Beginner Godot Tutorial - Make Flappy Bird in 12 Minutes!

[@bedang1058]

Annnnd thats how you watch a 12 minutes video in 1.5 hours !

[@jankutac9753]

hell yeah. I mean would it kill him to pause a little bit between actions, and show what he is clicking on a bit longer than half a second? :-D

[@Ranamo_]

​@@jankutac9753 so true

[@Jetski1Teterium8402]

That's why i dont like the video and i didn't understant nothing

[@excelucate]

Thank you very much, I'd say one of the best explained. You do need a high level of attention to detail, it took me two attempts to make it work (says a lot about me i guess). I can understand the editing took a lot of time and effort but in some places it was not easy to follow so lowering the setting playback speed helped. Having said that this was a brilliant video and great to see someone make a complete game with all of the code available. Keep up the great work it is appreciated!

[@CodingWithRuss]

Thanks! The funny thing is that with all the editing, this video took me about as long to make as it would have if I made a full length tutorial 😅 Glad you found it useful though!

[@moza1793]

Thank you so much for the guide! I just tried godot this year and haven't fully grasp the UI yet. But, this video explained it very well for a beginner. of course it's probably will be better if you can slow it down at some specific point. I'll definitely watch the other guide to make games!

[@محمدالكهالي-ف3غ]

i agree :)

[@ilhomsoliev275]

Keep doing complete projects on Godot 4, you are gold!

[@yeaglaceshorts546]

I used this to spawn in a ball for a new plinko clicker I am making. It was super helpful. Thanks!

[@Sabbalab92]

Thanks for this. I've been trying to learn GDScript. I didn't understand everything you showed, but this is definitely a good start for when I make more progress.

[@CodingWithRuss]

Thanks! Yea this video is a little bit fast, I probably shouldn't have called it a beginner tutorial as it's difficult to follow if you've never used godot before.

[@dragosilies5764]

Great tutorial, I like that you didn't spend too much time explaining concepts. Great when coming from Unity

[@CadeHLife]

After following a few other in depth tutorials to get a basic understanding of core Godot features, this was a fantastic next step for me! Such a fast and rewarding way to help grasp concepts and actually prove to people that they can make a game. As I was pausing and copying code it had me thinking "oh yeah that makes sense" and "OH so this is connecting from what we already implemented here" I will definitely be checking out your other videos. Thank you!

[@senlee325]

Very nice tutorial. My first time using Godot instead of Unity. There was some hiccups at first, but I learned a lot from this. Got a working game completed.😀

[@FriskTemmieGoogle]

Idk if this bug is because of the new Godot version, but 5:28 didn't work for me. After messing around a little, I figured that the reason was that the variable "scroll" didn't have a type assigned to it (I'm sorry if I'm making some kind of mistake with the proper names), so changing the line 5 from "var scroll" to "var scroll : int" fixed the problem and let me run the game with the ground moving

[@FriskTemmieGoogle]

09:05 I found another bug here which could also be from the version. My pipes still didn't have collision and the pipe scene had a yellow triangle on the collisions, saying that they couldn't be connected to a sprite2D node. I changed the order, connecting them directly to Area2D "Pipe" node and that fixed everything. I ofc changed the names for better understanding of what was what

[@FriskTemmieGoogle]

09:57 now I realize that I just did it wrong when I was setting it up, mb

[@Cyynapse]

i really like how concise this is. it encourages you to actually learn the software instead of just copy what you see

[@CodingWithRuss]

Thanks!

[@FriskTemmieGoogle]

really good tutorial! It was perfect as a "hello world" to get me used to this game engine. I was easily able to change things to my liking and even add a "Get Ready! "TAP TAP" screen, like in the original game. I'll probably add the ability of changing the color of the bird next as a little challenge

[@CodingWithRuss]

Thanks! I like the little tweaks you're adding :)

[@rohitsoni2109]

Great tut. On point, no time wasted.

[@Wallee580]

I've been playing Marshmallow Land (it's a built-in hidden Android game) so it's quite good timing that you make this. xD

[@CodingWithRuss]

I had to google that, can't believe I never heard of it before...I've had an android phone for years 😅. Looks like a very similar concept game.

