SwordItem class not found?

[youkononame]

I was reading the guide for creating custom tools (https://docs.fabricmc.net/develop/items/custom-tools) and I noticed the use of the "SwordItem" class. IntelliJ could not automatically find a package to import it from and it didn't seem to appear in anywhere. I know this is written for 1.21.4 and I was on 1.21.5 but I can't imagine any drastic changes being made between those two versions.

Any way of fixing this? The ToolMaterial for Stone being passed to .applySwordSettings with 1f attackDamage and attackSpeed gave me the attack speed and damage of a pickaxe, and I couldn't find any alternatives. Help would be appreciated!

Lol. You underestimate how many changes Mojang makes behind the scenes. There is no SwordItem class anymore, you can just use Item while setting the sword settings appropriately on the item settings. You can ask on the Fabric discord if you need any further help.

It seems that it has been removed in 1.21.5. You can use new Item.Settings().sword(...) To create swords.
But I crashed when I was using it:

(Is it compliance to upload the crash report here?）

I think we should now have to put the tool properties and make it into a ToolItem.

public static final Item RIP_SWORD_ITEM = register(
    "rip_sword_item",
    settings -> new ToolItem(
        TOOL_MATERIAL,      // ToolMaterial
        new ToolAttributes.Builder()
            .damage(3.0f)
            .speed(-2.4f)
            .type(ToolAttributes.Type.SWORD)
            .build(),
        settings
    ),
    new Item.Settings()
);

[detectivelll]

You can check the Items.class code. This should work:

public static final Item YOUR_SWORD_ITEM = register(
            "your_sword_item",
            settings -> new Item(
                    settings.sword(ToolMaterial.WOOD,
                            3.0f,
                            -2.4f)
            ),
            new Item.Settings()
    );

[detectivelll]

By the way, if you want your sword to have sweeping attacks and enchantment capabilities, create a swords.json file here:
src/main/resources/data/minecraft/tags/item/
"swords.json" can be like this:

{
  "replace": false,
  "values": [
    "tutorialmod:your_sword_item"
  ]
}

[oniroo]

I've seen the up coming PR and I found that we can use this

public static final Item YOUR_SWORD_ITEM = register(
            "your_sword_item",
            Item::new,
            new Item.Settings().sword(...)     // Like this
    );
