Help with lores (Probably a stupid question)

Hey there, I am creating a Custom Enchant plugin and all I need help with is when a player clicks a book on a item (all checks have been done) it adds a lore to the item WITHOUT removing any other the previous lores. This is the code I have right now for it:

Code:

 
ItemStack stack = e.getCurrentItem();

                    ItemMeta stackMeta = item.getItemMeta();

                    List<String> gettingLore = e.getCurrentItem().getItemMeta().getLore();

                     

                    oldLore = gettingLore.toString();

                     

                   

                int size = e.getCurrentItem().getItemMeta().getLore().size();

                e.getCurrentItem().getItemMeta().getLore().add(size,lore1);

I get this error in console:

Code:

Thanks for your help!

 

First of all, please read this to understand the error:
https://bukkit.org/threads/how-to-r...ubleshoot-your-own-plugins-by-yourself.32457/

Now, the way to add a String to the lore, is to get the lore (if any) and add a string to the List returned or if there is no lore, set the lore of the item to a list containing the enchantment name.

 

Ok, I have tried this in many ways but none work. Can you push me in the right direction of what I need to try to do?

EDIT: Furthermore I have read through your link and I have made sure that nothing is 'null' and that I have not tried to change anything that is null.

 

Post the error line

 

@Saracen147 If an item has no lore the lore returned by ItemMeta#getLore is null, you need to check first if the ItemMeta#hasLore

 

List<String> lore = new ArrayList<String>();
lore.add("Hi");

ItemStack apple = new ItemStack(Material.APPLE);
ItemMeta appleMeta = apple.getItemMeta();

appleMeta.setLore(lore);
apple.setItemMeta(appleMeta);


The lore will be 'Hi' and if you want to add color, do:
lore.add(ChatColor.(Color in Caps) + "Hi");
or
lore.add(ChatColor.translateAlternateColorcodes('&', "&(VALUE)Hi"));

The default color is a italicized purple.

First of all don't spoonfeed, it doesn't help:

Secondly, when you post code put it in code tags to sheink your post and make it more readable.