[@Multifandomguy]

4:07 hey I got an error here when I clicked play, the engine says to me there's an error, which is the reset() function isn't declared in the original Bird scene is there any solution to this glitch ???

[@BenitoBeni1414]

I have the same glitch, idk what to do

[@tjjfhdgdhtfwtwthdjffgxhfhxhwjn]

this error should mean that you haven't created the function reset in the Bird.gd script. when you declare it it should look like this: func reset(): falling = false flying = false position = START_POS set_rotation(0) You may have accidentally declared it inside another function (for example the _ready() function)

[@ttdnz02]

try using _reset()

[@cccornel5965]

After following the video and doing everything in it, I found out I suck a FlappyBird Thanks for the video

[@diegoandradex12]

Nice and clearly explained! Everything worked here

[@YankaZabka]

Hey Russ, I'd like to ask about the formulas in your tutorial, like: `if flying: set_rotation(deg_to_rad(velocity.y * 0.05))` or `pipe.position.y = (screen_size.y - ground_height) / 2 + randi_range(-PIPE_RANGE, PIPE_RANGE)` As a newcomer to game development, I'm curious about their origin. Are these from your game dev experience, established best practices, or custom calculations for this project? Those techniques work great, and I'd like to learn more about them. Thanks!

[@CodingWithRuss]

Hello. I'm self taught so this stuff comes from previous experience making these kinds of games (I made flappy bird in pygame a couple years back) and also just trying different things and refining them until they work. I try to avoid manually entering numbers and instead use the data available in the game, so that's what is going on with the second formula. I sketched out the position that I wanted to calculate, then looked at what existing variables I can use for reference and came up with an equation to tie them together.

[@gaWalt]

Hello Russ, who did all the graphics for you? I'm still working on your pygame tutorials but I like the look of the Godot games much better. I'll see if I can follow along on this tutorial and just might switch over to Godot for my future games. Thanks, Gary

[@CodingWithRuss]

Hi Gary, I just find them online, there are lots of open source images that can be used with or without attribution. I try to credit all my sources in the video description although I couldn't remember where I got the images for this game so I couldn't reference them.

[@gaWalt]

Thanks Russ and keep on making these great tutorials!

[@vegasdealer777]

Thanks, Russ, for sharing your knowledge. I'm trying to convert a video poker app I wrote in Python/Pygame to Godot 4. After Snake and TicTacToe, I'm finally 'getting' Godot a little bit. I haven't watched Flappy Bird yet, but I'm sure it'll be helpful.

[@CodingWithRuss]

Glad to hear it's starting to come together. I switched from pygame to Godot not too long ago so it's a learning curve for me too!

[@GhostGirlBlues]

been struggling along for hours. more and more issues as i got deeper in. double and triple checked the code compared to the gdscript provided and shown in video. can't get the pipes to appear. and the bird falls through the floor for a very very long time. and the ceiling area detection doesn't seem to be at the right height

[@GhostGirlBlues]

started over from scratch and spent another day struggling through. i finally got it to work. thank you for this and the pong tutorial. what i've learned is that you have to be extremely exactly perfectly precise. part of the difficulty for me is that this one felt a bit too fast. "blink and you miss it" kind of stuff threw a wrench in things several times

[@alexxgg9208]

idk 12 min. rebuilding and really understanding hours xD. very good video but i like longer videos with more explanations!

[@JacobVega]

A really great tutorial. I had managed to get everything working, but after customizing the textures of the pipes to my own designs, the game keeps crashing (freezing/Not Responding) when the "generate_pipes()" function is run. Whenever the timer first ends, it freezes and in the "Stack Trace" window, it says "Cannot call method 'instantiate' on a null value. And then in Stack Frames are below that message in the window, it lists the "at function: generate_pipes" and "at function: _on_pipe_timer_timeout" in the list. I've looked through the tutorial and can't seem to find what's different between the code. Any ideas what could be the problem or how to fix? Note: I don't really know what caused the crashing, because I did get it to work with the different textures for a couple runs of it.

[@JacobVega]

Update: I fixed it. For some reason, the problem was that the pipe scene got unlinked from the variable. Idk how it happened, but I linked it back and it works now. Again, thanks for the great tutorial!

