Message configs are now selected based on the client's language (can be
toggled in the config) and will use MineDown formatting to allow
display of component messages as well as usage of RGB colors in 1.16.
If found the legacy local.yml will be used instead of the per-language
files. Move your local.yml to the correct lang config to if you want to
use the per-client language option.
Version was also changed to 3.11 due to the many internal changes that
have accumulated over time
This resolves issues when multiple listeners try to handle the same
events e.g. for group support which would've passed it onto the normal
listeners leading to errors
Also add tax bypass permissions (#204, ChestShop.notax.buy/sell). When buying with that permission the buyer does not have to pay the tax (the seller will still get the reduced amount), when selling the seller will get the full amount instead of one lowered by the tax.
The permissions of the shop owner play no role due to there not being a good way of checking offline player permissions and it being a bit non-obvious for the buying/selling player if a shop would be with or without tax. This way all that gets changed is the amount the player pays/receives and not the shop owner (and the player should know their permissions/rank already)
The transfer event was necessary in order to correctly resolve who triggered the transaction. Economy adapters are now required to implement a listener for each of the events. It's also recommended that economy adapters that support transfers directly use that instead of passing it through subtract and add with the processTransfer method.
This changes events to store the database Account instead of an OfflinePlayer and deprecates any event method that uses/returns OfflinePlayer. This is necessary as Bukkit#getOfflinePlayer(String) queries Mojang for the UUID when the user was not found in the local cache. As we already store this information (name to UUID mapping) in our database we should not have no need to rely on querying Mojang. (This might make transactions fail for shop owners that haven't played before but that shouldn't really be an issue in most cases)
This also fixes some conditions under which the STACK_TO_64 option did not get applied correctly and wrong inventory space checking for items with a max stack size of less than 64
Inspired by @Brokkonaut's fork this adds a new NOT_ENOUGH_SPACE_IN_YOUR_SHOP message to send to the shop owner when someone tries to sell to his shop. It also adds new %world, %x, %y and %z variables to display the shop's location in the message, adds a config option to make both the full-shop and out-of-stock messages respect /cstoggle and makes values in the locale.yml support ampersand color codes.
