Permanent freeze with Pathfinding having WaypointSpacing=0 and ending Playtest

[Judgy_Oreo (phoenixwhitefire)]

Repro steps:

1. Download and open the Repro File:
   pathfinding-freeze-test.rbxl (53.9 KB)
2. Press F8 or click Run button
3. Shift+F5> or click Stop Playtest button

Expected behavior:
The playtest should end. The :ComputePath call should (probably) error instead of freezing and never returning, giving a message such as “WaypointSpacing cannot be 0”.

Actual behavior:

As seen above, when I hit the “Stop playtest” button, Studio freezes and can’t be interacted with, as the Pathfinding computation never finishes on the pathfinding thread (or, that’s what I assume is occurring).

Occurs regardless of whether the new algorithm is used.

Frequency: Always
First experienced: (Likely) over a year ago

Hi Judgy_Oreo,

We wanted to let you know that a fix for this issue has been released. Using a WaypointSpacing value of zero should no longer prevent pathfinding from completing or cause Studio to become unresponsive. Values less than zero will now also be clamped to a valid spacing distance. Thanks again for your report!
