Thanks for checking out the mod!
How large are the blueprints you can accommodate?
Currently the mod works with blueprints up to 32x32 tiles. It could be expanded to be larger but we'd risk overlapping ruins.
Can you create "destroyed remnants" as seen in level 5 of the factorio tutorial?
The mod creates blueprints by code that works out how much of the blueprint to place down between 0% and 100%. There is also some logic to make it that not every chunk will have a ruin and distance from spawn also has an influence. In the future we will investigate placing down remnants, but it's not a feature that's currently implemented.
How many blueprints can you store in your mod?
In theory infinite, or as many as you can store in a factorio blueprint book. In truth it will be limited by the download size as the bigger the mod is the longer everything will take to load/download.
Can you create trees?
Not currently possible that we're aware of via the blueprint system this mod uses. You'll need to clarify further what it is you want to achieve.
Can you make chests full of items?
Yes, but currently not implemented in any way within the mod.
Have you replicated the behavior of hostile defences?
Yes this has been done and will appear in an upcoming release so your new easy to find equipment might come with a little more 'bite'.
Did you really make this from scratch?
Yes, not long after "The ruins mod" came out we discovered it when we started a play through. We liked the concept but it's scope was unfortunately a little lacking. We wanted to work on remaking it and only now recently found the time to do so.
Unfortunately I cannot really help with your mod since I do not know lua...
I'm not keen on Lua, so this mod is written in typescript and transpiled down to Lua at build time. The mod is open source and the code is avaliable on GitHub.
I would be thrilled to create ruin blueprints for your approval should you require more.
We are happy to welcome blueprint ideas, please do so using the link at the mods github page - https://github.com/TGNThump/AbandonedRuins - it's right at the bottom. You'll need a GitHub account to do that.
