    Hello, I have developed a code and I am trying to spawn a mob in. I got the code and pathfinders ready but I haven't figured out how to spawn it in. Help would be nice :D or a guide.

    Code:java
    1.  
    2. package com.mrgreen33gamer.test;
    3.  
    4. import java.lang.reflect.Field;
    5.  
    6. import org.bukkit.craftbukkit.v1_7_R3.util.UnsafeList;
    7.  
    8. import net.minecraft.server.v1_7_R3.EntityHuman;
    9. import net.minecraft.server.v1_7_R3.EntityVillager;
    10. import net.minecraft.server.v1_7_R3.GenericAttributes;
    11. import net.minecraft.server.v1_7_R3.PathfinderGoalLookAtPlayer;
    12. import net.minecraft.server.v1_7_R3.PathfinderGoalSelector;
    13. import net.minecraft.server.v1_7_R3.World;
    14.  
    15. public class CustomVillager extends EntityVillager {
    16.  
    17. public CustomVillager(World world, int i) {
    18. super(world);
    19.  
    20. this.setProfession(i);
    21. try {
    22. Field bField = PathfinderGoalSelector.class.getDeclaredField("b");
    23. bField.setAccessible(true);
    24. Field cField = PathfinderGoalSelector.class.getDeclaredField("c");
    25. cField.setAccessible(true);
    26.  
    27. bField.set(goalSelector, new UnsafeList<PathfinderGoalSelector>());
    28. bField.set(targetSelector, new UnsafeList<PathfinderGoalSelector>());
    29. cField.set(goalSelector, new UnsafeList<PathfinderGoalSelector>());
    30. cField.set(targetSelector, new UnsafeList<PathfinderGoalSelector>());
    31.  
    32. } catch (Exception e) {
    33. e.printStackTrace();
    34. }
    35. setUp();
    36. }
    37.  
    38. public void setUp(){
    39. this.goalSelector.a(10, new PathfinderGoalLookAtPlayer(this, EntityHuman.class, 8.0F));
    40. }
    41.  
    42. @Override
    43. protected void aC(){
    44. super.aC();
    45. this.getAttributeInstance(GenericAttributes.d).setValue(0.0D);
    46. this.getAttributeInstance(GenericAttributes.a).setValue(Double.MAX_VALUE);
    47. this.getAttributeInstance(GenericAttributes.c).setValue(Double.MAX_VALUE);
    48. }
    49. }
    50.  



    Use this code if it's useful for you :D!

    Yes but I cannot spawn the mob in at my location, example:
    Code:
    Villager villager = (Villager)player.getWorld().spawnCreature(player.getLocation(), CreatureType.VILLAGER);
    But using the custom class I made.
    Thanks for the post :D!
