== Usage with Blocks and Items ==

Block, Item, and a few other Minecraft classes have built-in translation keys used to display their names. These translation keys are specified by overriding <code>getTranslationKey()</code>. Item also has <code>getTranslationKey(ItemStack)</code> which can be overridden to provide different translation keys depending on <code>ItemStack</code> NBT.

Item also has <code>getDescriptionId(ItemStack)</code> which can be overridden to provide different translation keys depending on <code>ItemStack</code> NBT.

By default, <code>getTranslationKey()</code> will return <code>block</code> or <code>item</code>. prepended to the registry name of the block or item, with the colon replaced by a dot. <code>BlockItem</code>s will take their corresponding Block's translation key by default. For example, an item with ID <code>examplemod:example_item</code> effectively requires the following line in a language file:

<code>format(String, Object...)</code> localizes in the client’s locale with formatting. The first parameter is a translation key, and the rest are formatting arguments for <code>String.format(String, Object...)</code>.

<code>TranslationTextComponent</code> is an <code>ITextComponent</code> that is localized and formatted lazily. It is very useful when sending messages to players because it will be automatically localized in their own locale.

<code>TranslatableContents</code> is a <code>ComponentContents</code> that is localized and formatted lazily. It is very useful when sending messages to players because it will be automatically localized in their own locale.

The first parameter of the <code>TranslationTextComponent(String, Object...)</code> constructor is a translation key, and the rest are used for formatting. The only supported format specifiers are <code>%s</code> and <code>%1$s</code>, <code>%2$s</code>, <code>%3$s</code> etc. Formatting arguments may be other <code>ITextComponent</code>s that will be inserted into the resulting formatted text with all their attributes preserved.
