Increase/Decrease chances of getting an item

[AsakuraHao2004]

This idea just occured to me, so I thought I'd share it. First off, all you need is a pretty basic understanding of variables.

Lets say you have a CBS, and theres a monster that drops an item, however, the chances of getting this item is very rare. So what we could do is

<> Set Variable "Rare Item Drop" to a random number between 1-5
<> Branch if variable "Drop Item" is 1
      <> Add item "Rare Item" +1
      <> wait 0.1 sec
      <> Set Variable "Rare Item Drop" to 0
<> Else Case>

<> End

(The wait and Set Variable to 0 will set it so that you can use the variable again)

Now, there's a 1-in-5 chance of dropping that item will occur. For even higher rarity, you can set the random number range to even higher levels. I don't reccomend going over 20. Also, instead of making an else case, you could do this:

<> Set Variable "Item Drop" to a random number between 1-10
<> Branch if variable "Drop Item" is 1
      <> Add item "Rare Item" +1
      <> wait 0.1 sec
      <> Set Variable "Rare Item Drop" to 0
<> End

<> Set Variable "Item Drop" to a random number between 1-10
<> Branch if variable "Drop Item" is 2
      <> Add item "NON-Rare Item" +1
      <> wait 0.1 sec
      <> Set Variable "Rare Item Drop" to 0
<> End

And so on. This will make it so that a monster usually drops a regular item, but might drop a rarer item occasionally. You can also put in different items several times over (to increase chances of getting it), or leave a few blank.

A good way to set up, would be to have about 10 numbers set. make 5-6 numbers blank (so the monster wont drop anything sometimes), have 3-4 of the numbers with a "normal" item (the same, or different ones), and only have the rare item assigned to 1 number. This is a good range that will probably provide fair item span.

Hope this helps

Hmm. Concievably, this could also be applied to the DBS using the same code; you'd just need to activate it by the monster having no HP. I think I'll play around with that.

Nice tutorial, well-written and understandable. The only thing is, if you had a CBS, you'd probably already know how to code an item drop system

Your code is kinda screwy. You would not need to re-randomize the number when dealing with the non-rare stuff.

Here is another way to do it probably involves less code:

<> Variable Operation [001: Item Drop] Set, Rnd 1-10
<> Branch if Var [001: Item Drop] is 5 less
<>  Branch if Var [001: Item Drop] is 1
<> Change Items: Rare Item +1
<>
<> Else Handler
<> Change Items: Non-rare Item +1
<>
:  End
<>
:  End
<>

The "inside" branch has the else condition. After seeing if the items drop is less then 5 (1-5 means that something will drop) we see if it exactly 1. If it is, we give the rare item. If not, we give the non-rare item.

Avoids having to copy a bunch of code a lot of times.

Nice idea, though you would need a CMS for it. In the DBS after the last enemy dies the battle ends, so there is no time for custom code.

Worked for me.

I'm kinda weary of using your method, because I used a smiliar one for something else, which caused massive problems. And that method would really limit custimization, although it is effective for decreasing/increasing chances.
