Visual scripting scripts are prepared in a way in which you make fewer errors, not allowing you to write incorrect syntax like C# script does. If you are an experienced programmer, I bet you are quite familiar with them, but let’s recap the common errors that will make you lose lots of time when you start out with C# scripting.
