    ExchangeData(    2609    ,    100    ,    2713    ,    1    ,    1)
    ExchangeData(    2609    ,    1000    ,    2714    ,    1    ,    1)

 

and i saw in variable

 

ChangeItemList[ 248    ]=    {    855    ,    600    ,    803    ,    1    }

 

buti still donth understand and i got lost, can some one guide me please

Since the packet sent from client to server when you use the exchange npc contains the item ID, the ChangeItemList table is required as it contains all the valid exchanges and compares the IDs in the packet received to it.

 

You can edit ExchangeData function to contain something like:

 

table.insert(ChangeItemList,{srcID, srcNum, tarID, tarNum})

 

To automaticly make this table for you, then you can just use:

 

ExchangeData( srcID, srcNum, tarID, tarNum, timeNum )

Could you write and example how will be added in an NPC and in the variable i still got lost

Can you explain a more?

 

Would this just be for automatically creating a table for ChangeItemList?

 

How would you implement that? With a new function or with an existing one?

@Covadola

 

U have to add to NPC, and then add that exchange to ChangeItemList in variable.lua.

Warning: Long post below

Spoiler

 

@Billy's script addition made it so that you don't have to change ChangeItemList anymore, by adding the line 

table.insert( ChangeItemList , { srcID , srcNum , tarID , tarNum } )

into the function

function ExchangeData( srcID, srcNum, tarID, tarNum, timeNum )
	if srcID == nil or srcNum == nil or tarID == nil or tarNum == nil or timeNum == nil then
		LG( "npcinit_error", "ExchangeData: Function parameter error!srcID, srcNum, tarID, tarNum, timeNum", srcID, srcNum, tarID, tarNum, timeNum )
		return
	end
	
	Exchange.count = Exchange.count + 1
	
	--兑换数据
	Exchange.srcid[Exchange.count] = srcID
	Exchange.srcnum[Exchange.count] = srcNum
	Exchange.tarid[Exchange.count] = tarID
	Exchange.tarnum[Exchange.count] = tarNum
	Exchange.timenum[Exchange.count] = timeNum
end

in ScriptSDK.lua

 

(like this)

 

function ExchangeData( srcID, srcNum, tarID, tarNum, timeNum )
	if srcID == nil or srcNum == nil or tarID == nil or tarNum == nil or timeNum == nil then
		LG( "npcinit_error", "ExchangeData: Function parameter error!srcID, srcNum, tarID, tarNum, timeNum", srcID, srcNum, tarID, tarNum, timeNum )
		return
	end

	table.insert( ChangeItemList , { srcID , srcNum , tarID , tarNum } )

	Exchange.count = Exchange.count + 1
	
	--兑换数据
	Exchange.srcid[Exchange.count] = srcID
	Exchange.srcnum[Exchange.count] = srcNum
	Exchange.tarid[Exchange.count] = tarID
	Exchange.tarnum[Exchange.count] = tarNum
	Exchange.timenum[Exchange.count] = timeNum
end

in ScriptSDK.lua

 

Now, you can make your NPC, and put in 

    ExchangeData(    2608    ,    100    ,    2682    ,    1    ,    1)

or whatever you want. 

 

 

Now, for my explanation

 

If you wanted to make an exchange function with another character in the map already using the function, it will overlap and won't work.

 

So you have to make your own:

 

Search for: 

function ExchangeData( srcID, srcNum, tarID, tarNum, timeNum )

function SendExchangeData( character, npc )

function InitExchange()

and make your own script, such as:

ExchangeData2
SendExchangeData2
InitExchange2

and then put into NpcSdk.lua

 function MsgProc

		elseif item.func == SendExchangeData2 then
		return SendExchangeData2( character, npc )

next to the original one.

 

Then, you will have 2 exchange NPCs in 1 map.

 

This can be a guide on it's own

Now the question: Is there a better way to do this?

One day? It might seem basic, yet you don't know how to do it, so how is it basic? A lot of people with knowledge started the same, just because they didn't get answers on a forum didn't mean they gave up, they started looking how scripts worked and eventually worked them out or found a way around it. That didn't take one day, it might of took a week even to understand everything completely.

Thanks @Angelix It was more difficult than I thought thanks to @Shako for helping me to solve this problem and @Billy for the table.insert, thank you guys
