Is there some kind of easy way to make a tilemap out of an existing zone's assets?

I want to add an already existing zone to my project but I have no clue how I could import all of the chunks into godot.

If you mean you wanna add a zone like Green Hill or Chemical Plant etc, then.. I don't think it's really a Godot or SWN problem or anything, you just download a tileset of the zone you want from the spriters resource or smth, then put it in your project's folder, then the rest is just how to make a level layout or how to use tilemap layers in Godot, which is smth you can learn either by yourself or through tutorials on Youtube.. (also I specifically said Tilemap Layers cuz the Tilemap node is deprecated as of Godot 4.3 afaik)

If you didn't care what order the tilemap ended up in you could probably write/generate a quick script to get tilemap data from soned and convert that all to a technically usuable map of 16x16 tiles with collision already made. I don't parsonally have a script like that already and I probably wouldn't use it if I did because I like my tilemaps to look like the pieces of a level that I plan to make with them rather than to optimize them for minimal 16x16 tile re-use.

If you either don't have the gumption to make such a script or else are like me and care more about your tilemap looking nice and being easy to pick shapes and place tiles with than saving time laying out collision, you are going to have to do it the hard way.

You could always be the change you want to see by starting up a repository of just tilemaps for classic Sonic levels. I don't think we're going to do that for this project. If you do make such a project I'd be happy to include a reference to it in our project's documentation.

yeah i ended up just doing it manually, it is annoying remaking every single chunk but its better in the long run

Unfortunately, what you ended up doing is basically the process. I had to do this countless times for Sonic 2 Retold and while you can do some things to speed up the process like exported blocks (if you're using SonLvl to export the level parts) and exported them as an animation in Aseprite, there's still a ton of actual work that goes into it. Look at Emerald Hill Zone in Sonic World's Next; the tilemap there is based from the same one from Sonic 2: Retold.

the one thing that I've been having trouble with more is collision
a lot of the collision is kinda messed up

[Caverns4]

That's the unfortunate part. The classic Sonic games use pixel masks for their collision angles, and Godot uses collision shapes.
In order to get something as close as possible, you're going to just have to use some duplication. You'll pretty much have to tweak the collision polygons yourself and find happy mediums in spots, 1:1 copies aren't very feasible.
You'll pretty much have to make peace with the fact that you can't make something identical, just very close if you're lucky.

I personally just feel like Godot's tile collision editor could really benefit by making numerical entry possible for the vertex positions. You can still do it that way by editing the text files by hand, but who wants to do that?
