The emote mod adds an API and several commands to allow your character model to do new gestures!

The emotes implemented currently are:

/sit - sit down
/sleep - sleep as like in a bed
/lay - lay down, just like sleeping
/freeze - character stops moving as if frozen while walking
/point - raise hand out to signal a direction
/wave - do a quick hand wave
/stand - used to revert back from other emotes

Moreover, the API provides a way for other mods to use these interaction in their code.

The API is documented in the https://github.com/minetest-mods/emote/blob/master/README.md

Mods can use this API to make players able to sit on their nodes, sleep on custom beds or perform an emote like /point when interacting with a node (e.g. /wave when using a chest).

An example of how to make a player sit on a node is provided: https://github.com/minetest-mods/emote/blob/master/sit-on-stairs.patch

I love what you're doing here.

This is pretty cool. Now I can sit down and do nothing (not only in real life...) but in MT too! :D

(For some reason I was expecting to see facial expressions thinking emoticons :P ) which would also be cool

FYI the next item on the list is attachment to entities, so we can have a generic implementation allowing people to ride carts/boats with this code.

Would that be so they could ride animals too? By the way the kids are going to FLIPPPPPPP when they see this :) Thanks for making it!

Yes, the idea is that this API can be used by other mods to do attachment and pose. It will then be a lot easier for mods to implement vehicles since that code is already done, and they can just let this API do that work.

boats, carts, horses, pigs, helicopters, etc.

Hmm..., do you think you might be able to create a way for the player to grab onto something, while jumping up, and then letting go at a certain point by using this API?
The player could basically be attaching to the vine? (or does this sound dumb?)

If you get within interact range of a node that allows attachment using this API, then yes, you can "hang on" to a node that way. But releasing would make you just fall straight down.

Maybe there will be some way of using: pressing W while right click, to release and drop at an angle, or something once this API is finished?
It will be interesting to experiment with, I'm sure modders will exploit this new feature fully ; )

Can mods extend emote with new emotes?

No, if I do something like that then I'd make a callback hook for on release. The mod then can do any specific release behavior themselves.

Yes, but it does not make any sense. Any emote has to come from the existing player character animations, so if you can find a new one, I'll add it to this mod immediately.

If we want to radically add new player animations (/dance) someone will have to make these player animations in blender. Possible, but that would make the character model non-standard, and result in other issues with other mods.

Sofar is it possible to "inject" animation files that were created in Blender? I know this is possible in other games. I wish I knew what keywords to search for to learn more about it. I remember during the brief time of playing Second Life, simple and sometime very sophisticated animations could be played with the players character model.
With the acceptation of moving bones via lua, our player models animations are hard coded within them. I've wondered about this for a while.
Hopefully I'm making sense as I've only been awake for like 5 minutes :)

Head movement would be nice. So you have a visual yes and no:

/nod
/shake

Fairly sure it would require an engine change, and a protocol change as well in minetest in order to do that.

Yes, but that would require:

1) bone manipulation
2) synchronization over time to make the head movement correct if the player moves around while doing this emote

So, way too complex for now, sorry.

This happened with `/stand`. I've pushed a fix to the repository to fix, please try that and let me know if there are additional problems!

Thank you so much and sorry I couldn't post more info, I have a class of 18 kids so things have to be done quickly haha. We are using the latest version of minetest, but not the newest dev if that helps at all. We'll be sure to test tomorrow and thanks again!

As a note we were mostly having the crash when we were trying /wave

Posted: **Tue Jan 10, 2017 18:41**

Great, very great!!!
But can you make some more emotes (like cry; be angry; clap hands; fasepalm; make a somersault)?
:)

I do notice... and I am just as guilty as others here, of it...
and I'm just pointing this out as a "hehe" sort of thing... just poking fun at our human nature... :P

so, someone does a bunch of work to introduce a wicked cool new feature..., and we all say "cool"... "can you make it better?" :P

just something I noticed for a while here..., and in life in general :D

Not without doing animation work and breaking tons of mods that rely on the character model that we have right now.

Maybe later?

That's why I made it. First to explore how far we can take it (how many emotes can we already make with the default animations we have?), but also how can we make mods use these easily.

One of the things I'd like to do is attach these animations to e.g. the furnace, chests, and doors, so that when players use these nodes by right clicking them, an animation is shown - instead of a player just standing still.

That's why it's an API as well - so more nodes can then use the ideas in this mod easily, and the whole game is uplifted another level of refinement.

Funny you mention some of these things... I'm working on animated chests... and some other things.
Yep, some bling, or visual-brain-candy, is definitely needed

Seems to not be crashing since your update, thanks!! The point worked but I didn't see my character waving. I'll have to test more. Great job on this!

Posted: **Sat Jan 28, 2017 20:10**

This mod doesn't work with playeranim. Perhaps Rui can help with a merge patch?

Posted: **Sat Jan 28, 2017 20:53**

I was going to try to see if there is a way to write a script to do a series of the commands so that you can set up dancing and especially "break dances" haha.

Posted: **Wed Feb 15, 2017 01:25**

This has great potential! First thing I'd want to do if I knew how would be to have players sit down whenever they're using the crafting formspec.

The problem is that the interfaced used by playeranim are minetest_game player.lua API's ... and they're terrible.

Plus head animation should be a client-side modding thing, not server-side. So I actually don't even want to spend time on that right now.
