    Whats the code you used?
     
  2. Code:
        @Override
        public void g(float sideMot, float forMot) {
            if (this.passenger != null && this.passenger instanceof EntityHuman) {
                this.lastYaw = this.yaw = this.passenger.yaw;
                this.pitch = this.passenger.pitch * 0.5F;
                this.setYawPitch(this.yaw, this.pitch);//Update the pitch and yaw
                this.aI = this.aG = this.yaw;
                sideMot = ((EntityLiving) this.passenger).aX * 0.5F;
                forMot = ((EntityLiving) this.passenger).aY;
                if (forMot <= 0.0F) {
                    forMot *= 0.25F;// Make backwards slower
                }
    
                Field jump = null;
                try {
                    jump = EntityLiving.class.getDeclaredField("aW");
                } catch (NoSuchFieldException e1) {
                    e1.printStackTrace();
                } catch (SecurityException e1) {
                    e1.printStackTrace();
                }
                jump.setAccessible(true);
                if (jump != null && this.onGround) {
                    try {
                        if (jump.getBoolean(this.passenger)) {
                            double jumpHeight = 0.5D;
                            this.motY = jumpHeight;
                        }
                    } catch (IllegalAccessException e) {
                        e.printStackTrace();
                    }
                }
               
                this.S = 1.0F;// The custom entity will now automatically climb up 1 high blocks
                this.aK = this.bH() * 0.1F;
                if (!this.world.isStatic) {
                    this.j(0.35F);//Here is the speed the entity will walk.
                    super.g(sideMot, forMot);
                }
    
                this.ay = this.az;//Some extra things
                double d0 = this.locX - this.lastX;
                double d1 = this.locZ - this.lastZ;
                float f4 = MathHelper.sqrt(d0 * d0 + d1 * d1) * 4.0F;
                if (f4 > 1.0F) {
                    f4 = 1.0F;
                }
    
                this.az += (f4 - this.az) * 0.4F;
                this.aA += this.az;
            } else {
                this.S = 0.5F;
                this.aK = 0.02F;
                super.g(sideMot, forMot);
            }
        }
    @TGRHavoc Was told this.S controls the blocks at which an animal will climb automatically. This is true for all animals but the horse apparently.

    I'm completely fine with you continuing the original tutorial. My only problem was that you didn't noticeably attempt to write/update it yourself (other than a few obfuscation changes) in creating a new thread.

    I haven't been frequenting these forums as often as I used to; by the time I was able to respond to that thread, it was already solved. Sorry I couldn't be of assistance in time ):

    Feel free to poke me on IRC if you require any more help :).

    Ok, I guess you are right, maybe @Funergy could link to your 1.7.10- tut.

    Funergy

    @DSH105 Why did you think that I just needed to change some obfuscated things?

    Its way more easier than that copy the g() method in entity horse class remove the parts that give an error that that field isn't there. and done. Thats why I said you just need to look at the EntityHorse class but any way I'll link your tutorial for 1.7 users

    @ChipDev done https://funergy.me/screenshot/r01s0c6k0P2QrzCiDdsAb2BIu.png

    Apply the same calculations to the dragon's general move method (or something of the like). I answered a similar question in my old thread ;D

    @DSH105
    Any examples? I'm not sure of the certain methods of its body and movement

    Funergy

    @CactusComboPvP The method is m(). I think we need to edit the complex parts
    Code:
            this.children = new EntityComplexPart[]{this.bl = new EntityComplexPart(this, "head", 6.0F, 6.0F), this.bm = new EntityComplexPart(this, "body", 8.0F, 8.0F), this.bn = new EntityComplexPart(this, "tail", 4.0F, 4.0F), this.bo = new EntityComplexPart(this, "tail", 4.0F, 4.0F), this.bp = new EntityComplexPart(this, "tail", 4.0F, 4.0F), this.bq = new EntityComplexPart(this, "wing", 4.0F, 4.0F), this.br = new EntityComplexPart(this, "wing", 4.0F, 4.0F)};

    Not unless you want the player to control each of the dragon components separately. Here's a sample of what I wrote a while ago for this in EchoPet. It's not ideal, but it should give you an idea of how it can be done.

    Hey I'm wondering on how to set up my EditedPig Class.
    Any examples on how to use the NMSUtils method?

    Funergy

    @Max604 Well, there are plenty of tutorials how you can setup a custom entity. Just search on google.

    Max604

    @Fungergy they aren't set up for 1.8.3
     
  16. Offline

    Funergy

    @Max604 Setting up the class is the same on 1.7 and 1.8
    create a class let it extend a living entity.

    public class CustomEntity extends EntityZombie

    and then you will need to add 1 method

    public CustomEntity(World w){super(w);}

    I dont know right now if the super is right. I'm not on my pc right now.

    Hey, I have used this method and DSH's method to try and ride an Endermite, but neither of the seem to work. Does this method only work for certain mobs?

