I’ve looked in literally every post i seen yet nobody spoken about it before, could be a bug?

local PathfindingService = game:GetService("PathfindingService")

local folder = workspace:WaitForChild("e")

local start = folder:WaitForChild("Start")
local marker = folder:WaitForChild("Point")
local goal = folder:WaitForChild("goal")

local path = PathfindingService:CreatePath()

local fr= path:ComputeAsync(start.Position,goal.Position)


print(fr)

path:ComputeAsync doesn’t return anything, you have to call path:GetWaypoints to get the waypoints.

Can you please look at attachments?Im not stuipid
Thanks

#4

i suspect that roblox force my roblox studio to toggle random beta feature without my knowledge
Otherwise it could be a bug.Thanks all for trying to help but next time please look at attachments

#5

Not sure why your getting iffy, looking at the attachments, I dont see GetWaypoints anywhere. Use GetWaypoints in the script, so instead of

local fr= path:ComputeAsync(start.Position,goal.Position)

have

local fr= path:GetWaypoints(start.Position,goal.Position)
#6

how could you use method on nil? bro :skull::skull:
by the way this issue is still not solved i gonna try looking at beta features

#7

Well we’re tryna help, and its not “path” returning nil, it’s your “fr”, which your not using a method on.

Not sure why your so toxic when were tryna help :+1:

#8

Oh im sorry i dont trying to be toxic
I just dont understand why pathfinding returns nil
also no your solution does not work i tried it

#9

i just tested removing beta features and it does not help
i prob should open bug report for it
But i dont have access to such category i think

:ComputeAsync() not returning anything isn’t a bug. As previously explained by @CloudSnooze :ComputeAsync() doesn’t return anything on purpose and instead computes a created paths waypoints. To actually get the paths waypoints you have to call :GetWaypoints() on the path you made using :CreatePath().

Doesn’t work as :ComputeAsync() only computes a path and does not return its waypoints:

local PathfindingService = game:GetService("PathfindingService")

local folder = workspace:WaitForChild("e")

local start = folder:WaitForChild("Start")
local marker = folder:WaitForChild("Point")
local goal = folder:WaitForChild("goal")

local path = PathfindingService:CreatePath()

local fr= path:ComputeAsync(start.Position,goal.Position) --Doesn't return anything


print(fr)

The correct implementation would look like this:

local PathfindingService = game:GetService("PathfindingService")

local folder = workspace:WaitForChild("e")

local start = folder:WaitForChild("Start")
local marker = folder:WaitForChild("Point")
local goal = folder:WaitForChild("goal")

local path = PathfindingService:CreatePath()

path:ComputeAsync(start.Position,goal.Position) --Computes the path and doesn't return anything

local fr = path:GetWaypoints() --Actually returns the previously computed waypoints

print(fr)

If you need any additional help you can refer to the official documentation on paths:
