Get started

1. Install StrideNet NuGet package to your Stride project.

2. In Stride Editor create empty entity on scene and attach Network->NetworkManager and NetworkSpawner components to it.

3. Create your player entity on scene and attach Network->NetworkEntity component to it. Create prefab and save it.

Player script sample

namespace Sample
{
    public partial class Player : NetworkScript
    {
        public float Speed { get; init; }

        [DataMemberRange(0,1, 0.01, 0.1, 5)]
        public float Interpolation { get; init; } = 0.5f;

        [NetworkVariable(SendMode = MessageSendMode.Unreliable)]
        private Vector3 _position;

        public override void NetworkStart()
        {
            Log.Info($"NetworkId: {OwnerId}, IsLocalPlayer: {IsOwner}");
        }

        public override void Update()
        {
            if(IsClient)
                Entity.Transform.Position = Vector3.Lerp(Entity.Transform.Position, Position, Interpolation);

            if (!IsOwner)
                return;

            float horizontal = (Input.IsKeyDown(Keys.A) ? -1f : 0) + (Input.IsKeyDown(Keys.D) ? 1f : 0);
            float vertical = (Input.IsKeyDown(Keys.S) ? -1f : 0) + (Input.IsKeyDown(Keys.W) ? 1f : 0);

            Vector2 input = new(horizontal, vertical);
            UpdatePositionRpc(input);
        }

        [NetworkRpc]
        private void UpdatePosition(Vector2 input)
        {
            float deltaTime = (float)Game.UpdateTime.Elapsed.TotalSeconds;
            Entity.Transform.Position += Entity.Transform.WorldMatrix.Up * Speed * input.Y * deltaTime;
            Entity.Transform.Position += Entity.Transform.WorldMatrix.Right * Speed * input.X * deltaTime;
            Position = Entity.Transform.Position;
        }
    }
}

4. Add prefab to spawnable prefabs list in NetworkSpawner component.

5. Now create new script that will start NetworkManager and spawn players.

Code sample

namespace Sample
{
    public class GameStartup : SyncScript
    {
        public NetworkManager NetworkManager { get; init; }
        public NetworkSpawner Spawner { get; init; }
        public Prefab PlayerPrefab { get; init; }

        public override void Start()
        {
            NetworkManager.ClientConnectedToServer += NetworkManager_ClientConnectedToServer;
            NetworkManager.ServerStarted += NetworkManager_ServerStarted;
        }

        private void NetworkManager_ServerStarted(object sender, System.EventArgs e)
        {
            if(NetworkManager.IsHost)
                Spawner.SpawnEntities(PlayerPrefab, ownerId: 0);
        }

        private void NetworkManager_ClientConnectedToServer(object sender, ServerConnectedEventArgs e)
        {
            Spawner.SpawnEntity(PlayerPrefab, e.Client.Id);
        }

        public override void Update()
        {
            if (Input.IsKeyDown(Stride.Input.Keys.D1))
                NetworkManager.StartHost();

            if (Input.IsKeyDown(Stride.Input.Keys.D2))
                NetworkManager.StartClient();
        }
    }
}

6. Attach this component to a entity on a scene and assign properties in editor.

7. Build game and see result.

For this sample, to start server press 1, to start client press 2.
