-Using `Invoke`, `InvokeRepeating`, `CancelInvoke`, `StartCoroutine` or `StopCoroutine` with a first argument being a string literal is not type safe. Instead it's recommanded to use the `nameof` operator or a direct call for coroutines. The further benefit of doing this is the ability for the method to use a rename refactoring without remembering to update the string literals.
