How do I make a pathfinder that detects the edges of the map / baseplate

[SanJoseYTXD (Spooky)]

Basically I want to make a pathfinder and put it to an npc, but this pathfinder can detect the edges of the map, to avoid falling, I already have the script done, what should I add to achieve this?

SCRIPT:

wait(0.1)
local pathFindingService = game:GetService("PathfindingService")

local path = pathFindingService:CreatePath()
path:ComputeAsync(workspace.testmy.HumanoidRootPart.Position, workspace.Goal.Position)
local waypoints = path:GetWaypoints()
for i, waypoint in pairs(waypoints) do
	if path.Status == Enum.PathStatus.Success then
		if waypoint.Action == Enum.PathWaypointAction.Jump then
			workspace.testmy.Humanoid.Jump = true
		end
		workspace.testmy.Humanoid:MoveTo(waypoint.Position)
		workspace.testmy.Humanoid.MoveToFinished:Wait()
	else
		print("failed path")
		break
	end
end

You could utilize the new pathfinding modifiers (BETA). Otherwise, you could always just add invisible barriers around your map, and PathfindingService would have to find a way to avoid those barriers (if possible).

New Pathfinding Modifiers - Studio Beta

Hello AI developers, Currently, PathfindingService almost always returns just the shortest path between the source and the target points. However, the optimal path should often consider the character/agent abilities, terrain type and game rules. For example - you may want an NPC to travel over a bridge instead of swim through water, cross a street in the crosswalk, or avoid an area that would damage the character. Introducing PathfindingModifiers PathfindingModifiers are instances used to an…

Thanks, but i am sure there is another form to archieve this

locsl part = workspace.Part
local partNegEndX = part.Position.X - part.Size.X/2
local partPosEndX = part.Position.X + part.Size.X/2
local partNegEndY = part.Position.Y - part.Size.Y/2
local partPosEndY = part.Position.Y + part.Size.Y/2
local partNegEndZ = part.Position.Z - part.Size.Z/2
local partPosEndZ = part.Position.Z + part.Size.Z/2

This would get you the the boundaries of each directional component for any part.
