Ok, so, I've been trying for two days to get bullet logic to work, and I've been having a lot of issues with it because the object it's colliding with is another of the same object. It would send them all shooting around the board, or sliding to the right, even with the angle set to 270. (I still think it might work, it's just beyond my newbie knowhow.)
So I did a simple move instead, creating two new variables to control which "dots" can collide and bounce. It's working, but it's not great. They hit and pop up like popcorn and I can't get them to go very high, or they fall and settle at various heights, skewing each new object that comes in afterward.
I'd really like a nice, smooth bounce instead of a jarring pop. I'm thinking I'll need to use physics, but I am not sure how.
This is what I have:
