According to the DevHub page, the default agent parameters of the pathfinding service are AgentRadius = 2, AgentHeight = 5, and AgentCanJump = true.
It looks like either these given defaults are wrong, or the PathfindingService is using the radius argument wrong. Radius 2 should be able to fit through a 4 stud wide gap, but it doesn’t. It needs to be less than 1.75 to fit through the 4 stud gap.
When I use the pathfinding service without using any parameters at all, the pathfinding service works as it should.
pathservice:CreatePath()
However, when I manually put in agent parameters which have the same values as the defaults listed on the DevHub, no path can be calculated.
pathservice:CreatePath({AgentRadius = 2, AgentHeight = 5, AgentCanJump = true})
To get the closest behavior to what the defaults appear to be, I have to use the following:
pathservice:CreatePath({AgentRadius = 0.98, AgentHeight = 5, AgentCanJump = true})
Here is the code used in the repro file.
To make it work, all I do is use the nil or guesstimated “details” variables.
local details = {AgentRadius = 2, AgentHeight = 5, AgentCanJump = true} -- DevHub-given defaults
--local details = {AgentRadius = 0.98, AgentHeight = 5, AgentCanJump = true} -- Guesstimated actual defaults
--local details = nil -- No argument, use built-in defaults
local pathservice = game:GetService("PathfindingService")
local path = pathservice:CreatePath(details)
local points = {}
while wait(0.3) do
path:ComputeAsync(workspace.start.Position, workspace.theend.Position)
print(path.Status)
local waypoints = path:GetWaypoints()
for i, v in pairs(points) do
v:Destroy()
end
points = {}
for i, v in pairs(waypoints) do
local part = Instance.new("Part")
part.Name = "waypoint"
--part.Shape = Enum.PartType.Ball
part.Color = Color3.new(1, 1, 1)
part.Material = Enum.Material.Neon
part.Anchored = true
part.Size = Vector3.new(.5, .5, .5)
part.Position = v.Position
part.CanCollide = false
part.Parent = workspace
table.insert(points, part)
end
end
This bug works every time, and I tested it in Studio and in a game. My computer runs Mac 10.14.6.
