[API]Open AI [open_ai]

by jordan4ibanez » Tue Dec 13, 2016 08:16

Open AI

An API which makes mob creation easy and fast. Mobs made with this API are aesthetically pleasing, fast, low on resources, and include all the things you'd expect out of a mob in the game (In the release).

Right now I am working hard to get all the code working to the best of my abilities to get mobs which add to the game but do not hog resources.

Mob entities will use their own internal functions to be as quick as possible and to be modular.

Goals:
  • Utility mobs which can regrow whatever the harvestable item is
  • Drowning
  • flying
  • Mobs avoid walking into other mobs and players
  • Hostile mobs attack players
  • Hostile by day, or hostile by night mobs
  • Avoid sunlight or darkness and seek shelter if available
  • Climb ladders and bounce on bouncy nodes
  • Equip armor and an item if using player mesh along with armor mod
  • Use line of sight to get player or entity positions when following, if a player gets out of line of sight, the last position that the mob saw you or the other mob, it will go to
  • Mob sound effects
  • Death animations
  • Particles
  • Remembering players that attacked/fed them and adjusting accordingly
  • Learning what nodes hurt/help them

Information about this mod can be found on the github wiki

I hope to have a complete mob AI sometime by June. There are also no version numbers, this is rolling release.

3 other goals to add:
remeber to avoid objects / nodes that have damaged it
hide while low health / are peaceful
temper, get more agresive if something hurted it, or less after eating/more health

Some extra facts:
some believe that AI only is thinking / smart bots, but the word means "artificial intelligence" they not only thinking, they also teaches himself / remember.
And some modify its source code.

Erk! That last point may be tricky when the minetest sheep becomes the next skynet :P

but the sheep could remember which player was nice to it and who was mean
or it gets better skills that help at running away from evil players wanting to kill the sheep, eg. on birth they collide on jumping often with wall and its easier for the murderous player to kill it
Do not call me -minetest.
Call me DS or DS-minetest.
I am German, so you don't have to pm me English if you are also German.
The background is a lie.

That's a good idea. Not only should they learn when players are mean to them, but they should learn what nodes hurt/feed them

looks pretty cool! tenplus1's mobs-redo is pretty awesome already, but i'll be keeping my eye on yours too!

My request: add some sort of api to allow other mods to pass their own rewards (like experience points) or to execute custom functions (like upon death, or tame, or whatever) into your mobs.

i tried before, but got borred, but now I could not refrain: create AI NPC/mobs
(reason: found minetest.find_path)

I have been working on it for 3 days, and there are one kind of npc, that can search & mine trees, search for a suitable space and build a house (the house corrently always fails)

i need to make it remember where to find resurse (currently only trees, (kinda done))
remmber where it lives
and make the building not fail :-) + some extra small things
then i will upload it as a very wip / test mod.

Here's an update video showing the slightly improved path finding implication and basic magnetic "soft" collision detection.
https://youtu.be/PDrIm3LKmDg

Updates:
  • Mobs will now only jump when the pathfinding goal is higher then they are
  • A mob will stop moving when the pathfinding goal is less than 2 points
  • Mobs use a magnetic "soft" collision detection so there can be a lot of them in an area without them getting stuck on eachother

Thank you for the idea, this has been implemented with no limitations

Users can define custom functions that normal entities use, plus the on_die function for when a mob dies

I'll be following this carefully as it seems super interesting and I find AI interesting in general. One thing I'd be personally interested in is NPCs that are easy to add and have them say something when you approach or right click them. Eventually I'd love to see a mod like Millenaire in Minetest but I know that is asking a lot. This is fantastic work and I loved the vid of the sheep following you. I think my students would absolutely love it if their animals/pets could follow them because I don't think they do in mobs redo unless I'm missing something.

Also side question, in your video I saw you had some bamboo trees. What mod are those from? They look quite interesting.

Thanks and take care!

WHY?

by Wuzzy » Mon Dec 19, 2016 19:20

This mod leaves one fundamental question open: Why? Why another mobs mod?

Sorry, but this is like the gazillionth mobs mod. The Minetest community really suffers from a serious case of Not Invented Here when it comes to mobs.

The feature list does not impress me, nor the list of planned features. It does not stand out from the rest, most other mob mods already have these. I am sure you worked hard on this mod already, and I appreciate that, of course. But basically you seem to implement (mostly) what other mods already have. It doesn't seem to be a smart use of your time.
The few new planned features which are actually unique would probably be better off in one of the existing mods. Why not just contributing to one of those?

But you may convince me otherwise. Is there anything in this mod or in your plans which requires an entirely new mod? Or do you use a general design concept which is fundamentally different from the existing mods?
Otherwise, I feel your mod will ultimately just be 90% redundant to mods which already exist, are already implemented, work fine and have been tested.

Don't get me wrong: I am generally in favor for more mobs and for more mob features. But I also feel the community is already very fragmented when it comes to mobs, and it only gets worse. It is not good to have various mob features scattered around in many small incompatible mods.
I am also not against more mobs mods, as long they actually make sense and follow a principle not already implemented by other mods. But I do not like the proliferation of mods only for the mod's sake.

Do you have a particular reason why you chose to start from scratch rather than to use one of the existing mods? E.g. have the existing mods problems which seem unsolvable?

Don't get discouraged by my words either: You are of course still free to do whatever you want and you can ignore everything I say. :D I am just not sure if it is really a good use of your time to start completely from scratch (which you apparently do) if your goal is to make mobs easier. But maybe you have a legit reason, I don't know.

Long story short: My goal is not neccessarily to shut your mod down or something like that, my goal is to make you think about your goals.
I'm creating MineClone 2, a Minecraft clone for Minetest. I made the Help modpack, adding in-game help to Minetest.

Already the code is much simpler than all the others, which is a nice thing.

To be the definitive mobs mod of minetest, aesthetically pleasing while adding elements to the game that haven't been thought of or implemented yet while not taxing the hardware. Code readibility and simplicity is also a goal which will be implemented some time in the future.

For new Mobs since you have them already following you in your newest video, what about pets? Dogs, maybe cats, frogs (not realistic but fun), horses, dragons, etc. Maybe even an NPC/travel guide/travel companion. Just ideas :)

Just to ask again in case you missed my post, what mod were those bamboo trees in from your carts videos and other videos?

Take care!

I have watched your videos on follower pathing and it looks very nice so far, I must say! I don't think there is anything wrong with making another mobs AI. I was about to make some comment like that ("Why yet another mob AI, why not work on an existing?), but then I thought, AI is super complex and any working approach that one is will to share with the rest of us should be appreciated. It's easy to call out "duplicated effort" but really, no one has "solved the problem" for everyone (if such a thing is even possible) so if you have a new way that works for you, where others do not, that's all the reason you need!

Hey thanks man. Yeah I'm trying my hardest to do everything a mob should do!

Thanks for the heads up on the Ethereal mod! I love the video of the mobs riding in the minecart, that's priceless!

Also thanks for all of your code comments. I'm going to have my students check out your mod and look at the code to get an idea about how the AI code works. I think it'd be interesting to have them (and me) compare and contrast your code vs mobs redo just to see how things are achieved.

Thanks for all your hard work! I love watching the development.

It's good to know that this mod is being used for learning, thank you.

I checked the videos and i'm really amazed at how those mobs are moving, they nearly "feel" alive.
Can't wait to see how it will go.
