I want to check if the source of the player's attack is a Skeleton，But I can't find the corresponding API

Because I want to design a set of armor，When wearing, receiving bow and arrow damage will automatically generate an arrow in the backpack

因为我想设计一套盔甲，当穿戴时，受到弓箭伤害会自动在背包中生成一支箭
因为我想设计一套盔甲，

May I ask what I should do?

Assuming 1.20.1, you can subscribe to the LivingDamageEvent and get the DamageSource from there:

@SubscribeEvent
public static void onDamage(final LivingDamageEvent event) {
    final DamageSource source = event.getSource();
}

With the DamageSource you can then check if it's caused by an arrow. Probably by source.type() and checking if it matches DamageTypes.ARROW
