I haven't actually tried this but looking how I'd go about trying to solve it, I'd give the object a movement behavior, bullet might work.
Bullet then has event options that allow you to "compare distance traveled" and or "compare speed", set values for those and trigger a destroy action.
Like I say, I haven't tried this but I think that would work if you set the bullet speed to 0 initially and set it's angle to 90.
Edit: Just tried it and it works fine!
You might need to change "compare distance traveled" to get a distance from the floor depending on how you want it to work.Zantium2013-06-28 22:13:58
