How to allow NPC to know height in pathfinding

Help and Feedback Scripting Support
#1

Hi, I am currently re-working on my game and I am struggling with pathfinding for enemies. For some reason, those dummies won’t create waypoints if there are height differences between them and the player (e.g., they are on a 2-stud height part; they could just let themselves fall but they don’t want to).

Here is the script, please help:

local PathfindingService = game:GetService(“PathfindingService”)

local NPC = script.Parent.Parent
local coreFold = NPC.CoreFolder
local humanoid = NPC:WaitForChild(“Humanoid”)
local humRP = NPC:WaitForChild(“HumanoidRootPart”)

local MAX_RETRIES = 5
local RETRY_COOLDOWN = .001

local path = PathfindingService:CreatePath()
local reachedConnection

local CombatState = false
local CombatStateDistance = 20

local randomWalkDuration = 1 – Durée en secondes de la marche aléatoire
local maxRandomWalkDistance = 40 – Distance maximale à parcourir pendant la marche aléatoire

– Fonction pour obtenir la cible Humanoid la plus proche
local function getClosestHumanoid()
local closestHumanoid
local closestDistance = 150

-- Parcourez tous les objets dans l'environnement
for _, entity in ipairs(workspace:GetChildren()) do
	-- Vérifiez s'il s'agit d'un Humanoid et s'il n'est pas le parent lui-même
	if entity:IsA("Model") and entity:FindFirstChild("Humanoid") and entity:FindFirstChild("Humanoid").Health > 0 and entity ~= NPC then
		
		local function ClosingUp()
			local distance = (entity:FindFirstChild("HumanoidRootPart").Position - humRP.Position).Magnitude
			if distance < closestDistance then
				closestHumanoid = entity:FindFirstChild("Humanoid")
				closestDistance = distance
				if distance < CombatStateDistance then
					CombatState = true
				else
					CombatState = false
				end
			end
		end
		if entity:FindFirstChild("Team") then
			if entity.Team.Value ~= NPC.Team.Value then
				ClosingUp()
			end
		else
			ClosingUp()
		end
		
	end
end

return closestHumanoid

end

local function walkTo(targetPosition, yieldable)
local RETRY_NUM = 0
local success, errorMessage

repeat
	RETRY_NUM += 1 -- ajoutez un essai
	success, errorMessage = pcall(path.ComputeAsync, path, humRP.Position, targetPosition)
	if not success then -- si cela échoue, avertissez le message
		warn("Pathfind compute path error: "..errorMessage)
		task.wait(RETRY_COOLDOWN)
	end
until success == true or RETRY_NUM > MAX_RETRIES

if success then -- si le calcul du chemin ne pose pas de problème
	if path.Status == Enum.PathStatus.Success then
		local waypoints = path:GetWaypoints()
		local currentWaypointIndex = 2 -- pas 1, car 1 est le waypoint de la position de départ.
		
		if waypoints[currentWaypointIndex].Position.Y > humRP.Position.Y + humanoid.HipHeight then
			-- Il y a un obstacle en hauteur, le NPC doit sauter ou se laisser tomber
			humanoid:Move(Vector3.new(0, waypoints[currentWaypointIndex].Position.Y - humRP.Position.Y, 0))
		else
			humanoid:MoveTo(waypoints[currentWaypointIndex].Position) -- déplacez-vous vers le nième waypoint
		end

		if waypoints[currentWaypointIndex].Action == Enum.PathWaypointAction.Jump then
			humanoid.Jump = true -- si cela nécessite un saut
		end

	else -- si le chemin ne peut pas être calculé entre deux points, ne faites rien !
		return 
	end
else -- si la chance de réessayer est maximale
	warn("Pathfind compute retry maxed out, error: "..errorMessage)
	return
end

end

local function updateRotationToTarget(targetPosition)
local lookAtPosition = Vector3.new(targetPosition.X, humRP.Position.Y, targetPosition.Z) – Assurez-vous de garder la même hauteur (axe Y)
local newRotation = CFrame.new(humRP.Position, lookAtPosition)
NPC:SetPrimaryPartCFrame(newRotation) – Mettez à jour la rotation pour regarder la cible
end

local function performRandomWalk(targetPosition)
local randomWalkDirection = Vector3.new(math.random(-1, 1), 0, math.random(-1, 1)).unit
local randomWalkDistance = math.random(0, maxRandomWalkDistance)
local randomWalkStartPosition = humRP.Position

local randomWalkEndTime = tick() + randomWalkDuration

while tick() < randomWalkEndTime do
	local currentWalkPosition = randomWalkStartPosition + randomWalkDirection * randomWalkDistance * (tick() - randomWalkEndTime + randomWalkDuration) / randomWalkDuration
	updateRotationToTarget(targetPosition) -- Mettez à jour la rotation pour regarder la cible
	walkTo(currentWalkPosition, true)
	wait() -- Attendez un peu entre chaque mise à jour de la position
end

end

spawn(function()
while wait() do
local targetHumanoid = getClosestHumanoid()
if targetHumanoid then
local targetPosition = targetHumanoid.Parent:FindFirstChild(“HumanoidRootPart”).Position
if CombatState then
local randomFactor = math.random(0, 10)
if randomFactor <= 1 then
performRandomWalk(targetPosition)

			else
				
				walkTo(targetPosition, true)
			end
		else
			updateRotationToTarget(targetPosition) -- Mettez à jour la rotation pour regarder la cible
			walkTo(targetPosition, true)
		end
	end
end

end)

Don’t mind the quote on the script i am french, and sorry the script wasn’t totally wrote has a script. Forum’s fault not mine
