ecs-faq VS ygopro

The Wikipedia article provides a broad overview, while this FAQ offers a more systematic exploration: https://github.com/SanderMertens/ecs-faq

Sparsey is an Entity Component System focused on flexibility, conciseness and providing features exclusive to its sparse set-based implementation.

For further reading, here is a great article about these different approaches within Rust specifically: https://csherratt.github.io/blog/posts/specs-and-legion/ and here is a great general resource for commonly-used terms and techniques in ECS development: https://github.com/SanderMertens/ecs-faq

Godot has a node based system (nodes can have child nodes linked to them, and there are different types of nodes for the type of functionality they represent). Another alternative could be a more OOP approach (utilising inheritance as the main means of extending functionality), not aware of any modern engines that take this approach anymore. It’s also worth noting that ECS implementations can differ wildly, this faq from the flecs creator has a good rundown on what some of different variants are.

You might wanna take a look at https://github.com/SanderMertens/ecs-faq, it lays this all out better than I can.

Using the relational model for app data in memory is really interesting.

Martin Fowler wrote about doing that as a way to get around the "object-relational mismatch" issue[1]. Richard Fabian describes "data-oriented design" as having a lot of overlap with the relational model[2]. ECSes becoming very popular in game engines are basically in-memory relational databases where "components" are "tables"[3].

This is the ECS FAQ I'm currently using.

While Unity's DOTS/ECS is positioned as solving performance issues for large numbers of objects, there are a number of other advantages. See https://github.com/SanderMertens/ecs-faq for a more in-depth look. IMHO the reusability and extensibility ECS encourages is as valuable as any performance increase. Compared to the GameObject style, which encourages random state mutations and side-effects, ECS enforces a more functional style, which results in code that is easier to reason about and test.

thanks, i think a little more background on the ECS world will help you get the context, this is from the author of Flecs: https://github.com/SanderMertens/ecs-faq

Omega actually has fixed more problems and rulings than ygopro because they changed the core. You see, there were some ruling interactions that could not be fixed by just changing the script. It required a core change and very few people beyond the team that created ygopro (Fluorohydride), know how to change the core. Edopro is a fork of the ygopro that is translated to English and maintained. If you don't believe me, check here: https://github.com/Fluorohydride/ygopro/issues/2321 Case 6, 7, 9, 10, 11, 12, and 15 will fail on edopro. This is because in order to fix 10-12, the order of operations of how damage calculation has to be changed in the core. This order of operations was correct years ago but was changed by OCG later, so the core is outdated and nobody cares enough for these niche scenarios to fix it because they are too rare.
