So uh what did i did wrong?
local path = PathfindingService:CreatePath{ AgentRadius = 0.75, AgentHeight = 66.001, AgentCanJump = false, -- New parameter -- Costs = { RaceCheck = math.huge, Barrier = math.huge } }
AgentRadius should be the width of your car in studs and I doubt your car is less than 1 stud wide. Your Costs are fine. Have you added the PathfindingModifier to the items? If yes, then double check that you have the CanQuery property ticked.
