I can provide you with an article based on the specification specified. Please note that I will assume that Createsubsubscription (), Gertubid () are already implemented and available in the JavaScript code.
Ethereum: Creating and setting up Unterdel with VRF coordinators
In this article we will examine how dungeons are created and determined in a fixed environment using VRF coordinators (verification of random features).
Show hardhat environment
Hardhat is a popular Ethereum development framework with which we can create and implement intelligent contracts in the Ethereum network. It offers a simple interface for interaction with Ethereum blockchain, which makes it ideal for fast prototypes and development.
Create and set up Unterdel with VRF coordinators
To create dungeons with VRF coordinators in Hardhat, you have to:
- Imports required dependencies
- Set up our network configuration
- Create a copyvrfcoordinator
- Call up the functionCreatesubsuBtung () and pass it on as an argument for the” setsubid
method "
- Take the subordinates with the "Getubid method”
Hardhat implementation script (deceplage.js)
`JavaScript
Const {network, Eters} = requirement (“@nomiclab/hardhat”);
// define our network configuration
Const Networks = {
Hardhat: {
Chainid: 1337,
// Add other network configurations as required
},
};
// import the VRF coordinator library
Const vrfcoordinatorv2_5mock = required (“./ vrfcoordinatorv2_5mock”);
Asynchrical function main () {
Const {Getchainid} = Wait for Eulers.GetContractface (“Your contract name”);
Const Contentstance = Waiting Getchainid ();
// Create a subscription copy with a VRF coordinator
Const subscription substance = wait for vrfcoordinatorv2_5mock.createsubscription ({{{{{{{{{{{{{{{{{{{{
Chainid: contracttance.chainid,
Supplier: Network.Provider,
});
// Set subid with the function of the createsubscription ()
Expect a subscription substance.
Console.log (expect vrfcoordinatorv2_5mock.getsubid ());
// Get the subdia with the Gertubid method
Const subid = wait for vrfcoordinatorv2_5mock.getsubid ();
console.log (subid);
}
primarily ();
`
In this script, we first import the necessary dependencies and create our network configuration. Then we create a “VRFCoordinator” samples with VRF coordinator version 2.5 -Mock.
Then we create a copy of a subscription with the “Createsubsubscription ()” function and convey them as an argument for the set -subid method. This determines the submission for the specified contract.
Then we register the subid with the “Gestubid”
Note:
replace `your contract name” with the actual name of your Ethereum contract and replace “” Your Sub-ID “with the desired value of the sub-line. This script suggests that you have VRF coordinator version 2.5.
