get item category

hello
i will try to have the item gategory same as the creative inventory
for exemple : diamond sword -> combat ; stick -> materials

is it possible ? if is it how can i get it ?

 

I Don't Think There Is A Method For This...
But if you have enough free time, you can just make a switch statment for each item That exists in the game.

Not a very efficient way, but still the only one i can think of.

Or you use lovely Reflection. The calls are not optimized, rely on version dependend imports and are only as a proof-of-concept.

Code:java

    @EventHandler
    public void onPlayerHit(PlayerInteractEvent event) {
        if (!event.hasItem()) {
            return;
        }
        ReflectResponse<Object> value;
        if (event.getItem().getType().isBlock()) {
            // Block
            Block block = CraftMagicNumbers.getBlock(event.getMaterial());
            value = ReflectionUtil.getFieldValue(Block.class, block, (field) -> field.getType() == CreativeModeTab.class);
        } else {
            // Item
            Item item = CraftMagicNumbers.getItem(event.getItem().getType());
            value = ReflectionUtil.getFieldValue(Item.class, item, (field) -> field.getType() == CreativeModeTab.class);
        }
        if (value == null || !value.isValuePresent()) {
            event.getPlayer().sendMessage(TextUtils.colorize("&cTab not found!"));
            return;
        }
        String creativeTabName = getCreativeTabName(value);
        if (creativeTabName == null) {
            event.getPlayer().sendMessage(TextUtils.colorize("&cTab name not found!"));
        } else {
            event.getPlayer().sendMessage(TextUtils.colorize("&7The tab is: &a" + creativeTabName + "&7."));
        }
    }
 
    private String getCreativeTabName(ReflectResponse<Object> value) {
        if (value.isValuePresent()) {
            CreativeModeTab tab = (CreativeModeTab) value.getValue();
            ReflectResponse<Object> name = ReflectionUtil.getFieldValue(CreativeModeTab.class, tab, new MemberPredicate<Field>()
                      .withModifiers(Modifier.FINAL, Modifier.PRIVATE).and(field -> field.getType() == String.class));
            if (name.isValuePresent()) {
                String category = (String) name.getValue();
                return category;
            }
        }
        return null;
    }

(@timtower Does the file upload here only doesn't work for me? Could easily be the case.)

 

@timtower
Nah, just a bit of digging in the client and server code. Thanks though
It is a nice concept, but I can't really find any application for it xD

Ah, I see. It has worked but since a month or so it doesn't anymore. I will check with a clean browser and if it doesn't work make a thread about it. Thanks


@rushr93
If you don't really understand what I did, I can probably make a SSCCE for it, you can use.
