====== Adding a tooltip ======
In your [[tutorial:items|item]] class, override ''<yarn method_7851>'' like so (see [[tutorial:lang]] for how to translate the tooltip).

For versions 1.18.2 and before:
<yarncode java>
@Override
public void method_7851(class_1799 itemStack, class_1937 world, List<class_2561> tooltip, class_1836 tooltipContext) {

    // default white text
    tooltip.add(new TranslatableText("item.tutorial.custom_item.tooltip"));

    // formatted red text
    tooltip.add(new TranslatableText("item.tutorial.custom_item.tooltip").method_27692(class_124.field_1061));
}
</yarncode>

For versions since 1.19:
<yarncode java>
@Override
public void method_7851(class_1799 itemStack, class_1937 world, List<class_2561> tooltip, class_1836 tooltipContext) {
    tooltip.add(Text.translatable("item.tutorial.custom_item.tooltip"));
}
</yarncode>

For versions since 1.20.5:
<yarncode java>
@Override
public void method_7851(class_1799 itemStack, TooltipContext context, List<class_2561> tooltip, TooltipType type) {
    tooltip.add(Text.translatable("item.tutorial.custom_item.tooltip"));
}
</yarncode>

You can also append your tooltip in the [[tutorial:blocks|block]] class by overriding a similar method:

For versions below 1.20.5:
<yarncode java>
@Override
public void method_9568(class_1799 itemStack, class_1922 world, List<class_2561> tooltip, class_1836 tooltipContext) {
    // for versions 1.18.2 and before
    tooltip.add(new TranslatableText("block.tutorial.custom_block.tooltip"));
    
    // for versions since 1.19
    tooltip.add(Text.translatable("block.tutorial.custom_block.tooltip"));
}
</yarncode>

For versions since 1.20.5:
<yarncode java>
@Override
public void method_9568(class_1799 itemStack, Item.TooltipContext context, List<class_2561> tooltip, TooltipType options) {
    tooltip.add(Text.translatable("block.tutorial.custom_block.tooltip"));
}
</yarncode>
