= Modify map TMX file=
The maps files are just XML files with special tags, open your maps and make sure that you set x,y position of your map on the world.
Semos village is right now (500000,500000) so use something near yours to set correctly the map position.

In the case of non-interior zones, the level and x/y coordinate should also be included in the <zone> element (setting them in the tmx file has been deprecated). For interior zones, the level xml attribute should '''not''' be set (for now).
In the case of non-interior zones, the level and x/y coordinate should also be included in the <zone> element (setting them in the tmx file has been deprecated). For interior zones, the level xml attribute should '''not''' be set (for now). The coordinate starts at the top-left corner, and should align against (but never overlap) other zones in the same level.

If the new zone is outside, or otherwise should follow the normal daylight cycle, add a coloring method definition to it, like this:

</attributes>
</zone>

About other possible coloring methods for maps, see [[LightsAndColor | Lights and Color]].


Most zones can be configured just using this xml file. However, there are currently some things, such as NPC's that need special handling. If you need to do custom zone configuration, create one or more new java source file(s) at '''src/games/stendhal/server/maps/<area>/<base-location>/<entity>.java'''. The '''<area>/<base-location>''' path would essentially be the same as your '''.tmx''' file uses. In case where locations have been split due to size (like _nw, _ne, _s, _n, etc), only the base location name is used.

The House door portal is a special type of portal that automatically creates all the portals and areas needed to add a house to that zone with its entrance on point where the portal is. In tiled/tileset/logic/portals.png it's the one with the door on it. Add it to the 'city' type map where you want the house entrance. Please see [[HowToUseTiledToCreateStendhalMaps2#Objects_revisited|the tiled tutorial]].


Finally the stairs portals also automate the creation of stairs between two areas. It is very important that the portals ( both ends ) are exactly on the same position but on different levels. Position means absolute position. Also, due to current implementation, be careful '''not''' to place omni-directional stair portals at the same exact location between adjacent levels if they're not meant to be linked, as they might inadvertantly be linked. Directional stairs are safer and only link with the level they go toward.

=== Condition and Action Portals ===
== Adding NPCs ==
Portals are being refactored to allow combinations of conditions and actions in a very similar way to NPCs. In fact, you can use the same conditions and actions.
Usually we add NPCs (non-player characters) to make world more alive and to use them in Quests. It is because of that reason, that is so important that you add NPC on the zone they are.
The full list is found in http://arianne.cvs.sourceforge.net/arianne/stendhal/src/games/stendhal/server/entity/npc/action and http://arianne.cvs.sourceforge.net/arianne/stendhal/src/games/stendhal/server/entity/npc/condition


A portal which you can put a Condition and / or action to is called a ConditionAndActionPortal. You don't have to set both a condition and an action.
=== The old way ===


Implement them like this:
This is how NPCs used to be added to the world. The downside of this is that you need a lot of Java code. If you're adding new NPCs, consider using the new way of doing it, as described in the next section.


<source lang="xml">
''SpeakerNPC npc = new SpeakerNPC() { ... }'' creates a new NPC. ''NPCList.get().add(npc)'' adds it to a global list so next time you need to get the NPC for participating in a quest, or if you want to teleportto it, you can call it by its ''name'' using ''NPCList.get().get(name)''.
<portal x="64" y="117" ref="entrance">
<pre>
<destination zone="-1_semos_chasm_n" ref="exit" />
SpeakerNPC npc = new SpeakerNPC("name") {
<implementation class-name="games.stendhal.server.entity.mapstuff.portal.ConditionAndActionPortal">
/...
<parameter name="condition">new PlayerHasItemWithHimCondition("special magical thingy", 10)</parameter>
});
<parameter name="action">new DropItemAction("special magical thingy", 10)</parameter>
</pre>
<parameter name="rejected">You need 10 of the special magical thingies.</parameter>
</implementation>
</portal>
</source>


You can use NotConditions:
Notice that in this case, the name is especified first in ''NPC npc=npcs.add("name",...''