[@benderrodriguez91]

This was very well done, although 12 Minutes video turned into 1.5h of actually doing the steps :P

[@MahmudShuaib]

this short video style is awesome. But it helps if one knows a little Godot. i have used Godot 4 for just a week and i can easily follow along. However the classic ross will work effectively for non beginners. either way this is super cool.

[@paykol3280]

I love the vid dude but i have one problem when i try to run the game it has a error with $Bird.reset() and the error it gives is main.gd:24 @ new_game(): Node not found: "bird" (relative to "/root/Main"). i tried for so long how do i fix this?

[@dezatoosweet]

I think it's because your 'bird' has a lower case b. Make the node Bird and it should be okay.

[@uh7123zz1azxcv]

thanks for the tuts Russ... I really don't like the copy paste approach that you've been using in your latest couple of vids. The old coding along style was much better imho. hope you can return to using that instead

[@CodingWithRuss]

Thanks for the feedback, it's good for me to know whether people like the new approach or not. I thought people would find the code along style repetitive plus those videos take much longer to make so I switched it up. I have a few more short style tutorials planned so once they are done, I'll look at which style is preferred and try to find a balance.

[@PabloJFerri]

Hello im making this in Godot 4.2 and i did all the same and this happen Invalid get index 'position' (on base: 'previously freed'). and the game instantly crash and doesnt let me even execute it. 2 breakpoints are marked. 1) Line of code 10: var screen_size : Vector2i 2) Line of code 60: for pipe in pipes: pipe.position.x -= SCROLL_SPEED

[@itsCH4PO]

I had this same issue. Be sure to add the "pipes.clear()" function below this call. It did this because the "queue_free" method removes the pipes from memory, so it's basically looking for a "null" value when accessing the position.x of the pipe in the pipes array (even tho we're generating new pipes... idk memory management 101 I guess). Not sure if this exactly helps, I'm still learning myself! LMK what happens.

[@Aoi_Hikari]

the amount of times i pause in this video prob equivalent to me watching a 1 hour tutorial, but still, i pretty much prefer this type of fast pace tutorial

[@MoviesManiac-u7r]

i have a problem my charecter is stuck at one place and doens not go up nor done when clicked it just rotates but does go up or down please help

[@TechnicalParadox]

Bird_hit doesnt work for me, My bird continues flying through pipes even after 9:00

[@MannaHay]

I had the same issue. Turns out I'd created the node in the Main scene as a "Node2D" instead of just a "Node"

[@aija_papaya]

Have the same issue. I am trying to make a computer game for the first time at all. Don't understand whats nok... My main scene is "Node". @TechnicalParadox did you solve your issue and how?

[@TechnicalParadox]

@@aija_papaya I didn't specifically fix this issue but I took a Godot course on udemy. Make sure the area or body of the bird has the on_area_entered or on_body_entered linked to the script. If that's good then check the collision properties of the bird and of the pipes, other than that I can't think of anything else it wouldve been

[@aija_papaya]

I found my issue :) In Pipe script the function "func _on_body_entered(body):" was not connected. :)

[@TechnicalParadox]

@@aija_papaya sorry I had typed out a reply earlier but must not have sent it. I never fixed this issue in this project but I took a udemy course for godot since and yeah it's either that the script wasn't connected to the signal or the collision layers are messed up, or you have a mix up between area/body and are using wrong function

[@JetFireHawk]

my bird doesnt go up and down and i am unsure why i have written your code exactly but my bird just flaps once for a second and then just stays in the animation and doesnt move properly he kind of jolts and tilts a bit but its llike he is stuck with a pin to a certain place. is this because i used a different texture than you?

[@brianmcelroy9922]

I love these videos, but sometimes you go too fast and I miss some code lines or something

[@samhagan292]

it keeps on telling me Line 5 (UNUSED_PARAMETER):The parameter "body" is never used in the function "_on_body_entered()". If this is intended, prefix it with an underscore: "_body". and Line 69 (INTEGER_DIVISION):Integer division, decimal part will be discarded.

Im trying to make it go to the center but it just stays on the corner

[@szymon-io8ju]

maybe go into 2D at the top and drag it to the center

Curious how to solve the "clipping" issue with the bird and the area 2d ground node I'm guessing this is due to gravity force?

Stretch collision up a bit higher above ground. No real way to fix it besides using StaticBody2D node instead of Area2D. But that brings its own set of issues.
