Feature - Emotes API

[ItsNature]

Overview

Description:
Adds NPC emote support to the Cosmetic module, allowing servers to play, stop, and reset emotes on NPC entities. Also adds a copyLocalCosmetics option to the NPC equip flow so an NPC can mirror each recipient's own equipped
cosmetics.

Changes:

• New Emote builder (id & metadata).
• New CosmeticModule API:
  • startNpcEmote(Recipients, UUID, Emote)
  • stopNpcEmote(Recipients, UUID)
  • resetNpcEmotes(Recipients)
  • equipNpcCosmetics(Recipients, UUID, List<Cosmetic>, boolean copyLocalCosmetics)

Code Example:
Equip cosmetics on an NPC, copying the recipient's own cosmetics

public void equipNpcCosmeticsCopyLocalExample(UUID npcUuid) {
    this.cosmeticModule.equipNpcCosmetics(Recipients.ofEveryone(), npcUuid, new ArrayList<>(), true);
}

Start an emote on an NPC

public void startNpcEmoteExample(UUID npcUuid) {
    Emote emote = Emote.builder()
        .id(56)
        .build();

    this.cosmeticModule.startNpcEmote(Recipients.ofEveryone(), npcUuid, emote);
}
