Note that this is single inheritance, not true library-style multiple inheritance. You may wish to follow my advice described here:

Where do/should Gateway Scripts live with respect to an inherited project structure?

Put all of the logic in project library scripts, in the "universe" project at the root of your hierarchy, if you must. Then, in leaf projects, use one-line calls to the appropriate logic from event scripts and message handlers. (I don't agree with your desire, but this is what you must do to achieve it.) I recommend you not put all your scripts (eggs) in one inheritable project (basket). I recommend a hierarchy something like this: universe ├bg_common │├gsp │├background1 │├background2 │└we…
