When I Play my game in the editor or export it to Windows Standalone the AI characters I have will work as they should and follow my player around etc.
When I export to the Web Player however, the AI characters walk on the spot and seem to be ‘stuck’ in place. They do not shoot or any of that either, just walking on the spot.
Any ideas as to why this would work in Editor/Windows Standalone, yet not in the Web Player?
Thanks.
Do you have external data files that might not be getting loaded?
hmm I’m really not sure. Everthing is the same as I usually have them…
Could you perhaps give an example of an external data file that I could be using and not loading? I’m not 100% sure I know what you are referring to 
Thanks!
Anything using File.Load or StreamReaders etc. Searching for System.IO will show you classes which may be using local File IO.
Thanks for the suggestion 
I checked it though out and that sort of thing doesn’t seem to be the culprit here…
What I have noticed is that it seems as though my AI characters are not recognising my ‘Player’ object as thier ‘target’. I’m a bit confused as to how this would be different in the Web Player compared with the Windows Stand Alone export…
This is the script I am using for my AI. The ‘target’ variable is what I’m looking at. I notice that if I physically drag the ‘Player’ prefab onto the target variable slot in my gui I get the same result as what I see in the Web Player export. Basically that variable get set in the code so it seems to only work if I don’t physically drag the prefab onto it, only if it’s empty in the Inspector??
Yet if I ensure the AI character’s Target IS empty in inspector, it won’t work in Web Export but will in windows export and in the editor?
Perhaps someone can take a look at this code and tell me if i’m missing something here? Or is there something differnt in the web exporter that I’m unaware of?

Fixed it.
Problem was quite hard to find. I had added my original character with the tag ‘Player’ to another prefab which I gave the tag ‘Player’ also with out thinking about it.
When I took the ‘Player’ tag off of the first prefab set and left it on the top level prefab it works.
I’ve no idea why it would work in the Editor and Windows Standalone but not in Web Player the way that it was, but there you go. I’m just glad it’s resolved.
