Some attachments can have a larger radius than others
Some tools, particularly watering and scythe, get used a lot in farms that are built around using the tractor. It's really nice to have those tools have a bigger impact area than tools like the hoe, where you'd rather have more precision.
This adds a new setting "ExtendedDistance" to the Scythe, Waterer, Seeder and Fertilizer tools. It's just a boolean setting which allows for one more than the default radius. It's a simple boolean setting to make it simpler for the user. Any area of affect greater than the default 3x3/5x5 throws out all notions of game balance anyway, so the main 'Distance' setting will be good enough for people who want to go bigger.
We discussed this on Discord, but I'll just summarize here for the record.
I'm planning to change the approach so that, instead of each attachment having an IsDistanceExtended bool option to use a second distance value, players will be able to override the distance per-attachment. In Generic Mod Config Menu, it'd appear as a distance slider where the default value is "use default distance".
I'm mostly working on compatibility updates until the dust settles on the Stardew Valley 1.6 update, so I'll mark this as a draft until we can make those changes.
I'd want to reimplement this per my earlier comment, but it's been in draft for over a year and I haven't seen players asking for a feature like this. So unfortunately I don't have any current plans to work on it. Thanks for the PR though, I do appreciate the contribution even if it ended up not being merged!
