How Can I Trigger a Server Function With User-Input?

Hello,

Happy new year all. I am new in network gaming and there is an issue that i cant understand the logic. The question is this;

For example I want to make a server authoritative game and in this game I want to trigger a function which is calculating a random number and returning it to user when user clicks a button. How can i write this code in playfab with c#? What i need to write to server side code and what i need to write to client side code to communicate with each other?

This kind of example will be very helpful to me to understand network gaming communicating process. Thank you.

I am not sure if your case needs an external server, but for generating an random number, you can simply try to make use of Cloud Script. Cloud script is a powerful feature of PlayFab that can handle most of your server side needs.

  1. Write random number generator in Cloud Script, upload to PlayFab and make it live;
  2. Bind the PlayFabClientAPI.ExecuteCloudScript function with the Button;
  3. Click the button to trigger the function and you can receive generated number in OnSuccessCallback;

You may notice the FunctionParameter in the ExecuteCloudScriptRequest, this is a variable that can be passed to the Cloud script, as a result, you can pass something like random seed for custom random generation.

Implementing a custom external server is already beyond our support scope and this forum is for helping users solve PlayFab related issue. As I have mentioned, your requirement can be fulfilled by Cloud Script, but you can implement a listening port for HTTP requests on your server. Cloud Script is based on V8 JavaScript engine, you can look for official documentation if you are interested.

As i know, PlayFab also have servers for deploying our server executables. So there is no need to rent an external server for our server builds. I just want to know which APIs i need to use in client side code to trigger a server builds code for processing a task in PlayFab server.