<source lang="xml">
<portal x="65" y="13" ref="entrance">
<destination zone="-1_semos_chasm_w" ref="exit" />
<implementation class-name="games.stendhal.server.entity.mapstuff.portal.ConditionAndActionPortal">
<parameter name="condition">new NotCondition(new PlayerHasPetOrSheepCondition())</parameter>
<parameter name="rejected">To get into the evil chasm you must bring a sacrificial animal</parameter>
</implementation>
</portal>
</source>


You can do more than one action by using MultipleActions and list the actions for it, and combine Conditions with an AndCondition, listing the conditions for it.
In other words, ''new SpeakerNPC()'' creates just a new NPC of the class SpeakerNPC but with ''npcs.add("name",new SpeakerNPC()...)'' you are in fact extending SpeakerNPC to add new functionality.
The syntax is slightly different than with NPCs, please note these extra [ ] surrounding the list. This is due to a bug in groovy.


<source lang="xml">
<portal x="37" y="16" ref="example1">
<destination zone="int_semos_zone" ref="choice_floor_1" />
<implementation class-name="games.stendhal.server.entity.mapstuff.portal.ConditionAndActionPortal">
<parameter name="condition">new AndCondition([new NotCondition(new PlayerHasItemWithHimCondition("claymore")) , new LevelLessThanCondition(100)])</parameter>
<parameter name="action">new MultipleActions([new IncreaseXPAction(100), new EquipItemAction("claymore")])</parameter>
</implementation>
</portal>
</source>


The destination settings and references are all as normal. You can still set other attributes like a reject message and hidden from minimap, as in some of the examples above.
In this case, let's suppose you plan on using our NPC later in a quest, so use something like:

<pre>
SpeakerNPC npc = new SpeakerNPC("Ilisa") {
protected void createPath() {
List<Path.Node> nodes=new LinkedList<Path.Node>();
nodes.add(new Path.Node(9,5));
nodes.add(new Path.Node(14,5));
setPath(nodes,true);
}

protected void createDialog() {
// Lets the NPC reply with "Hallo" when a player greets her
addGreeting();
// Lets the NPC reply when a player says "job"
addJob("I have healing abilities and I heal wounded players. I also sell potions and antidotes.");
// Lets the NPC reply when a player asks for help
addHelp("Ask me to #heal you and I will help you or ask me #offer and I will show my shop's stuff.");
// Makes the NPC sell potions and antidote
addSeller(new SellerBehaviour(shops.get("healing")));
// Lets the NPC heal players for free
addHealer(0);
addGoodbye();
}
});
NPCList.get().add(npc);
zone.assignRPObjectID(npc);
// This determines how the NPC will look like.
npc.put("class", "welcomernpc");
npc.set(9, 5);
npc.initHP(100);
zone.add(npc);
</pre>

Because we used '''NPCList.get().add(npc)''', the NPC is added to a list of NPC from where you can later obtain it for adding more dialogues for quests. Make sure the name you give to your NPC is unique.

Just after that it is a good idea to create a path that the NPC will follow on that area.
And then create a dialog. Dialogs and such are explained in Quest sections.

Now simply assign an id to the NPC, set its outfit either by:
* setting its class to a PNG image that exists at ''data/sprites/npc''
* setting its outfit with setOutfit method.
See [[StendhalOpenTasks#Player's outfits| How to know player's outfits specifications]]

Finally set its initial position and its HP. Don't worry for your NPC. It can't be attacked nor killed.

Once that is done add the NPC to zone using ''zone.add()'' method.

=== The new way ===

This is the new way of adding NPCs. It requires less Java coding skills; Java code is only required for the dialog and for special behaviour, everything else is defined in XML.

First, you need to create a Java file for the dialog. You should put it in a subpackage of <code>games.stendhal.server.maps</code>; the package describes where NPC is located.

