You're not using Godot to its potential

In this video, I talk about making component-like structures in Godot, which I feel is often overlooked.
Yes, GDScript is object oriented, but we have such a powerful tool (nodes) at our hands, we might as well use it to its fullest!
Using nodes as components is so much more flexible than rigid OOP inheritance trees.
Of course, if you over-do it, you'll just be shooting yourself in the foot; ideally you'd want a healthy mixture of both. That's why Godot is so great!

[@ykyjohn]

Thank you

[@Entikai]

I think you are mixing up two terms. Composition over inheritance and Entity Component System.

[@quickgaming2466]

Or ECS falls under composition umbrella, so he skipped right to it.

[@NihongoWakannai]

"The problem with OOP" you listed problems with deep inheritance, which is not a necessary part of OOP. This is not the '90s anymore, components and interfaces have been the standard for OOP for a long time. "Composition over Inheritance" (which is the concept you described here) was mentioned in the book "Design Patterns: Elements of Reusable Object-Oriented Software" back in 1994. As you can tell from the title of the book, composition/components are a technique of OOP. "ECSs" You're not describing ECS, you're just describing components. You're using OOP with components, this is not ECS. Unity functions in the exact same way with built-in components as part of the engine, and it is OOP. ECS is mainly about optimizing the update loop so that similar things are grouped together which reduces CPU cache misses. A common misconception is that ECS is just "a system with entities and components" but an Entity, a Component and a System are three separate things which have specific uses within the paradigm of ECS. You can do regular OOP with entities and components. One talk I would recommend is "Bob Nystrom - Is There More to Game Architecture than ECS?" which discusses the misunderstanding of what ECS is and how to instead implement well structured OOP architecture. You can also look up "Game Programming Patterns" by Bob Nystrom which is free online and explains a bunch of different programming patterns which you can use to solve issues with game architecture.

[@bonniezo_]

Ahaha i was just gonna write about this, i love OOP and one of my pet peeves is when people look down on OOP just because of deep inheritnace, which is not even a problem anymore as literally every material on OOP says use composition on a "Has a" relationship and use inheritance on a "Is A" relationships. Example - A car "has a" wheel(s) vs a car "is a" vehicle. A car here would inherit from a vehicle class, but be composed of wheels

[@rmt3589]

I was gonna say how I would have pushable be a child of the gridobject script, and interactable be its own script, and attach both. But this is way more fleshed out.

[@Dxpress_]

Aye. As soon as the video mentioned "let's have everything inherit GridObject", I already knew this was just going to be the age-old composition vs. inheritance discussion again. It's good for people getting started with _learning programming_ in general, but it's not something specific to _learning Godot._

[@tiagocosta6074]

Was going to say the same thing. Starting the video I was just thinking "I learn this back in 1996 when I first started dabbling in C++!. Surely this can't be a new thing again. And don't call me Shirley!"

[@boccobadz]

Doesn't change the fact that OOP is just a bad concept which works great in simple examples but falls miserable and creates unmaintanable mess with anything even remotely complex.

[@lufog]

[@ryanmckenzie5918]

This is very helpful! I have to say -- I really love the presentation in this video. I've recently been very interested in storytelling in things like teaching/marketing, etc., and this is one of the best examples of practical storytelling I've seen in a programming video for some time, compared to the myriad "hey guys, here's how you do the thing" presentations. This was super engaging.

[@justaway_of_the_samurai]

Instead of using child nodes, you could create instances of the component classes on the parent class in-code. This can simplify the tree structure so it isn't cluttered visually. Perhaps you could have one single EntityComponentSystem class that all classes inherit from, and which includes the logic for attaching child components to new parent classes using factories, and also invokes the frame-by-frame processing logic for each of the child components so that each child component is guaranteed to be invoked during regular processing or some other events.

[@spiralhalo]

I wouldn't invent a whole new system if the engine's built-in works just fine. Less maintenance fee and kinda the whole point of using an engine. I agree child nodes isn't a requirement in a way, but it's just a clutter of tree vs inspector if you need exported variables. Could also group all the script components in a single node and hide it away.

