Unable to cast Vector3 in Pathfinding script?
I'm trying to make the npc to move to the current place it is supposed to but it doesn't.
In the output it says,Unable to cast Vector3. the error is in line 5,any help?
local torso = script.Parent.Torso.Position
local base = game.Workspace.Base
local human = script.Parent.Humanoid
local path = game:GetService("PathfindingService"):FindPathAsync(torso,base)
local points = path:GetWayPoints()
for i,v in pairs(points) do
local p = Instance.new("Part",workspace)
p.Anchored = true
p.CanCollide = false
p.Size = Vector3.new("1,1,1")
p.CFrame = CFrame.new(v.Position)
end
if path.Status == Enum.PathStatus.Success then
for i,v in pairs(points) do
human:MoveTo(v.Position)
human.MoveToFinished:Wait()
end
end
This script is in the model of the npc.

your first argument is a Vector3 and your second is a userdata. add `.Position` to the end of line 2 Gey4Jesus69 2705 — 6y

but `:FindPathAsync()` is deprecated in favor of `:CreatePath()` so u should look into that: https://developer.roblox.com/api-reference/function/PathfindingService/CreatePath Gey4Jesus69 2705 — 6y

In the output, it says "Unable to cast Vector3 to Instance."
You're using the base part itself and not its position.
Sometimes I make this mistake too, but thanks to the output window, I'm able to fix it quickly on my own.
Here is the code you should use...
local torso = script.Parent.Torso.Position
local base = game.Workspace.Base.Position
local human = script.Parent.Humanoid
local path = game:GetService("PathfindingService"):CreatePath()
path:ComputeAsync(torso,base)
local points = path:GetWaypoints()
for i,v in pairs(points) do
local p = Instance.new("Part",workspace)
p.Anchored = true
p.CanCollide = false
p.Size = Vector3.new("1,1,1")
p.CFrame = CFrame.new(v.Position)
end
if path.Status == Enum.PathStatus.Success then
for i,v in pairs(points) do
human:MoveTo(v.Position)
human.MoveToFinished:Wait()
end
end

When I put Position in,It says GetWayPoints is not a valid memeber of path. rochel89 42 — 6y
