I'm using Director 6 so I can't use dot syntax :(
Allow me to get a little more detailed.
FileIO obviously doesn't overwrite an entire text file
when it writes to a file, it just writes from char a to char b.
If there are more characters already in the text file beyond
char b, they remain untouched.
I have a linear list I am saving to a text file.
I am converting the linear list to a string and removing
the brackets and quotes. Let's say the end result is a
string 100 characters long.
I write the 100 character long string to a text file.
Now, in one case, the string is 101 characters long, and
it writes that to the text file. Now the text file is 101
characters long.
If I write my 100 character long string to that text file,
it only overwrites the first 100 characters of the text
file, leaving character 101 there. The next time I read
that file, it reads the last item in the list with a 0
at the end of it, which effectively breaks my code.
I tried to add a space to the end of the string to overwrite
the trailing zero, but when it wrote 3110 it wrote "3110 "
which added 2 spaces to the overall length. Same problem.
I've decided that the only way to really handle this is to
do a short repeat where it checks to see if the last char
of the string is a space, and if so, delete it. This should
solve the problem, in theory. If you have any other ideas,
please let me know.
