Calls a “write” method on the given contract. OnTransactionSent is executed when the transaction is sent by the connected wallet sucessfully; you must wait for OnTransactionConfirmed to return to use ConfirmedTransaction or FinalStatusCode (all error handling should be done after OnTransactionConfirmed).

Inputs

Type	Name	Description
UObject*	WorldContextObject	The WorldContextObject for this function. This is mainly used for registering the async method with the GameInstance.
UEmergenceDeployment*	DeployedContract	The deployed contract.
FEmergenceContractMethod	MethodName	The method to call.
FString	Value	The amount to transfer from sender to recipient (in Wei, or equivelent).
TArray	Parameters	The parameters to call the method with.
FString	PrivateKey	(Optional) The private key of the account to call the method with. Leave blank to call with the WalletConnect’d wallet / Futureverse custodial wallet.
FString	GasPrice	(Optional) The gas price to use if we’re calling with a private key.
int	NumberOfConfirmations	The number of confirmations to wait for before deciding this transaction “confirmed”.
float	TimeBetweenChecks	The amount of time between checks in seconds.

Outputs

Type	Name	Description
FEmergenceTransaction	ConfirmedTransaction	The final transaction status data.
EErrorCode	FinalStatusCode	Any errors that occured trying to get the data.

C++

Module: EmergenceBlockchainWallet include: #include "WalletService/WriteMethod.h"

static UWriteMethod* WriteMethod(UObject* WorldContextObject, UEmergenceDeployment* DeployedContract, FEmergenceContractMethod MethodName, FString Value, TArray<FString> Parameters, FString PrivateKey, FString GasPrice, int NumberOfConfirmations = 5, float TimeBetweenChecks = 5.0F) - instantiates this async method. Activate() - Activates this async method. In C++, the outputs of the async function can be acted upon by binding to the event delegate “FOnTransactionConfirmed”. You can also bind to FOnTransactionSent, for when the transaction was sent but not yet confirmed.

Additional Information

This class or its parent class inherits from UEmergenceCancelableAsyncBase, and thefore also has the following functions that can be called on it:

void Cancel() - Cancels the requests.

bool IsActive() - Checks if the requests are in-flight.
