In this video we look at Inheritance vs Composition and a scenario where Composition is preferable in Godot 4.
Both Inheritance and Composition have their pros and cons, but Inheritance is for more often taught, despite Composition being very important in Game Development. I recently ran into Composition in my own projects and felt that it was vastly underrated and deserved to be taught.

I love that you managed to explain a fairly confusing and complicated topic with examples showing both the problem and the solution by using this approach and also the tradeoff for using the inheritance over composition ( at least for this kind of scenario ). I think those are the kind of educational videos that are hard to come by, especially with an easy to follow visual representation, which are really appreciated by the community. We know it's not easy and it takes time to find examples and then explain them in a simpler manner, as you did, but we really appreciate each one of them and we thank you for that!

@fishybusiness1149 Год назад

This man really spoke for all of us and nailed it

@HoovyMcBoovy Год назад

I agree, thank you for going into examples that are very applicable. Here and there I'll watch some coding videos that give useful advice, but they don't provide any examples and I have no idea what to do with their advice because I have to spend extra time figuring out what it means and how to apply it.

@HisBelovedSon70x7 8 месяцев назад

Amen! As I was watching I thought to myself I need to compliment this man's fantastic teaching ability. Then I scrolled down and found you've done it better than I could have. Well said. Bitlytic thank you for such a clear and simple explanation of the different concepts and providing an example, you made it very easy to understand and follow.

@fkeyzuwu Год назад

cool video! if you are already trying to decouple code using composition over inheritence, i would probably create a signal on the hitbox that the parent object would connect to. then whenever the hitbox gets hit, it emits the signal, the parent can then decide what to do with it. in this case propogate the attack info onto the health component. this way the hitbox component does not need to know anything about the health component.

@Bitlytic Год назад

Very much agree, signals and composition work so well together but I figured I had already given enough fundamental info in the video or I would've included that. Specifically I would've replaced the queue_free in HealthComponent with a signal emission that the player can choose to use or not

@BrochetteBoeufFromage Год назад

How can i emit a signal, is it get_parent().die() for example or am i missing the point?

@BrochetteBoeufFromage Год назад

Because if it's what i wrote, you have to declare a die() function for every object

@cyberneticsquid Год назад

@@BrochetteBoeufFromage I'm not really sure how to explain the signal system just in a RU-vid comment, but I recommend checking the Godot documentation, it explains signals really well

@catcactus1234 Год назад

@@BrochetteBoeufFromageYou don’t need to use a parent for signal emissions. You just need an acccessuble entity to connect to. Many godot tutorials use a “global” or “manager” script that contains their most common functions / signals which they can emit to from any script or object.

@computersciencestudentriverbat Год назад

Composition as a design pattern I think is uniquely equipped for solving problems and making more robust (and easier to maintain) code. There aren't a lot of videos on programming patterns in Godot and seeing this is great. Talking about general/generic problem solving I think helps beginners out a lot by helping us step outside of "How to do X" to thinking about breakdown solutions to fit their own needs/program. Tutorials have their place and purpose of course, but I think Godot (programming in general to be honest) is in great need of this sort of problem solving/design thinking sort of information. Great video!

@poleve5409 18 дней назад

as much as I love making pretty and readable code… we have to admit it honestly doesn’t matter for 99% of godot games

This has to be one of the most (if not the most) approachable explanation of inheritance vs. composition. Very easy, straight forward and clear. I had to learn it the hard way and for the longest time couldn't understand the advantage. I wish I had this video back then. Love it!

@PamellaCardoso-pp5tr 6 месяцев назад

@@kurushimee they actually do. Spaghetti code leans into massive super classes bloated with a lot of functions and huge objects that aren't properly managed in the memory by the program. So, even tho they aren't automatically making your code laggy or bloated, the usage of inharitance leans into this kind of problem really easily and it gets really hard to manage the memory usage of such objects.

@patek2385 Месяц назад

If you would use scriptable objects you would be golden

@lunaticwyrm4675 10 месяцев назад

When I develop in Godot, I often use a mixture between inheritance and composition, and oftentimes, I use resources instead of nodes for composition since it is easier to modify through an export statement. For example, I have a slew of statemachine resources that I can plug in to my Actor class (which is basically an entity class), which makes it easier to trade behaviors depending on the entity type and whether there is currently a cutscene or battle.

@da_roachdogjr 10 месяцев назад

I kind of got deeper into godot recently and I'm using custom resources unaware of this video's specific subject. I find it very weird that custom resources aren't being heavily promoted by tutorials. Need the same enemy to have different types of stats or damage, just drag and drop. It's like secret godot magic because there's only like 3 decent videos about it. What going on? I ctrl+F and this is the only comment talking about resources O.O

@lunaticwyrm4675 10 месяцев назад

@Pulse_Skeleton Yeah Ik, weird right? You'd expect this miracle solution to be talked about more. It's so useful for, say, making multiple unique character objects in game from the same Actor scene without having to make seperate actor-inherited scenes for each character.

Hey, you did excellent explaining the difference between Inheritance and Composition. Not a lot of videos take the time to utilize simple illustrations (and color coding elements such as Attack, Health, and Hitbox). Very helpful for visual learners. You're on the right track, and I hope you keep making videos. That said, I'll be sending this video to my aspiring game-dev friends when I see them inevitably copy/paste code. Also, that sprite animation at the end is super cute!

Very helpful, this is the way. I've never really been a fan of Inheritance patterns for the same reasons you stated where base classes often do too much, and moving that functionality somewhere else is a huge pain.
