monsters.xml file configuration

Data from the monsters.xml file are used to set up configuration values about every computered related beings the players will encounter during the online experience.

The monsters.xml file has to be located in the data directory.

Each configuration option in this xml file, is defined using a <monster> tag within the <monster**s**> main node, which itself has got an <attributes> child node, and some others. Here is an example:

 <?xml version="1.0"?>
 <monsters>
    <monster id="0" name="Maggot" targetCursor="small">
      <attributes
        hp="20"
        size="4"
        speed="2.0"
        evade="5"
        physical-defence="5"
        magical-defence="0"
        mutation="50"
      />
      <attack id="1"
        priority="1"
        type="physical"
        warmuptime="10"
        cooldowntime="10"
        reusetime="10"
        basedamage="10"
        deltadamage="1"
        chancetohit="1000"
        element="neutral"
        range="32"
        animation="attack"
      />

      <exp>10</exp>
    </monster>
 </monsters>

Note: This file can be used by both the client and the server if the necessary data is provided. That’s why we provide options for both applications here for simplification and easier documentation purpose. But when you should be careful to provide only the client data when dealing with client configuration, or the players will more information about the monsters than they should actually have.

General (Client and server) nodes description

<monsters> node description

The &lt;monsters&gt; node is the monsters.xml file main node and permits to determine monsters definition start and ending. This node has only one parameter for now, offset, which is added to all the monster IDs. It defaults to 1002 for the TmwAthena protocol, for backwards compatibility with older clients, which did it automatically in the netcode.

This node is required by both the client and the server.

 <?xml version="1.0"?>
 <monsters>
 ...
 </monsters>

<monster> node description

The &lt;monster&gt; node is used to define the different values used to bring a specific monster up to life within the game. Each monster’s definition is then defined within its start and ending tags.

This node is required by both the client and the server.

 <?xml version="1.0"?>
 <monsters>
   <monster id="1" name="Monster Name">
   ...
   </monster>
 ...
 </monsters>
Parameter name Type Mandatory Default value Description
id integer Yes   It is the id of the monster. This parameter has to be unique for each monster.
The system will use the monster id to refer on it in many ways.
name string No “unnamed” Tells the monster name. Used to ease configuration on server and with the client
but displayed to players on the client side.
targetCursor string
defined value
No “normal” Used by the client only. Tells which circle cursor size should be use when displaying the target cursor around the monster sprite while in game. It mainly depends on the sprite’s pixel size.
Acceptable values are:
