Inherits: Initializable, IERC777Recipient

Logic to handle rewards that user can send to character and note.

State Variables

ERC1820_REGISTRY

IERC1820Registry public constant ERC1820_REGISTRY =
    IERC1820Registry(0x1820a4B7618BdE71Dce8cdc73aAB6C95905faD24);

TOKENS_RECIPIENT_INTERFACE_HASH

bytes32 public constant TOKENS_RECIPIENT_INTERFACE_HASH = keccak256("ERC777TokensRecipient");

_web3Entry

address internal _web3Entry;

_token

address internal _token;

Functions

initialize

Initialize the contract, setting web3Entry address and token address.

function initialize(address web3Entry_, address token_) external initializer;

Parameters

tokensReceived

Called by an {IERC777} token contract whenever tokens are being moved or created into a registered account to (this contract).
The userData/operatorData should be an abi encoded bytes of fromCharacterId, toCharacter and toNoteId(optional), which are all uint256 type, so the length of data is 64 or 96.

function tokensReceived(
    address,
    address from,
    address to,
    uint256 amount,
    bytes calldata userData,
    bytes calldata operatorData
) external override(IERC777Recipient);

getWeb3Entry

Returns the address of web3Entry contract.

function getWeb3Entry() external view returns (address);

Returns

getToken

Returns the address of mira token contract.

function getToken() external view returns (address);

Returns

_tipCharacter

Tips a character by transferring amount tokens from the fromCharacterId account to toCharacterId account.
Emits the TipCharacter event.
User should call send erc777 token to the Tips contract, with fromCharacterId and toCharacterId encoded in the data.
send interface is IERC777-send, and parameters encode refers AbiCoder-encode.
Requirements:

• The from account must be the character owner of `fromCharacterId.

function _tipCharacter(
    address from,
    uint256 fromCharacterId,
    uint256 toCharacterId,
    address token,
    uint256 amount
) internal;

Parameters

_tipCharacterForNote

Tips a character's note by transferring amount tokens from the fromCharacterId account to toCharacterId account.
Emits the TipCharacterForNote event.
User should call send erc777 token to the Tips contract, with fromCharacterId, toCharacterId and toNoteId encoded in the data.
Requirements:

• The from account must be the character owner of `fromCharacterId.

function _tipCharacterForNote(
    address from,
    uint256 fromCharacterId,
    uint256 toCharacterId,
    uint256 toNoteId,
    address token,
    uint256 amount
) internal;

Parameters

_sendToken

function _sendToken(
    address from,
    uint256 fromCharacterId,
    uint256 toCharacterId,
    address token,
    uint256 amount
) internal;

Events

TipCharacter

Emitted when the assets are rewarded to a character.

event TipCharacter(
    uint256 indexed fromCharacterId, uint256 indexed toCharacterId, address token, uint256 amount
);

Parameters

TipCharacterForNote

Emitted when the assets are rewarded to a note.

event TipCharacterForNote(
    uint256 indexed fromCharacterId,
    uint256 indexed toCharacterId,
    uint256 indexed toNoteId,
    address token,
    uint256 amount
);

Parameters

Errors

ErrCallerNotCharacterOwner

error ErrCallerNotCharacterOwner();
