Saving GRIDLIST

[HUNGRY:3]

hello so i made a chat in the grid list...

i want to save the chat like when i type hi

and then i reconnect i find the "hi" in the grid :3

so how to do it?

Use XML who will be saved when someone type something (don't saved all chat only save the last 30 message for exemple.

Then load it when u connect on the server.

thank you..

but how to save the only 30 last msgs?

Put them in a table and then insert messages like:

local messages = {} 
table.insert(messages, 1, {playerName, message}) -- Insert a message into table at first position. 
if #messages > 30 then 
    table.remove(messages) -- Remove last one 
end 

MySQL is much more faster and convenient than XML. Maybe you could use it and you wouldn't need to save only 30 last messages. You could make custom logs. And if you still want to fetch only 30 messages, you could easily fetch latest 30 from MySQL database by using LIMIT.