For example, here is the Java code for a simple NPC on Athor island:

package games.stendhal.server.maps.athor.holiday_area;
import games.stendhal.server.entity.npc.SpeakerNPC;
import games.stendhal.server.entity.npc.SpeakerNPCFactory;
public class SwimmerNPC extends SpeakerNPCFactory {
@Override
protected void createDialog(SpeakerNPC npc) {
npc.addGreeting("Don't disturb me, I'm trying to establish a record!");
npc.addQuest("I don't have a task for you, I'm too busy.");
npc.addJob("I am a swimmer!");
npc.addHelp("Try the diving board! It's fun!");
npc.addGoodbye("Bye!");
};
}

This will make the NPC react to typical words that players might say to him, e.g. "hi", "help", and "bye". This Java class is stored in the file <code>/src/games/stendhal/server/maps/athor/holiday_area/SwimmerNPC.java</code>. Of course this is just a simple example, and more sophisticated dialogs and behaviours are possible with more complex Java code.

Next, we need place the NPC and set the name and some other attributes. The NPC in the example lives on Athor island, so the information is stored in <code>data/conf/zones/athor.xml</code>. The map he's on is called 0_athor_island, so the information is inside the <code><zone name="0_athor_island"...> ... </zone></code> tag:

<entity x="67" y="63">
<implementation class-name="games.stendhal.server.maps.athor.holiday_area.SwimmerNPC">
<parameter name="name">Enrique</parameter>
<parameter name="class">swimmer3npc</parameter>
<parameter name="node0">67,68</parameter>
<parameter name="node1">67,63</parameter>
</implementation>
</entity>

* The first line says that the NPC should initially be placed at the point (67, 63).
* The second line tells the server where we stored our Java file with the dialog.
* The third line says that our NPC should be called Enrique.
* The fourth line defines how the NPC should look like. In this case, the graphics from the file <code>data/sprites/npc/swimmer3npc.png</code> will be used.
* The fifth and sixth lines define the path along which Enrique should walk/swim. He will first visit the point (67, 68), then return to his start position (67, 63), and continue like this infinitely. You can of course create NPCs with more than 2 nodes, but:
** keep in mind that counting starts with 0
** make sure that you don't forget a node number, e.g. if you have node6, you must also have node5, node4 etc.

If you don't want your NPC to walk around, just leave out the node parameters. Instead, you should add a parameter that defines in which direction the NPC should look on server startup (left, right, up, down), e.g.:

<parameter name="direction">down</parameter>

Other parameters you can use:

<parameter name="hp">50</parameter>

This will make the NPC look wounded (the health bar will be at the middle). Note that, as NPCs cannot be killed, this is only for decoration. If you leave this parameter out, the hitpoints will be set to 100, which means full health.

<parameter name="level">10</parameter>

This sets the NPC's level of experience. Again, this is only for decoration, as NPCs don't fight or die.

Of course you have already read:

Ok, and I assume that you can write or at least read xml.


Modify world.tmx

Now make sure if your map is new that world.tmx shows it by adding a new tileset with your map image. This step is just for your mental wellness. Stendhal doesn't use world.tmx.

Create a map file

If you are adding a zone for a new major area, create the file data/conf/zones/<area>.xml with the following: 

<?xml version="1.0" encoding="UTF-8"?>
<zones>
 <!--
   ** Load zones. Written from left to right and from top to bottom.
   ** Please respect it!
   -->

</zones>

Then edit the file data/conf/zones.xml and add a relevant entry (in alphabetical order for normal areas): 

 <group uri="zones/<area>.xml"/>

To enable a zone in the server, edit the file data/conf/zones/<area>.xml and add an entry (in the appropriate level/top-down/left-right order), giving it the zone name and map tmx file to use:

<source lang="xml"> 

<zone name="int_myarea_mylocation" file="interiors/myarea/mylocation.tmx"/>
<zone name="0_myarea_mylocation" level="0" x="100000" y="200000" file="Level 0/myarea/mylocation.tmx"/>

</source>

In the case of non-interior zones, the level and x/y coordinate should also be included in the <zone> element (setting them in the tmx file has been deprecated). For interior zones, the level xml attribute should not be set (for now). The coordinate starts at the top-left corner, and should align against (but never overlap) other zones in the same level.

