get an element from a table in a function.

How to get an element from a table in a función?

for example:

table1 = { 
{-1434, 2668, 55.68 }, 
{-1460, 2669, 55.66 }, 
} 
  
for_,v in pairs ( table1 ) do 
     object = createObject ( 929, v[1], v[2], v[3] ) 
end 
  
function () 
   --get the object created from the table 
end 

anyone can help me please

table1 = { 
{-1434, 2668, 55.68 }, 
{-1460, 2669, 55.66 }, 
} 
  
for_,v in pairs ( table1 ) do 
     object = createObject ( 929, v[1], v[2], v[3] ) 
end 
  
function () 
getElementData(thePlayer,table1)  
end

I don't think so

I want to get the object to then destroy it and use outputChatBox at player.

If you want to get the value from the table, then you must store it into the table first

object_table = {} 
  
--creating and storing the object 
object_table[some_index] = createObject(...) 
  
--destroying the object 
destroyElement(object_table[some_index]) 
object_table[some_index] = nil -- although object no longer exists, its identifier value is still there, so we assign nil to remove that value and free the memory 

[Anubhav]

Here is it:

I Dint tested it.

  
table1 = { 
{-1434, 2668, 55.68 }, 
{-1460, 2669, 55.66 }, 
} 
  
for_,v in pairs ( table1 ) do 
     object = createObject ( 929, v[1], v[2], v[3] ) 
  
  
     function destroyElement() 
getElementData(thePlayer,table1) 
destroyElement(object) 
outputChatBox("Your object is destroyed.",thePlayer,255,255,255) 
end 
  
  

NOTE: if your object is table1 it will destroy it or change the destroyElement(element name you want to destroy)

[DiSaMe]

Anubhav, please, stop, that doesn't make any sense...

[Cocodrilo]

something like this?

table1 = { 
{-1434, 2668 , 55.68 }, 
{-1460, 2669, 55.66 }, 
} 
  
local obj = {} 
  
addEventHandler ( "onResourceStart", resourceRoot, 
      function()  
           for_,v in pairs ( table1 ) do 
                 local object = createObject ( 929, v[1], v[2], v[3] ) 
                 obj [ooob] = object 
                  destroy() 
           end 
      end 
) 
  
function destroy () 
           setTimer(function() 
                   destroyElement(obj[ooob]) 
                   obj [ooob] = nil 
           end, 5000, 1) 
end 
    

i do not understand at all yet

[Spajk]

Could you explain a bit more what you are trying to do?

[Cocodrilo]

Could you explain a bit more what you are trying to do?

That isn't really i want to do.. I just want to know how to get an object created from a table to then call such object in a function..

for this example.. create the object onResourceStart and call the function ' destroy() ' to destroy it after 5 seconds.

[Gallardo9944]

local table1 = { 
{-1434, 2668, 55.68 }, 
{-1460, 2669, 55.66 }, 
} 
  
local table2 = { }  
  
for i,v in ipairs (table1) do 
     local object = createObject(929,unpack(v)) -- create object with your info 
     table.insert(table2,object) 
end 
  
function getObjectFromTable(num) 
  return table2[num] --get the object created from the table 
end 
  
local object1 = getObjectFromTable(1) -- {-1434, 2668, 55.68 } 
local object2 = getObjectFromTable(2) -- {-1460, 2669, 55.66 } 
  

[Cocodrilo]

you don't understand me, or maybe i didn't explain the right way..

i want to do this..

items = { 
{-1434, 2668 , 55.68 }, 
{-1460, 2669, 55.66 }, 
} 
  
addEventandler ( "onResourceStart", resourceRoot, 
      function()  
           for_,v in pairs ( items ) do 
                 local object = createObject ( 929, v[1], v[2], v[3] ) 
                    setTimer(destroy, 5000, 1)            
           end 
      end 
) 
  
function destroy () 
          destroyElement(object) 
end 
   

but that's not possible cuz destroyElement(object) got a wrong element.

I just want to destroy the object from the table 5 seconds after has been created with a function! how to get the object element?

Thank you so much @ Gallardo9944 !

[Gallardo9944]

You're welcome.

Wouldn't it be easier to just pass the object element in setTimer as an argument?

items = { 
{-1434, 2668 , 55.68 }, 
{-1460, 2669, 55.66 }, 
} 
  
addEventHandler ( "onResourceStart", resourceRoot, 
    function()  
        for_,v in pairs ( items ) do 
            local object = createObject ( 929, v[1], v[2], v[3] ) 
            setTimer(destroy, 5000, 1, object)           
        end 
    end 
) 
  
function destroy(element) 
    if (not isElement(element)) then return end 
    destroyElement(element) 
end 

[Gallardo9944]

@Smart, everyone has his own style and way.

[Cocodrilo]

and if i want to change to bindKey instead of setTimer?

items = { 
{-1434, 2668 , 55.68 }, 
{-1460, 2669, 55.66 }, 
} 
  
addEventHandler ( "onResourceStart", resourceRoot, 
    function() 
        for _,v in pairs ( items ) do 
            local object = createObject ( 929, v[1], v[2], v[3] ) 
            --[[ Change to bindKey instead of 
                setTimer(destroy, 5000, 1, object)     
                    ]] 
        end 
    end 
) 
  
function destroy(element) 
    if (not isElement(element)) then return end 
    destroyElement(element) 
end 

[IIYAMA]

bindKey("x","down",function () 
        for _,v in pairs ( items ) do 
            local object = createObject ( 929, v[1], v[2], v[3] ) 
        end 
  
end) 

Btw, this is lagg, creating for every object a timer......

        for _,v in pairs ( items ) do 
            local object = createObject ( 929, v[1], v[2], v[3] ) 
            --[[ Change to bindKey instead of 
                setTimer(destroy, 5000, 1, object)     
                    ]] 
        end 

[Cocodrilo]

bindKey("x","down",function () 
        for _,v in pairs ( items ) do 
            local object = createObject ( 929, v[1], v[2], v[3] ) 
        end 
  
end)

                    ]] 
        end 

mm.. i don't want to create object with a timer, the objects are created when the resource starts. So I wanna destroy them after have been created with a bindKey.

This works:

items = {  
  
{ -1432.12890625, 2672.3349609375, 55.691806793213 }, 
{-1428.2822265625, 2665.9150390625, 55.6875 }, 
  
} 
  
addEventHandler ( "onResourceStart", resourceRoot, 
    function() 
        for _,v in pairs ( items ) do 
            local object = createObject ( 929, v[1], v[2], v[3] ) 
            setTimer(destroy, 5000, 1, object)           
        end 
    end 
) 
  
function destroy(element) 
    if (not isElement(element)) then return end 
    destroyElement(element) 
end 

But i want to do something like this:

items = {  
  
{ -1432.12890625, 2672.3349609375, 55.691806793213 }, 
{-1428.2822265625, 2665.9150390625, 55.6875 }, 
  
} 
  
addEventHandler ( "onResourceStart", resourceRoot, 
    function() 
        for _,v in pairs ( items ) do 
            local object = createObject ( 929, v[1], v[2], v[3] ) 
            setTimer(destroy, 5000, 1, object)           
        end 
    end 
) 
  
function destroy(element) 
    if (not isElement(element)) then return end 
        bindkey ( player, "x", "down", function() 
        destroyElement(element) 
        end) 
end

Yes! Thank you so much

[DNL291]

You're welcome.

But, keep in mind that the onResourceStart event is called only when a resource is started. Therefore, it will not be called when a player join the server, in that case, you can use onClientResourceStart instead and change the code to the client-side. Or you can use the onPlayerJoin event.
