    bluegru - yes, there's a max range configurable both in the settings and in the pathfinder config.

    thx,
    and is it possible to make the NPC attackable?
    So that the player can kill the NPC

    I'm having a problem with the nametags again... The runnable throws a lot of errors, so I decided to make it again. How can I set the nametag for a NPC everytime the server loads? Also, how would I make it not disappear after a player leaves the server?
    I don't know how to use traits, and the tutorial on the wiki is very confusing. If someone could help me, I would be very happy.

    #Edit: Nevermind, fixed! :D

    guitargun - yes, simply use npc.data().set(NPC.DEFAULT_PROTECTED_METADATA, false);

    My Citizens plugin doesn't work!
    I tried to re-install it already, didn't work.

    http://pastebin.com/7aU7RBST

    It says I have to downgrade or something, yesterday evening it did work.
    Today I joined my MC-Server, and it didn't work.
    I didn't upgrade anything :O

    Any solutions?

    I made the npc walk in a random direction in a set radius
    Code:java
    1. NPCRegistry registry = CitizensAPI.getNPCRegistry();
    2. final NPC npc = registry.getNPC(npclist.get(npcname).getEntity());
    3. final Location startFrom = npcloc.get(npcname);
    4. final Random rndGen = new Random();
    5. final int[] values = new int[3];
    6.  
    7.  
    8. int id = Bukkit.getScheduler().scheduleSyncRepeatingTask(Bukkit.getPluginManager().getPlugin("NPCWalker"), new Runnable(){
    9. public void run(){
    10. for(int i = 0; i < 3; i++) {
    11. values[I] = rndGen.nextInt(4) + 1;
    12.  
    13. }
    14. Location output = startFrom.clone();
    15. Random x = new Random();
    16. int y = x.nextInt(3) + 1;
    17. switch(y){
    18. case 1:
    19. output.add(values[0], 0, values[2]);
    20. break;
    21. case 2:
    22. output.subtract(values[0], 0, values[2]);
    23. break;
    24. case 3:
    25. int k = values[0] - values[0]*2;
    26. output.add(k, 0, values[2]);
    27. break;
    28. case 4:
    29. int l = values[2] - values[2]*2;
    30. output.add(values[0], 0, l);
    31. break;
    32. }
    33. npc.getNavigator().setTarget(output);
    34. npcloc.put(npc, output);
    35. }
    36. }, 0L , 200L);
    37. movementsched.put(npc, id);

    I got it working now.

    I got another question, is there a possibility that the NPC Nametags can be hided?
     
  11. Offline

    fullwall

    Serold - /npc name or using the API entity.setCustomNameVisible(false). Note that this does not work for Players.

    Serold

    That doesn't work for me..

    When I do /Npc Name
    it says, Nameplate visibility toggled

    fullwall

    Serold - if it's not a Player, then the nameplate will be hidden if you're looking away.

    Very cool API, but is it possible for a citizen to lay in a bed? That would be so awesome :)
     
  16. Offline

    fullwall

    tacticalsk8er - you need to let Citizens2 load before you start calling its methods.
    TVXtrem - yes, if you depend on Citizens2 you can call PlayerAnimation methods.

    TVXtrem

    fullwall Yes, but if you call the sleep animation method, the npc is bugging through the floor. :/
     
  18. Offline

    fullwall

    TVXtrem - you should move the NPC up one block and then try the animation.

    LegitJava - yep, that's correct. Player NPCs will just have steve skins.
    @elementalgoz11 - hm, that's strange. First of all, setProtected(false) should make them damageable without needing to listen for any events. Have you verified that the NPCs have their protected metadata set to false?
