Events are able to invoke other events, but only up to a certain limit (currently 200). When this limit is reached, events stop invoking, existing threads resolve normally, and the following error is emitted:
Exception caught in TGenericSlotWrapper. C stack overflow
Firstly, it would be helpful if this limit could be clarified as being intentional or not. Secondly, assuming that it is intentional, the error message should be more informative.
The following code demonstrates this behavior:
local values = {Instance.new("IntValue")}
local function changed(v)
values[#values+1] = Instance.new("IntValue")
values[#values].Changed:Connect(changed)
values[#values].Value = v + 1
end
values[1].Changed:Connect(changed)
values[1].Value = 1
for i = 1, #values do
print(i, values[i].Value)
end
This produces the following output:
Exception caught in TGenericSlotWrapper. C stack overflow
