Instantiate callback for clients?

Is there a callback to subscribe when an object is instantiated at runtime? So the other clients know that object has been created

Hi @jos_valentin. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Yes, when working with NormalVR's Normcore, you can be notified when objects are instantiated at runtime across clients using the RealtimeAvatarManager events. The RealtimeAvatarManager component provides two events that you can subscribe to: - avatarCreated: Triggered when a new avatar is created (including when other clients join) - avatarDestroyed: Triggered when an avatar is destroyed (including when clients leave) Here's how you can subscribe to these events:

using UnityEngine;
using Normal.Realtime;

public class MyAvatarManager : MonoBehaviour {
    private RealtimeAvatarManager _manager;

    private void Awake() {
        _manager = GetComponent<RealtimeAvatarManager>();
        _manager.avatarCreated += AvatarCreated;
        _manager.avatarDestroyed += AvatarDestroyed;
    }

    private void AvatarCreated(RealtimeAvatarManager avatarManager, RealtimeAvatar avatar, bool isLocalAvatar) {
        // Avatar created!
    }

    private void AvatarDestroyed(RealtimeAvatarManager avatarManager, RealtimeAvatar avatar, bool isLocalAvatar) {
        // Avatar destroyed!
    }
}

using UnityEngine;
using Normal.Realtime;

public class MyAvatarManager : MonoBehaviour {
    private RealtimeAvatarManager _manager;

    private void Awake() {
        _manager = GetComponent<RealtimeAvatarManager>();
        _manager.avatarCreated += AvatarCreated;
        _manager.avatarDestroyed += AvatarDestroyed;
    }

    private void AvatarCreated(RealtimeAvatarManager avatarManager, RealtimeAvatar avatar, bool isLocalAvatar) {
        // Avatar created!
    }

    private void AvatarDestroyed(RealtimeAvatarManager avatarManager, RealtimeAvatar avatar, bool isLocalAvatar) {
        // Avatar destroyed!
    }
}

This allows you to respond when avatars are created or destroyed in the room Avatars Documentation. For non-avatar objects instantiated with Realtime.Instantiate(), you can use Realtime's didConnectToRoom event to know when all realtime prefabs have been successfully connected to the datastore:

realtime.didConnectToRoom += DidConnectToRoom;

private void DidConnectToRoom(Realtime realtime) {
    // All realtime prefabs and views are now connected
}

realtime.didConnectToRoom += DidConnectToRoom;

private void DidConnectToRoom(Realtime realtime) {
    // All realtime prefabs and views are now connected
}

This event fires when Realtime is connected to a room and all realtime prefabs and views in the scene have been successfully connected Realtime Reference. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

just make the object self register with a controller on Awake / Start
