How to use the new pathfinding modifiers?

Help and Feedback Scripting Support
#1

I am trying to make an npc ignore doors in its pathfinding so it can walk through them using the new pathfinding modifiers, but I can’t seem to figure out how to use them. He still justs walks around the wall with the door like this:

https://gyazo.com/18c2e9989e37e9f44f84b0eda9a7834a

Here is the script:

local hum = script.Parent.Humanoid
local root = script.Parent:FindFirstChild("HumanoidRootPart") or script.Parent:FindFirstChild("Torso")

local goal = workspace.Goal.Position



local modifier = Instance.new("PathfindingModifier")
modifier.ModifierId = "Door"
modifier.Parent = workspace.Door

local agentparams = {
	AgentRaduis = 2,
	AgentCanJump = false,
	Costs = {
		Door = 1.0
	}
}

local path = game:GetService("PathfindingService"):CreatePath(agentparams)

local visualizepoints = true

path:ComputeAsync(root.Position, goal)

local waypoints = path:GetWaypoints()

for _, waypoint in ipairs(waypoints) do
	
	if visualizepoints == true then
		local part = Instance.new("Part")
		part.Shape = "Ball"
		part.Material = "Neon"
		part.Size = Vector3.new(0.6, 0.6, 0.6)
		part.Position = waypoint.Position + Vector3.new(0, 2, 0)
		part.Anchored = true
		part.CanCollide = false
		part.Parent = workspace
	end
	
	hum:MoveTo(waypoint.Position)
	
	
	hum.MoveToFinished:Wait()
end

The door is a model and the door is set to open when the character touches any of its parts in the model.

Have you made sure to tick PassThrough on the Pathfinding modifier?

#3

As koziahss already said.

I don’t see you enable true on PassThrough?

local modifier = Instance.new("PathfindingModifier")
modifier.ModifierId = "Door"
modifier.PassThrough = true
modifier.Parent = workspace.Door
#4

I set it to true but the npc still goes around the door, does the modifier work for models?

#5

I’m not very good at pathfinding, but no, it doesn’t work on the model.

But you can use for i,v in pairs() loop:

for _, door_part in pairs(workspace.Door:GetDescendants()) do
     if door_part:IsA("BasePart") or door_part:IsA("MeshPart") then

           local modifier = Instance.new("PathfindingModifier")
           modifier.ModifierId = "Door"
           modifier.PassThrough = true
           modifier.Parent = door_part
    end
end

This is the first thing that came to my mind.

So do I need to just create separate modifiers for each individual part in the model? I can’t really do that since there will be alot of doors on the map, is there any alternative?

#7

I tried creating a part called doorvolume sort of like the example shown in the post showcasing the new modifiers but it still doesn’t work:

local hum = script.Parent.Humanoid
local root = script.Parent:FindFirstChild("HumanoidRootPart") or script.Parent:FindFirstChild("Torso")

local goal = workspace.Goal.Position


local modifierVolume = workspace.Door.DoorVolume

local modifier = Instance.new("PathfindingModifier", modifierVolume)
modifier.ModifierId = "Door"
modifier.PassThrough = true
modifier.Parent = workspace.Door

local agentparams = {
	AgentRaduis = 2,
	AgentCanJump = false,
	Costs = {
		Door = 0
	}
}

local path = game:GetService("PathfindingService"):CreatePath(agentparams)

local visualizepoints = true

path:ComputeAsync(root.Position, goal)

local waypoints = path:GetWaypoints()

for _, waypoint in ipairs(waypoints) do
	
	if visualizepoints == true then
		local part = Instance.new("Part")
		part.Shape = "Ball"
		part.Material = "Neon"
		part.Size = Vector3.new(0.6, 0.6, 0.6)
		part.Position = waypoint.Position + Vector3.new(0, 2, 0)
		part.Anchored = true
		part.CanCollide = false
		part.Parent = workspace
	end
	
	hum:MoveTo(waypoint.Position)
	
	
	hum.MoveToFinished:Wait()
end

I have tried with a cost of 0, 0.5, and 1.0 and still he just wont try it

Your edit worked! He finally paths to the doors now! Thanks!

#9

Have you tried manually adding PathfindingModifier? If that doesn’t work, then I don’t even know what it might be.

I’m glad that helped, good luck! :grinning:
