Tall AI won't go to player

I’m trying to make a new and better AI for my horror game, I am following this tutorial by gnomecode
for the AI.

It is a very tall wendigo but it’s unable to detect any players for that reason. Shown here:

No errors, here’s the script

local PathFindingService = game:GetService("PathfindingService")

local wendigo = script.Parent

local VISION_RANGE = 50
local ATTACK_RANGE = 15
local KILL_RANGE = 3.5

local target = nil
local distance = nil

local navigating = false

local destinationReached = nil

local function getRandomPath()
	local waypoints = workspace.WendigoWaypoints:GetChildren()
	local randomPoint = waypoints[math.random(#waypoints)]
	
	local path = PathFindingService:CreatePath({
		AgentRadius = 1.5,
		AgentHeight = 14,
		AgentCanJump = false,
		Costs = {
			NoWendigoAllowed = math.huge
		}
	})
	
	local success, errorMessage = pcall(function()
		path:ComputeAsync(wendigo.PrimaryPart.Position, randomPoint.Position)
	end)
	
	if success and path.Status == Enum.PathStatus.Success then
		return path:GetWaypoints()
	else
		local reverse = (wendigo.PrimaryPart.CFrame * CFrame.new(0, 0, 3)).Position
		
		wendigo.Humanoid:MoveTo(reverse)
		task.wait(0.1)
		return false
	end
end

local function EndNavigation()
	navigating = false
	
	if destinationReached then
		destinationReached:Disconnect()
	end
end

local function StartNavigation()
	navigating = true
	
	local waypoints = getRandomPath()
	if not waypoints then
		EndNavigation()
		return
	end
	
	local waypointIndex = 1
	
	destinationReached = wendigo.Humanoid.MoveToFinished:Connect(function(reached)
		if reached and waypointIndex < #waypoints then
			waypointIndex += 1
			wendigo.Humanoid:MoveTo(waypoints[waypointIndex].Position)
		else
			EndNavigation()
		end
	end)
	wendigo.Humanoid:MoveTo(waypoints[waypointIndex].Position)
end

local function getTarget()
	local maxDistance = VISION_RANGE
	local newTarget = nil
	
	for i, player in Players:GetPlayers() do
		local character = player.Character
		
		if not character then continue end
		
		local root = character:FindFirstChild("HumanoidRootPart")
		local humanoid = character:FindFirstChild("Humanoid")
		
		if not root or not humanoid or humanoid.Health <= 0 then continue end
		
		local origin = wendigo.HumanoidRootPart.Position
		local direction = root.Position - origin
		local distance = direction.Magnitude
		
		if distance > VISION_RANGE then continue end
		
		if distance > ATTACK_RANGE then
			local fov = direction.Unit:Dot(wendigo.Head.CFrame.LookVector)
			
			if fov < 0.5 then continue end
		end
		
		local result = workspace:Raycast(origin, direction * VISION_RANGE)
		
		if not result or not result.Instance then continue end
		
		if not result.Instance:FindFirstAncestor(character.Name) then continue end
		
		if distance < maxDistance then
			maxDistance = distance
			newTarget = character
		end
	end
	
	return newTarget, maxDistance
end

while true do
	target, distance = getTarget()
	
	wendigo.PrimaryPart:SetNetworkOwner(nil)
	
	navigating = false
	
	if target then
		EndNavigation()
		wendigo.Humanoid:MoveTo(target.PrimaryPart.Position)
		if distance < KILL_RANGE then
			target.Humanoid.Health = 0
		end
	elseif not navigating then
		--StartNavigation()
	end
	
	task.wait()
end

have you tried playing around with the “AgentHeight”? (lowering them)
Because I believe the trees are getting in the way. Either that, or you will have to upscale the trees.

#3

The agent params is for the random movement, and that is commented out until I can fix detecting players, it isn’t related to the player detection.

#4

Nvm I got it working! If anyone is experiencing the same issue make a part around the height a player is and make it where it’ll raycast from.
