I think this was the issue.

I now have one ball with bounce off solids: yes

a second ball with bounce off solids: no

Seems to be working. Thanks!

Haha, don't want to share my whole game :) So, I'll make a mini version I guess. Thanks.

Yes. Definitely did that. That's a key thing for new users, and got me on my first game before discovering it. Thanks though.

I basically have a ball that I don't want touched while it's in the air. (It's a field goal, can't block it past the line of scrimmage, so I want no collisions past that event)

I want a ball to convert from solid enabled to solid disabled after an event, but it doesn't seem to do that despite my code.

The ball keep colliding with objects that I have ALSO changed to disabled after the same event.

So, five sprites all solid enabled.

After event, all five go to solid disabled.

But, it seems to be ignoring me.
