element count

[DakiLLa]

hey all

how can i count elements of a specified type on server ? something like this: i have a number of objects but i dont know how many of them i have. How to count them?

#amountOfObjects=getElementsByType("object") 

The getElementsByType function should return a table. And # counts how many indexes a table has.

#amountOfObjects=getElementsByType("object") 

The getElementsByType function should return a table. And # counts how many indexes a table has.

Your example doesn't make any sense. It's

amountOfObjects=#getElementsByType("object")

ehm guys..one problem here.. i'm getting something other than amount of objects

addCommandHandler ( "test", 
    function (  ) 
        local objects = getElementsByType ( "object" ) 
        objAmount = #objects 
        for k,object in ipairs (objects) do 
            if getObjectModel (object) == 649 then 
                outputChatBox ( "We have "..objAmount.." objects" ) 
            end 
        end 
    end 
) 

if it's (for example) 4 objects i have next:

We have 805 objects

We have 805 objects

We have 805 objects

We have 805 objects

can you fix my mistakes ?

Kinda bad mistake of mine indeed lol...

Anyway, DaK, put "break" (without the quotes) in the line after outputChatBox. Should help.

ok, thx, it outputs only one message now. But another problem: my example counts all objects on server (thats why i have ~800 objects ) , not only objects with ID 649.

How to count objects only with current id?

i have getObjectModel line but it placed in wrong place i think.

I already wondered what that for loop was for.

addCommandHandler ( "test", 
    function (  ) 
        local objects = getElementsByType ( "object" ) 
        local i=0 
        for k,object in ipairs (objects) do 
            if getObjectModel (object) == 649 then 
                i=i+1 
            end 
        end 
        outputChatBox ( "We have "..i.." objects with ID 649" ) 
    end 
) 

This should output the amount of objects with ID 649.
