CSP / Predicted Spawn / NetworkCollider2D

[upbeat locust]

Basically, these functions are called from my Player's [Replicate] method :

        public override void LogicUpdate(PlayerRunInputs md, ReplicateState state)
        {
            base.LogicUpdate(md);
            if (state == ReplicateState.CurrentCreated)
                FireProjectile(md.AimDirectionInput, state);
        }

        public void FireProjectile(Vector2 aimDirection, ReplicateState state)
        {
            Vector2 force = aimDirection * pC.playerMovementConfig.fireForce;
            Vector3 aimDirection = force.normalized;
            float spawnDistance = 1.0f; // Distance from the player's center to spawn the projectile
            Vector3 spawnOffset = aimDirection * spawnDistance;
            Vector3 spawnPosition = transform.position + spawnOffset;
            float angle = Mathf.Atan2(force.y, force.x) * Mathf.Rad2Deg;
            Quaternion rotation = Quaternion.AngleAxis(angle, Vector3.forward);

            NetworkObject nob =
                InstanceFinder.NetworkManager.GetPooledInstantiated(_projectilePrefab, spawnPosition, rotation, true);
            if (!nob)
            {
                Debug.LogError("Projectile prefab is not cached.");
                return;
            }
            BasicRigidbodySync brs = nob.GetComponent<BasicRigidbodySync>();
            if (!brs)
            {
                Debug.LogError("Projectile prefab does not have a BasicRigidbodySync component.");
                return;
            }
            //Spawning the CSP projectile
            InstanceFinder.NetworkManager.ServerManager.Spawn(nob, Owner);
            brs.force = force;
        }

@lucid yarrow if you could provide more details about predicted spawning please and my related questions🙏

There shouldn't be any NRE errors on the FN side. Is something in your replicate null?

This happens when a Client Only spawns a CSP Projectile, using :

 public void Fire(Vector2 force)
        {
            Vector3 aimDirection = force.normalized;
            float spawnDistance = 1.0f; // Distance from the player's center to spawn the projectile
            Vector3 spawnOffset = aimDirection * spawnDistance;
            Vector3 spawnPosition = transform.position + spawnOffset;
            float angle = Mathf.Atan2(force.y, force.x) * Mathf.Rad2Deg;
            Quaternion rotation = Quaternion.AngleAxis(angle, Vector3.forward);

            if (!InstanceFinder.NetworkManager)
            {
                Debug.LogError("NetworkManager is null.");
                return;
            }
            NetworkObject nob =
                InstanceFinder.NetworkManager.GetPooledInstantiated(_projectilePrefab, spawnPosition, rotation, false);
            if (!nob)
            {
                Debug.LogError("Projectile prefab is not cached.");
                return;
            }
            BasicRigidbodySync brs = nob.GetComponent<BasicRigidbodySync>();
            if (!brs)
            {
                Debug.LogError("Projectile prefab does not have a BasicRigidbodySync component.");
                return;
            }
            brs.SetOwner(gameObject.GetComponent<NetworkObject>());
            InstanceFinder.ServerManager.Spawn(nob, Owner);
            brs.force = force;
        }

this seems like an error from FN Side, I've followed this guide for my CSP projectile : https://fish-networking.gitbook.io/docs/manual/guides/prediction/version-2/creating-code/non-controlled-object

@lucid yarrow , the only thing that differs from the guide is that my CSP uncontrolled object is a rigidbody2D projectile.
so my [Replicate] is not empty, as shown in the guide, since I want to apply some physics :

[Replicate]
        private void Move(ReplicateData rd, ReplicateState state = ReplicateState.Invalid,
            Channel channel = Channel.Unreliable)
        {
            if (!isLocallyAlive)
            {
                if (graphicalObject != null)
                {
                    graphicalObject.SetActive(false);
                }
                return;
            }

            // TODO: Move this to the ScriptableObject
            Vector2 desiredVelocity = force.normalized * 10f;

            ProjectilePredictionRigidbody2D.Velocity(desiredVelocity);
            ProjectilePredictionRigidbody2D.Simulate();
        }

maybe that's the issue ?

If you are calling replicate from OnTick using TickNetworkBehaviour it's really weird you're getting a NRE for a TimeManager reference, since the OnTick callback only occurs by subscribing to the TimeManager.
