Proper stack tracing

Help and Feedback Scripting Support

So, while I’m still working on my event handler, I’m curious on how to control stack tracing.

Lets say for instance, I have a function that calls another function:

local function a()
    error("This shouldn't go past b", 3);
end

local function b()
    a();
end

b();

As we know, if the error level is past the stack, then it will not stacktrace it, just like setting the level to 0. So, how do I prevent the stack level from going past b, or in this case, 2?

How does Roblox do this in their Event handler? If you set the level past the :Connect function, it will not stacktrace it.

debug.traceback() if you weren’t aware of it already.

#3

That’s to get the trace, not limit it

#4

coroutines don’t unwrap the active function stack upon an error occurring.

So how does roblox do it then?

No, I mean use coroutines if you want to limit the traceback.
