I'm not sure if this is possible. I went though C2 last night and posted on the forum a couple of days ago, but no one replied, so I'm going to assume that there isn't any way of doing it yet.
My idea is that we could export C2 Objects as C2 Exclusive readable files.
I though of this because i am working on two projects that have pretty much all of the assets the same. I felt it was going to be tedious to have to recreate all my assets twice over.
Basically, I think you should be able to export the following, just one or in bulk, as a C2-readable file, something like MonsterSprite.caxpt:
Each .CAXPT file can include the object, any instance variables, and any related Events or Event Sheets for easy sharing between projects , and even to other C2 Users aswell. People could share their animations and game mechanics this way.
