I receive the data which are X, Y, Z position and X, Y, Z rotation by Using UDP.
I get the data(x,y,z position and x,y,z rotation) from realtime simulation.
It is communicated by UDP/IP.
I used the code by la1n.(simple udp implementation (send/read via mono/c#) - Unity Engine - Unity Discussions)

This code is simulation code and It is written by Lua Script.

  socket = require("socket")
  print(socket._VERSION)

  function dataListener:post( t )

    local XPos = ship.rb:getPosition():x()
    local YPos = ship.rb:getPosition():y()
    local ZPos = ship.rb:getPosition():z()
    local XXPos = math.floor( XPos * 1000 + 0.5 ) / 1000
    local YYPos = math.floor( YPos * 1000 + 0.5 ) / 1000
    local ZZPos = math.floor( ZPos * 1000 + 0.5 ) / 1000
  
    local XRot = ship.rb:getRotation():x()
    local YRot = ship.rb:getRotation():y()
    local ZRot = ship.rb:getRotation():z()
    local XXRot = math.floor( XPos * 1000 + 0.5 ) / 1000
    local YYRot = math.floor( YPos * 1000 + 0.5 ) / 1000
    local ZZRot = math.floor( ZPos * 1000 + 0.5 ) / 1000

    udp=socket.udp();
    udp:setpeername("127.0.0.1",8051)
    udp:send(string.format("%f; %f; %f; %f; %f; %f", XXPos, YYPos, ZZPos, XXRot, YYRot, ZZRot));
  end

I have worked for 3 hours. But Whenever I debug, Errors occur and It doesn’t work…

I’m not entirely sure what the question is but it sounds like you want to know how to put the data you are receiving into the transform.

First you want to split the strings using ; as your token. Then you want to parse them into floats using float.Parse.
You can then assign them to the transform.

Take a look at this for splitting: Divide strings using String.Split - C# | Microsoft Learn

Parsing like so:

float value = float.Parse("123.5");

Setting pos and rotation:

Now put it all together :wink:

Thank you. The process is split->parse->matching, right??