[@Robot257onlinehue]

The thing about this approach that everyone keeps talking about, is that if you want to make a DataType (ie: an enemy, boss, item, etc) that's slightly more complex than the rest, you'd have to make another node with another new script to implement that functionality... And then later on add another one for that particular functionality of that particular DataType, and so on until you have a bunch enemy nodes on screen with 10 component nodes each with it's separate instances of those scripts (and in Gdscript at that, which is not optimized for this) during runtime. To hammer it in more clearly, this is a very CPU-taxing way of implement common and unique functionality. What I usually do if you're wondering, is just make a C# script for every DataType I want to add to my game (usually enemies or items), and make them inherit some interfaces for common functionality. Then if I want to add unique functionality to that particular DataType, I just have to change the script attached to it instead of adding another script. With this setup instead of having thousands nodes with tens of thousands of script instances, you get a few dozens nodes with more-or-less the same amount of script instances. Good video though, just saying this cuz I keep seeing people w this exact same setup and complaining it runs poorly

[@ClockworkGearhead]

In other words: good for small games, not for big.

[@635574]

True there is a big difference in how this scales

[@NihongoWakannai]

@@ClockworkGearhead It's not about the size, but about the functionality. If you're making a game where lots of functionality needs to be interchanged regularly, then modular design is great. But if you're just making a platformer or something, it's very over-engineered and a waste of time.

I did something similar to this in my game where I have an enum that tells effects when they should happen in battle. These timings get applied when the effects are initialized. The function that gets passed into the constructor will execute when the listed time comes, so ONTURN will execute on turn and ONATTACK will execute when the entity attacks. I also paired this with ONWHOM which basically says which party it’s going to act on. It’s a neat little thing and I have yet to finish all the 11 different timings but I think it’s something that’s worth while, especially for differentiating between poison, burn, and bleed.

[@SnakeEngine]

One thing that people get consistently wrong is that OOP is not about inheritance. Inheritance is just a tool to save duplicating code (and a crappy crutch to achieve limited form of polymorphism). The structure of OOP is really just the one of encapsulated organs talking to each other by emitting signals (and it's obvious that a different organ can react differently to the same signal, so the idea of polymophism becomes self-explanatory and general). Just don't use inheritance if it prevents you to achieve that goal. Modular Components is also a perfectly valid way to achieve that. Hope it helps :)

[@mikelodo5792]

I've been using a system for my PVZ inspired game where there is a giant "Machine" (Like plants in PVZ) script that has an array called "Properties". Depending on the properties listed in the array, the script has certain behaviors. But as you mentioned in the video, this means that all machines have a lot of wasted code and I didn't really think about this. On the other hand, Machines can any number of properties. So I'm wondering, is listing them all as nodes attached to the game object more or less convenient then just having a shared machine script with individual "if properties.has(*specific property*)" conditions??

[@Spartan322]

The usual manner to do things in OOP without deep inheritance for everything is using Mixins, basically taking the idea of the inheritance and making them into ingredients which you can mix together to get combined behavior in the class. (Godot doesn't inherently support Mixins out of the box, but emulating the behavior in Godot is not hard)

TLDR: "Composition over Inheritance"

[@coldchange]

Hey, just found your channel and really found this advice quite useful. I have used these techniques once or twice, but never really knew when to use it, since my purposes were rather niche. However, the way you explained really is eye opening on how this method is distinct in its purpose from inheritances and such. Also quick question: Are your songs free to use in personal or commercial projects? Music is an area I am limited in, and I absolutely love the vibes of the songs on your channel!

[@lshadowSFX]

Regardless of all the techy definitions crap, it's such an interesting approach!!

[@kevinfischer4869]

1:06 what exactly makes the parameters/methods useless? I worked on a puzzle game where I used the technique you described; every puzzle item derived from the same type and I simply configured its settings differently to enable or disable different traits. One of the benefits of this approach is its ability to allow me to transform state really easily; when a wood block is disintegrated by a fire ball, I simply switch canPush to off. How would your system handle this? Would it not entail adding/removing components? Surely this would be more difficult to manage.

[@BlackFenix-jz5rs]

Hmm, so from what i understood, roblox studio is also ECS and OOP?

[@dimanarinull9122]

[@magikarpusedsplash8881]

[@saveriov.p.7725]

Thanks. I was going nuts making a sword in my game about guns. Sword needed the methods used by weapons, but also damage methods used by bullets. "Sword is a bullet that can be fired" was how I got it working for a while. I changed it so that there's a "damage component" which contains all the methods for damage. However, now every single bullet needs a "damage component" since this isnt part of the base logic. Is there any way to improve this?

[@neworderseo]

Lazy gamedev: Just fire a big invisible non-moving bullet from your sword.

[@Omnicypher001]

for an ECS, you probably want a dictionary of named strings, where each character in the string represents a component. then you can spawn those in by parsing the string, and adding the component trait data to various global arrays, that are used in systems that update specific traits in those components. Each spawned in component, would get a unique ID, and that is the index location the traits are stored in the arrays. The global arrays group similar traits for faster processing, which is efficient for large simulations because it reduces branching code.

