[AS3] difficult collision detection
So I have a monster on the stage.
I also have a character, and inside of the character symbol, a throwing knife symbol.
Inside of the throwing knife, I made a motion tweet to throw the knife each direction (left and right).
The throwing knife x and y coordinates do not change, as the knife just moves accross the symbol.
So between the monster and the throwing knive, nothing is moving.
However, how do I test when they overlap each other??
