Hello, I was really confused about the CheckOcclusionAsync, I check the wiki but there is no answer about using it. Can someone know how to use it? Here's the script that use in wiki but I modified it withCheckOcclusionAsync.

-- In Script in ServerScriptService
 
local pathfindingService = game:GetService("PathfindingService")
local pointModel = Instance.new("Model")
pointModel.Name = "Points"
pointModel.Parent = game.Workspace
 
-- Setup remote function
local remoteFunction = Instance.new("RemoteFunction")
remoteFunction.Parent = game.ReplicatedStorage
 
function visualizePath(path)
	-- clear old path visualization
	pointModel:ClearAllChildren()
 
	-- calculate new visualization	
	local points = path:GetPointCoordinates()
	for _, point in ipairs(points) do
		local part = Instance.new("Part")
		part.Parent = pointModel
		part.FormFactor = Enum.FormFactor.Custom
		part.Size = Vector3.new(1,1,1)
		part.Position = point
		part.Anchored = true
		part.CanCollide = false
	end
end
 
game.ReplicatedStorage.RemoteFunction.OnServerInvoke = function(player, target)
	local start = player.Character.Torso.Position
	local path = pathfindingService:ComputeSmoothPathAsync(start, target, 500)
	local checkPath = pathfindingService:CheckOcclusionAsync() -- This is the problem
 
	visualizePath(path)
	-- Check to see if the path was computed correctly
	if path.Status == Enum.PathStatus.FailStartNotEmpty or path.Status == Enum.PathStatus.FailFinishNotEmpty then
		print("Compute failed")
		return {}
	end
 
	return path:GetPointCoordinates()		
end

Thank You.
