im not sure if this is a "how they do it" issue, or something elts, but this is the error im getting

error is --zzz-claustorephobic--/data-final-fixes.lua181: attempt to perform arithmetic on field 'additional_richness' (a string value)
--zzz-claustorephobic--/data-final-fixes.lua181: in main chunk

link to conflicting mod as that might help with finding it for the conflict list or testing: https://mods.factorio.com/mod/bzlead

i forgot to add im on latest stable, and have latest of both mods involved.

edit: this should have been under bugs, but this is my first post and i dont think i can move it

Do you have a log file? If so, send me the snippet starting with "ClaustOrephobic scraping ore autoplaces." and ending with "Autoplace dump complete.".

My guess is that BZ is tampering with things and my parser can't find stuff. You should see "Could not find source..." or something to that effect in the log if that's the case.

where do i find logs?

Depends on your OS. On windows, it should be %appdata%/Factorio/factorio-current.log after loading the game.

https://wiki.factorio.com/Application_directory

The wiki has guides for other OSes. Should still be a text file called factorio-current.log. factorio-previous.log is the log from the previous time you loaded the game, and logs after that are purged.

Did some testing. This is indeed on BZLead’s end. They tamper with the richness expression of their resources and my mod doesn’t like that. I’ll make my error handling more robust and look into possibly being able to parse expressions that have been modified after being generated by core/lualib/resource-autoplace.lua, but no promises on a fix for these types of incompatibilities.

Alright. While looking through what BZLead is doing, it's actually possible for my mod to parse this. They're wrapping a recognizable expression in their own stuff, which I can actually detect and handle. I've got the actual noise expression stuff working right now in 1.1.1, but I'd like to support replacing the resource-autoplace.lua result in-place, rather than completely overwriting the expression, if possible.

Yep. As expected. BZ Lead's richness wasn't getting modified because they modified the richness function to downscale with distance in lead-ore.lua:

data.raw.resource["lead-ore"].autoplace.richness_expression =
richness * noise.if_else_chain(
noise.less_than(noise.distance_from(noise.var("x"), noise.var("y"), noise.var("starting_positions")), noise.to_noise_expression(200)), 1,
noise.less_than(noise.distance_from(noise.var("x"), noise.var("y"), noise.var("starting_positions")), noise.to_noise_expression(700)),
100 / (noise.distance_from(noise.var("x"), noise.var("y"), noise.var("starting_positions")) - 100),
0.17)

1.1.1 will support this kind of modification.

1.1.1 is released.
