Creating a vibration in a non-activity class?

Question

I am trying create a vibration for my game(Android), basically I want a vibration to start when a collision happens, but I can't create it because the class in which my level is running is not an activity class and I don't know ho to proceed, what should I do ? Thanks.

Answer 1

Use this one:

public void startVibrate(Context context, int repeat) {
    vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
    int dot = 200;          // Length of a Morse Code "dot" in milliseconds
    int dash = 500;         // Length of a Morse Code "dash" in milliseconds
    int short_gap = 200;    // Length of Gap Between dots/dashes
    int medium_gap = 500;   // Length of Gap Between Letters
    int long_gap = 1000;    // Length of Gap Between Words
    long[] pattern = {
            0,  // Start immediately
            dot, short_gap, dot, short_gap, dot, medium_gap,    // S
            dash, short_gap, dash, short_gap, dash, medium_gap, // O
            dot, short_gap, dot, short_gap, dot, long_gap       // S
    };
    vibrator.vibrate(pattern, repeat);
    //vibrator.vibrate(10000);
}

But your class that wants to create it should be called from an activity right? Then there is no problem to proceed like a vibration done in Activity Class:

public function vibrate(Context context){
    // Get instance of Vibrator from current Context
    Vibrator v = (Vibrator) getSystemService(context);

    // Vibrate for 300 milliseconds
    v.vibrate(300);
}
