Cheaters?
 
Hi:

I'm using Alice to teach introductory animation.
I'm getting assignments that look suspiciously similar and was wondering if there was some kind of file property I could use to definitively check for duplicates?
File creation date/time works well in Office files as a kind of file "fingerprint", is there something similarly unique for .a2w files?

Any help would be appreciated,

Rick

Hi,
I used a program to generate checksums. I cant remember what it was called on windows for sure but I think it was something like mssum.
If the files are exactly the same they will have the same checksum and the chance that two students would drag all the objects to the exact same place in two different movies, even if they try is remote.

That being said make sure the students know that they cannot work together with one person doing the authoring and then copy the results and hand them in.

Thanks Mark
 
Thanks Mark.
Using a checksum utility I was able to confirm that the 2 files in question were identical.
Checksum is pretty definitive, right down to bit level.
