How do I Invert SOL (Selected Object List)

How do I do this? Already thought of running an inverted pick condition, but that approach doubles the overhead. Is there any way to just invert the pick list?

Let's say picked object is overlapped by a detector. So the remain objects that were not picked will be not overlapped by any of these detector;

system: object is overlapping detector (inverted) | do an action

That is my first solution.

Other method that also work is by inverted the instance variable (boolean);

system: is picked (inverted) | do an action

Did you try else?

The object in question (laser beam) as a collision polygon, but the object it is being tested against (a circular shield) doesn't. However, since there is only 1 shield, I could add a polygon. Actually, yours is a pretty good idea. Thanks

My first thought, but I found that else doesn't work that way: it won't invert a pick list.

Actually, there is a thread around from a couple of years ago where Ashley was discussing whether or not to have else invert SOL's in the context of a pick condition. However, he decided against it.

If I remember correctly, "Else" resets the SOL altogether.

Not sure what you want to do.

In my experience on of the better methods to break out of picking is to use a function.