[@bbrainstormer2036]

It is worth noting that ECS isn't just the use of modular components. It also focuses on separating the data (the components) from the logic (systems), which your system does not do. Also, other people have mentioned this, but your annoyance is with deep inheritance, not OOP. Godot _is_ object oriented, which makes it all the more annoying that GDScript is missing some very important object-oriented features, like generics and interfaces

[@igork1336]

WOW I've just come up to the same way of implementation for my game 24 H ago. And I've received the video in youtube recommendation which describes the same topic, which was posted 21 H ago. KZbin recommendation algorithms are scary.... Thank you =)

[@pigdev]

I didn't get the description "GDScript is object oriented, but we have such a powerful tool (nodes)[...]". Components and Inheritance are not opposite approaches, on the very contrary, they are complementary approaches. We use inheritance all the time in Godot to extend component's behaviors, for instance.

[@brainstink]

That is amazing and I’ll totally be implementing that! But I do have a question, how could this solve the fire + life-steal bullet problem? If a fire bullet has one animation for the bullet, and the life-steal has another animation, then how do you make a combination of animations? If components are completely independent of each other, they can’t have their own “fire + life-steal” animation, right?

[@pixels_per_minute]

I'm probably wrong, but wouldn't you use an animation tree to set up custom animations for each situation? Unless you mean just spawning multiple different particles in the same place, which you should be able to do through code.

[@starfart69]

This video deserves more views. YT algo do your thing.

[@GodotNoContext]

There's an unofficial extension for Godot called Godex which adds support for ECS as a subsystem. You'd have to compile the engine from the source though. All of this signifies that while Godot may imitate ECS, it cannot fully embody it. If you find yourself in this situation, consider switching to an engine that is built on ECS principles from the ground up. Doing so could save you from a lot of frustration.

Good point you rise here! Although as others said, this is not an OOP issue, but the @ss programming languages deficiency. This wouldn't happen if we had multiple inheritance like in C++. I've faced this issue a million times, and yes, you end up changing your design, or working around it. What you show is really cool for some scenarios. BUT, your classes need to adapt to the common functionality and the executed code will be exactly the same for all of them (so you'll need a very good design if you want variations). Regarding some cases you showed, there may be ways of achieving that with patterns such as decorator for example, but it's definitely a flaw of the programming languages that should have already been addressed. Your way in Godot is a very good option!

[@braingrunt5499]

what does the & symbol mean in the context of owner.set_meta(&"InteractableComponent', self)

[@tienne_k]

The & symbol is used to denote that the string "InteractableComponent" is a StringName instead of a regular String. It's a shorthand for: StringName("InteractableComponent") What are StringNames? StringNames are like Strings but way faster and less flexible, which makes them good for stuff like IDs. Unlike Strings, two StringNames with the same value are -- to the engine -- the same object. For example, when you compare 2 Strings, you'd normally have to go character by character and check if they're the same. Well, since 2 StringNames with the same value are the same object, the engine can just check if the memory location are the same. This makes comparing them really fast (especially for long strings)! The downside is that it's slower to mutate (e.g. join 2 StringNames or add characters) because Godot has to create a new String first.

[@natthapolmaneechote1218]

I'm a bit confused like why should we use the node to store script???? Why don't we just implement some customs Resource and used it as component for the main node??? Is it's to avoid having too the env var to keep the Resource??? But that still doesn't make sense caz we can just have the ArrayOf as an component for the Entity. I think I don't understand the fundamental different between two approach. Can you explain me a bit further??

[@tienne_k]

Good point! You could also do that. The main difference between the two approaches is that Node-based components can *directly* interact with the scene tree, while Resource-based ones can't. For example, in the Resource based approach, you'd have to always keep a reference to the parent node (the Node that has the component) or the scene tree if you want to interact with them. Compare that to Nodes where you just have methods like `get_tree()`, `get_node()`, `create_tween()`, `_process()`, etc.. right at your fingertips when you need them. The other advantage of using Nodes is that you can easily add, configure them in the editor. For example, you could have a component which extends `Node2D` or `Label`. Then, you could position them as you wish in the editor! E.g. changing the position of the `Node2D`, or setting the text on the `Label` But yeah, you could totally just have something like `@export var components: Array[Component]` if that's more convenient for you I hope this helps!

No, because with interfaces you would need to rewrite the methods for each class. This way you don't have to, but it's tricky, as all your classes will share exactly the same behavior (in many cases not likely). It's something in between a composition and a multiple inheritance... kinda.
