Ep.7 - Write to contract from game - Web3.UE Blockchain Tutorial in Unreal Engine 5
In today's episode, we write data into a smart contract directly from the game.
While doing the actual test the gas price spiked from 30 to over 80, resulting in slow transaction verification, that kind of confused me ;) But thanks to that I was able to show some debugging processes to go thru when unexpected things happen.