    Funergy

    @Zombie_Striker This only works for 1.8 version. 1.8.3 doesnt work because of the re-obfuscation.
    I have the newer version. I will give it you asap :p.

    EDIT: This should be working.
    Code:
    @Override
    public void g(float f, float f1) {
    if(this.passenger != null && this.passenger instanceof EntityHuman) {
    this.lastYaw = this.yaw = this.passenger.yaw; this.pitch = this.passenger.pitch * 0.5F; this.setYawPitch(this.yaw, this.pitch); this.aK = this.aI = this.yaw;f = ((EntityLiving)this.passenger).aZ * 0.5F;f1 = ((EntityLiving)this.passenger).ba; if(f1 <= 0.0F) {
    f1 *= 0.25F;}
    Field jump = null; try {
    jump = EntityLiving.class.getDeclaredField("aY");} catch (NoSuchFieldException e1) {
    // TODO Auto-generated catch blocke1.printStackTrace();} catch (SecurityException e1) {
    // TODO Auto-generated catch blocke1.printStackTrace();}
    jump.setAccessible(true); if (jump != null) { // Wouldn't want it jumping while on the ground would we?try {
    if (jump.getBoolean(this.passenger)) {
    
    double jumpHeight = 0.5D; this.motY = jumpHeight; // Used all the time in NMS for entity jumping}
    } catch (IllegalAccessException e) {
    e.printStackTrace();}
    }
    this.S = 1.0F; this.aM = this.bI() * 0.1F; if(!this.world.isClientSide) {
    this.k((float)this.getAttributeInstance(GenericAttributes.d).getValue()); super.g(f, f1);}
    
    this.aA = this.aB; double d0 = this.locX - this.lastX; double d1 = this.locZ - this.lastZ; float f4 = MathHelper.sqrt(d0 * d0 + d1 * d1) * 4.0F; if(f4 > 1.0F) {
    f4 = 1.0F;}
    
    this.aB += (f4 - this.aB) * 0.4F; this.aC += this.aB;} else {
    this.S = 0.5F; this.aM = 0.02F; super.g(f, f1);}
    
    }

    @Funergy Fields and methods such as "aM" "isClientSided" "bI" "aB" "aZ" and "ba" are coming up as undefined.
    The version I am using is git-Spigot-8a983f9-e81edfc (MC: 1.8)

    Where do you get the horse class from?

    Is it from the mincraft.jar or am I missing something?
     
  23. Offline

    Funergy

    @BurnerDiamond Net.Minecraft.server from Spigot. Spigot imports the minecraftserver.jar from minecraft.net

    One more question, how is my custom entity supposed to be. This is how I have it so far:

    The problem is that it comes, but doesn't move at all. Any help?

    Hi, I've just tried to use this, and the chicken rotates like it's supposed to, but it doesn't move, any help?

    Here is my full class:

    New question, I basically had to wait for the mob to update, any idea why and how to fix it?

    Hello,

    I have a problem with my custom mob, the bat doesn't spawn.

    RideAbleBat class:
    Code:
    public class RideAbleBat extends EntityBat
    {
      public RideAbleBat(World world, Player player)
      {
        super(world);
        this.rider = player;
        this.setSize(10, 10);
      }
     
      Player rider = null;
     
      @Override
      public void g(float sideMot, float forMot)
      {
        if ((this.passenger == null) || (!(this.passenger instanceof EntityHuman)))
        {
          super.g(sideMot, forMot);
          this.S = 0.5F;
          return;
        }
        EntityHuman human = (EntityHuman)this.passenger;
        this.lastYaw = (this.yaw = this.passenger.yaw);
        this.pitch = (this.passenger.pitch * 0.5F);
        this.setYawPitch(this.yaw, this.pitch);
        this.aK = (this.aM = this.yaw);
        this.S = 1.0F;
       
    
        sideMot = ((EntityLiving)this.passenger).aZ * 0.5F;
        forMot = ((EntityLiving)this.passenger).ba;
        if (forMot <= 0.0F) {
          forMot *= 0.25F;
        }
        sideMot *= 0.75F;
       
        float speed = 0.35F;
       
    
        f(speed);
        super.g(sideMot, forMot);
        try
        {
          Field jump = null;
          jump = EntityLiving.class.getDeclaredField("aY");
          jump.setAccessible(true);
          if ((jump != null) && (this.onGround)) {
            if (jump.getBoolean(this.passenger))
            {
              double jumpHeight = 0.5D;
              this.motY = jumpHeight;
            }
          }
        }

    Code for spawning :
    Code:

    Can you help me ?
    Good day.

    @Quaro I'm not sure what it does right now. Because its been a long time I've been working on Bukkit plugins.
    But Its needed.

    It's a final boolean which indicates whether it's running on the client side or server side, so it doesn't have any use in a server side Bukkit plugin.
