How do I fix my pathfinding?

Help and Feedback Scripting Support
#1

Hey! My AI code for a monster in my game isn’t working well.

My AI keeps walking into trees or inclines and getting stuck for 10-15 seconds when it tries to follow me in sometimes. I want this fixed so it will just follow my player without getting stuck.

I tried to make the AI not follow you if you’re not moving, but it results in the strange effect of the mob not chasing you, and the issue still persists.

I do this on the client because the entire engine I use renders terrain on the client so server sided pathfinding would not work as the mob would just fall right through the floor.

Any help would be appreciated. Thanks!

This is my code.

local Char = script.Char

Char.Parent = workspace
Char.PrimaryPart.Anchored = false
Char.PrimaryPart.CFrame = game.Players.LocalPlayer.Character.PrimaryPart.CFrame

local PFS = game.PathfindingService

function get()
	local c
	local dist = 999999
	for _,i in pairs(game.Players:GetChildren()) do
		local char = i.Character
		if (char.PrimaryPart.Position - Char.PrimaryPart.Position).Magnitude < dist then
			c =  char
			dist = (char.PrimaryPart.Position - Char.PrimaryPart.Position).Magnitude
		end
	end
	return c
end

print("C")
repeat until get()
wait(1)
print("win")
local endpos = get().PrimaryPart.Position
local path = PFS:FindPathAsync(Char.PrimaryPart.Position,endpos)
local wps = path:getWaypoints()


function follow()
	endpos = get().PrimaryPart.Position
	if get().PrimaryPart.Velocity.Magnitude > 2 then
		path = PFS:FindPathAsync(Char.PrimaryPart.Position,endpos)
		if path.Status == Enum.PathStatus.Success then
			wps = path:getWaypoints()
			print("e")
		else
			print("x")
			return follow()
		end
		local Waypoints = {}

		for _,i in pairs(wps) do
			Waypoints[#Waypoints+1] =  {i.Position, i.Action}
			if _ > 50-1 then
				break
			end
		end

		--print(Waypoints)

		for _,i in pairs(Waypoints) do
			Char.Humanoid:MoveTo(i[1])
			if i[2].Name == "Jump" then
				Char.Humanoid.Jump = true
			end
			Char.Humanoid.MoveToFinished:Wait()
		end
		follow()
	else
		repeat wait() until get().PrimaryPart.Velocity.Magnitude > 2
		return follow()
	end
end

follow()

The script runs in the Workspace with the RunContext as Client.
