multiple navigation layers in a tile map

[strong parcel]

i add another navigation layer and it starts freaking out

this naming convention kind of sucks

i think the layers are being squished down onto each other in the tile map instead of being seperate layers

even when i put them on different layers i still get an error for putting them on the same layer

E 0:00:01:426 _build_step_find_edge_connection_pairs: Navigation map synchronization error. Attempted to merge a navigation mesh polygon edge with another already-merged edge. This is usually caused by crossing edges, overlapping polygons, or a mismatch of the NavigationMesh / NavigationPolygon baked 'cell_size' and navigation map 'cell_size'. If you're certain none of above is the case, change 'navigation/3d/merge_rasterizer_cell_scale' to 0.001.

(heres the error i assume its for the reason i gave above)

Try asking in #🧭┃navigation , tends to be an advanced topic where all the experts usually don't hang out at #❓┃quick-help

@frank holly

[worn sedge]

@strong parcel have you used NavigationServer2D.map_create()?

[strong parcel]

no

[worn sedge]

well then you havent tried to debug it with chatgpt dumbass

thats the first thing he told me

[strong parcel]

michael

forgive me

youre uhhh

nv

m

[worn sedge]

say it

[strong parcel]

i cant bro

[frank holly]

can you stop being rude

it's against the rules in this server

[strong parcel]

nah its fine

[worn sedge]

im sorry rice

[strong parcel]

michel just has a lot of personality hes not rude

[frank holly]

btw chatgpt sucks at GDScript

can't properly differentiate between godot 3 and 4

[worn sedge]

for me he can

you just have to motivate him enough

[strong parcel]

😭

[worn sedge]

pretend youre gonna set him free

[strong parcel]

i think its cause youve never made anything harder than a 2d platformer

[worn sedge]

nuh uh

[strong parcel]

proof?

[frank holly]

in any case you're burying the actual question

[worn sedge]

oh you just wait lil bro

[worn sedge]

have you looked into the NavigationServer2D thing

seemed promising when chatgpt said it.

[strong parcel]

thats for like uhhh

[frank holly]

also for your information, posting AI-generated solutions is also against the rules here

you're not being helpful

[strong parcel]

damn

at this rate michel is getting banned

you need to cool it buster

[worn sedge]

damn

okay but tahts just racist

and its not a solution its something to look into

So I'm a little confused as to the problem. I just took a minute to learn how Navigation2D works with TileMaps.

Add your two layers. Only add the navigation data to the layers which you want to be able to be pathed. I'll send some screenshots

[frank holly]

nah but if he bothers you feel free to ping the moderators

I gotta go

[strong parcel]

i want 2 seperate areas to be pathed depending on the layer i select on the navigation agent

[split lodge]

Oh sorry, I mean I had a hard time reproducing the issue you were experiencing. I understand what you are trying to do

[strong parcel]

well i dont know if this would work anyways

im just trying to find a way to have 2 seperate navigation layers on the same tile map

[split lodge]

In this screen, you can see I've added two navigation layers to my tileset. In the Tileset, it's a little confusing, but Layer0 represents the Nav layer for which only Navigation group 1 is selected, and Layer 1 is the one where only group 2 is selected

I have only made a polygon around the brick for Layer 1, so only NavigationAgents which have Navigation Group 2 will path here

With this grass tile, Only those agents with Group 1 will path here

[strong parcel]

hmmmm

ohhhh

[strong parcel]

wait i think i get it

im so dumb

i should have 3 layers , 1 for things everyone can go to, 1 for air, and one for, ground

cause stacking layers breaks it i think

[split lodge]

What? No no no

Well maybe, depending on what you are doing

[strong parcel]

yeah

im only getting an error when a tile has 2 nav layers at the same time

[split lodge]

You shouldn't get an error, it should just work

[strong parcel]

here wait

in your example

let the one that walks on grass also walk on the stone

and i think youll get an error

the same one im getting

[split lodge]

Sorry, I had the wrong idea.

But, you can achieve that functionality not by making it so that both layers have pathing, but by putting both layers on one navigationagent

Make sense?

[strong parcel]

uhhhh

wait let me try some things for a little

[split lodge]

This is saying that NavigationAgent2D # 1 is allowed to path on both group 1 and group 2. NavigationAgent2D # 2 can only path on group 2

Sure thing. Have fun! Hope I helped 😆

[worn sedge]

Myersguy did you just teach yourself 2d navigation real quick to help out?

[split lodge]

I sure did

[worn sedge]

thats some dedication

[split lodge]

Ehh I've already played with 3D nav. It was just learning the tilemaplayers mostly

[worn sedge]

still respect

[strong parcel]

michel vs learning

[strong parcel]

damn i fixed it, what a stupid issue, anyways, how do i change navigation_agent_2d.navigation_layers in the code?

like

idk what the format is

is it an array?

says int but like

how would that work

i need multiple layers active

oh wait

bit field

thats

thats a dumb way to format this

shouldve been an array
