Mobkit - Entity API [mobkit][alpha]

[Andrey01]

I`m making a head rotation API and I don`t know how to fix those horrible rotations represented on the video below (maybe pretty of low resolution, but I couldn`t do else):

Why does a head become to rotate in the spiral-like direction around the one`s torso and even being changed along 'y' axis if I change only the current rotation?

First guess, I'd check alignment of the head model. All rotations pivot around model's 0,0,0, so if the model is way up it would move like a hammer instead of rotating.
The zero point should be roughly around the bottom face of that cuboid.

Is it possible to make a mob stay put but still move and bite passing players?

Sure.
Actually such a behavior should be very simple, as it doesn't even involve moving around. Just turn towards the player, play an attack animation and punch if still in range.

I tried releasing eagles in a sparse forest, most of them managed to slalom between trees and gain altitude. Nicely done!

I've noticed while working on large hitbox support that mobs seem to have issues with snow. Just thought I'd tell you in case you didn't notice.

Hi
how could I check a mob not moving?
And not jumping? self.isonground?

not jumping: self.isongorund
not moving: check length of velocity vector

Yes, that's an artifact from 4.17 where nodes didn't have separate collision boxes. This bug is kinda fun and harmless so I don't feel hard pressed to fix it.

As to large box support, I am working on it, but in the meantime I got bored by working around various engine issues so now I'm trying to fix some of them and that will be the priority for some time. If I succeed it will make things better for everyone.

Is there a special reason why hq_goto target stops 3 nodes in front of target ?

Code: Select all

function mobkit.hq_goto(self,prty,tpos)
   [...]
         if vector.distance(pos,tpos) > 3 then
   [...]
   end
   mobkit.queue_high(self,func,prty)
end

Yes, engine bugs firstly :-)

Haven't found any use for that one. Iirc it's just a general area, also if you send more than one mob to the same spot they won't be fighting for the exact location.

It's a simple behavior, just copy it and modify as needed.

That's what I always do :)
Only, it took some time until I figured out why it was not working from the beginning, documentation says:

Code: Select all

function mobkit.hq_goto(self,prty,tpos)
   -- go to tpos position
   -- returns on arrival


I was wondering why my deers all starved. But they never reached their food, stopping 3 nodes in front of it XD

I've come across a problem, for some reason my mobs give me an error saying "lastvelocity" is nil at line 939 in mobkits init file. Any idea what would cause this?

The most common cause would be them not using mobkit.actfunc() in their on_activate callback.

Just got a request for those who want better mobs in Minetest and can be bothered to compile MT from source.

Please consider helping me test this PR: https://github.com/minetest/minetest/pull/9343

I have 5.1.1. Can I compile that?

[runs]

can 'mobkit.get_spawn_pos_abr' get a span pos into water?

[Termos]

Yes, besides a position it returns liquidflag which indicates if the node at pos is covered in liquid.
If it's false try to spawn a land creature, if it's true an aquatic one.

The PR is based on master which is currently 5.2. dev

[runs]

A user of my petz mod reported me that aquatic animals spawn so rarely, and in shallows. Can be caused by the player rarely face the oceans?

[Termos]

Technically yes, but then they have to get near water to be able to tell spawn rate is low, so I'd look elsewhere.

Try checking your spawn chances, and oh, the function only tells you if there's any water, so if you don't want them to spawn in shallows, you should check if it's deep enough.
