Calling SCORE Methods

This section provides an explanation about ways of executing various method types in different Jupyter Notebook cells.

Readonly Method

First we need to check the status of our game whether it's on or off.
For that we have get_game_status method in our SCORE.
Execute this cell using Ctrl + Enter in Jupyter Notebook.
_call = CallBuilder()\
.from_(deployer_wallet.get_address())\
.to(<YOUR_SCORE_ADDRESS>)\
.method("get_game_status")\
.build()
response = icon_service.call(_call)
print(response)
CallBuilder() doesn't send any transaction to the blockchain.
If the response is True, the game is on else it is turned off.

External Method

If the game is off you need to change the game status to on before being able to play the game.
For that we have toggle_game_status method in our SCORE.
Execute this cell using Ctrl + Enter in Jupyter Notebook.
Your game will be turned off if it is already in "on" status.
call_transaction = CallTransactionBuilder()\
.from_(deployer_wallet.get_address())\
.to(<YOUR_SCORE_ADDRESS>)\
.nid(NID)\
.nonce(100)\
.method("toggle_game_status")\
.build()
estimate_step = icon_service.estimate_step(call_transaction)
step_limit = estimate_step + 100000
# Returns the signed transaction object having a signature
signed_transaction = SignedTransaction(call_transaction, deployer_wallet,step_limit)
# Reads params to transfer to nodes
print(signed_transaction.signed_transaction_dict)
# Sends the transaction
tx_hash = icon_service.send_transaction(signed_transaction)
@retry(JSONRPCException, tries=10, delay=1, back_off=2)
def get_tx_result(_tx_hash):
tx_result = icon_service.get_transaction_result(_tx_hash)
return tx_result
get_tx_result(tx_hash)
If the status is "1", your transaction succeeded. You can copy the tx_hash and see your transaction in the tracker.
Now you can also execute above readonly cell to see change in result.

Payable Method

Before being able to play the game ,one more thing you need to do is to fill some ICX in Dice SCORE for treasury. For that goto section ICX Transfer
Now lets place our first bet using method call_bet in our Dice SCORE.
Execute this cell using Ctrl + Enter in Jupyter Notebook.
params={
"upper": 50,
"lower": 5,
"user_seed": "Lucky",
"side_bet_amount": 10**18,
"side_bet_type":"icon_logo1"
}
# Skip side_bet_amount and side_bet_type if you dont want to play sidebet
call_transaction = CallTransactionBuilder()\
.from_(caller_wallet.get_address())\
.to(<YOUR_SCORE_ADDRESS>)\
.nid(NID)\
.nonce(100)\
.value(10**18)\
.method("call_bet")\
.params(params)\
.build()
estimate_step = icon_service.estimate_step(call_transaction)
step_limit = estimate_step + 100000
# Returns the signed transaction object having a signature
signed_transaction = SignedTransaction(call_transaction, caller_wallet,step_limit)
# Reads params to transfer to nodes
print(signed_transaction.signed_transaction_dict)
# Sends the transaction
tx_hash = icon_service.send_transaction(signed_transaction)
@retry(JSONRPCException, tries=10, delay=1, back_off=2)
def get_tx_result(_tx_hash):
tx_result = icon_service.get_transaction_result(_tx_hash)
return tx_result
get_tx_result(tx_hash)
You can get the information about your win, loss and payout amount from the eventlogs.
