NavMesh baking

[hexed sorrel]

How do i bake a navmesh with dots/physics shapes?

[thick sandal]

that's a pretty broad question 😄

do you mean like, unitys built in navmesh i guess?

do you need bake it at runtime (dynamic world)

or is baking it in editor fine?

[hexed sorrel]

baking in editor

but i only have physica shapes not the mb colliders

[thick sandal]

unity's navmesh baking can use meshrenderers (by default if I recall correctly)

[hexed sorrel]

but i have only physics shapes. is it possible?

It is for a game server without renderers

[hexed sorrel]

I can write a code to convert physics shape to colliders, bake on code then convert bake

does it makes sense?

[deft grove]

you dont have to create colliders from shapes. you can create navmeshbuildsources from PhysicsShapes

[hexed sorrel]

from code?

and use NavMeshBuilder

i wrote a post how to do this like 3.5 years ago
https://forum.unity.com/threads/navmeshsurface-updatenavmesh-with-a-entity.766148/#post-5110340

i don't use unity navmesh anymore but it should be somewhat of a decent place to start

Wow. Are u working on full pure dots navigation solution?

[thick sandal]

yeah i've had one for ages

i've shown it off multiple times. even have it streaming over network in netcode

[hexed sorrel]

Why don`t you use NavMesh?

Is it grid based?

[thick sandal]

i do use navmesh

i just have my own implementation

[hexed sorrel]

Why not unity navmesh?>

[thick sandal]

it doesn't do what i want (i can't get data out)

[hexed sorrel]

I see

[thick sandal]

and i just have a lot more control

and a lot more settings

[hexed sorrel]

Is your navmesh grid based or triangle based?

[thick sandal]

its the same backend that unity uses

[hexed sorrel]

recast?

[thick sandal]

yes

i just have my own wrapper for jobs

and i'm slowly porting chunks at a time to burst

my (variation of) detour is mostly done

i barely rely on any native code for that

[hexed sorrel]

I see

This looks cool and a lot of work

i plan to use https://www.youtube.com/watch?v=6BrZryMz-ac&t=279s

[thick sandal]

its been a huge amount of work

[hexed sorrel]

contextual steering behaviours

for local avoidance

[thick sandal]

i have a full implementation of ORCA

it handles like 250,000 units

[hexed sorrel]

what is ORCA?

[thick sandal]

https://gamma.cs.unc.edu/ORCA/

(commonly called RVO2 after the original RVO)

[hexed sorrel]

You need to work for unity

to speedup dots 😅

[thick sandal]

from start of last year

it's improved a lot since then

and i've integrated it with my navmesh now

so the VOs have awareness of the edge of world

(this was primary reason i rolled my own navmesh)

[hexed sorrel]

what is the hardware for this test?

[thick sandal]

3900X

so a pretty ok cpu

1060gtx though

i am much more gpu capped

[hexed sorrel]

yeah, but a better server than this is not expensive

[thick sandal]

its barely taking anytime to process this

[hexed sorrel]

i`m more interested in high performance server than client

Are you using rival C.C?

[thick sandal]

no

i don't use any third party libraries

this is my navmesh (it's zoomed out so a lot of LOD has kicked in to hide stuff)

and this is the data i really wanted

proper windings on edges

so i can pass all these lines into my avoidance simulation

so it doesn't 'avoid' out of bounds

pretty sweet

recorded this earlier today )video quality is really shit was trying to keep it small for a non-upgraded server) but i just spent 4 days rewriting how agents query and follow paths

[hexed sorrel]

Why does your navmesh looks square?

[thick sandal]

the coloured boxes?

[hexed sorrel]

Your game looks cool

yeah

[thick sandal]

those are each individual tile in the navmesh

[hexed sorrel]

I see

[thick sandal]

this way if i make a change i only need to update that tile

[hexed sorrel]

even at runtime?

[thick sandal]

yes

this is only generated at runtime

i haven't bothered with any pre-baked implementation

[hexed sorrel]

I see

Your game looks like mine

Is it like v-rising too?

[thick sandal]

none of this is really a game

i mostly just work on libraries

(and ive been working on this stuff long before v-rising was announced =D)

[hexed sorrel]

Nice, this looks super cool

[thick sandal]

cant take any credit for the graphics

just an asset store scene i liked the look of and thought would be good for testing

[night badge]

👀 I want ur full dots navigation solution. Sadly looks like official dun have plan to implement it yet

[hexed sorrel]

I use the same asset lol

[hexed sorrel]

don`t unity navmesh works with dots?

[thick sandal]

you can use them via that experimental api

[hexed sorrel]

there is experimental API, but it does not have the same features as tertle one

[thick sandal]

it just takes a bit of manipulation

[night badge]

Yes but in future if I want to build pure dots server maybe it's not possible 🥲

[hexed sorrel]

i`m building pure dots server. What do you mean?

[night badge]

Meaning it's completely pure dots server that dun have any unity engine api dependency

[hexed sorrel]

Ok, i see

the tiny project?

[night badge]

Ya. Initially official doing this for project tiny. Not sure when they will continue the development again

[hexed sorrel]

@thick sandal which grass texture do you use here
