-''ToolMaterial''s do //not// have to be registered. A good way to pass them out to tools that require them is by keeping an instance somewhere (and then referencing it when you need it). In this case, we will put our instance at the top of the Tool Material class: +

-''PotatoToolMaterial'' can now be referenced with ''PotatoToolMaterial.INSTANCE''.+''PotatoToolMaterial'' can now be referenced with ''PotatoToolMaterial.INSTANCE''. Alternatively, you can implement an enum similar to vanilla's ''ToolMaterials'' class that implements ''ToolMaterial'', which provides the instance and also allows easy creation of multiple tool materials.
  
-==== Creating Tools ====+===== Creating Tools Items =====
  
-All base tool classes (''PickaxeItem'', ''ShovelItem'', ''HoeItem'', ''AxeItem'', ''SwordItem'') require a ''ToolMaterial'', an attack speed (float), an additional attack damage amount (int), and an ''Item.Settings'' instance.+**In newer versions, all base tool class constructors are public and can be used directly to register the item.** This constructor lets you specify attack damage and attack speed of the tool. Remember they should be registered (see [[items]] tutorial).
  
-<code java [enable_line_numbers=true]> +<yarncode java> 
-public static ToolItem POTATO_SHOVEL = new ShovelItem(PotatoToolMaterial.INSTANCE, 1.5F, -3.0F, new Item.Settings().group(ItemGroup.TOOLS)); +public final class TutorialItems {

-</code>+    public static class_1831 POTATO_AXE = new AxeItem(PotatoToolMaterial.INSTANCE, 7.0F, -3.2F, new FabricItemSettings());

 +===== Creating Tool Subclasses ===== 
 + 
 +**This section is not necessary in the current version of Fabric.** This is a good way to implement special attributes or behaviors for your tool, however.
  
-`PickaxeItem` , `HoeItem` and `AxeItem` have protected constructors, which means you will need to create your own sub-class with a public constructor:  +In older versions, all base tool classes (''<yarn class_1810>'', ''<yarn class_1821>'', ''<yarn class_1794>'', ''<yarn class_1743>'', ''<yarn class_1829>'') require a ''<yarn class_1832>'', an attack speed (float), an additional attack damage amount (float for <yarn class_1743>; int for the rest), and an ''<yarn class_1792.class_1793>'' instance. 
-<code java [enable_line_numbers=true]> + 
-public class CustomPickaxeItem extends PickaxeItem { +''<yarn class_1810>'' , ''<yarn class_1794>'' and ''<yarn class_1743>'' have protected constructors, which means you will need to create your own classes with public constructors:  
-    public PickaxeSubclass(ToolMaterial material, int attackDamage, float attackSpeed, Settings settings) {+<yarncode java [enable_line_numbers=true]> 
 +public class CustomPickaxeItem extends class_1810 { 
 +    public CustomPickaxeItem(class_1832 material, int attackDamage, float attackSpeed, class_1793 settings) {
         super(material, attackDamage, attackSpeed, settings);         super(material, attackDamage, attackSpeed, settings);
     }     }
 } }
-</code> +</yarncode>
- +
-Using the custom subclass: +
-<code java> +
-public static ToolItem POTATO_PICKAXE = new CustomPickaxeItem(PotatoToolMaterial.INSTANCE, 1, -2.8F, new Item.Settings().group(ItemGroup.TOOLS)); +
-public static ToolItem POTATO_AXE = new CustomAxeItem(PotatoToolMaterial.INSTANCE, 7.0F, -3.2F, new Item.Settings().group(ItemGroup.TOOLS)); +
-public static ToolItem POTATO_HOE = new CustomHoeItem(PotatoToolMaterial.INSTANCE, 7, -3.2F, new Item.Settings().group(ItemGroup.TOOLS)); +
-</code> +
- +
-If you want to add any special attributes or behaviors to your tool, create a subclass that extends one of the base tool classes, and override any required methods. +
- +
-==== Registering Tools ====+
  
-For a recap on registering items, read through the item tutorial [[tutorial:items|here]].+Using the public classes: 
 +<yarncode java> 
 +    public static class_1831 POTATO_PICKAXE = new CustomPickaxeItem(PotatoToolMaterial.INSTANCE, 1, -2.8F, new class_1792.class_1793()); 
 +    public static class_1831 POTATO_AXE = new CustomAxeItem(PotatoToolMaterial.INSTANCE, 7.0F, -3.2F, new class_1792.class_1793()); 
 +    public static class_1831 POTATO_HOE = new CustomHoeItem(PotatoToolMaterial.INSTANCE, 7, -3.2F, new class_1792.class_1793());
