How to test blokchain lottery using Chainlink VRFv2 and Chainlink Keeper?

Asked 2022-Mar-14 at 17:39

Thanks to Patrick and after reading the Chainlink's blog on how to build blockchain lottery, I am eager to build a similar "version". It will be using the latest Chainlink's version of VRFv2 and Keeper.

However, the supported test networks for VRFv2 and Keeper are Rinkeby and Kovan, respectively.

So any hint on how to approach this?

ANSWER

Answered 2022-Mar-14 at 17:39

For now the one of the only testnet's both Keepers and VRF v2 are available on is the BNB testnet. You can test your application there until VRF v2 and keepers are available on the same Ethereum testnet.

ANSWER

Answered 2021-Oct-18 at 20:44

Here is a simpler approach which avoids all the warnings (and errors on other simulators). Randomly generate the set of 6 winners. Also, randomly pick one of the winners to be replaced with a losing number. Using post_randomize, create the set of losers, then randomly pick one of them and replace one of the winners.

Remove input value on backspace keyup

Asked 2022-Feb-08 at 14:19

I have a small canonical lottery search form comprising of 6 input fields. Currently when the user backspaces once, it will remove the value and move to the previous input field.

I need to split the above process into two steps. Therefore one backspace removes the value, the second backspace moves to previous input field and repeat.

How can I achieve this by adding to my current jquery if/else statement?

QUESTION

How can I prevent my function from treating "0" as empty?

Asked 2022-Feb-08 at 09:19

I have a lottery search form which concatenate six input fields into a single value and returns the ticket results based on the position. My form works correctly for numbers 1-9, but it is unable to display results when I search for 0.

I believe this is because within my get_numbers() function, the value of '0' is being treated as empty: https://www.php.net/manual/en/function.empty.php

How can I fix my if else statement to stop it treating 0 as empty?

...

ANSWER

Answered 2022-Feb-08 at 06:29

You're correct that empty() returns TRUE for 0.

You could instead use filter_input() with the FILTER_VALIDATE_INT filter applied.

You could even simplify the whole thing with a range map...
