Line 3: {{Stendhal NPCs}} 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~~. This is how NPCs are added to the world. Line 10: More complicated dialog for NPCs, such as you'd find in a quest, is covered in [[Stendhal Quest Coding]]. But the basics for any NPC used in a quest should still be written as below. == Before you start == This page describes how to code an NPC. You don't need to know a lot about Java. You should, however, already have [[Configure a development environment (IDE)\|setup an IDE]] and be able to compile and start a local Stendhal server. == Define NPC with Java == Line 56 ⟶ 60: / public void configureZone(final StendhalRPZone zone, final Map<String, String> attributes) { buildNPC(zone~~, attributes~~); } Line 64 ⟶ 68: <source lang="java"> private void buildNPC(final StendhalRPZone zone~~, final Map<String, String> attributes~~) { final SpeakerNPC npc = new SpeakerNPC("Mr Healer") { protected void createPath() { List<Node> nodes=new LinkedList<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 him. But we could have set ~~one~~a custom greeting inside the () 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); // respond about a special trigger word addReply("potions","Please ask for my #offer."):; // use standard goodbye, but you can also set one inside the () addGoodbye(); } }); // This determines how the NPC will look like. welcomernpc.png is a picture in data/sprites/npc/▼ ~~zone.assignRPObjectID(npc);~~ npc.setEntityClass("welcomernpc");▼ ▲ // This determines how the NPC will look like. welcomernpc.png is a picture in data/sprites/npc/ // set a description for when a player does 'Look' ▲ npc.setEntityClass("welcomernpc"); npc.setDescription("You see Mr Healer, he looks a a bit busy at the moment but perhaps he can help you anyway."); // Set the initial position to be the first node on the Path you defined above. ~~npc.setPosition(9, 5);~~ npc.~~initHP~~setPosition(~~100~~9, 5); npc.initHP(100); zone.add(npc); } } </source> Line 127 ⟶ 134: We set its outfit either by: setting its class to a [[StendhalRefactoringGraphics#NPCs\|PNG image]] that exists at ''data/sprites/npc'', e.g. <code>npc.setEntityClass("welcomernpc");</code> * setting its outfit with setOutfit method e.g. <code>npc.setOutfit(new Outfit(0, 05, 01, 06, 01));</code> - see [http://stendhalgame.org/hudson/job/stendhal_HEAD/javadoc/games/stendhal/server/entity/Outfit.html Outfit javadoc] ~~See [[StendhalOpenTasks#Player's outfits\| How to know player's outfits specifications]]~~ It is nice to set a description for when the player does ''Look''. If you don't set one, it will just say: ''You see [NPC Name].'' Finally set its initial position and its HP. Don't worry for your NPC. It can't be attacked nor killed.
