[HELP] change indexes in a table

[opnaiC]

Hello,

I am scripting a new chat and the stuff I scripted is working. But now I have a problem. In my chat I am printing the first 13 messages in dxDraw. But now I want all indexes to +1, so if there come a 14th message it gets visible.

local offset = 14

function drawChat()
    for i, v in ipairs (chatbox) do
	    if (i < offset) then
	        exports.login:dxDrawBorderedText(v, 36, (210 - ((offset-i)*15)), 411, 210, tocolor(255, 255, 255, 255), 1.00, "default-bold", "left", "top", false, false, false, false, false)
        elseif (i == 14) then
            --what to add ? I want all index to +1, so the new message will get the first index		
        end		
	end
end
addEventHandler ("onClientRender", root, drawChat)

chatbox[#chatbox + 1] = newItem

#chatbox returns the table lengte.

 

See table.insert for inserting on to the first item.

table.insert(chatbox, 1, newItem)

This is how you can insert items in to the first index and move the rest of the items up.

Tried this but the game starts freezing. ... Maybe because auf the eventHandler.... I can´t find a solution.

You are filling your table with infinity items.

elseif (i > 13) then
	local value = chatbox[i] -- get the value
	chatbox[i] = nil -- delete the item
	table.insert(chatbox, 1, value) -- re-insert
end

It is also not working correctly. I show you a picture maybe you can help me.

In the output you can see the text and then the index number. So I want the text with the index 1 to disappear (it should be in the table but not visible). Now I want the new message to output where you can see the text with the 13th index number. The other outputs should move up. BUT the old output should save, so I have it easier to do a scroll function later.

elseif (i > 13) then
	table.remove(chatbox, 1)-- delete the first item, and move all higher items one down.
end	

I thought you wanted to insert items at the beginning.

I know I did it now, when you posted this message . Thank you. Its working. So, I have to save the message that got deleted in another table if I want to do a scroll function and return them to the table, right ?

 

Like that:

elseif (i > 13) then
		    table.insert (chatboxBuffer, v[1])
		    table.remove (chatbox, 1)
end

yea you can do that.

 

Or just using 1 table. And start looping at a different index.

for i=math.max(#chatbox - 13, 1), #chatbox do
  local v = chatbox[i]
end

(not sure if you have to use: - 12, - 13 or - 14 to accomplish this)
