An object may have a bullet behavior or physics behavior that uses impulse to move into the layout. My problem is that I don't know how to destroy something that enters a layout and once it leaves, to destroy it.
I realize I could use the fade behavior but for many of the objects within my game, they need to have full opacity, although I have found the fade have found the fade behavior to be useful for certain objects. Elongating the fade out time isn't useful because I will usually have objects being destroyed once outside layout to prevent performance issues.
Of course I've thought about using the Destroy Outside Layout behavior but an object will be destroyed if it's coming from outside the layout.
Here's a capx of what I mean:
The Balls coming from the left are bullet, the balls coming from above are impulsed. Once they exit the layout, how do I destroy them?
