The wiki has information about how the ability Pickup works. It's not the easiest code to understand and modify.
The list of common items has 18 items in it for a reason, and that reason is that there are 10 different level ranges (1-10, 11-20, etc.) and the game takes
9 items from that list (the one listed next to the appropriate level range plus the next 8 items). Similarly, the list of rare items has 11 items in it because there are 10 different level ranges and the game takes
2 items from that list (the one listed next to the appropriate level range plus the next 1 item).
Changing the lengths of these item lists alone isn't enough.
Code:
for i in 0...[COLOR=Red]9[/COLOR]
items.push(pickupList[itemstart+i])
end
items.push(pickupListRare[itemstart])
items.push(pickupListRare[itemstart+1])
Notice that I coloured in the
9 in my text above, as well as the
9 in the code I just wrote. This is the same number. If you want to take more items out of the common list, you'll need to change this number. Similarly, I coloured in a
2 when I talked about the rare items list, and there are
two items.push lines that mention
pickupListRare. The latter can be a little confusing because it's written differently. Really, you could replace the above code with the following, and it'd work exactly the same and be clearer and easier to modify:
Code:
for i in 0...[COLOR=Red]9[/COLOR]
items.push(pickupList[itemstart+i])
end
for i in 0...[COLOR=Red]2[/COLOR]
items.push(pickupListRare[itemstart+i])
end
There's another line of code a little further down, which says this:
11 is
9 plus
2. If you change the
9 or the
2, you'll need to change the 11 accordingly.
Those are the miscellaneous code changes you'll need. But before that, and most importantly, you'll need to decide on your items and percentages. Why are
9 items chosen from the common list and
2 from the rare list? Well, it's because of this line:
Code:
randlist = [30,10,10,10,10,10,10,4,4,1,1]
This array has 11 numbers in it. As mentioned above, 11 is
9 plus
2. Why not 8+3, or 5+6? That's just how Pickup works in Pokémon games. You can indeed have 8+3 or 10+1 if you want, as long as you change the code accordingly.
Anyway, the game calculates 11 items, and then chooses one of them to be picked up. The 11 numbers in the array are the percentage chances of choosing each item in turn - the last two items each have a probability of 1%, and those two items also happen to come from the list of rare items. You can change how many items you want to calculate (and then randomly choose from those items) by changing this array. For example:
Code:
randlist = [40,20,20,10,4,4,1,1]
I'm still going with
2 rare items here (both 1% chance), which means this array lets me have 6 items from the common list (rather than
9). These probabilities still add up to 100, which is good. Any code which uses the number
9 (see above) should be changed to use 6 instead. Because I choose 6 items from the common list, that means
pickupList only needs to contain 15 items (10 different level ranges, one of which is the first item calculated, plus the next 5 items). The list
can be longer, but it's pointless as the 16th, 17th and so on items can never be chosen. Might as well keep the list only as long as it needs to be.
That's how I decided how many items should be in my lists. Thus I can change the numbers in these lines of code accordingly:
Code:
return if pickupList.length!=18
return if pickupListRare.length!=11
Ultimately, I don't think there's a point to changing how many items are available via Pickup. You can certainly change
which items are available, but given that Pickup by default can choose from 29 different items, surely that's enough to be getting on with?
