I have a confusion about when and where to use NetworkServer.RegisterHandler() and NetworkManager.singleton.client.RegisterHandler()? And also I am getting Unknown message ID 1002 error.
I have a message class
public class NetworkMsgHandler : NetworkBehaviour {
public const short movement_msg = 1002;
public class BulletMovementMsg : MessageBase {
public string objectName;
public Vector3 objectPosition;
public Quaternion objectRotation;
public float time;
}
}
I have ServerRelay which has ServerOnly authority has Script ServerRelay for registering Message Handler on Server.
public class NetworkServerRelay : NetworkMsgHandler {
private void Start()
{
if(isServer)
{
RegisterNetworkMessages();
}
}
private void RegisterNetworkMessages()
{
NetworkServer.RegisterHandler(movement_msg, OnReceivePlayerMovementMessage);
}
private void OnReceivePlayerMovementMessage(NetworkMessage _message)
{
BulletMovementMsg _msg = _message.ReadMessage<BulletMovementMsg>();
NetworkServer.SendToAll(movement_msg, _msg);
}
}
Then I have Bullet GameObject it has script Projectile which is sending movement message this class is derived from NetworkMsgHandler.
public class NetworkProjectile : NetworkMsgHandler {
private void Start() {
if (localPlayerAuthority) {
canSendNetworkMovement = false;
RegisterNetworkMsg();
}
else {
isLerpingPosition = false;
isLerpingRotation = false;
realPosition = transform.position;
realRotation = transform.rotation;
}
}
private void RegisterNetworkMsg() {
NetworkManager.singleton.client.RegisterHandler(movement_msg, OnReceiveMovementMsg);
}
private void OnReceiveMovementMsg(NetworkMessage networkMessage) {
Debug.Log("Message received");
BulletMovementMsg msg = networkMessage.ReadMessage<BulletMovementMsg>();
if(msg.objectName != transform.name) {
ProjectileManager.Instance.SpawnedBullets[msg.objectName].GetComponent<NetworkProjectile>().ReceiveMovementMsg(msg.objectPosition, msg.objectRotation, msg.time);
}
}
public void ReceiveMovementMsg(Vector3 position, Quaternion rotation, float _timeToLerp) {
//lerping between position
}
private void Update() {
if(!canSendNetworkMovement) {
canSendNetworkMovement = true;
StartCoroutine(StartNetworkSendCoolDown());
}
}
private IEnumerator StartNetworkSendCoolDown() {
timeBetweenMovementStart = Time.time;
yield return new WaitForSeconds((1 / networkSendRate));
SendNetworkMovement();
}
public void SendNetworkMovement() {
timeBetweenMovementEnd = Time.time;
SendMovementMsg(bulletID, transform.position,transform.rotation, (timeBetweenMovementEnd - timeBetweenMovementStart));
canSendNetworkMovement = false;
}
public void SendMovementMsg(string _bulletID, Vector3 position, Quaternion rotation, float timeToLerp) {
BulletMovementMsg _msg = new BulletMovementMsg() {
objectRotation = rotation,
objectPosition = position,
objectName = bulletID,
time = timeToLerp
};
NetworkManager.singleton.client.Send(movement_msg, _msg);
}
}
So whenever a bullet spawns it generates an error on client side saying Unknown message ID 1002 connId:1 UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()
