The PreventScreenLock method prevents the device screen from dimming and locking while your app is in the foreground.
Use this method for tilt based apps where the user is not touching the screen regularly to keep the device awake.
Also except false and true can have options app.PreventScreenLock( “Full” ), app.PreventScreenLock( “Partial” ).
app.PreventScreenLock( prevent );
function OnStart() { app.PreventScreenLock( true ); }
