|
||
*
|
||
* 元プラグイン:
|
||
* http://himeworks.com/2015/11/more-enemy-drops/
|
||
*
|
||
* == 説明 ==
|
||
*
|
||
* RPGツクールでは、敵に対して最大3つのアイテムドロップを作成できます。
|
||
* 戦闘が終了すると、
|
||
* プレーヤーはこれら3つのアイテムのいずれかを手に入れられます。
|
||
*
|
||
* ドロップを指定する時、'分母'で確率を使用します。
|
||
*
|
||
* 例えば、アイテムがドロップする確率が1/2だった場合、
|
||
* 50%の確率でドロップします。
|
||
* アイテムにドロップする確率が1/3ある場合、ドロップする確率は33.33%です。
|
||
*
|
||
* 残念ながら、このシステムでは、間に確率を設定することはできません。
|
||
*
|
||
* このプラグインは2つの問題に対処します。
|
||
*
|
||
* 1.より多くのドロップを指定できます
|
||
* 2.パーセンテージを使用して確率を指定できます
|
||
*
|
||
* これにより、敵を設計する際の柔軟性が高まります。
|
||
* このプラグインを試してみてください！
|
||
*
|
||
* == 使用法 ==
|
||
*
|
||
* -- ItemCodeについて --
|
||
*
|
||
* 始める前に、'ItemCode'と呼ぶ概念を理解する必要があります。
|
||
* ItemCodeは、必要なアイテムの種類とアイテムのIDを簡潔に指定する方法です。
|
||
*
|
||
* ItemCodeを理解している場合、この説明を読まずに済みます。
|
||
*
|
||
* ItemCodeは次のようになります。
|
||
*
|
||
* a11
|
||
* w23
|
||
* i42
|
||
*
|
||
* 最初の文字はアイテムの種類を表します。
|
||
*
|
||
* a - 防具
|
||
* w - 武器
|
||
* i - アイテム
|
||
*
|
||
* 後の数字はデータベースIDです。書き方は下記になります。
|
||
*
|
||
* w23
|
||
*
|
||
* これは、敵が武器23を落とすことを意味します。
|
||
*
|
||
* -- 追加のドロップの管理 --
|
||
*
|
||
* 敵のドロップを作成するには、次のようなメモタグを敵のメモ欄へ記述します。
|
||
*
|
||
* <enemy drop>
|
||
* item_code: "ID",
|
||
* amount: number,
|
||
* chance: "FORMULA"
|
||
* </enemy drop>
|
||
*
|
||
* これらのコンマに注意してください。
|
||
* 追加のオプションがある場合、カンマを含める必要があります。
|
||
*
|
||
* 'item_code'は上記で説明したコードです。
|
||
* ドロップされるアイテムを示します。
|
||
*
|
||
* 'chance'は、パーセンテージとして数値に評価される式です。
|
||
* 数字を書くことができます。
|
||
*
|
||
* chance: "25"
|
||
*
|
||
* これで、25％の確率でドロップします。
|
||
*
|
||
* 別の方法として、JavaScriptコードを使用できます。
|
||
* 条件は3つの数式変数を提供します。
|
||
*
|
||
* enemy - この敵
|
||
* v - ゲーム変数
|
||
* s - ゲームスイッチ
|
||
*
|
||
* 例えば、このプラグインは、
|
||
* ゲーム変数へのアクセスを提供する'v'という特別な数式変数を提供します。
|
||
*
|
||
* chance: "v.value(3) * 10"
|
||
*
|
||
* 変数3の10倍の値が得られます。
|
||
* 式変数's'を使用して、スイッチにアクセスすることもできます。
|
||
* 例えば、
|
||
*
|
||
* chance: "s.value(2) === false ? 0 : 100"
|
||
*
|
||
* スイッチ2がオフの場合、0%になりますが、
|
||
* スイッチ2がオンの場合、100%になります。
|
||
*
|
||
* デフォルトでは、チャンスを指定しない場合、
|
||
* 100%でドロップするものと想定されます。
|
||
* 例えば、
|
||
*
|
||
* <enemy drop>
|
||
* item_code: "i1"
|
||
* </enemy drop>
|
||
*
|
||
* アイテム1を100％の確率でドロップします。
|
||
*
|
||
* 'amount'オプションは、そのアイテムをドロップする量を指定します。
|
||
* 例えば、
|
||
*
|
||
* <enemy drop>
|
||
* item_code: "w3",
|
||
* amount: 2
|
||
* </enemy drop>
|
||
*
|
||
* この場合、武器3を2つドロップします。
|
||
* 量を指定しない場合、1つを獲得します。

|
||
@plugindesc Allows you to add more drops to an enemy and use percentage
|
||
probabilities for drop chance.
