@JohnFromGWN said in [Tutorial] Help Notification (Key or blips etc.) C# SHVDN3:
probably more efficient to work with natives
Same amount of efficiency in terms of "run time". Less efficient in terms of "dev time".
SHVDN's functions use Function.Call as well. Screen.ShowHelpText is nearly identical to Kangouroux6's function. The only differences are that the inputType parameter is "CELL_EMAIL_BCON" instead of "STRING" (I'm not aware of the effect this has), and it allows longer strings to be used. Efficiency is essentially identical.
So as JustDancePC said, you can certainly go the manual native calling route, but it really is just a waste of time figuring out how to use the natives when SHVDN has already figured it out for you. Plus it's just extra bloat in your code. If you want to know if a native is already implemented in SHVDN, just search for the native in its GitHub repo.
