Receiving a 0 out of nowhere?

[Perry]

I have this example, and it generates the numbers that are in the 3 listboxes.
now randomly there is a 0 in between, while I have no 0 in the lines at all.

I played with the 0 and 1 index, but the problem keeps happening.
Played with this for 6 hours and I can't figure out why this keeps happening.


I have 24 numbers in each list. 1..24, so I use a Rrandom ( 1,24)
then I grab the value that is in the listbox on on that position (1..24) and assign it to a counter.

Now the trick is that it's

AAA
123
BBB

so 1,2 and 3 are in the middle, and A,A,A is the value BEFORE 1,2, and 3
and with B,B,B the value AFTER 1,2,3
(both from the listbox)

so, if I have in 1,2,3 the value from list entry 24,24,24
then A,A,A is 23,23,23 and B,B,B is 1,1,1

and if 1,2,3 is 1,1,1 then A,A,A is 24,24,24 and B,B,B is 2,2,2

so I should have cached everything, but still there is a number 0 randomly.

Any ideas?

(not sure where the 1 response went but anyways)..

It happens in all the rows. (if you press long enough).
if the number is > then the list it will go to the 1st one, so there shouldn't be a 0.

I haven't been able to find a bug yet with rrandom

I am suspecting something going on with the list boxes --
Idea can you set them visible and also select the line they are selecting so you can see if the problem is coming from this someplace.

The first response was mine, but it was a mistake :p Im sorry you had to see it, I deleted it within like a minute xP

[Perry]

I will try it when I get home tonight.

it probably happens 2-4 times out of 20

then one the numbers is 0
Will add the Select line as well (Thought it was only needed for deleting an item)

I am just suggesting the select line so we(you) can visually see whats going on so we can track down the bug/issue.

I'm not at my computer now so I can't check your mfa, but from what I understand of the problem I would guess the following:

If you try and get a list item that is after the end of your list or an item that is before the start of your list then it will return 0

[Perry]

That's what it looks like.
But I put in 2 events that should prevent that.
1 event with if xx = 1 and xx = 24 (so it's the beginning and the end of the list)
sometimes it's fine and sometimes it's not.

But can't test atm. have to wait 6 more hours

[Perry]

playing with it, and getting the impression that the 1 based index is not working for the list

I've found the problem.
I'll explain using the counter named t9 as an example.

In Event 5 you set t9 to the value of a line in Reel3 between and including 3 and 26, since Counter 7 can be anything from 1 to 24, and you add 2.
This means that the list can be set to line 25 or 26 which doen't exist, and it produces 0.
In Event 11 you test if Counter 7 is 24, but that doesn't prevent it from going higher. What you should test for is: Counter 7 + 2 > 24.

Another workaround instead of what you do in Event 11 could be to use the max() and min() functions to prevent the values from being anything outside 1 and 24.
