Now introducing: History - check your or other player's game history. Just use /coinflipper history (player) and you can check it out. Old games before the update are also showed - but without the money values as those weren't stored before.
The way stats are saved have been changed. They are now automatically fetched from the games recorded. They will be automatically converted on first launch. This may take some time. If you wish skip converting, feel free to delete the stats.db file (if sqlite) or delete coinflipper_stats table(if mysql). Note this will delete the stats.
Added new cvar, animation_only_challenger: false, which when sat to true makes animations only play for the player who challenged bet, not the player who placed it.
You can now edit messages.yml in /coinflipper config.
Code is hugely optimized. config.yml, messages.yml and materials.yml edition is finally not buggy.
Fixed a few critical bugs.Fortunately this also means that the plugin probably works for 1.13. It isn't tested though, so use at your own risk.
Unfortunately, you can no longer edit the messages.yml file through /coinflipper config. This is due to the feature being too unstable and creating issues. Sign Input API is also not available on newer versions than 1.12 as it may have crashed some players.
Plugin will now automatically use SQLite instead of .yml for saving. YOU NEED TO RUN '/COINFLIPPER CONVERT' ON SERVER START TO MOVE OLD STATS TO THE NEW SYSTEM.
Ability to change materials in the selectionscreen and creation GUI. More interfaces will come in the next updates. Changing available in materials.yml file.
Added new messages when player tries to set a custom value of bet less than minimal amount or more than maximal.
You might now specify how you want to format the numbers in the config. Use the value 'formatting_shorten_money' in the config.yml. When set to true, numbers will be shortened (1000000->1M), and while false they will be formatted with commas(1000000->1,000,000)
Replaced tier 6 money emerald in Bet Creation GUI, instead you can now automatically set the bet to your max money(or to max bet value if the players balance is above that).
Blocks players from challenging players who are already inside a CoinFlipper game. Message can be modified changing the 'BET_CHALLENGE_ALREADYSPINNING' field in messages.yml.
