Help with Pathfinding

Help and Feedback Scripting Support
1

So, I need help with updating a new path every second.

local RunService = game:GetService("RunService")
local PathfindingService = game:GetService("PathfindingService")

local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")

local waypointsFolder = workspace:WaitForChild("Waypoints") --Red parts

local function randomWaypoint()
	local waypoint = waypointsFolder:GetChildren()
	local random = waypoint[math.random(1, #waypoint)]
	return random
end

local function WalkTo(waypoint)
	local pathParams = {
		AgentHeight = character:GetExtentsSize().Y,
		AgentRadius = character:GetExtentsSize().X,
		AgentCanJump = false,
		Costs = {
			Danger = math.huge,
		}
	}
	
	local path = PathfindingService:CreatePath(pathParams)
	
	local success, errorMessage = pcall(function()
		path:ComputeAsync(character.PrimaryPart.Position, waypoint.Position)
	end)
	
	if success and path.Status == Enum.PathStatus.Success then
		for i,v in pairs(path:GetWaypoints()) do
			repeat
				humanoid:MoveTo(v.Position)
			until humanoid.MoveToFinished:Wait()
			randomWaypoint()
		end
	end
end

while task.wait(1) do
	local random = randomWaypoint()
	
	if random then
		WalkTo(random)
	end
end

You’re gonna have to use path.Blocked to detect when the path is blocked.

local RunService = game:GetService("RunService")
local PathfindingService = game:GetService("PathfindingService")

local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")

local waypointsFolder = workspace:WaitForChild("Waypoints")

local waypoints
local nextWaypointIndex
local reachedConnection
local blockedConnection

local function randomWaypoint()
	local waypoint = waypointsFolder:GetChildren()
	local random = waypoint[math.random(1, #waypoint)]
	return random
end

local function followPath(destination)
	local pathParams = {
		AgentHeight = character:GetExtentsSize().Y,
		AgentRadius = character:GetExtentsSize().X,
		AgentCanJump = false,
		Costs = {
			Danger = math.huge,
		}
	}

	local path = PathfindingService:CreatePath(pathParams)

	local success, errorMessage = pcall(function()
		path:ComputeAsync(character.PrimaryPart.Position, destination.Position)
	end)

	if success and path.Status == Enum.PathStatus.Success then
		waypoints = path:GetWaypoints()

		blockedConnection = path.Blocked:Connect(function(blockedWaypointIndex)
			if blockedWaypointIndex >= nextWaypointIndex then
				blockedConnection:Disconnect()
				followPath(destination)
			end
		end)

		if not reachedConnection then
			reachedConnection = humanoid.MoveToFinished:Connect(function(reached)
				if reached and nextWaypointIndex < #waypoints then
					nextWaypointIndex += 1
					humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
				else
					reachedConnection:Disconnect()
					blockedConnection:Disconnect()
				end
			end)
		end

		nextWaypointIndex = 2
		humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
	end
end

while task.wait() do
	local random = randomWaypoint()

	if random then
		followPath(random)
	end
end
