Minecraft Default Wave Emote, this add-on adds the “say hello” animation in Minecraft PE 220.127.116.11+. Although in reality it seems that the character is dancing. This is available exclusively for Minecraft 1.13. To activate it press the button to bend down and you will automatically use the emote.
This add-on adds a really fun emote to the game which you can enable simply by sneaking. Custom animations is now available for the player model, and emotes is a great use case for it!
