__VRFConsumerBaseV2_init(address) :
This function is an internal function used to initialize the VRFConsumerBaseV2 contract. It sets the address of the VRFCoordinator contract, which is used to interact with the VRF system. It also sets the state of the contract to "onlyInitializing" to ensure that no other functions can be called until the initialization is complete. (autogenerated documentation)
__VRFConsumerBaseV2_init_unchained(address) :
This function is used to initialize the VRFConsumerBaseV2 contract. It sets the address of the VRFCoordinator contract, which is used to coordinate the VRF process. This allows the VRFConsumerBaseV2 contract to interact with the VRFCoordinator contract and access its functions. (autogenerated documentation)
fulfillRandomWords(uint256,uint256[]) :
This function allows the VRF Coordinator to fulfill a request for random words. It takes two parameters: a request ID and an array of random words. The function checks that the sender is the VRF Coordinator, and if so, calls the fulfillRandomWords() function to fulfill the request. (autogenerated documentation)
rawFulfillRandomWords(uint256,uint256[]) :
This function allows the VrfCoordinator to fulfill a request for random words. It takes a request ID and an array of random words as parameters. The function then calls the fulfillRandomWords() function, which stores the random words in the mapping associated with the request ID. (autogenerated documentation)
