Pathfinding is creating a path with a bunch of waypoints close to each other in a line

Hi!

I’ve been developing an AI but ran into a little issue with pathfinding waypoints.

It looks like PathfindingService is generating a path with a bunch of tightly packed waypoints in a line (hold note lookin’)

I’ve tried looking for other posts like this but couldn’t find anyone with this issue.
My code has also set WaypointSpacing to 8, which does work, but still these “hold note” paths are made

Does anyone know what could cause this?

(Here’s the path that it uses for context)

local PathfindingService = game:GetService("PathfindingService")
local path = PathfindingService:CreatePath({
	AgentRadius = 5,
	AgentHeight = 5,
	AgentCanJump = false,
	WaypointSpacing = 8,
	Costs = {
		Water = 20,
		Mud = 2,
		Grass = 2,
		ForestGrass = 2,
		Ground = 2,
		LeafyGrass2= 2,
		Snow = 2,
		Sand = 2,
	}
})

The AI individually walks to each one and stutters over it so I’d like those to not happen!

path:ComputeAsync(start, end)

local points = path:GetWaypoints()

for i = 1, #points do
local point = points[i]
print(point.Position)
end

Output:

Hi! Thanks for the reply, but how does this apply to my question?

I’m not sure how this is helpful to my situtation.

I understand how to create a path, interate over the waypoints, etc.

I’m having the same issue. Did you find any solution to it?

bro…

just loop through the waypoints table and verify that each waypoint is waypointSpacing distance away from each other - if its not, remove it

this is a bad “solution” as it can comprimise the usefulness of the path in certain cases e.g imagine if there is a tight bunch of waypoints all the way around a corner deleting all but one of them will stop them being close yes but means the humanoid trys to walk through an obstacle

additionally it introduces extra overhead to a pricey built in feature that should be well managed in the first place to not do this
