Change head rotation without teleporting

Hi

How can you set an entity's head direction without teleporting it? Teleporting is glitchy.

There is no method for this for Bukkit, so you will either have to work with packets or with NMS.

Try this if you want to use packets.

I think this works with every living entity but players.

Code:

((CraftLivingEntity) livingEntity).getHandle().yaw = yourYaw;

 

I need it only for players, unfortunately :/

I've written the following code but the head movement is crazy and the player gets teleported wildly.

Code:

Location targetLoc = ent.getLocation();
             
                Location playerLoc = p.getLocation();
                Location eyeLoc = p.getEyeLocation();
             
                double tx = targetLoc.getX();
                double ty = targetLoc.getY();
                double tz = targetLoc.getZ();
             
                double ex = eyeLoc.getX();
                double ey = eyeLoc.getY();
                double ez = eyeLoc.getZ();
             
                double dx = tx - ex;
                double dy = ty - ey;
                double dz = tz - ez;
                double dxyz = Math.sqrt(Math.pow(dx, 2) + Math.pow(dy, 2) + Math.pow(dz, 2));
             
                float currentYaw = eyeLoc.getYaw();
                float currentPitch = eyeLoc.getPitch();
             
                float requiredYaw = (float) (-Math.atan2(dx, dz) * 180 / Math.PI); //(Math.acos(dx / dxz) * 180 / Math.PI);

                float requiredPitch = (float) (-Math.asin(dy / dxyz) * 180 / Math.PI);
             
                float yawDiff = requiredYaw - currentYaw;
                float pitchDiff = requiredPitch - currentPitch;
             
                float newYaw = currentYaw + (float) (yawDiff * 0.1);
                float newPitch = currentPitch + (float) (pitchDiff * 0.1);
             
                PacketPlayOutEntityLook packet = new PacketPlayOutEntityLook(p.getEntityId(), toPackedByte(newYaw), toPackedByte(newPitch), ((Entity) p).isOnGround());
             
                for(Player online : getServer().getOnlinePlayers())
                {
                    ((CraftPlayer) online).getHandle().playerConnection.sendPacket(packet);             
                }
