[Resolved] Random Selection

[Mac]

What would be the code to ask for a random item, weapon or armour in a certain area.... e.g.

Random Item(choice of random item id)

rand_item.id(1, 2 ,3 ,4 ,5 ,8, 20)

Hope thats understandable.

item = $data_items[rand($data_items.size)]
weapon = $data_weapons[rand($data_weapons.size)]
armor = $data_armors[rand($data_armors.size)]

Will give you one of those at random. If you only want one within a range of ids, try:

id_arr = [1, 2, 3, 4, 5, 8, 20]
item = $data_items[id_arr[rand(id_arr.size)]]

Hmmmm how would i go about calling upon it just by Call Script, without embedding it as a script?

id_arr = [1, 2, 3, 4, 5, 8, 20]
$game_party.gain_item(id_arr[rand(id_arr.size)], 1)

I just get a syntax error for calling it. Sorry -_-

I tried to plug it in and got a syntax error too. I broke it down into more lines and it worked though:

id_arr = [1, 2, 3, 4, 5, 8, 20]
item_gained=id_arr[rand(id_arr.size)]
$game_party.gain_item(item_gained,1)

I prefer to use a method in the Array class for something like this.

class Array
  def random
    return self[rand(self.size)]
  end
end

Just add that in your scripts somewhere.

So if you wanted to gain a random item from a list of item ids

ids = [a, b, c, d]
$game_party.gain_item(ids.random, 1)

Simple, but effective.
