OK, here's some things to try.
1. Don't try to set fire to something you already have, create the object and set the scripts in one session.
2.On the scripts tab, make sure you have Advanced clicked. This should give you the AttachAnimatedSprite.
3. Set the Scale to at least 200.
Plus all the other things mentioned.
These are things that I found worked for me.
Now to get to work on my sea turtle swimming.
I admit, I don't have an answer for everything. I do however have an opinion on everything. Just ask me.
