Random Treasure

I'm trying to create a code that will generate a random treasure from a pool of different treasures. Specifically, I'd like to be able to place a symbol or chest in a square and have a random weapon in it. Can anyone help?

You could do something similar to this...
switch(pick("Gold","Cheese","Swiss Cheese","Ancient sandwich of unimaginable powers"))
   if("Gold")
      //do stuff
   if("Cheese")
      //do stuff
   if("Swiss Cheese")
      //do stuff
   if("Ancient sandwich of unimaginable powers")
      //do lots of stuff because its important


Thats probably not the best way to do it, especially if you want to have it pick different treasures more often than others. For that you would have to ask someone more experienced. I'm sure I can do it, but it would take some time that I don't have at the moment, and if you want to do that it would be better for you to do it yourself so you have the experience.

Why not just directly use pick() on a list of specific outcomes...? 
#define otypesof(x) (typesof(x)-x)
//---
var/list/paths = otypesof(/obj/item/treasure)
var/random_treasure_path = pick(paths)
new random_treasure_path(location)

Yeah do that one, lol

Could you explain it a little more, I think I get it but I'm not sure.

Well, that is simple code... what is confusing you? The #define? Usage of pick()? new()?

The #define is all I should have said that in the other post.

typesof() returns a list of the child types, INCLUDING the main, parent type. This means if you have these paths: 
obj/item
   box
   apple

typesof(/obj/item) will return: 
list(/obj/item,/obj/item/box,/obj/item/apple)


Now, very frequently, including these times, you won't actually need or use the base type (/obj/item), and need to skip it. You can quickly do it with the - operator: 
typesof(/parent_path) - /parent_path

It will subtract (remove) the parent path from the list typesof() returns. This is where the #define comes in, its just a shorthand for that, so you don't have to manually add a minus and copy the path each time.
Note that this is a short way for convenience, and can be more efficient; since you're using the '-' operator, it creates another list. You can avoid this and only create one: 
var/list/paths = typesof(/parent_path)
paths -= /parent_path

Ah ok thanks, I've used typesof() but never really understood everything about it.

Thanks again
