    public void SP(bool change)
    {
        play = change;
        return;
    }

    public void RP()
    {
        play = false;
        index = 0;
        wait = 0.0f;
    }
}

this is my code and i’ve been making an app that would read music sheet notes and simulate pressing them
,i know that it’s a game engine but i wanted to try this on unity.
any way i’m using a pre-made namespace that i downloaded to simulate key press ,
but i don’t think it is the problem because it doesn’t get there.
the moment i hit play Unity crashes.
any help ?

PPiano is stuck in an infinite loop. Add “yield return null;” just before the closing “}” of the “while (true){” loop to let other things on the Unity thread get processed and move to the next update cycle.
