Algorithm to determine the extend of ore patches about factorio-stdlib HOT 12 CLOSED

Resource (patch) detection and getting the bounding box are now in with #93.

from factorio-stdlib.

Definitely sounds like a useful feature. Go for it.

I agree on it being usefull

Some things to think about.
What defines an ore patch, if there is a gap of XXX tiles is it still part of the same patch?
What if the patch is a combined patch with say coal/iron etc etc.

Probably the best fit for it would be stdlib/entity/resource.lua

I am currently (very slowly) writing a data stage Prototype module. As well as a player/force/surface event module

My definition of an ore patch: Connected in the 4 main directions + 4 diagonals, no gaps and one single ressource.
Can't remember a case where i'd see 2 copper patches close enough together to consider them 1 patch.

Probably worth checking out https://github.com/narc0tiq/YARM When i used it back in the days it always marked what i would have expected.

YARM has a compatible license so if any code is reused there, we just need to attribute it in the file.

Need any help @Pandemoneus? I've contributed a bit to YARM myself and it sounds like the others are interested too.

Alright, haven't had time working on it yet, but I will start now. I've asked Rseding whether he could expose what they use for the Factorio minimap on ore patches, but he redirected me to one of his older mods, namely Landfill: https://mods.factorio.com/mods/Rseding91/Landfill

I'll see that I can get a first version up, I am sure there will be possible performance improvements.

Alright, got the first version for resource scanning up: https://github.com/Pandemoneus/Factorio-Stdlib/blob/master/stdlib/resources/resources.lua

from factorio-stdlib.

return resource_at_tile[1] -- there should never be another resource at the exact same coordinates
There can be more than one resource on a tile,

Also, if you do it as a pull request it becomes a lot easier to make review comments :)

Alright. Under which circumstances can there be more than one resource on a tile? I took that code from YARM.

from factorio-stdlib.

Its rare but it does happen in vanilla, additionally mods can "stack" them
