Remove line 34 from your RealWorld class.

nothing still happens but when i put the hitTrash() method on the Health bar actor, the healthbar decreases once?

You are not resetting touchingTrash back to false when you are no longer touching the trash. So the health would only decrease once in the above code (after danpost's suggestion which clears up another issue). You need to add an else on the if (Trash != null) to set touchingTrash to false.
