how to change the data structure of playerInfo so that instead of one value for playerInfo[msg.sender].matchSelected, it would have a mapping of values. Also, you need to include resultSelected in the mapping so that the relation with matchSelected remains traceable. How can I apply the mapping of values and verify it on betting so that user can bet on different matches.
function bet(uint16 _matchSelected, uint16 _resultSelected) public payable {
require(matchBettingActive[_matchSelected], "Betting: match voting is disabled");
//Check if the player already exist
// require(!checkIfPlayerExists(msg.sender));
//Check if the value sended by the player is higher than the min value
require(msg.value >= minimumBet);
//Set the player informations : amount of the bet, match and result selected
playerInfo[msg.sender].amountBet = msg.value;
playerInfo[msg.sender].matchSelected = _matchSelected;
playerInfo[msg.sender].resultSelected = _resultSelected;
//Add the address of the player to the players array
players.push(msg.sender);
//Finally increment the stakes of the team selected with the player bet
if ( _resultSelected == 1){
totalBetHome[_matchSelected] += msg.value;
}
else if( _resultSelected == 2){
totalBetAway[_matchSelected] += msg.value;
}
else{
totalBetDraw[_matchSelected] += msg.value;
}
}
Everytime the user bets, the playerInfo reset the data. The concept is to bets on multiple matches using 1 address only.
also the distribution of prize:
function distributePrizes(uint16 matchFinished, uint16 teamWinner) public onlyOwner {
address[1000] memory winners;
//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
address add;
uint256 bets;
address playerAddress;
//Check who selected the winner team
for(uint256 i = 0; i < players.length; i++){
playerAddress = players[i];
//If the player selected the winner team, we add his address to the winners array
if(playerInfo[playerAddress].matchSelected == matchFinished &&
playerInfo[playerAddress].resultSelected == teamWinner){
winners[count] = playerAddress;
count++;
}
}
//We define which bet sum is the Loser one and which one is the winner
if ( teamWinner == 1){
loserBet = totalBetAway[matchFinished] + totalBetDraw[matchFinished];
winnerBet = totalBetHome[matchFinished];
}
else if ( teamWinner == 2){
loserBet = totalBetHome[matchFinished] + totalBetDraw[matchFinished];
winnerBet = totalBetAway[matchFinished];
}
else{
loserBet = totalBetHome[matchFinished] + totalBetAway[matchFinished];
winnerBet = totalBetDraw[matchFinished];
}
//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))
add = winners[j];
bets = playerInfo[add].amountBet;
uint256 amountToPlayer = (bets * (10000+(loserBet*devFee/winnerBet))) / 10000;
winners[j].transfer(amountToPlayer);
}
//Reset all variables
delete playerInfo[playerAddress];
players.length = 0;
loserBet = 0;
winnerBet = 0;
//10 will be the number of matches (To improve this)
for(uint256 k = 0; k < 10; k++){
totalBetHome[k] = 0;
totalBetAway[k] = 0;
totalBetDraw[k] = 0;
}
}
