Mobkit - Entity API [mobkit][alpha]
Re: Mobkit - Entity API [mobkit][wip]
Re: Mobkit - Entity API [mobkit][wip]
I've tested with my kitty mob:
-Kitty seems to avoid jumping heights, it can fall but it has to think about that.
-Kitty is not stuck on obstacles: cool!
-Kitty seems to spin too much.
-Kitty acts like a submarine in the water.
-I would like that kitty to follow me.

Re: Mobkit - Entity API [mobkit][wip]
Sounds like a good plan if you can manage to implement it. Most mods that want to do something with a (more intelligent) mob don't really have to know how to do all the small steps necessary to accomplish the larger goal. Duplication of code can be avoided, behaviour simulated. The builders I need for my citybuilder mod could profit.Termos wrote: Entity property (function). Mobs must have it, inanimate objects not necessarily so. This is where the most important cognitive processes take place: where do we come from, what is the purpose of meaning, and above all - what are we going to do next.
A list of my mods can be found here.

With this behavior active, they shouldn't fall down farther than they can jump back up. Would you tell me more about how it happened? What jump_height setting?
-Kitty seems to spin too much.
This is because there are no pauses between moves (intentional for demonstration purposes), so they go back and forth in rapid succession sometimes. You can try dropping a mobkit.lq_idle near the end in hq_roam.
-Kitty acts like a submarine in the water.
Buoyancy coming soon.
-I would like that kitty to follow me.
This is probably the next most important behavior, it's the very next on the todo list.
Re: Mobkit - Entity API [mobkit][wip]
Yup, this is the point, when this is more developed it should be easy to create different mobs quickly using a sizable library of built in behaviors.Sokomine wrote:Termos wrote: Most mods that want to do something with a (more intelligent) mob don't really have to know how to do all the small steps necessary to accomplish the larger goal.
These are humble beginnings, so there's only one atm, but more will follow.

Re: Mobkit - Entity API [mobkit][wip]
Springiness is not intended to be used with mobs, this is probably the cause, my guess is she bounces off the walls, try setting it to zero.
Also, I'd reduce the hitbox size 3 to 4 times to match the model, horizontal dimensions should never exceed 1 anyway.

The model size is inside a node. No hitbox, but collisionbox.Termos wrote:Springiness is not intended to be used with mobs, this is probably the cause, my guess is she bounces off the walls, try setting it to zero.

Re: Mobkit - Entity API [mobkit][wip]
Ok, the main reason is such a model alignment is not supported.
Probably it should be, as existing models' alignment seems to be all over the place, so now it is.
Tested with redo kitten model, mobkit reuploaded.
Thanks, good testin.
That box of yours is still way too big though, and there are no good reasons for horizontal dimensions not to be equal.

Re: Mobkit - Entity API [mobkit][wip]
I've tested it. Kitty is happy, now it can jump the hole :-D All is OK.
Re: Mobkit - Entity API [mobkit][wip]
Proper knockback.
Nothing fancy, giving it an initial velocity is enough.
That it stops when it should and then mobs continue their tasks is a byproduct of physics and behaviors.

Haha, he's a looker, ain't he?
True, his appearance may not be appealing to everyone's sensibilities,
so for the next clip i went with the Internet gold standard.
They can see me.
Now they are equipped with basic sensory apparata, it's time for more complex behaviors involving other entities and players, like following, running away, hunting, mating etc.

Re: Mobkit - Entity API [mobkit][wip]
I gotta feeling somebody's following me
The simplest follower brain which makes them follow the first player they encounter looks like this:
Simple enough, huh?
Alas, coding particular behavior functions is not as simple as I would like it to be, yet.

Re: Mobkit - Entity API [mobkit][wip]
Probably the coolest thing so far.
A mob attack that is defendable, makes combat more skill based and doesn't necessarily require animation
If I didn't dodge, it would have bit me.
They are inert during jump/charge, so there's time to react and predict where they're gonna land. It also scales up nicely - combat with one opponent is easy, but it goes downhill fast when outnumbered.
Of course it will be way cooler with a very short 'prepare to jump' animation.

Now that was an epic disaster, two months no backup ;) Luckily there's Ggl.
Reuploaded the latest preview package, see the first post.
Meanwhile, coming up next:
Buoyancy is relatively easy, but making them find closest dry land and come ashore is more tricky.

At this early stage repo would be impractical.Kurtzmusch wrote:why no git repo though?
I'm working alone - one hand testing and the other coding at the same time, so the code is constantly being modified locally.
I'm gonna Git it as soon as it makes sense.
Re: Mobkit - Entity API [mobkit][wip]
Quick update:
Uploaded the new version of wildlife, it features improved movement code, buoyancy and basic swimming, among other improvements.
Wildlife becomes it's own thing now, and likely it won't be getting many updates because next I'm moving on to working with third party animated models, as I don't have time for modelling and learning skeletal animation.
I'm also trying to submit it to contentDB, but approval is taking forever this time.
Edit: it's up on contentDB already: https://content.minetest.net/packages/Termos/wildlife/
