Variable question

[Snoozy]

Hey now I'm currently working on my business system which is built together with a interior system I got, now I got this problem since the loading of the business and the interior is in two seperate files, I'm saving the interiors like in a variable similar to this:

IntInfo = {} 
-- Later in code 
IntInfo[idx] = {} 

But then when I try and use IntInfo in my business loading lua it doesn't seem to work, it errors me like that the output from the IntInfo in that file just equals a ?

Is there some other way you should do this or what is going on?

If you need to see more code or anything then just ask me

[karlis]

didnt really get what you mean, show full error message

[qaisjp]

He wants to transfer a variable from one resource to another.

[karlis]

oh, imo

  
setElementData(getRootElement(),"dataname",data) 
getElementData(getRootElement(),"dataname") 
  

is a brilliant way.

[Snoozy]

Oh well it seems like the variables wasn't even the problem lol, but yea karlis the problem with that is that I would have to like call all the datanames like int(IDhere)_nameofthething ? Else it wouldn't work cause I got a lot of interiors not just one?

[karlis]

just send the table as data then

[qaisjp]

I forgot about element data. I was gonna say exports.

[Snoozy]

What you mean by sending the table as data? Care to explain a bit cause I don't really get it.

[karlis]

  
intInfo={} 
intInfo[1]={} 
... --and so on 
setElementData(getRootElement(),"dataname",intInfo) 
  

[Snoozy]

Would that single setElementData transfer all the other IntInfo[1]={} also? Or would I have to make one for each, also would it then transfer everything inside like IntInfo[1].X and IntInfo[1].Y in that one elementdata?

[qaisjp]

if you do intInfo, it also sends all it's'children' so, it would transfer everything (IntInfo[1] .. IntInfo[2].Y and soo on..)

[karlis]

yes, it would be advisable to don't have it too big(multidimensional arrays with 1000+keys per dimension can cause trouble.)

[Snoozy]

how would I then use getElementData to get it all out and work as intinfo and all that

[karlis]

how would I then use getElementData to get it all out and work as intinfo and all that

  
intInfo=getElementData(getRootElement(),"data name") 
--now you can access everything that is stored inside that table, even other tables. 
  

[Snoozy]

I'm having this one error that I can't seem to fix, when I get to the business and press R it gives me the error:

[2011-05-26 17:51:10] ERROR: boulevard\business\server.lua:56: attempt to index field '?' (a nil value) 

The line is:

setElementPosition (source,IntInfo[bizInfo[idx].Interior].X,IntInfo[bizInfo[idx].Interior].Y,IntInfo[bizInfo[idx].Interior].Z,true) 

[karlis]

you need to sync both BizInfo and intInfo then.

[Snoozy]

What you mean by syncing them since the BizInfo is created in that lua anyways and shouldn't be any problems with it since it's used another place in the script where it is loaded without having to set that ones elementdata if that's what you mean?

[karlis]

well, you used so much tables inside a tables leading a key to another table inside a table with a key to another double table that i got confused...

anyway, that error means some of the tables inside tables are not created

[Snoozy]

Well yeah it gets confusing when your dealing with tons of tables inside another tons of tables but I'm pretty sure that it's not the BizInfo cause it's used like 2 lines up where its used to check distance between player and the location of the business and it outputs that it's found and so on. With the IntInfo I did following: (maybe I've done something wrong)

IntInfo = {} 
function loadInt() 
    local interior = mysql_connect("******", "******", "*****, "******") 
    if (interior) then 
        local maxi = mysql_query(interior,"SELECT * FROM interior") 
        if (maxi) then 
            maxin = mysql_num_rows(maxi) 
            if (maxin) then 
                for idx=0, maxin do 
                    query = "SELECT * FROM interior WHERE InteriorID = '"..idx.."'" 
                    result = mysql_query(interior,query) 
                    IntInfo[idx] = {} 
                    if (result) then 
                        row = mysql_fetch_row(result) 
                        if (row) then 
                            IntInfo[idx].ID = row[1] 
                            IntInfo[idx].X = row[2] 
                            IntInfo[idx].Y = row[3] 
                            IntInfo[idx].Z = row[4] 
                            IntInfo[idx].Interior = row[5] 
                            IntInfo[idx].Name = row[6] 
                            outputServerLog("Loaded Interior -"..row[6].."-") 
                        end 
                    end 
                    mysql_free_result(result) 
                end 
            end 
        end 
    end 
    mysql_close(interior) 
    setElementData(getRootElement(),"IntInfo",IntInfo) 
end 
setTimer(loadInt,500, 1) 
  
 

at end I do the setelementdata thing as shown above.

Now in the business code:

IntInfo = getElementData(getRootElement(),"IntInfo") 
function Enter(source,key,keystate) 
    if keystate == "down" then 
        if getElementData(source,"BizEntered") == 0 then 
            for idx=1, maxBiz do 
                x,y,z = getElementPosition(source) 
                if getDistanceBetweenPoints3D(x, y, z, BizInfo[idx].SpawnX, BizInfo[idx].SpawnY, BizInfo[idx].SpawnZ) <= 1 then 
                    outputChatBox("24/7",source) 
                    setElementPosition(source,IntInfo[BizInfo[idx].Interior].X,IntInfo[BizInfo[idx].Interior].Y,IntInfo[BizInfo[idx].Interior].Z,true) 
                    setElementInterior(source,IntInfo[BizInfo[idx].Interior].Interior) 
                    setElementData(source,"BizEntered",idx) 
                else 
                    outputChatBox("Not in range of any biz",source) 
                end 
            end 
        else 
            if getDistanceBetweenPoints3D(x,y,z,IntInfo[BizInfo[getElementData(source,"BizEntered")].Interior].X,IntInfo[BizInfo[getElementData(source,"BizEntered")].Interior].Y,IntInfo[BizInfo[getElementData(source,"BizEntered")].Interior].Z) <= 3 then 
                setElementPosition(source,BizInfo[getElementData(source,"BizEntered")].SpawnX,BizInfo[getElementData(source,"BizEntered")].SpawnY,BizInfo[getElementData(source,"BizEntered")].SpawnZ,true) 
                setElementData(source,"BizEntered",0) 
                setElementInterior(source,0) 
            end 
        end 
    end 
end 

[karlis]

don't think you can use mysql node as an key, and btw fix first code, one quote is missing

[Snoozy]

What you mean by not being able to use a mysql node as an key? I'm just saving information from mysql onto a table? Sorry but i'm not really getting it

[karlis]

nvm, interior and Interior isn't the same, anyway, i don't see where is Interior defined?

[Snoozy]

Mhm does two tables doens't work together, like when you cross the information? I just did some debugging and found this problem:

outputChatBox(IntInfo[1].X,source) -- WORKING 
                    outputChatBox(IntInfo[idx].X,source) -- WORKING 
                    outputChatBox(IntInfo[BizInfo[idx].Interior].X,source) -- NOT WORKING 
                    outputChatBox(IntInfo[int].X,source) -- NOT WORKING 

which shows that the ones where you like use the information from BizInfo into IntInfo does not work and that's what makes the error?

[karlis]

try splitting it into few variables, and adding up the tree step by step

[Snoozy]

what you mean? Could you like try and explain it a bit more in details?

Cause splitting both in variables then you can't like combine them afterwards?
