c# - Multiple messages from Xamarin Messaging center when application is restarted -


i have xamarin forms application in use messagingcenter send data specific platform xamarin.forms application.

in page subscribe messages in base.onappearing() , unsubscribe in base.ondisappearing() method. works expected.

the problem i'm having when application get's stopped androidos (example of when change language of device) start getting copies of messages. i'm confused why happening noticed base.ondisappearing() method not called when application restarted.

does have idea cause problem , how fix it? also, there way in xamarin see publishers , subscribers?

like greensy said, in addition subscribing in onappearing() , unsubscribing in ondisappearing(), unsubscribe message before subscribing because, why not:

protected override async void onappearing() {     base.onappearing();      messagingcenter.unsubscribe<string>(this, "keyhere");     messagingcenter.subscribe<string>(this, "keyhere", string => { })); }

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