If the new zone is outside, or otherwise should follow the normal daylight cycle, add a coloring method definition to it, like this:

<source lang="xml"> 

<zone name="0_myarea_mylocation" level="0" x="100000" y="200000" file="Level 0/myarea/mylocation.tmx">
 <attributes>
  <parameter name="color_method">time</parameter>
 </attributes>
</zone>

</source>

About other possible coloring methods for maps, see Lights and Color.

Most zones can be configured just using this xml file. However, there are currently some things, such as NPC's that need special handling. If you need to do custom zone configuration, create one or more new java source file(s) at src/games/stendhal/server/maps/<area>/<base-location>/<entity>.java. The <area>/<base-location> path would essentially be the same as your .tmx file uses. In case where locations have been split due to size (like _nw, _ne, _s, _n, etc), only the base location name is used.

Ideally this would be one file per independant entity created (so they can be enabled/disabled separately).

Some (ficticious) examples for the new convention of tmx path to java filename are: 

interiors/orril/old_cabin.tmx -> .../maps/orril/old_cabin/HermitNPC.java
Level 0/ados/rock.tmx -> .../maps/ados/rock/NomadNPC.java
Level -1/ados/caves_e.tmx -> .../maps/ados/caves/CaveinTrigger.java
Level 0/nalwor/river_se.tmx -> .../maps/nalwor/river/FishermanNPC.java
Level 0/nalwor/river_se.tmx -> .../maps/nalwor/river/AdventurerNPC.java
Level 0/nalwor/river_sw.tmx -> .../maps/nalwor/river/CamperNPC.java
Level 0/semos/forest_n.tmx -> .../maps/semos/forest/LumberjackNPC.java

Open the file and make sure that it looks like this:

<source lang="java"> package games.stendhal.server.maps.myarea.mylocation;

import java.util.Map; import games.stendhal.server.StendhalRPZone; import games.stendhal.server.config.ZoneConfigurator;

public class MyEntity implements ZoneConfigurator { 

   /**
    * Configure a zone.
    *
    * @param       zone            The zone to be configured.
    * @param       attributes      Configuration attributes.
    */
   public void configureZone(StendhalRPZone zone, Map<String, String> attributes) {
       // Add/configure entity to "zone", using optional configuration "attributes"
   }

} </source>

For each custom configuration code class, add appropriate "<configurator>" entries in your "<zone>" element, using the fully qualified package/class name of your java classes:

<source lang="xml"> 

<zone name="int_myarea_mylocation" file="interiors/myarea/mylocation.tmx">
 <configurator class-name="games.stendhal.server.maps.myarea.mylocation.MyEntity"/>
</zone>

</source>

Now once it is added, test the result by starting server.

Populating zones

Now open again the MyEntity.java file and let's start adding code to configureZone(), or a method called by it. Most usual things we are going to add to a zone are NPC, and special items.

Adding Items

See How to add items to Stendhal and How to know graphics specifications

Adding Portals

A portal is a door to another place. It can be used to go up and down stairs, or to teleport player to other places or simply to enter a building. Whenever you encounter something that engine challenges you about how to do ( for example cross under a brigde or pass under a castle door ) you can solve it using portals.

There are several types of portals:

  • Portal added using xml
  • One way portal added using xml
  • Stairs portals added using tiled
  • House Door portals added using tiled

A portal is just the generic portal. It works for almost everything you can imagine.

Portals are created by adding a entries to your zone in zones.xml. For example creating a portal to an internal building entrance which is at 1 12 inside the building (and the outer entrance to go in is at 10 15) might look like:

<source lang="xml"> 

<zone name="int_myarea_mylocation" file="interiors/myarea/mylocation.tmx">
   <portal x="1" y="12" ref="entrance">
    <destination zone="0_myarea_city" ref="mylocation_entrance"/>
   </portal>
</zone>

<zone name="0_myarea_city" Level="0" x="500000" y="500000" file="Level 0/myarea/city.tmx">
   <portal x="10" y="15" ref="mylocation_entrance">
    <destination zone="int_myarea_location" ref="entrance"/>
   </portal>
</zone>

</source>

The ref attribute of a portal should be a name unique to the zone it is in (and meaningful). This value has a corresponding reference via the <destination> ref name. You are responsible for correctly assigning the ref names of each portal.

