Getting correct objects positions when joining a running game

develax

If I'm not mistaken, when joining a running game it seems that the objects first appear at their initial positions on a new joined player's map and only a moment after they are moved to their current gameplay positions via PhotonView sync mechanism. It is usually hardly visible to the eye but sometimes it produces some artefacts such as the intersection of objects. How to make objects appear in the right places before the very first synchronization is performed?

Any ideas on how to manage this issue? Maybe there is some event that tells that all objects' been synchronized, and then a new player's character can be instantiated?

I noticed that only objects created by PhotonNetwork.Instantiate are buffered and then sent to a new client whenever it joins.

public float smoothPosition = 5f;
public float smoothRotation = 10f;
public PhotonView pv;
bool setPos = false;
Vector3 correctPlayerPos = Vector3.zero;
Quaternion correctPlayerRot = Quaternion.identity;

    public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
    {
        if (stream.IsWriting)
        {
            stream.SendNext(transform.position);
            stream.SendNext(transform.rotation);
        }
        else
        {
            correctPlayerPos = (Vector3) stream.ReceiveNext();
            correctPlayerRot = (Quaternion) stream.ReceiveNext();

	   if(!setPos) SetSpawnPosition(correctPlayerPos);
        }
    }

    void Update()
    {
        if(!pv.IsMine && setPos){
	transform.position = Vector3.Lerp(transform.position, correctPlayerPos, Time.deltaTime * smoothPosition);
	transform.rotation = Quaternion.Lerp(transform.rotation, correctPlayerRot, Time.deltaTime * smoothRotation);
	}	
    }
	
	void SetSpawnPosition(Vector3 correctPos)
	{
		if(Vector3.Distance(transform.position, correctPos) > 1.0f ){
			transform.position = correctPos;
		}
		setPos = true;
	}

@OneManArmy don't you make the object invisible until you call SetSpawnPosition? Without it, the instantiated object has time to flash on the screen for a moment.

It's up to you. You can even move map above 0 on Y axis.
