Show scene once after lunching the game

Question

Hello! I'm making a game and I want to add a tutorial(walkthrough) at the beginning of the game. So, I created a scene where I have all the information and now I just want to show it once after the game was launched and never show it again.

I have already search on the internet for the information. I only found some info about PlayerPrefs and I don't really know how to use it.

Thank you for your time!

You can set variable in PlayerPrefs like this:

PlayerPrefs.SetInt("IsFirstRun", 1);

and then you can check if the variable exists:

if(PleyerPrefs.HasKey("IsFirstRun")) // show the scene

This is how your script would look:

void Start()
{
     if(!PleyerPrefs.HasKey("IsFirstRun"))
     {
     // open scene
     PlayerPrefs.SetInt("IsFirstRun", 1);
     }
}
