# fortran mmo-project client
|
||||
|
||||
pipes suck and dont work, try wrapping the libdill library instead.
|
||||
The client uses the same mod_dill library from the [tcp-client-server demo](https://github.com/modern-fortran/tcp-client-server)
|
||||
|
||||
Also the [raylib library](https://www.raylib.com/). I have generated a fortran interface for the functions neccisary for a minimal client. The module is using the new C interop interface implemented in the 2018 spec which makes it fairly easy to create a interface between a C library and Fortran.
|
||||
|
||||
One thing to note in here is that Fortran does not actually have unsigned values, so you have to use normal integers and use the `-fno-range-check` flag to tell the compiler that you know what you are doing. Otherwise the colors would not look correct.
|
||||
|
||||
For simplicity I have made it so that the login credentials are passed in through the command line instead of a GUI interface.
|
||||
|
||||
Fortran has the ability to use the OOP paradigm so I wanted to show that off here with the player module.
|
||||
|
||||
The player is able to store their own name, position, and color. There is an interface to allow the client to sync the camera and send the position to the server.
|
||||
|
||||
You can also see the json library shine with this implementation. It made it trivial to process the json array that was built and sent from the server.
|
||||
|
||||
The only other thing to note is the weird modulo chunk here:
|
||||
|
||||
``` fortran
|
||||
time = get_time()
|
||||
if (modulo(time, 1.0) .ge. 0.58_c_double) then
|
||||
if (player_updated) then
|
||||
players = me%move()
|
||||
else
|
||||
players = me%ping()
|
||||
end if
|
||||
end if
|
||||
```
|
||||
|
||||
This is because there is not a good way to asyncronously send a call to the server, so I have this hack which uses the current tick time from raylib and run the update/ping function every 500 milliseconds or so.

# server

|

The server implementation is as simple as I could make it.
|
||||
|
||||
I found a library called mod_dill from the [tcp-client-server demo code](https://github.com/modern-fortran/tcp-client-server) from a book on modern fortran. This gave me a simple TCP interface to send and recieve "messages".
|
||||
|
||||
Originally I had tried saving formatted fortran data into a string and trying to send that, but when you convert the fortran string to a c-string it oftend became garbled and unusable when sent through the tcp connection so I stopped using that method.
|
||||
|
||||
I found in [fpm](https://fpm.fortran-lang.org/index.html) [official registry](https://registry-frontend.vercel.app/) a json library which would make it *much* easier to deal with data transfer.
|
||||
|
||||
The simplest way to implement the communcation between the server and clients would be a series of tcp requests and responses.
|
||||
|
||||
- request
|
||||
- int :: request_type
|
||||
- ping # 0
|
||||
- login # 1

||||
- double :: x_pos
|
||||
- double :: y_pos
|
||||
|
||||
For each request, the same response is returned with is a list of the logged in users.
|
||||
|
||||
The commands that can be sent to the server are logging in, logging out, moving, and the default "ping" which is essentially a noop from the servers pov.
|
||||
|
||||
The server uses the same sqlite library as the [www implementation](../www/README.md).
|
||||
|
||||
The server loop is:
|
||||
1. listen for connection
|
||||
2. read message from client
|
||||
3. convert c string to fortran string
|
||||
4. convert the fortran string to a json object
|
||||
5. run the command from the json object
|
||||
6. create a json array of the logged in users and send to client.

I found a library to interface with the sqlite library I will store the username, password, and other information about.

|

The issue is that fortran does not have a built in cryptographic hash library nor is it in the stdlib, I did find a implementation of the [SM3](https://github.com/zoziha/SM3-Fortran/tree/main) hash which is cryptographically sound, and have used that.
|
||||
|
||||
If this were to be used in the real world I would prefer to use [bcrypt](https://en.wikipedia.org/wiki/Bcrypt) as it is the most common password hashing algorithm.
|
||||
The issue is that fortran does not have a built in cryptographic hash library nor is it in the stdlib. So it has been ommited for this implementation, although it should not be in a real world situation.
|
||||
|
||||
The implementation does not work well with existing systems since you have to convert from fortran strings to c strings and it returns an integer array of c strings which has to be converted back into fortran strings.

Can you tell the difference between all of them? theyre all doing almost the same thing, but they are slightly different. And some ways seem to work fine until you try to write to output. Or if you use a speicifc operator on one tyep, you cant on the other.

Also the hex to integer just doesnt work at all so I had to implement one myself...
|

|

The next issue was SQL. There is no native interface with Fortran and SQLite3 (which is the databse I am using for this project). The only "native" soluition would be to use the `execute_command_line` subroutine and then read the output from a temp file in order to do sql operations.
|
||||
|
||||
So I looked around on the internet for a different solution.
|
||||
|
||||
To my supprise I found a project that aims to add a package manager to Fortran called [fpm](https://fpm.fortran-lang.org/index.html)
|
||||
|
||||
One of the libraries that was available was a sqlite implementation. So I decided that since I was already a month behind schedule I would stop being so strict with my rule of wanting to use "100% vanilla Fortran" and start using this package manager.
|
||||
|
||||
The Fortran package manger is actually pretty fantastic. It has a similar feel to [npm](https://www.npmjs.com) if you have expereince with that.
|
||||
|
||||
Creating a new project is as easy as `fpm new Project_Name` and adding libraries can be done by editing the .toml file and running `fpm build`
|
||||
|
||||
The specific library I found for sqlite is [fortran-sqlite3](https://github.com/interkosmos/fortran-sqlite3).
|
||||
|
||||
So I finished up the last few things in the implementation and called it complete.
