1.15.2 Errors in my Plugin

Good, I'm a little cold because it's been a while since I played Java and Minecraft plugins, so I have several errors, to see if please someone help me to solve them


Here I leave the pastebin with the types of errors that arise and see if someone gives me a solution please

So what solution do you recommend for such cases, remove the parts of the id and not change it for anything? just remove them?

 

that for what kind of pastebin error?

Could you give me an example and I fix the others?

thanks

 

forgive me for being so short minded now but I still don't understand it xD I mean in this case that I expose you now how would you make the change?

Code (Java):

i = f.createItem(p.getName(), item, 1);
            meta = i.getItemMeta();
            id = i.getTypeId()+((i.getDurability() > 0)?":"+i.getDurability():"");
            precioBuy = f.getPrice(item);
            precioSell = precioBuy*f.SELLRATE/f.MULTIPLIER;

How would you solve the getTypeId in this case?

 

I have solved the issue of the ids but I still have several errors that I cannot solve
Let's see if someone can solve them please

In this code the part doesnt work "" ItemStack stack = new ItemStack(getId(item)); ""

Code (Java):

public ItemStack createItem(String p, String item, int size){
        ItemStack stack = new ItemStack(getId(item));
        short data = (short)getData(item);
        if(haveData(item)){
            stack.setDurability(data);
        }

In this code the part doesnt work "" int maxStack = Material.getMaterial(getId(item)).getMaxStackSize(); ""

Code (Java):

 public List<ItemStack> createItems(String p, String item, int num){
        List<ItemStack> items = new ArrayList<>();
        int maxStack = Material.getMaterial(getId(item)).getMaxStackSize();
        if(num%maxStack > 0){
            items.add(createItem(p, item, num%maxStack));
            num -= num%maxStack;
        }
        for(int i = 0; i < num/maxStack; i++){
            items.add(createItem(p, item, maxStack));
        }
        return items;
    }

In this code the part doesnt work "" if(!(event.getInventory().getName() == getShopName())){ ""

Code (Java):

private void onClickInventory(InventoryClickEvent event){
        // TEST long timeI = System.nanoTime();
        if(event.getInventory().getType() != InventoryType.CHEST){
            return;
        }
        if(event.getInventory().getSize() != FactoryGui.SIZE){
            return;
        }
        if(!(event.getInventory().getName() == getShopName())){
            return;
        }

the getid that comes out in the errors comes from this method

Code (Java):

    private int getId(String item){
        int id = getCache().getInt("item."+item+".id");
        if (id == 0) {
            SpiceCraft.log("Item: " + item + "not found in shop.yml.");
        }
        return id == 0 ? 1 : id;
    }

I would be very grateful if someone would help me with these 3 errors and give me the solution or example of how to fix it regards
