Excellent video! The pace was slow enough to get a really good grasp of these core concepts, but still avoided wasting any time. Thanks for making this!

Amazing series, truly! 🥹 As a software engineer rather than a game developer, I find Bevy much more approachable compared to other game engines. The overwhelming complexity of traditional game engine editors often makes me feel like, ‘Do I really need to understand all these features?’ or wonder, ‘What’s happening behind the scenes?’. While Bevy has its own challenges, it feels tailored for developers who aren’t primarily game developers. It strikes a great balance for someone like me. :3 Again, thanks for opening the door to this. It’s definitely something I see as worth learning, and I hope to see you back on UA-cam soon. All the best!

21:31 am pretty sure those comments saying what those are, are self explaned by the code

13:45 there can be Very good use of match in this

also to note when the system has no way to figure out the order based on data it just runs whatever is in the current order shurg it worked when i put enemy change direction after confine enemys

ALso center the camera to fix the window resize issue

also for _ in 1.. (1.0+random::<f32>()*10.0) as i32 { for random amount of ememies that cannot be 0

Also use add_systems() with a tuple for functions for better format

Tutorial looks great, but honestly I am about to give up on Rust just from seeing "something".to_string() .. is this a general indication of how the language is pointlessly verbose?

bros keyboard made the video even better!

Thanks a lot for the tutorial series! Bevy is a ton of fun so far, and you’ve been a great help! :) But I'm wondering, couldn't you get a lot more use out of the components? For example, instead of iterating over the players and enemies separately to keep them in bounds, why not attach some kind of "keep_in_bounds" component and check for that instead? And some of the constant values could also be stored as components to make it more modular. Something like "sprite_size" and "sprite_speed" for example. That being said, trying to optimize the code helps me a lot, so I'm not really complaining!

just wondering, but why do you make all your functions and structs public ? I'm learning on a newer version of bevy and was wondering if those were necessary at the time, or if not and it's just more useful later down the line.

changes to follow in bevy 0.14: game_over_event_reader.iter() => game_over_event_reader.read() app_exit_event_write.send(AppExit); => app_exit_event_write.send(AppExit::Success);

what keyboard do you use? it sounds heavenly

You can constraint player 3 translation Vec3 with Vec3.clamp method. The problem with your approach with window is that it will not work when window is resized, since you check width and height but when you resize the window origin of the world changes and your constraints will be broken. No idea how to fix it tho :D

i had a weird bug where sometimes the enemy movement seems to get stuck (after reaching screen end all enemies move in the same direction and get stuck in one corner) i fixed it in bevy 0.14 with .chain() in the add_systems call - so confine enemy movement will get spawned at after the enemies got their movement and update direction. Maybe this helped somebody else :) - like the series! :)

Very good work. Keep it up

Unity is also ESC . We call it Unity DOTS consist of ECS , Job System and Burst Compiler

Hi @jacques-dev, I ran the game and it kept increasing RAM usage. Could you explain why ? Thanks!!!

Wait... Where are all your semicolons? How are you not getting compiler errors?

so many bevy tutorials just walk through already written code, or go through features in a totally backwards order. thank you for this easy to digest series 🙏

Analyzers, linters, etc.. sometimes mess up and make VSCode behave poorly or show up non-errors. Faster way to keep your focus without closing VS at all is to simply *CTRL+SHIFT+P > Reload Window* This ensures you can keep flowing with minimal hiccups.

Will their be other episodes or do you prefer to wait for a more stable release ? I guess life happens too, but still, it's a great tutorial series, too bad it had to end here like many other...

amazing tutorial, your learned me so much

You don't need to set the player and camera to half of window dimensions, you can just set all coordinates to 0. Of course if you don't want the camera and player aligned, e.g. if you want the player to be in the 25% from the left, then you indeed need to use window dimensions (but the positions won't update upon resizing the window).

Another approach to pause simulation is to create a system `transition_to_paused_simulation` and then schedule like `OnExit(AppState::Game, transition_to_paused_simulation)`, this way if we have more ways to go to main menu the simulation will still pause.

I tried to create a component called Ball and add to both player and enemy so I can implement a single system called confine_ball_movement, for some reason the query never found the balls. Another way to fix the bug is to fix the position of the enemies on spawn as once they are created they will never cross the limits

Why do you add global variables and not put them in structs?

This a very complex programming language

new hello world code: use bevy::prelude::*; fn main() { App::new().add_systems(Update, hello_world_system).run(); } fn hello_world_system() { println!("hello world"); }

Just a note on spawning stars overtime: `timer.just_finished()` may be better choice to be used for Rust 1.79.0 & bevy 0.13.2 (2024), since what we need are trigger for when the timer is just finished. But since it behave identically with `timer.finished()` on a repeating timer, I wouldn't say the video is wrong. Just more in readability aspect IMHO. Amazing tutorial by the way!

Oh noo - it's over..? 😢 Thanks a lot for this excellent series!

Thanks for this gem! Another set of building blocks in place. This was easier than I expected

Ecs is awesome. Soo easy to extend. I'm glad I found your tutorial series, since I was creating a mess. Looking forward to the cleanup tomorrow with the new knowledge.

I really like how you extend the functionality of the game over time. This shows how well you can extend an ecs codebase. Looking forward to experimenting with it!

Great tutorial! Well paced and easy to understand. ECS felt very natural to me for some reason and I didn't know why. Your example with the sql table made it click.

First of all thank you so much for this amazing tutorial! It really helped me a lot! I found a bug in the UI for Ep10 where if the GameOver event is cleared before the GameOverMenu is up and running the Final Score will not update. I made a pr with a fix I found using manual event clearing. If you have the chance, please consider reviewing it.

In your transform, why didn't you query for a Transform With Enemy?

I like this tutorial, though It's quite difficult for me to tell if what you're coding is a Bevy construct or if what you're coding is a helper that's unrelated to Bevy.

me and my homies hate bevy UI (I still don't know how to Center text without jank ahh methods, I'm just praying for a gui editor for it soon)

I am getting a weird issue where my video output renders for what I assume is one frame and then goes back to black? using bevy 0.13.0, with the z value of the camera set to 1, both the spawn camera and spawn player are in an add systems set to startup, it's giving a warning saying "couldn't get swap chain texture. this often happens with the Nvidia 550 driver. it can be safely ignored" incase that's significant. also I am on Wayland. very confused why it is rendering the output for a frame and then just back to a black screen. I don't think this is an issue with me forgetting something because the bevy example breakout game also renders a single frame and then goes black.. any ideas what might be up? edit: btw my gpu is a gtx 1650 incase there's something to do with that edit 2: I checked discord for someone else with this issue, they said resizing window fixes it (it does), why is that even happening???

Thanks for the great tutorial!🤩

Sorry dude I couldn't concentrate over the sound of that keyboard. I mean HOLY SHIT it sounds good. What switches are you running in there?

For those coming from Bevy 0.13 .iter does not work on events, you need to use .read

So far, very good!

Me every time that I start a video "What's his name again". You "Hi, my name is Jacques"

Really liking this tutorial series. You have a very easy going voice and instruction. Very cool. Thanks.

This was the most crunchy episode so far but it is so important. Thank you for making learning crates and managing a project so easy. This is a level up even for my non-gamedev rust projects.

2:15 `keyboard_input: Res<ButtonInput<KeyCode>>` now

9:50 now is `add_systems(Startup, hello_world)`
