'How to create an infinite lotto system in solidity
I'm trying to create a Lotto where the owner can generate as many Lottos as they want. To do this I have used a struct and a mapping to hold all the Lotto. But I want to make a function where people can enter the Lotto of their choice (with the id).
Here is my code for the moment (there is no code for the 'enter' function because I can't do it) :
struct Lottos {
uint maxPlayers;
string winObject;
address depositAddress;
string name;
uint id;
bool ended;
}
mapping(uint => Lottos) lottos;
address payable[] public players;
mapping(address => uint balance);
uint public price;
function createLotto(uint _id, string _name, address _depositAddress, string _winObject, uint _maxPlayers, bool _ended) public onlyOwner {
Lottos memory newLotto = Lottos(_maxPlayers, _winObject, _depositAddress, _name, _id, _ended);
lottos.push(newLotto);
}
function totalLottos() public view returns (uint) {
return lottos.length;
}
function checkLotto(uint i) public view returns (uint, string, address, string, uint, bool {
return (lottos[i].maxPlayers, lottos[i].winObject, lottos[i].depositAddress, lottos[i].name, lottos[i].id, lottos[i].ended);
}
