Are there known problems causing some elements of a collection to disappear?
I check them at one moment and they are ok and a moment after some of the elements have vanished.
My code is fairly long so I can't post it here but There are absolutely no delete statements inside.
What's more puzzling is that some variables assigned to these elements still hold them although I don't see them when I make a for each loop
Any idea?
It is very much more likely to be something odd you have in your code than a problem with Blitz itself.
Something to look out for: are you using the variable for the Each loop anywhere else in the loop? This could lead to skipping of items.
I haven't had any problems. I think Blitz is so mature now such errors would have been found out long ago. More likely you're overwriting/skipping an element of a type. When I get weird behaviour it's because, when I eventually find it, I'm doing something earlier on with an object that messes up it's later access.
I've only encountered this once, but It will delete the one you pass to a function, if the function uses it in a foreach loop and you use it in a foreach loop afterwards.
Type t
Field x
End Type
a.t=New t
a\x=2
a.t=New t
a\x=5
b.t=New t
b\x=6
hi(a)
Print
For a.t=Each t
Print a\x
Next
WaitKey
End
Function hi(z.t)
For z=Each t
Print z\x
Next
End Function
Corrorae , I think you are describing exactly my problem, I wil investigate further.
Just make sure you aren't doing this:
Function DoSomething(g.guy)
For g=Each guy
Just make sure you aren't doing this:
Function DoSomething(g.guy)
For g=Each guy
That indeed was the problem. It took me a little while to find the faulty functions.
Thanks everybody for your answers
