I am developing a game on the blockchain platform, this game is a dose game. The scenario of the game is that a user creates a game and a contract is created, other users can see the list of games or the same contracts and join the game and play. I want when the user created the game and no one joined his game, he can cancel the game and get back the amount of coins he deposited. I wrote a method called cancel, but this method does not work properly and calculates the amount of gasfee too much.

This is the error I get:

  • Is addressWage a contract? Cause if it is, it needs a fallback or receive function.

If addressWage is a contract, it needs to have a receive or a fallback function in order to be able to receive ether balance. Simply:

receive() external payable {…}

Moreover, the transfer call needs to specify addressWage as payable:

payable(addressWage).transfer(wage)
