[Scripting Question] Give Randomized Items?

[PunkPhantom]

I'm trying to make something in my game that's similar to Pokestops in Pokemon Go, mainly they will give the player 3 or 4 random items a day or twice a day.

What I don't know is how to generate random items. I'm sorry if this is already on the forum/wiki. How do I give the player a random item chosen from a specific selection of items?

You would like to include double or triple items?

No.

  def extractRandomItems
    maxItems=600 #Change 600 to your Item list maximum
    itemsArray=[]
    for i in 1...maxItems+1
      itemsArray[i]=i
    end
    items=[]
    loop do
      tempItem=itemsArray[rand(itemsArray.length)+1]
      items.push(tempItem)
      itemsArray.delete(tempItem)
      break if items.length==4
    end
    return items
  end

If you call this function, it will returns items array. To store each item, you have to refer as follow:

item1=extractRandomItems[0]
item2=extractRandomItems[1]
item3=extractRandomItems[2]
item4=extractRandomItems[3]

TheMaster's answer is very useful and complete. Just to add in the discussion if you need to give an item based on a specific default list of items you could do something like this:

def extractRandomItem
    itemsArray=["POKEBALL","MEGABALL","ULTRABALL"]
    items=[]
    tempItem=itemsArray[rand(itemsArray.length)]
    items.push(tempItem)
    item=items[0]
    $PokemonBag.pbStoreItem(item)
  end

And call it with: "extractRandomItem" so that it will only choose between those three items. Of course this is just a small adjustment of his script.
