Hi! I've been wanting to create a similar mod since the release of Space Age, but it's great to see someone else do it! I noticed (while casually downloading the mod and viewing the code) that the mod references Space Age prototype definitions (like asteroids) in plant.lua (likely a misspelling of planet.lua, you should fix that too) and even the core mod, without depending on them in info.json.
Instead, replace the dependencies line with this:

"dependencies": ["base >= 2.0", "space-age"],

It's always good practice to depend on the base mod, even if you aren't directly referencing or modifying it's prototypes.

OK, thanks

Welcome to collaborate on development or make any suggestions

The above mentioned issues have been updated. In addition, the mod details page has also been updated

https://github.com/PlexPt/small-factorio-mods

The section I currently need the most assistance with is data/planet-map-gen.lua.

Ah, ok.
PR created to implement more... realistic surface generation for solid objects (such as pluto and mercury) which closely relates to in-game surface generation.

great
Do you have a discord?

I think you forgot to include Space Age in the dependencies:

Failed to load mods: __real-starry-universe__/data/planet.lua:2: Path __space-age__/prototypes/planet/asteroid-spawn-definitions.lua does not match any enabled mod.
stack traceback:

    [C]: in function 'require'
    __real-starry-universe__/data.lua:1: in main chunk

Mods to be disabled:
• real-starry-universe (1.0.4)

Of course, it would be nice if it could be played without Space Age, but I'm not sure how hard that is.

I accidentally covered it.

no.

We need to exchange ideas quickly. What chat tools do you use?

Github, the forums and here. (as in mod portal discussion page)

OK , As this repository requires collaboration and this mod is no longer small, I think it might need a separate repository.
