Another for loop problem, eh...

This time I'm trying to loop through all the obj's in the world, and find out what the "amount" is. Here is the code...

mob/verb
    CheckObjects()
        for(var/obj/S in world)
            usr<<"There are [S.amount] [S]"
        
obj/var
    amount

obj
    Apples
        amount = 1000
<dm>

All help is appreaciated.

I'm not quite sure what you're trying to do here, find the combined value of all apple amounts in the world?

<code>var/combined = 0 for(var/obj/apple/A in world) combined += A.amount usr << "[combined] apples total"</code>

Find the total amount of apple objects in the world?

<code>var/total = 0 for(var/obj/apple/A in world) total++ usr << "[total] apples in the world"</code>

Or what? If you just want to look through all the apples in the world and see what their amount is, I see nothing wrong with the code you've got.

That's exacly what I'm trying to do and its not working. Whenever I click the verb nothing happens. I don't understand what is wrong.

Maybe you never placed any objects on the map. Or maybe you didn't make any new() objects. Objects merely defined in your code are not in the world.

Ooh, right I forgot about that. Haha, I'm not placing any objects on the map, so I guess I'm going to have to use the New() command.

Wait...so is there an easy way to make a new object when starting the world. I think it should loook something like:

world/New()
  new object here


but I'm not sure..

Yeah. 
world
    New()
        ..()  //Very important.
        new /obj (locate(1,1,1))

world 
    New()
        ..()
        new/obj/Apples(1,1,1)


That's what I have. It dosn't give me any errors, but still dosn't work with the for loop.

Because it should be new/obj/apples(locate(1,1,1))

Eh...still dosn't work. Maybe I missed something.

world 
    New()
        ..()
        new/obj/apples(locate(0,0,0))
        
mob/verb
    CheckPrices()
        for(var/obj/S in world)
            usr<<"There is [S.amount] of [S]"
        
obj/var
    amount

obj
    apples
        amount = 1000

Location 0,0,0 doesn't exist, it's null..

Those 3 values represent the x, y and z co-ordinates on the map. If you take a look in the map editor there are 3 numbers next to the map, those are the current co-ordinates the mouse is over.

Yes, I knew that, but then I didn't think it would work because I don't have a world map. Now let me check...aah, my problem was that I didn't have a map. Well thank you all very much, it works! ^_^
