Custom Livestock Vendor

To add a custom livestock vendor, add entry to Data/FarmAnimals normally, then:

Add Data/FarmAnimals CustomFields entry "mushymato.LivestockBazaar/BuyFrom.{{ModId}}_MyVendor": true to the farm animal. {{ModId}}_MyVendor is value that will be referred to as shopName in following parts of this guide. Prefix this with your mod id when your vendor is a vanilla NPC.
(Optional) Add CustomFields entry "mushymato.LivestockBazaar/BuyFrom.Marnie": false to prevent Marnie from selling this animal. Marnie is the special hardcoded shopName this mod uses to refer to the vanilla animal shop. Unlike all other BuyFrom fields, BuyFrom.Marnie defaults to true and need to be explicitly set to false.
Use map tile action mushymato.LivestockBazaar_Shop to create a shop.

Usage: mushymato.LivestockBazaar_Shop \<shopName\> [direction] [openTime] [closeTime] [ownerRect: [X] [Y] [Width] [Height]]

The arguments of this tile action is identical to "OpenShop" from vanilla.

Property	Type	Default	Notes
