learn-gdscript VS eigen

When I see someone wanting to start out and knowing nothing at all I do not point them at the 20 games challenge. I first point them at something like this: GDquest GDscript for total beginners . It at least attempts to teach some absolute basics as well as abstracting/hiding away useless and confusing framework you really don't want to be occupied with when learning from zero. But it's also guilty of assuming knowledge in some areas. That is sadly unavoidable. It also teaches almost nothing about object oriented design. (Something that should be looked up if you're working in an engine that has this as it's central design philosophy)

You can use this to learn GDScript https://gdquest.github.io/learn-gdscript/

Do you have any experience with programming? If not, you may want to start here https://gdquest.github.io/learn-gdscript/

If you have never done basic fundamental programming you can begin with https://gdquest.github.io/learn-gdscript/ , while this still hasn't been updated to Godot 4.0, it is universal enough not to be a problem.

Is Eigen still alive? There's been no release in 3 years, and no news about it: https://gitlab.com/libeigen/eigen/-/issues/2699

I was curious about these libraries a few weeks ago and did some searching. Is there one that's got a clearly dominating set of users or contributors?

I don't know what a good way to compare these might be, other than perhaps activity/contributor count.

I am trying to include Eigen in my project via FetchContent. They define/assume-defined PROJECT_IS_TOP_LEVEL on line 19 and, among other locations, on line 607 in their top level list file.

Eigen is a header-only library, thus simply cloning it from the official repository into the FOGGDD folder should be enough.

math library because you should never implement a math library yourself, and you probably want somethign more focused on performance than STL. GLM may work if you just need basic vector support. Eigen may help for a more physics heavy game. But I'd probably find something in-between those two

cmake_minimum_required(VERSION 3.15) project(app) include(FetchContent) FetchContent_Declare(Eigen3 URL https://gitlab.com/libeigen/eigen/-/archive/3.4.0/eigen-3.4.0.tar.gz) FetchContent_MakeAvailable(Eigen3) add_executable(app main.cpp) target_link_libraries(app Eigen3::Eigen)

Today was very easy to do with Eigen
