This is my betting contract using eth/bnb, how can I change eth/bnb to token as their betting payment https://github.com/laronlineworld/BettingCOD/blob/main/BettingCOD.sol

Code for Betting

function bet(uint8 _teamSelected) public payable {
  require(bettingActive);
  //The first require is used to check if the player already exist
  require(!checkPlayerExists(msg.sender));
  //The second one is used to see if the value sended by the player is
  //Higher than the minimum value
  require(msg.value >= minimumBet);

  //We set the player informations : amount of the bet and selected team
  playerInfo[msg.sender].amountBet = msg.value;
  playerInfo[msg.sender].teamSelected = _teamSelected;

  //then we add the address of the player to the players array
  players.push(msg.sender);

  //at the end, we increment the stakes of the team selected with the player bet
  if ( _teamSelected == 1){
      totalBetsOne += msg.value;
  }
  else{
      totalBetsTwo += msg.value;
  }
}

Code for Distribution of prize

// Generates a number between 1 and 10 that will be the winner
function distributePrizes(uint16 teamWinner) public onlyOwner {
  require(bettingActive == false);
  address[1000] memory winners;
  //We have to create a temporary in memory array with fixed size
  //Let's choose 1000
  uint256 count = 0; // This is the count for the array of winners
  uint256 LoserBet = 0; //This will take the value of all losers bet
  uint256 WinnerBet = 0; //This will take the value of all winners bet

  //We loop through the player array to check who selected the winner team
  for(uint256 i = 0; i < players.length; i++){
     address playerAddress = players[i];

     //If the player selected the winner team
     //We add his address to the winners array
     if(playerInfo[playerAddress].teamSelected == teamWinner){
        winners[count] = playerAddress;
        count++;
     }
  }

  //We define which bet sum is the Loser one and which one is the winner
  if ( teamWinner == 1){
     LoserBet = totalBetsTwo;
     WinnerBet = totalBetsOne;
  }
  else{
      LoserBet = totalBetsOne;
      WinnerBet = totalBetsTwo;
  }


  //We loop through the array of winners, to give ethers to the winners
  for(uint256 j = 0; j < count; j++){
      // Check that the address in this fixed array is not empty
     if(winners[j] != address(0))
        address add = winners[j];
        uint256 bet = playerInfo[add].amountBet;
        //Transfer the money to the user
        winners[j].transfer(    (bet*(10000+(LoserBet*devFee /WinnerBet)))/10000 );
  }
  delete playerInfo[playerAddress]; // Delete all the players
  players.length = 0; // Delete all the players array
  LoserBet = 0; //reinitialize the bets
  WinnerBet = 0;
  totalBetsOne = 0;
  totalBetsTwo = 0;
}

How Can I change the eth/bnb to token as a betting payment and prize? Any guide? Thank you

you can inherit from ERC20 interface. then using token transferFrom() to replace Ether(msg.value) as Token for bet (deposit). use token transfer() for withdraw prize. don't forget, make sure your contract has an allowance amount from sender.

to be more secure, you can inherit SafeERC20 for compability with non-standard token.
