 ====== Adding Armor ======
-==== Introduction ====
+===== Introduction =====
 While armor is a bit more complicated to implement than a normal block or item, once you understand it, it becomes simple to implement. To add armor, we'll first make a CustomArmorMaterial class, then register the items. We'll also take a look at how to texture them. There's a special chapter at the end of this document that explains how to add knockback to the armor, since the method is only accessible through a mixin (as of 1.16.3).

 Since new armor needs to be set with a new name (as well as extra things like armor points and durability), we'll have to create a new class for our CustomArmorMaterial.

 Now that you have the basics of the armor material class, let's register your armor items in a new class we'll simply call RegisterItems.
-==== Creating Armor Items ====
+===== Creating Armor Items =====
-We're gonna make a new class called RegisterItems to implement your new armor pieces. This will also be the place to, for example, register tools, if you're making a new item like an ingot (We'll refer to this as a "Custom_Material"). This setup will also put the items on a new Creative tab, but you're free to delete that part.
+In the [[item]] tutorial, we've created a class ''TutorialItems'' for items in the mod. Here we place them here, and use the convenient ''register'' method we've introducted in the [[item]] tutorial.
-The syntax of groups is //.<yarn method_7892>(YourModName.YOUR_MOD_NAME_BUT_IN_CAPS_GROUP)//. I'll be referring to it as ExampleMod:
 <yarncode java [enable_line_numbers="true"]>
-public class RegisterItems {
+public final class TutorialItems {
+    // [...]
     public static final class_1741 CUSTOM_ARMOR_MATERIAL = new CustomArmorMaterial();
-    public static final class_1792 CUSTOM_MATERIAL = new CustomMaterialItem(new class_1792.class_1793().method_7892(ExampleMod.EXAMPLE_MOD_GROUP));
+    public static final class_1792 CUSTOM_MATERIAL = register(new CustomMaterialItem(new class_1792.class_1793()), "custom_material");
     // If you made a new material, this is where you would note it.
-    public static final class_1792 CUSTOM_MATERIAL_HELMET = new class_1738(CUSTOM_ARMOR_MATERIAL, class_1304.field_6169, new class_1792.class_1793().method_7892(ExampleMod.EXAMPLE_MOD_GROUP));
+    public static final class_1792 CUSTOM_MATERIAL_HELMET = register(new class_1738(CUSTOM_ARMOR_MATERIAL, class_1304.field_6169, new class_1792.class_1793()), "custom_material_helmet");
-    public static final class_1792 CUSTOM_MATERIAL_CHESTPLATE = new class_1738(CUSTOM_ARMOR_MATERIAL, class_1304.field_6174, new class_1792.class_1793().method_7892(ExampleMod.EXAMPLE_MOD_GROUP));
+    public static final class_1792 CUSTOM_MATERIAL_CHESTPLATE = register(new class_1738(CUSTOM_ARMOR_MATERIAL, class_1304.field_6174, new class_1792.class_1793()), "custom_material_chestplate");
-    public static final class_1792 CUSTOM_MATERIAL_LEGGINGS = new class_1738(CUSTOM_ARMOR_MATERIAL, class_1304.field_6172, new class_1792.class_1793().method_7892(ExampleMod.EXAMPLE_MOD_GROUP));
+    public static final class_1792 CUSTOM_MATERIAL_LEGGINGS = register(new class_1738(CUSTOM_ARMOR_MATERIAL, class_1304.field_6172, new class_1792.class_1793()), "custom_material_leggings");
-    public static final class_1792 CUSTOM_MATERIAL_BOOTS = new class_1738(CUSTOM_ARMOR_MATERIAL, class_1304.field_6166, new class_1792.class_1793().method_7892(ExampleMod.EXAMPLE_MOD_GROUP));
+    public static final class_1792 CUSTOM_MATERIAL_BOOTS = register(new class_1738(CUSTOM_ARMOR_MATERIAL, class_1304.field_6166, new class_1792.class_1793()), "custom_material_boots");
 }
 </yarncode>
-Now that your items are properly created, let's register them and give them proper names. Your first parameter is going to be your namespace, which is your mod ID, and then next one the name you want to give to your item.
+Your armor items are done. Now we'll just create a separate [[itemgroup|item group]] for that.
-We'll be writing this right below your last <yarn class_1738>.
 <yarncode java [enable_line_numbers="true"]>
-public static void register() {
+public final class TutorialItemGroups {
-    class_2378.method_10230(class_2378.field_11142, new class_2960("examplemod", "custom_material"), CUSTOM_MATERIAL);
+    public static final class_1761 TEST_GROUP = FabricItemGroup.builder()
-    class_2378.method_10230(class_2378.field_11142, new class_2960("examplemod", "custom_material_helmet"), CUSTOM_MATERIAL_HELMET);
+        .icon(() -> new class_1799(TutorialItems.CUSTOM_MATERIAL)) // This uses the model of the new material you created as an icon, but you can reference to whatever you like
-    class_2378.method_10230(class_2378.field_11142, new class_2960("examplemod", "custom_material_chestplate"), CUSTOM_MATERIAL_CHESTPLATE);
+        .displayName(Text.translatable("itemGroup.tutorial.test_group"))
-    class_2378.method_10230(class_2378.field_11142, new class_2960("examplemod", "custom_material_leggings"), CUSTOM_MATERIAL_LEGGINGS);
+        .entries((context, entries) -> {
-    class_2378.method_10230(class_2378.field_11142, new class_2960("examplemod", "custom_material_boots"), CUSTOM_MATERIAL_BOOTS);

