编辑“︁Stendhal Quest Coding”︁（章节）

== Creating a quest skeleton ==

This tutorial is based on the quest "Beer For Hayunn". As this quest already exists, you may want to delete the java file locally in order to follow this tutorial.

Quest files are put into the package games.stendhal.server.maps.quests. (If you are new to Java: this refers to the folder stendhal/src/games/stendhal/server/maps/quests).

Please create a new file in that folder called BeerForHayunn.java. (Note: The upper / lower case spelling is important, even on Microsoft Windows):

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

import games.stendhal.server.entity.npc.*;
import games.stendhal.server.entity.npc.action.*;
import games.stendhal.server.entity.npc.condition.*;
import games.stendhal.server.entity.player.*;
import java.util.*;

public class BeerForHayunn extends AbstractQuest {

    public static final String QUEST_SLOT = "beer_hayunn";

    @Override
    public void addToWorld() {
        super.addToWorld();
    }

    @Override
    public String getSlotName() {
        return QUEST_SLOT;
    }

    @Override
    public String getName() {
        return "BeerForHayunn";
    }

    public List<String> getHistory(final Player player) {
        final List<String> res = new ArrayList<String>();
        return res;
    }
}
</source>

Don't worry, if you don't understand a word of this; just copy it. We will explain the important parts and extend this skeleton in the following sections.

In order for the Stendhal server to pick up this file, it has to be registered in the file StendhalQuestSystem.java in the package games.stendhal.server.core.rp by adding two lines at the appropriate places:

<source lang="java">
import games.stendhal.server.maps.quests.BeerForHayunn;

// [...]

loadQuest(new BeerForHayunn());
</source>

Of course in the case of this tutorial the two lines for BeerForHayunn are already there.
