PathfindingService
Show Deprecated
PathfindingService is used to find logical paths between two points, ensuring that characters can move between the points without running into walls or other obstacles. By default, the shortest path is calculated, but you can implement pathfinding modifiers to compute smarter paths across various materials, around defined regions, or through obstacles.
See Character Pathfinding for usage details.

Creating a Path with Pathfinding Service
local Workspace = game:GetService("Workspace")
local PathfindingService = game:GetService("PathfindingService")
-- This model contains a start, end and three paths between the player can walk on: Snow, Metal and LeafyGrass
local PathOptionsModel = script.Parent.PathOptions
local startPosition = PathOptionsModel.Start.Position
local finishPosition = PathOptionsModel.End.Position
-- Create a path that avoids Snow and Metal materials
-- This will ensure the path created avoids the Snow and Metal paths and guides
-- the user towards the LeafyGrass path
local path = PathfindingService:CreatePath({
AgentRadius = 3,
AgentHeight = 6,
AgentCanJump = false,
Costs = {
Snow = math.huge,
Metal = math.huge,
},
})
-- Compute the path
local success, errorMessage = pcall(function()
path:ComputeAsync(startPosition, finishPosition)
end)
-- Confirm the computation was successful
if success and path.Status == Enum.PathStatus.Success then
-- For each waypoint, create a part to visualize the path
for _, waypoint in path:GetWaypoints() do
local part = Instance.new("Part")
part.Position = waypoint.Position
part.Size = Vector3.new(0.5, 0.5, 0.5)
part.Color = Color3.new(1, 0, 1)
part.Anchored = true
part.CanCollide = false
part.Parent = Workspace
end
else
print(`Path unable to be computed, error: {errorMessage}`)
end