+                .add(CUSTOM_MATERIAL_LEGGINGS)
+                .add(CUSTOM_MATERIAL_BOOTS);
+        })
+        .build();
+    public static void initialize() {
+        // Since 1.21:
+        Registry.register(Registries.ITEM_GROUP, Identifier.of("tutorial", "test_group"), ITEM_GROUP);
+    }
 }
 </yarncode>
-Your armor items are done. Now we'll just call the Registry on our main class (and annotate the new group).
+If you did those above in the separate classes, remember to statically initialize the classes in your ''ModInitializer'', if you haven't done yet:
+<code java>
-<yarncode java [enable_line_numbers="true"]>
+public class ExampleMod implements ModInitializer {
-public static final class_1761 EXAMPLE_MOD_GROUP = FabricItemGroupBuilder.create(
+    [...]
-    new class_2960("examplemod", "example_mod_group"))
-    .icon(() -> new class_1799(RegisterItems.CUSTOM_MATERIAL)) // This uses the model of the new material you created as an icon, but you can reference to whatever you like
+    @Override
-    .build();
+    public void onInitialize() {
+        TutorialItems.initialize();
-@Override
+        TUtorialItemGroups.initialize();
-public void onInitialize() {
+    }
-    RegisterItems.register();
 }
-</yarncode>
+</code>
 That's it! Your armor should now exist in game, untextured still, but present and able to be given with /give.
 Now we'll be assigning the textures to each piece.
 ==== Texturing ====
 We're going to assume you
-  * Have the textures for each armor item (x_helmet.png, x_chestplate.png etc.)
+  * Have the textures for each armor item (''x_helmet.png'', ''x_chestplate.png'' etc.)
-  * Have the textures for the armor in body (x_layer_1.png and x_layer_2.png)
+  * Have the textures for the armor in body (''x_layer_1.png'' and ''x_layer_2.png'')
 And assign them to each armor item.

 Repeat with all armor items.
-To give your on-body armor a texture, simply place X_layer_1.png and X_layer_2.png (where X is the <yarn method_7694> argument you chose in your armor material class) into 'resources/assets/minecraft/textures/models/armor'.
+Generally, mod textures go under resources/assets/<modid>, however **armor textures go specifically in the minecraft directory**:

 If you followed everything, you should now be able to have a full armor set!
-====Adding Knockback Protection====
-And here comes the so very cursed!
-Mojang decided that they were not only going to hardcode <yarn method_24355>, but they were also gonna make it immutable! Fun stuff.
-To get around this, we're gonna make a mixin that goes into <yarn class_1738>. If this is your first time, [[tutorial:mixin_registration|here's how to register mixins on your fabric.mod.json]]
-We'll make a class called ArmorItemMixin, and write:
-<yarncode java [enable_line_numbers:"true"]>
-@Mixin (class_1738.class)
-public abstract class ArmorItemMixin {
-}
-</yarncode>
-Now we have to make a @Shadow to modify knockbackResistance, which is an <yarn class_1320>
-<yarncode java [enable_line_numbers:"true"]>
-@Mixin (class_1738.class)
-public abstract class ArmorItemMixin {
-	@Shadow @Final private static UUID[] MODIFIERS;
-	@Shadow @Final @Mutable private Multimap<class_1320, class_1322> attributeModifiers;
-	@Shadow @Final protected float knockbackResistance;
-}
-</yarncode>
-Next we @Inject our <yarn field_23718> into the <yarn class_1741> constructor.
-<yarncode java [enable_line_numbers:"true"]>
-@Mixin (class_1738.class)
-public abstract class ArmorItemMixin {
-    @Shadow @Final private static UUID[] MODIFIERS;
-    @Shadow @Final @Mutable private Multimap<class_1320, class_1322> attributeModifiers;
-    @Shadow @Final protected float knockbackResistance;
-    @Inject(method = "<init>", at = @At(value = "RETURN"))
-    private void constructor(class_1741 material, class_1304 slot, class_1792.class_1793 settings, CallbackInfo ci) {
-        UUID uUID = MODIFIERS[slot.method_5927()];
-        if (material == RegisterItems.CUSTOM_ARMOR_MATERIAL) {
-            ImmutableMultimap.Builder<class_1320, class_1322> builder = ImmutableMultimap.builder();
-            this.attributeModifiers.forEach(builder::put);
-            builder.put(
-                    class_5134.field_23718,
-                    new class_1322(uUID,
-                            "Armor knockback resistance",
-                            this.knockbackResistance,
-                            class_1322.class_1323.field_6328
-                    )
-            );
-            this.attributeModifiers = builder.build();
-        }
-    }
-}
-</yarncode>
-Now your armor has the knockback resistance value you assigned to it back on CustomArmorMaterial.
