Thought it would be a pretty cool idea. I may be down to write this myself if you'd like.
Basically after a certain interval something would be broadcasted like "CF started!", which be automatically done by console or something, with a random amount.

When a player puts up a coinflip and leaves the coinflip does not get removed and if another player accepts the coinflip and wins they will only get their own money; if the offline players wins neither will get their money

PS: How does one go about building this plugin?
Not your standard setup it seems, no pom.xml and all.

Hello,

Can you update the compatibility with CombatLogX to the latest update? Because it is no longer compatible with the last dev-build of CombatlogX.

Thanks you :)

Best regards,

Running CoinFlipper 2.42 and paperspigot 1.8.8, starting a game spammed the console with this error:

The game never starts/completes so the two players involved can't compete in any other games, as they are technically still in a game.

1.15 support please

If game is in progress and server shuts down both users lose money.
Instead, the shutdown process of CoinFlipper should allow all current games to finish before disabling plugin.

LOG:
https://pastebin.com/mVLabKr9fbclid=IwAR2aPPCFQPQH2d1u5Xs5KKgHRoESNtMMiTCFvN0TsRqSwcRosEZVnKoUl2k

Version:
CoinFlipper: 2.4_3
CombatLogX: 9.9.2.1

New update (4.0.0+) changed the API code
The new code is now Combat.isInCombat(player);

When a user creates a bet he does not win, that the amount of money is returned formatted; Example 4k, 4M 4B, etc
Sorry, my english is so bad.
A lot of thanks!

This is the error via the console.
