P3 Sends: Skills, Moving, Combat

As you can see they all send data in a different order. How does the server know to execute the function that handles Moving if that is sent first and so on for the rest of them?

-------CLIENT--------
message = "M" .. tostring(move)
socket:sent(message) --or whatever is the name of the function

-----------SERVER--------
message = socket:receive() --or whatever is the name of the function
if message:sub(1,1) == "M" then
  --handle movement
elseif message:sub(1,1) == "C"
  --handle combat
elseif message:sub(1,1) == "S"
  --handle skills
end

I think we misunderstood each other by different perception of what "order" is. What I mean by order refers to all packets sent by a client, no matter what is their content.

So, if I understand, you want to know how to detect the type of a message?

Well, you can do sth like this:

Code: Select all

-------CLIENT--------
message = "M" .. tostring(move)
socket:sent(message) --or whatever is the name of the function

-----------SERVER--------
message = socket:receive() --or whatever is the name of the function
if message:sub(1,1) == "M" then
  --handle movement
elseif message:sub(1,1) == "C"
  --handle combat
elseif message:sub(1,1) == "S"
  --handle skills
end

Sekaru wrote:Oh! That clears it up quite a lot!

Could you explain "message = "M" .. tostring(move)" this line though, is that what gives (1,1)? (not really sure here).

------------CLIENT
message = {}
message.type = "movement"
message.value = 153
message.text = "something, something"
text = serialize(message)
socket:send(text)

-----------SERVER
text = socket:receive()
message = deserialize(text)

if message.type == "movement" then
  --you know what to do
end

Sekaru wrote:Thanks a lot! I've got everything working (I think). I've downloaded Serpent and figured out how to serialize (serpent.line(message)), but I can't figure out how to deserialize, do you happen to know the name of the deserialization function?

local serpent = require("serpent")
local a = {type = "move", x = 153, y = 356}

local x1 = serpent.dump(a)
local x2 = serpent.line(a)
local x3 = serpent.block(a)

local fun, err = loadstring(x1)
if err then error(err) end
local copy = fun()

function love.draw()
	love.graphics.print(string.format("%s\n\n%s\n\n%s\n\n%s", x1, x2, x3, copy.type), 0, 0)
end

Sekaru wrote:Oh okay so you use all three.

And do you always have to do the "string.format("%s\n\n%s\n\n%s\n\n%s")" bit for everything you send over or is that specific to that example?
