Solved Getting Thrown Snowball Lore

I am writing a pokeball plugin where when a mob is hit by a snowball, the mob drops a snowball with all of its data stored in its lore. I am trying to get the Lore from the thrown snowball and I can't figure out how. Is this possible or should I take a different approach?

andstu code?

 

andstu You listen to PlayerInteractEvent, you get the itemstack, you get the ItemMeta, you get the Lore and throw a snowball (and set the player as the shooter). You put put it in a HashMap<UUID, List<String>>, where you put the UUID of the player, and the lore. Then you listen to the ProjectileHitEvent, you check if it's a snowball, you get the shooter, you get the lore from the HashMap, then you spawn the horse with the lore at the Location (Y + 2).
Hope that helps,

Projectile extends Metadatable, which means you can get and set Metadata on it. When you throw the snowball, set its Metadata to match the lore of it's ItemStack counterpart.

 

That's also a way around it
andstu You can add Metadata to the pokeball, so you add the List<String> to the pokeball's metadata but it will be resetted every time you shutdown your server/reload your server...

 

DevilMental
That doesn't seem like a big deal, since the projectile's lifetime is pretty short.

 

I meant it for the Item, the Projectile Metadata was a pretty good idea

 

Are HashMaps usable in between Methods? So I could create the HashMap in one method and then use it in another? DevilMental

maybe this work, this one detects throwing snowball to pig (not tested)

Code:java

    @EventHandler
    public void onEntityDamageByEntity(EntityDamageByEntityEvent e) {
        if (e.getDamager().getType() == EntityType.SNOWBALL) {
            if(!(e.getEntity() instanceof Player)){
                if(e.equals(EntityType.PIG)){
                        ItemStack itemStack = new ItemStack(Material.SNOW_BALL);
                        ((HumanEntity) e.getDamager()).getInventory().addItem(itemStack);
                }
            }
        }
    }

 

Wingas I already detected when and what the snowball hits. It saves the data of the mob that it hits into the item's lore. I just need a way to get the information from the lore in order to respawn the mob.

 

andstu If you put the HashMap into the class and you declare it public (static or not) then yes you can access the hashmap everywhere.

 

DevilMental I have never used a hashmap before . Is this a proper declaration?

Code:java

public HashMap<String, List<String>> lore = new HashMap<String, List<String>>();

Also, how do I get the UUID of a player? DevilMental Dragonphase Wingas

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

andstu

Code:java

Player.getUniqueId();

 

DevilMental Dragonphase How would I spawn a custom entity Horse h? Here is my code:

Code:java

    public void spawnhorse(org.bukkit.World world, Location loc, List<String> l){
    Horse h = null;
    h.setCustomName(l.get(1));
    Variant v = Variant.valueOf(l.get(2));
    h.setVariant(v);
    Style style = Style.valueOf(l.get(3));
    h.setStyle(style);
    org.bukkit.entity.Horse.Color color = org.bukkit.entity.Horse.Color.valueOf(l.get(4));
    h.setColor(color);
    double jump = Double.parseDouble(l.get(5));
    h.setJumpStrength(jump);
    double speed = Double.parseDouble(l.get(6));
    AttributeInstance s = ((EntityInsentient)((CraftLivingEntity)h).getHandle()).getAttributeInstance(GenericAttributes.d);
    s.setValue(speed);
    //Creds to ToastHelimi for Speed setting
    h.setTamed(Boolean.valueOf(l.get(7)));
    double health = Double.parseDouble(l.get(8));
    h.setMaxHealth(health);
    spawnEntity(loc, h);

 

andstu Actually I am not sure about the lore.get(1) but use lore[0] because an array starts at 0, not at one. Also, to spawn an horse, don't set it to null, but spawn with the world.spawnEntity and cast it to Horse.

 

DevilMental hmm. Here it says to use lore.get(x). I need to get the second element in the array because the first one just says what type of mob it is. Am I doing the spawnEntity wrong? I looked up the syntax and I think this should be correct but I just get errors under EntityType HORSE...

Code:java

Horse h = (Horse) world.spawnEntity(loc, EntityType HORSE);

 

andstu It's EntityType.HORSE

 

It's because DevilMental obviously didn't read your Code

to acces an Array, yes you need to do array[index] however as you pass on a List<String> and not an Array it has to be done via .get(index)

 

DevilMental I get an error under HORSE that says "HORSE cannot be resolved or is not a field"

 

andstu Just replace the space in between EntityType Horse with a .

 

andstu It's EntityType.HORSE (with the point)
http://jd.bukkit.org/rb/apidocs/org/bukkit/entity/EntityType.html#HORSE

 

DevilMental I know when I write EntityType.HORSE I get an error. do I have to declare it or something?

Code:

Code:java

Horse h = (Horse) world.spawnEntity(loc, EntityType.HORSE);

Under "HORSE" I get the error "HORSE cannot be resolved or is not a field"

andstu Did you import org.bukkit.entity.EntityType ?

 

DevilMental WOW. I feel stupid. Thanks. I imported the wrong one.

 

andstu Your welcome

 

DevilMental Now I just gotta do the same thing for every other mob in the game and I am done!

 

andstu What about adding the EntityType into the lore ? So that you don't need to repeat the same code for every entity

 

DevilMental Good Idea! I will try that.

DevilMental Dragonphase I have a string that has the name of the owner of a cat/dog, is there a way to turn that back into an AnimalTamer variable?
