Pathfinding Compute async doesn't find any waypoints

I’ve been trying to make a client system using pathfinding but there has been times where the pathfinding doesn’t find a path when there’s clearly one, despite multiple attempts as seen in these pictures below.

code:

local initpos = Positions.Shop.Position+NumberUtility.DeserializeVector3(clientData.position)
	local finalpos = Positions.Shop.Position+GetDestinationBasedOnStep(clientData)
	local walkspeed = clientData.walkspeed
	local timeRequired = (finalpos-initpos).Magnitude/walkspeed
	
	local y = (Positions.Shop.Position.Y-Positions.Shop.Size.Y/2) + newModel:GetExtentsSize().Y/2
	
	if clientData.time/timeRequired>=1 then
		print("skipped ".. clientData.step)
		return
	end
	
	local pathfinding = PathfindingService:CreatePath({
		AgentRadius = 2,
		AgentHeight = 2,
		AgentCanJump = false,
		AgentCanClimb = false,
		WaypointSpacing = (finalpos-initpos).Magnitude/10,
		Costs = {
			Plastic = 0.01,
			Door = 0.01,
			DangerZone = math.huge,
		}
	})

	initpos = Vector3.new(initpos.X, y, initpos.Z)
	finalpos = Vector3.new(finalpos.X, y, finalpos.Z)

	pathfinding:ComputeAsync(initpos, finalpos)
	
	local waypoints = pathfinding:GetWaypoints()
	if not waypoints or not waypoints[1] then
		print("no waypoints for ".. clientData.step)
		return task.delay(.5, CreateNewBezier, clientData, newModel)
	end
	
	local params = RaycastParams.new()
	params.FilterType = Enum.RaycastFilterType.Include
	params.FilterDescendantsInstances = {workspace.Map}
	
	print("waypoint completed for ".. clientData.step)
	
	local points = {}
	local interval = #waypoints/20
	
	local raycast = workspace:Raycast(waypoints[1].Position, -Vector3.new(0, 100, 0), params)
	local groundDistance = raycast and raycast.Distance or 0
	local offset = Vector3.new(0, -groundDistance+newModel:GetExtentsSize().Y/2, 0)
	
	local startpos = waypoints[1].Position+offset
	table.insert(points, startpos)
	
	for index, v in (waypoints) do
				
		if index == 1 then
			continue
		end
		
		if index%interval == 0 and index ~= #waypoints then
			continue
		end
		
		table.insert(points, v.Position+offset)
		
	end
	
	ClientsBeziers[clientData.uid] = BezierCurve.new(table.unpack(points))
	return true

I would like to know what could result in this behavior and how to solve it in order to have a functional system.

Two suggestions:

  • Try using default parameters when you create the path object to see if that yields different results. If it’s able to compute a path, try adjusting your parameter values.

  • If that fails, turn on the ShowNavigationMesh setting under Studio settings. Go to Settings > Studio > Show Navigation Mesh. See if there’s any blockages in the blue traversal area that shows up.

Hope this helps
