Ray not working correctly

Help and Feedback Scripting Support
1

I have a script that controls multiple NPCs and it works for the most part, but I have a problem with the Raycasting. The function where the Raycast is done runs when a tag is added in CollectionService which tells a spawned NPC to move to the Raycast instance. The problem is that the Raycast doesn’t work for some of the NPCs that spawn, but it works for most of them. I also have another problem in the same function. The NPCs goal is to destroy a wall and if a section of the wall is destroyed they are all supposed to move to a position behind the wall. The problem with this is that some of them react when the wall is destroyed, but most of them do not move at all.

Here is the function I have a problem with:

RayCast function 
function attackPosition(obj)
	local params = RaycastParams.new()
	params.FilterType = Enum.RaycastFilterType.Blacklist
	params.FilterDescendantsInstances = {workspace.CloneFolder, workspace.Baseplate}
	params.IgnoreWater = true
	
	local rayResult = workspace:Raycast(obj.HumanoidRootPart.Position, (obj.HumanoidRootPart.CFrame.LookVector).Unit*600, params)
	
	if rayResult.Instance:IsDescendantOf(Models.Barriers) then 
		moveTo(obj.Humanoid, rayResult.Position)
		obj.Humanoid.MoveToFinished:Wait()
		wallDestruction(obj,rayResult.Instance)

		repeat wait() until Breach.Value == true
		
		obj.Head.Material = "Neon"
		obj.Head.BrickColor = BrickColor.Red()
		
		rayResult.Instance.Velocity = rayResult.Instance.CFrame.LookVector * -50 

		local getPath = findPath(obj.HumanoidRootPart, workspace.BaseCore)

		local waypoints = getPath:GetWaypoints()
		for i, v in pairs(waypoints) do
			obj.Humanoid:MoveTo(v.Position)
			obj.Humanoid.MoveToFinished:Wait()
		end 
	end
end

Most likely its not your raycast function but rather how you call it.

Maybe. This is how I call the function which is with the InstanceAdded event.

Collection:GetInstanceAddedSignal(Tag):Connect(function(obj)
	attackPosition(obj)
	obj.Humanoid.Died:Connect(function()
		removeDummy(obj)
	end)
end)
