Does anyone know how to do something like this? xD

Does anyone know how to do this? If you have any method, then please share! Only the potions thing.

 

@DoggyCode™ Maybe that's just me but I don't understand what you are looking for. Explain please.

 

@DoggyCode™
Does that show the potions of the player? If so, you can create an inventory and put an itemstack with the active potions as lore in it (Player#getActivePotionEffects()) in the inventory.

 

Yeh, it's the potion effects of a player... but I want it all attached to one item, in the lore. Like displayed in the picture..

For example:

ITEM
Speed IV (time left)
Regeneration III (time left)

and so on, like in the lore, under each other.

For the roman numbers, I once created this method that you could use (goes up to 100 only):

Code (open) Code (close)

Code:

    private String toRomanNumbers(int value) {
        if(value == 100) return "" + '\u262f'; //Yin Yang
        String s = ""+value;
        int len0 = Integer.parseInt("" + s.charAt(0));
        int len1 = Integer.parseInt("" + (value >= 10 ? s.charAt(1) : s.charAt(0)));
        String out = "";
        if(value >= 10) {
            switch(len0) {
            case 1: out += "X"; break;
            case 2: out += "XX"; break;
            case 3: out += "XXX"; break;
            case 4: out += "XL"; break;
            case 5: out += "L"; break;
            case 6: out += "LX"; break;
            case 7: out += "LXX"; break;
            case 8: out += "LXXX"; break;
            case 9: out += "XC"; break;
            }
        } {
            switch(len1) {
            case 1: out += "I"; break;
            case 2: out += "II"; break;
            case 3: out += "III"; break;
            case 4: out += "IV"; break;
            case 5: out += "V"; break;
            case 6: out += "VI"; break;
            case 7: out += "VII"; break;
            case 8: out += "VIII"; break;
            case 9: out += "IX"; break;
            }
        }
        return out;
    }

For the lore you could do something like this

Code:

List<String> lore = new ArrayList<>();
for(PotionEffect effect : player.getActivePotionEffects()) {
  String name = effect.getType().name().toLowerCase();
  name = name.substring(0, 1).toUpperCase() + name.substring(1);
  long left = effect.getDuration() * 50L; //Ticks to milliseconds
  Calendar time = Calendar.getInstance();
  time.setTimeInMillis(left);
  String timeLeft = new SimpleDataFormat("someformatstring").format(time);
  String line = name + " " + toRomanNumbers(effect.getAmpflier()) + "(" + timeLeft + ")";
  lore.add(line);
}

Visit this link for possible date formats.

 

@megamichiel Thanks, but I still get one error:

 

Its SimpleDateFormat not data

 

Huh?.

@poepdrolify

 

@DoggyCode™ Use SimpleDateFormat, not SimpleDataFormat(no such thing).

 

@poepdrolify
oh woopsy my bad

 

Ok, but do you now know how I can add this to a item? This lore?

Code:

  //Active Potions Effects
  List<String> lore = new ArrayList<>();
  for(PotionEffect effect : p.getActivePotionEffects()) {
  String name = effect.getType().getName().toLowerCase();
  name = name.substring(0, 1).toUpperCase() + name.substring(1);
  long left = effect.getDuration() * 50L; //Ticks to milliseconds
  Calendar time = Calendar.getInstance();
  time.setTimeInMillis(left);
  String timeLeft = new SimpleDateFormat("someformatstring").format(time);
  String line = name + " " + toRomanNumbers(effect.getAmplifier()) + "(" + timeLeft + ")";
  lore.add(line);
  }

@megamichiel btw, that roman numbers thing, thanks!

 

Code:

ItemStack is = new ItemStack(Material.POTION);
ItemMeta im = is.getItemMeta();
im.setLore(lore)
im.setDisplayName("lol");
is.setItemMeta(im);

Not tested but should work

 

I tried... It worked, the item was there and everything.. until I added a potion effect to the player.. the inventory won't open and I get this error in the console.

@poepdrolify

bump

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

 

@DoggyCode™ tell us which error.

 

It says that it could to pass PlayerInteractEntityEvent from (plugin_name) (plugin_version).

 

@DoggyCode™
That's a simple EventException, send us the stacktrace. If you're using windows console you can right click and click "Mark" to select stuff.
EDIT: I'm guessing you left the "someformatstring" there.

 

I'll just give you what I have:

Code:

    private String toRomanNumbers(int value) {
    if(value == 100) return "" + '\u262f';
    String s = ""+value;
    int len0 = Integer.parseInt("" + s.charAt(0));
    int len1 = Integer.parseInt("" + (value >= 10 ? s.charAt(1) : s.charAt(0)));
    String out = "";
    if(value >= 10) {
    switch(len0) {
    case 1: out += "X"; break;
    case 2: out += "XX"; break;
    case 3: out += "XXX"; break;
    case 4: out += "XL"; break;
    case 5: out += "L"; break;
    case 6: out += "LX"; break;
    case 7: out += "LXX"; break;
    case 8: out += "LXXX"; break;
    case 9: out += "XC"; break;
    }
    } {
    switch(len1) {
    case 1: out += "I"; break;
    case 2: out += "II"; break;
    case 3: out += "III"; break;
    case 4: out += "IV"; break;
    case 5: out += "V"; break;
    case 6: out += "VI"; break;
    case 7: out += "VII"; break;
    case 8: out += "VIII"; break;
    case 9: out += "IX"; break;
    }
    }
    return out;
    }

  public Inventory InspectPlayer(Player p){
  //Defining the Player interface above
  //Creating a Player Inventory and setting the name  
  Inventory inv = Bukkit.createInventory(p, 18,"§6Inspecting: §e" + p.getName());
  
  //Making and editing properties of custom item
  //You Can Copy paste this part as much items as you want and set each item to a different slot in the inventory
  
  
  //Active Potions Effects
  List<String> lore = new ArrayList<>();
  for(PotionEffect effect : p.getActivePotionEffects()) {
  String name = effect.getType().getName().toLowerCase();
  name = name.substring(0, 1).toUpperCase() + name.substring(1);
  long left = effect.getDuration() * 50L; //Ticks to milliseconds
  Calendar time = Calendar.getInstance();
  time.setTimeInMillis(left);
  String timeLeft = new SimpleDateFormat().format(time);
  String line = name + " " + toRomanNumbers(effect.getAmplifier()) + "(" + timeLeft + ")";
  lore.add(line);
  
  }
  
  //Active Potion Effects Item
  ItemStack potionEffects = new ItemStack(Material.BREWING_STAND_ITEM);
  ItemMeta im = potionEffects.getItemMeta();
  im.setLore(lore);
  im.setDisplayName("§6Active Potion Effects");
  potionEffects.setItemMeta(im);

then under a lot of things you don't have to see, I have:

Code:

inv.setItem(8, potionEffects);

@DoggyCode™
Just what I guessed.

Code:

String timeLeft = new SimpleDateFormat().format(time);

http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

 

Wait, should I just copy what you wrote there and it should be all good?