A one way portal is a portal that only exists as endpoint, so none can use the portal to move back to the origin. For one way portals, there is no <destination> sub-element, as they don't go anywhere. Also, you need to provide a non-default implementation:

<source lang="xml"> 

 <portal x="11" y="44" ref="my_exit">
  <implementation class-name="games.stendhal.server.entity.mapstuff.portal.OneWayPortalDestination"/>
 </portal>

</source>

The House door portal is a special type of portal that automatically creates all the portals and areas needed to add a house to that zone with its entrance on point where the portal is. In tiled/tileset/logic/portals.png it's the one with the door on it. Add it to the 'city' type map where you want the house entrance. Please see the tiled tutorial.

Finally the stairs portals also automate the creation of stairs between two areas. It is very important that the portals ( both ends ) are exactly on the same position but on different levels. Position means absolute position. Also, due to current implementation, be careful not to place omni-directional stair portals at the same exact location between adjacent levels if they're not meant to be linked, as they might inadvertantly be linked. Directional stairs are safer and only link with the level they go toward. The the tiled tutorial covers this in more detail.

Condition and Action Portals

Portals are being refactored to allow combinations of conditions and actions in a very similar way to NPCs. In fact, you can use the same conditions and actions. The full list is found in http://arianne.cvs.sourceforge.net/arianne/stendhal/src/games/stendhal/server/entity/npc/action and http://arianne.cvs.sourceforge.net/arianne/stendhal/src/games/stendhal/server/entity/npc/condition

A portal which you can put a Condition and / or action to is called a ConditionAndActionPortal. You don't have to set both a condition and an action.

Implement them like this:

<source lang="xml"> 

<portal x="64" y="117" ref="entrance">
 <destination zone="-1_semos_chasm_n" ref="exit" />
 <implementation class-name="games.stendhal.server.entity.mapstuff.portal.ConditionAndActionPortal">
  <parameter name="condition">new PlayerHasItemWithHimCondition("special magical thingy", 10)</parameter>
  <parameter name="action">new DropItemAction("special magical thingy", 10)</parameter>
  <parameter name="rejected">You need 10 of the special magical thingies.</parameter>
 </implementation>
</portal>

</source>

You can use NotConditions:

<source lang="xml"> 

<portal x="65" y="13" ref="entrance">
 <destination zone="-1_semos_chasm_w" ref="exit" />
 <implementation class-name="games.stendhal.server.entity.mapstuff.portal.ConditionAndActionPortal">
  <parameter name="condition">new NotCondition(new PlayerHasPetOrSheepCondition())</parameter>
  <parameter name="rejected">To get into the evil chasm you must bring a sacrificial animal</parameter>
 </implementation>
</portal>

</source>

You can do more than one action by using MultipleActions and list the actions for it, and combine Conditions with an AndCondition, listing the conditions for it. The syntax is slightly different than with NPCs, please note these extra [ ] surrounding the list. This is due to a bug in groovy.

<source lang="xml"> 

  <portal x="37" y="16" ref="example1">
    <destination zone="int_semos_zone" ref="choice_floor_1" />
    <implementation class-name="games.stendhal.server.entity.mapstuff.portal.ConditionAndActionPortal">
      <parameter name="condition">new AndCondition([new NotCondition(new PlayerHasItemWithHimCondition("claymore")) , new LevelLessThanCondition(100)])</parameter>
      <parameter name="action">new MultipleActions([new IncreaseXPAction(100), new EquipItemAction("claymore")])</parameter>
    </implementation>
  </portal>

</source>

The destination settings and references are all as normal. You can still set other attributes like a reject message and hidden from minimap, as in some of the examples above.
