Equipped and Unequipped firing twice

MrHistory · July 1, 2016, 4:00am

I narrowed the problem down to a critical line in each of the Equipped and Unequipped listener functions. I specified them in the repro. The two lines move a GUI inside the tool to PlayerGui and back respectively. This is causing the Equipped and Unequipped events to be fired twice.

I found a related thread:

Behavior causes Tool.Equipped to fire recursively

Engine bug

When an object is added to the character via a listener connected to the Equippe…d event, the Equipped event fires once again. This causes the maximum re-entrancy depth to be exceeded. ``` Tool.Equipped:connect(function() local v = Instance.new("IntValue") v.Parent = Character end) ``` This does not occur after the listener thread yields. ``` Tool.Equipped:connect(function() wait() local v = Instance.new("IntValue") v.Parent = Character end) ```

Why hasn’t this been fixed yet?
