    I created a class that extends net.minecraft.server.EntityPlayer,
    when I spawn a zombie near a player it gets set to the fake player, but when I hit the fake player entity the server crashes and gives me this error:

    Code:

    The FakePlayer class

    Code:
    package me.Mew32.TestPlugin;
 
import org.bukkit.Location;
import org.bukkit.entity.Player;
import org.bukkit.event.player.PlayerMoveEvent;
 
import net.minecraft.server.ItemInWorldManager;
import net.minecraft.server.MinecraftServer;
import net.minecraft.server.World;
 
public class FakePlayer extends net.minecraft.server.EntityPlayer{
 
    public FakePlayer(MinecraftServer craftServer, World world, String s) {
        super(craftServer, world, s, new ItemInWorldManager(world));
    }
   
    @Override
    public void h_(){
        Player NPCPlayer = (Player) this.getBukkitEntity();
       
 
        Location from = new Location(NPCPlayer.getWorld(), this.lastX, this.lastY, this.lastZ, this.lastYaw, this.lastPitch);
        Location to = new Location(NPCPlayer.getWorld(), this.locX, this.locY, this.locZ, this.yaw, this.pitch);
 
        PlayerMoveEvent event = new PlayerMoveEvent(NPCPlayer, from, to);
 
        this.world.getServer().getPluginManager().callEvent(event);
 
        if (event.isCancelled() && NPCPlayer.isDead() == false){
            return;
        }
 
        super.h_();
    }
 
}
    [/SPOILER

    What do I have to add to my FakePlayer class to prevent an error happening?

    Your error:
    java.lang.NoSuchMethodException: me.Mew32.TestPlugin.FakePlayer.<init>(net.minecraft.server.World)

    In other words, you forgot the constructor that takes just a World param. :)

    Update the version of Bukkit you are compiling against. Then the compiler will give you an error for this. The problem is with your call to super.
