Any confused about why you're getting an error for the 'Input' resource. In Bevy 0.13, the Input resource was renamed to `ButtonInput`. Additionally, instead of the KeyCode being `KeyCode::W` it is now `KeyCode::KeyW`
Immense thanks for keeping it up with bevy's nurture phase. I'm glad you treat your video series independently, starting from the ground up and improving the fomula every step of the way. It could be easier for you to defer us to a video you made a year ago, but instead you explain it better than ever, again, and again. That is commitment and I'm sure you're extremely proud of it
You're doing the lords work. Are there any plans to show case 3d game development? Most big game engines have tutorials on creating simple RPG's for them, it would be super sweet if bevy had the same. I can't think of a dev more suited to lead the charge!
i cant even express how hyped i am for this. i just finished coding for tonight in bevy , your series thought me so much. keep going and make more! p.s i would really enjoy a series about making a first person shooter in bevy
I've started learning game development with Bevy these days. It's quite a dream for me and with Rust and this engine things seems to be to good! I will watch every single video from this series! Thanks!
I started, stopped, re-started, stopped and finally re-started learning Rust!! This seems like an interesting series to get some coding experience in Rust. Looking forward to more.
I had never heard about Bevy before or cared much about game development, but this tutorial is so simple and nice that I decided to follow it. I like Rust a lot and this is a nice way to learn more about it while having fun. Thanks a lot, you are great!
@@logicprojects Its a very common mistake that triggers me because I speak french and it means "red" which is means "red-like" so it always gets me when I see this typo lol
for anybody being confused with the `_` keyword in the iteration of tuple in the Query system, it is a wildcard pattern that can match any value and is often the returned value will be ignored in the range-based for loop. In this context the second item of the tuple will be ignored, i.e the Sprite object will not be processed in the for loop.
Appreciate the tutorial. Bevy's been one of those things I've wanted to learn for a while. I know the controller isn't the focus of the tutorial at this stage, or anything, but my immediate thought on seeing it was some boolean maths to turn 4 if statements into 0, but my understanding of Rust is still developing. so it's looking like: transform.translation.x += 100.0 * (input.pressed(KeyCode::D) as i32 - input.pressed(KeyCode::A) as i32) as f32 * time.delta_seconds(); transform.translation.y += 100.0 * (input.pressed(KeyCode::W) as i32 - input.pressed(KeyCode::S) as i32) as f32 * time.delta_seconds(); Which is a little less elegant than I saw it in my head.
I would look at the leafwing input manager plugin. It's made by core bevy developers and wraps over Bevy's default input with more high level things. It makes supporting keyboard and controllers easier
I do something like this (and I prefer it) but I can't say it's objectively an improvement: if !input.any_pressed([KeyCode::W, KeyCode::S, KeyCode::A, KeyCode::D]) { return; } let up = input.pressed(KeyCode::W).then_some(1.0).unwrap_or_default(); let down = input .pressed(KeyCode::S) .then_some(-1.0) .unwrap_or_default(); let left = input .pressed(KeyCode::A) .then_some(-1.0) .unwrap_or_default(); let right = input.pressed(KeyCode::D).then_some(1.0).unwrap_or_default(); let translation = Vec2::new(left + right, up + down); for mut transform in query.iter_mut() { transform.translation += translation.extend(0.0) * time.delta_seconds() * 50.0; }
Depends what you mean by "advanced". The bevy docs are the primary documentation for bevy. You also can look into the source of the engine itself at a certain point because it uses the same concepts as normal bevy apps. My recent rendering video is also a relatively advanced video that deep dives into rendering internals. For really advanced things you probably want to ask the developers directly. Also reading plugins written by engine contributors is a great way to learn how they solve problems.
i really wanted to use bevy before but there is one thing that keeps me away EDIT: alright let's go, learn bevy, fck unity just gonna fork it and name the branch "master"
Really great introduction to Bevy! I think this series is gonna be awesome. May I suggest putting some clips or screenshots of the bevy window (or terminal) after each code snippet? It would change the pace of the video but I think it would be helpful to see what impact each code snippet has on the program.
I plan on doing that as we go on. For this part the changes were black screen to grey screen so I didn't feel like it added too much but when there's actually a game to show I will!
Great video. I have a question though. In the character movement, in the for loop why did you put &Mut characters when characters is already Mut? Sorry about the question but I'm a completely beginner in rust
That is syntactic sugar over calling characters.iter_mut(). We still need to tell rust it's a mutating iteration and rust is repetitive with it's muts. You could also do &characters for nonmutating. If you miss a mut the compiler will tell you though!
It's a really useful tutorial, thank you ! I was just diving into Bevy when I saw this, I think it will help me a lot, I like your way of explaining ECS concepts, it looks a lot easier than what I thought !
I tried to include the authors info. They are from unity docs about their ECS but I think they retired them because the animations really didnt have anything to do with ecs
Awesome video! I was really struggling to learn Bevy and I was getting upset because ECS is something really new to me. I was almost giving, but then I saw this video and now I can continue learning.
Hello, great tutorial as always, but could you make screenshots fill whole screen or make frame with less contrast color (e.g black to match the code editor) in future videos, please? It’s a bit harsh for the eyes, especially when watching in the dark.
In your query in the character_movement system you are getting immutable access to the Sprite component, does it not make more sense to use With instead as we are not using the Sprite? edit: I can see that in part two you are switching it to the Player component and then accessing the speed value, so it makes sense.
Question: Do I need to place to Bevy folder - into the same - "cargo new myGame" folder" ? Where does the Bevy folder need to be placed to "talk" to the myGame Rust files? LOL! I hope this makes sense!
So rust is smart. Once you install cargo and use it to create a project it will make a cargo.toml file in a folder. That file being there is all rust needs to know it's a rust project and to use bevy. The rust book should get you set up and running a project and then it will make a lot of sense
@@logicprojects - I'm new to your channel. Do you have a link post to the Rust book? I developing on a Raspberry Pi 3 B+ with VIM as my code editor. I got use to VIM during my intro to prgrammng... It's strange... I tried to learn C# ,(and the built in languages,) with Unity, GameMaker, ClickTeam Fusion ,(on my Windows 11 PC,) but for some reason game engines messes my thinking up. I found engines harder to learn - wasted time digging around - trying to find everything. I know everyone has their own work flow LOL!!! So, it's me... Rust/ Bevy seems really awesome and look forward developing a game in it! I also like the Cargo compiler.. it seems to catch everything - on the front end.
Here is the Rust book: doc.rust-lang.org/book/ it should get you set up and started with Rust. Cargo is magical and it's a great experience to work with! I also used to use Vim and I use the Vim plugin for everything
