Multiplayer Help

Hi I have recently been trying to make an online game so I went and read the networking tutorial on the wiki, but it didn't explain why you really have to format the string before sending from the server. Why is it necessary? Any help anyone could provide would be helpful

If you're referring to lines like this one

Code: Select all

local dg = string.format("%s %s %d %d", entity, 'at', 320, 240)

that's equivalent to

Code: Select all

dg = entity.." at "..320.." "..240

The point is to turn it into a single string like

Code: Select all

"*entity* at 320 240"

I would recommend having a look at enet for networking.

Because string is basically array of bytes which is easy to work with: to compose on sender side and to process on receiver side using standard string libraries. You can set up communication without using strings and using your own encode-decode format, but your data is going to be a pack of bytes anyway.

I have a question. If I format the string, will it be sent as a string? Can I send packages as raw bytes to increase bandwidth?

Thank you guys so much I was getting really confused

Yes.

Can I send packages as raw bytes to increase bandwidth?

No.

You can only send strings, because what's sent is the contents of the string, and they're sent as raw bytes.

Another easier way, in my opinion is having in loop through the data, finding every space, then separating the works/numbers/characters and then putting them into a table in order.

Code: Select all

for i in string.gmatch(receivedData, "%S+") do
	table.insert(command, i)
end

Then I use something like:

Code: Select all

if command[1] == "dog" then
print("cat")
end
command = {}

Just I little thing I found out. But the other way is great too, just never figured out how to use it lol.
