Frozen Mobs

I am trying to make a plugin where you run a command and it spawns a chicken or any other mob that is frozen and cannot move and twitch. Its just frozen. Something like this.

 

Set their velocities to -1 using this method, and set their jumping to -1 as well.

Like this?

Code:

 private static final UUID movementSpeedUID = UUID.fromString("206a89dc-ae78-4c4d-b42c-3b31db3f5a7c");
     
       @EventHandler(priority = EventPriority.MONITOR, ignoreCancelled = true)
       public void onEntitySpawn(CreatureSpawnEvent event){
           LivingEntity entity = event.getEntity();
     
           if (entity.getType() == EntityType.VILLAGER){
               EntityInsentient nmsEntity = (EntityInsentient) ((CraftLivingEntity) entity).getHandle();
               AttributeInstance attributes = nmsEntity.getAttributeInstance(GenericAttributes.d);
       
               AttributeModifier modifier = new AttributeModifier(movementSpeedUID, "<plugin_name> movement speed multiplier", -1d, -1);
       
               attributes.b(modifier);
               attributes.a(modifier);
           }
       }

if so it doesn't work.

 

You can:
Add a slowness effect to it like the code below
Teleport the mob to a location every amount of ticks

Code:

Villager myMob = (Villager) player.getWorld().spawnEntity(player.getLocation(), EntityType.VILLAGER);

myMob.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, Integer.MAX_VALUE, 100));

i think that'll work.

 

He would still be able to move. He would be able to turn.
Also you would see the slowness particles.

 

Code:

    public void setEntitySpeed(Entity e,double speed){
        LivingEntity entity = (LivingEntity) e;
       
        EntityInsentient nmsEntity = (EntityInsentient) ((CraftLivingEntity) entity).getHandle();
        AttributeInstance attributes = nmsEntity.getAttributeInstance(GenericAttributes.d);
        AttributeModifier modifier = new AttributeModifier(movementSpeedUID, "<plugin_name> movement speed multiplier", speed, 1);
        attributes.b(modifier);
        attributes.a(modifier);
    }


//eslewhere
         setEntitySpeed(event.getEntity(), -10.0d);

This works...

 

Doesn't work. I think I'm putting it in wrong

Code:

 private static final UUID movementSpeedUID = UUID.fromString("206a89dc-ae78-4c4d-b42c-3b31db3f5a7c");
     
    public void setEntitySpeed(Entity e,double speed){
           LivingEntity entity = (LivingEntity) e;
         
           EntityInsentient nmsEntity = (EntityInsentient) ((CraftLivingEntity) entity).getHandle();
           AttributeInstance attributes = nmsEntity.getAttributeInstance(GenericAttributes.d);
           AttributeModifier modifier = new AttributeModifier(movementSpeedUID, "<plugin_name> movement speed multiplier", speed, 1);
           attributes.b(modifier);
           attributes.a(modifier);
       }
     
       @EventHandler(priority = EventPriority.MONITOR, ignoreCancelled = true)
       public void onEntitySpawn(CreatureSpawnEvent event){
           LivingEntity entity = event.getEntity();
     
           if (entity.getType() == EntityType.VILLAGER){
               EntityInsentient nmsEntity = (EntityInsentient) ((CraftLivingEntity) entity).getHandle();
               AttributeInstance attributes = nmsEntity.getAttributeInstance(GenericAttributes.d);
       
               AttributeModifier modifier = new AttributeModifier(movementSpeedUID, "<plugin_name> movement speed multiplier", -1d, -1);
       
               attributes.b(modifier);
               attributes.a(modifier);
               
           }
       }

 

Well, you're not actually calling the method and you still have the old, broken lines in you Spawn event.

Are you new to Java, or did you just overlook that?
