2 years later and the tutorial worked flawlessly. Just a few differences in the Solidity UI. This is exactly what I needed to get started immediately. No Git, no Node, no npm, just code and debugging. Thanks a million. Thumbs up & suscribed.

uint refers to uninsigned int which are non negative numbers. Use different variable types for correct results.

@cryptophoenix2023
@cryptophoenix2023 3 года назад
Depending on which version of Solidity you are using, it'll either revert or it'll result in an underflow. I think 0.8.0+ will result in a revert error, and anything below that will result in an underflow. If you don't know what underflow/overflow is then look it up, it's kinda cool but also extremely bad for smart contracts if it happens lol

Each time the function is called, a transaction happens, right? Why doesn't it need to wait for confirmation? It seems to increment/decrement instantaneously. Is that just because of the simulated environment?
