ApprovalCheck function might need update on your Wiki

Question

Description

I have downloaded your latest release and try to create a server and a client from scratch based on your Wiki.

    private void ApprovalCheck(byte[] connectionData, uint clientId, Action<uint, bool, Vector3, Quaternion> callback)
    {
        //Your logic here
        bool approve = true;
        //If approve is true, the connection gets added. If it's false. The client gets disconnected
        callback(clientId, approve, new Vector3(0,0,0), Quaternion.identity);
    }

However, the following line

NetworkingManager.singleton.ConnectionApprovalCallback = ApprovalCheck;

complains that “No overload for ApprovalCheck matches delegate 'Action<byte[], uint, NetworkingManager.ConnectionApprovedDelegate>”

Could you give me some hint how to resolve this issue?

Your Environment

• Unity Version: {2018.2.10f1}
• MLAPI Version (2.1.0}

I pulled the default of 64 out of my arse. You can set it to 1 if you want. Lower numbers process messages in larger batches. (Ex: set it to 1, and it will process ALL pending messages once a second). Higher rates will spread the load over frames. Lower numbers thus give higher latency.

64 is nice because it high enough to have low latency and will spread the messages out quite nicley. But it’s also not absurdly high, thus not wasting frame cycles. If your server runs at 1000 fps. There is no point doing network IO in every frame. 64 is still really good in that case.

Just remember, having a high value is only effective up to the framerate. The tickrate becomes this: Math.Min(FRAMERATE, TICKRATE);

Thus, if you run 1 FPS and set the tickrate to 1000. It will still work as if you set the tickrate to 1.

The reason the tickrate option exists is to be able to control the rate without changing the framerate. Changing the framerate could mess with drawing, physics and other things.

Also, the server and client can have different values.

I’m sorry for bothering you, but I’m trying to evaluate the new MLAPI in terms of latency. I need some help on the SendTickrate, ReceiveTickrate and EventTickrate. Assuming we have an update loop of 60Hz, how should I set the above-mentioned variables in a reasonable manner? Should they all have the same value, e.g.: 50? Does the network manager need to be configured in the exact same way with respect to those variables for the server and the client? How did you come up with the default 64?

Thanks