|
||
@help
|
||
== Description ==
|
||
|
||
RPG Maker MV allows you to create up to three item drops for an enemy.
|
||
When the battle is over, the player may receive up to any of these
|
||
3 items.
|
||
|
||
When you specify drops, you use something called a "denominator"
|
||
probability, which is basically you specifying the chances of the item
|
||
dropping as a fraction of 1.
|
||
|
||
For example, if an item had a 1 /2 chance to drop, then it has a 50%
|
||
chance to drop. If an item had a 1 / 3 chance to drop, then it has a
|
||
33.33% chance to drop.
|
||
|
||
Unfortunately, with this system, you could never have any
|
||
probabilities in between.
|
||
|
||
This plugin addresses two issues:
|
||
|
||
1. You can specify more drops
|
||
2. You can specify probability using percentages
|
||
|
||
This should give you more flexibility when designing your enemies.
|
||
Give this plugin a try!

||
|
||
== Usage ==
|
||
|
||
-- Understanding Item Codes --
|
||
|
||
Before we begin, you must first understand a concept that I call
|
||
"Item Codes". The item code is a way for you to quickly specify
|
||
what kind of item you want, and the ID of the item.
|
||
|
||
If you already understand item codes you can just skip this part.
|
||
|
||
This is how an ItemCode looks like:
|
||
|
||
a11
|
||
w23
|
||
i42
|
||
|
||
The first letter represents the item kind.
|
||
|
||
a - armor
|
||
w - weapon
|
||
i - item
|
||
|
||
The number after is the database ID. So if you write
|
||
|
||
w23
|
||
|
||
That means the enemy will drop weapon 23.
|
||
|
||
-- Managing Additional Drops --
|
||
|
||
To create enemy drops, you would use a note-tag that looks like this:
|
||
|
||
<enemy drop>
|
||
item_code: "ID",
|
||
amount: number,
|
||
chance: "FORMULA"
|
||
</enemy drop>
|
||
|
||
Take note of those commas: if you have additional options, you must
|
||
include a comma.
|
||
|
||
`item_code` is the code that was described above. This indicates which
|
||
item will be dropped.
|
||
|
||
`chance` is a formula that evaluates to a number as a percentage.
|
||
So for example, you could write numbers
|
||
|
||
chance: "25"
|
||
|
||
Which means 25% chance to drop.
|
||
|
||
Alternatively, you can use javascript code if you know how to write them.
|
||
The condition offers 3 formula variables
|
||
|
||
enemy - this enemy
|
||
v - game variables
|
||
s - game switches
|
||
|
||
|
||
For example, this plugin gives you a special formula variable called `v`
|
||
which gives you access to the game variables.
|
||
|
||
chance: "v.value(3) * 10"
|
||
|
||
Which gives you 10 times the value of variable 3.
|
||
You can also use the formula variable "s" to give you access to switches.
|
||
So for example,
|
||
|
||
chance: "s.value(2) === false ? 0 : 100"
|
||
|
||
Which means if switch 2 is OFF, it drops with 0%, but if the switch is
|
||
ON, then you get it 100%.
|
||
|
||
By default, if you don't specify a chance, then it is assumed to drop
|
||
at 100%.
|
||
|
||
For example, if you write
|
||
|
||
<enemy drop>
|
||
item_code: "i1"
|
||
</enemy drop>
|
||
|
||
Then it will drop item 1 100% of the time.
|
||
|
||
The `amount` option tells the game how much of that item should drop.
|
||
For example, if you write
|
||
|
||
<enemy drop>
|
||
item_code: "w3",
|
||
amount: 2
|
||
</enemy drop>
|
||
|
||
Then it will drop two of weapon 3. If you don't specify an amount, then
|
||
the game assumes you will only get 1.
