Why am I exceeding the re-entrancy depth?

Intermediate Scripter Posts : 17 Join date : 2012-06-27

Hi everyone,

I'm having a weird issue where, when my tool is equipped, my onSelected function runs six times, then the script is terminated, with the output saying maximum event re-entrancy depth exceeded.

Looking at a snippet of my code,

Code:: me = nil --Tools are placed in the Character model when they're taken out, this variable must be set once the tool is taken out.
msg = nil

function onSelected(mouse)
print("Selected Local")
me = script.Parent.Parent
mouse.Icon = Cursor["gun"]
--mouse.Button1Down:connect(function() onButton1Down(mouse) end)
--mouse.Button1Up:connect(function() onButton1Up(mouse) end)
--mouse.Idle:connect(function() Idle(mouse) end)
--mouse.KeyDown:connect(keypush)
msg = Instance.new("Message")
msg.Parent = me
msg.Text = ""
print("Message placed in "..tostring(me))
end

bin.Equipped:connect(onSelected)

can anyone tell why this function is being repeated multiple times when it should only run once?

This error means that too many events immediatly fire the same event which fires the same event again and into infinity....

Thanks for the help frogy,

I posted this on the roblox forums, and it turned out to be something a little more complicated than that - it actually was a bug in roblox its self. The suggested temporary workaround was to put a wait(0) command at the beginning of the hooked function that was causing the issue. I hope this bug gets fixed soon :\

do

[code]local debounce = true

if (debounce == true) do
blah blah onEquipped blah blah
debounce = false

STUFF................
end

Oh, was that thing old? I never really noticed, thanks for getting it for me though :)

Yeah, it was the weirdest thing... I actually tried the debounce method first (that was the first suggestion over at roblox), and for some reason, (as best as I can remember) I was still getting the same results, more or less. I don't completely understand why that wouldn't work where the wait(0) method would, but I sure like it since it's less code :)

It's sure odd.

It is.... But it's nice to know that there are more than just two people active on the forum.

Hate to go offtopic, but is activity an issue here?

Intermediate Scripter Posts : 143 Join date : 2012-07-14

Nope. Not really, but I was just showing my happiness that you are also active.

Intermediate Scripter Posts : 17 Join date : 2012-06-27

Oh, why thank you :) I'm glad to be active here.

The Garbageman Posts : 336 Join date : 2011-06-23

Well, I'll promote you, since I can see you're better than a novice. :D

That's very kind of you to do for him. Thank you! And, Welcome to being a Moderate Scripter, tgp1994!

Thank you both :) I wish I was more active on ROBLOX to better deserve the title, but I appreciate it nonetheless.

Hey, as long as you are active to some extent, we appreciate it. You are helping to keep the forum alive.

The Garbageman Posts : 336 Join date : 2011-06-23

Yup. Couldn't have coined it better.

If you're still having issues with this, I can look at the code for you and definitely give you a fix. I've had problems like this multiple times.

Hey, MrNicNac! Nice to see you, again! [Even though I've never met you>:3 ]. I'm sure they would love having your help on their probloems.

Intermediate Scripter Posts : 17 Join date : 2012-06-27

I appreciate the offer, MrNicNac! I think the wait command actually worked very well for the script (and for me, I might add :P) If you have a better solution, would you mind posting it here so the community can benefit from it?

Expert Scripter Posts : 27 Join date : 2011-03-06 Age : 28

No, my offer would have been to add a wait somewhere as well.

I just have to ask, however, did you use a LocalScript?

I'm trying to think back... I was going back and forth between a LocalScript and a regular script, because I needed to interact with the world, yet I was hearing stories that the localscript would be a solution (although I don't remember switching to one actually fixing anything). It seemed like it would be much more easier leaving the script as a serverside script, so I think I may have left it serverside.

Why am I exceeding the re-entrancy depth?

Got a really good idea? Post it in projects and it might show up here!
