This is the error
[ERROR] gamemodes/taloslife/gamemode/cl_networking.lua:99: attempt to index a nil value
This is the file:
Can't add it because of maximum word length, but here's the code block in which 99 is in
function GM.Net:GetProtocolIDByName( strProtocol )
return self.m_tblProtocols.Names[strProtocol].ID
end
I really can not figure out what's wrong with this, If anyone could please tell me the fix it would be greatly appreciated. I have spent hours looking into this and can't find the fix.
When you read something that is not there in Names table, you will get nil.
return self.m_tblProtocols.Names[strProtocol].ID
And then you're trying to get ID field from nil value, so you get this "attempt to index nil" error.
Check if protocol name is saved in that table first.

I need help understanding this runtime error. I am fairly sure that the below is the problem, but have not been able to find a solution that works.
Parallel.ForEach(Of String)(Me.clb1.SelectedItems,
Sub(clb1)
Parallel.ForEach(of String)(Me.CheckedListBox1.SelectedItems,
Sub(xxx) <-Not sure what goes here.
The error message highlights the entire Sub but the rest was cut and pasted from working code.
I read the instructions of Lambda and found a simpler example. The is dawned on me what I needed to do.
For cnt = 0 To ListBox1.Items.Count - 1
MyFiles.Add(ListBox1.Items(cnt))
Next
Parallel.ForEach(MyFiles, Sub(F)
Now I need to fix the code to handle the multi-threading code, but that is another question that I am not ready to ask yet. Thanks.
I suspect this is a problem with a really simple solution. Essentially, if I use a variable to index an array, I get a nil error, but if I use a direct number, there is no issue. What about the variable could make it unusuable?
npcs[a].plotFind = 7
file:write("\n ".. npcs[a].plotarray[7].y) -- Doesn't produce a nil error
file:write("\n ".. npcs[a].plotarray[plotFind].y) -- Does produce a nil error
plotFind equals 7, and yet, the third line of code here produces a nil error, while the second line doesn't.
Oh my goodness, plotFind isn't the variable. npcs[a].plotFind is. I am dumb. Nevermind. Forgive my stupid.
I tried to access the following value in an multidimensional array:
var temp = allSliderData[i]['slider_full'][j].path;
and it works fine, but the following not
var temp2 = allSliderData[i]['slider_thumbs'][j].285x255;
with the answer
"SyntaxError: identifier starts immediately after numeric literal"
I now tried escapings, array functions .. this message is good known in stackoverflow .. but still no luck.
Could anybody help out?
THANKS!!
Something like that won't work. You can't have a property named "2" there. What exactly do you want to do?
Hello I've done multiple python programs since I started and an error is occurring quite often for a short time and I don't understand why there is an error or why by just changing random things so the program does the same gets rid of it so can anybody please explain how the "referenced before assignment" error occurs please.
Here's the code with the problem:
def compter(sequence, element):
comtpe=0
for i in sequence:
if element==sequence[i]:
compte+=1
return compte
compter([1,2,1,1], 1)
please explain so I could be able to get rid of it in any future code thank you very much :)
(I'musing python 2.7.6)
Am trying to find whether one field is sub string of another field by using INDEXOF(f1,f2) > -1 where f1,f2 are both char arrays. But am getting error message as "Scalars can be only used with projections".
Is this error message because of, lack of support for two variables comparison in INDEXOF or something else? Can some one help with this?
Thanks in advance.
