything about this tutorial is awesome. I just came up to 1 problem. When you play the game and you hit the ground, it pauses but when i click the play button it continues forward and does not reset properly. Since I went through all this in a day and do not have much experience with this I wanted to ask you guys for some tips and what part to work on to fix it? When the bird collides with the pipes and i click the play button it resets, but not with the ground. Thank you a lot in advance anon for helping me structure the puzzle in my head !

@alphamvmnt 3 месяца назад

Awesome video! Can you do a tutorial on adding a menu and also an animation tutorial screen before the game starts?

@fredericdompierre4986 Год назад

Thank's , Nice tutorial ! In my Unity Version, I don't have UI button but only TextMeshPro Button. It seems to cause problems with SetActive. Any ideas to fix that Problem ? Best regards, thank's !
