How do I pick an object that is not in the pick list?

I have 2 triggerBoxes, "left" and "right". When the player collides with the left one, I want to do something to the right one. But the on-collision picks the left one, so the right one's no longer available to pick, and the second condition never evaluates to True. So how do I pick the right one in this situation?

As a stop-gap I've set a flag on collision with the left one, and if that flag is true I do what I need to do to the right one and reset the flag. But is there a cleaner way to do this?

Try this:

+ player: Is overlapping box

+ System: Trigger once

----+ System: Pick all box

----+ box: [X] Is overlapping player

-----> box: Rotate 15 degrees clockwise

That way will makes other box that isn't overlapping with player to rotates. In short player touch a box other box will respond

Alextro is correct. Add a pick all event to reset the pick list.

Add a pick all event to reset the pick list.

That's gold, thanks guys!
