Sword cut effect with falling paper

Question

okok the title is a bit ahrd to understand, i try to explain
i want to create an effect where
i use a sound of a sword that slash 3-4 times
i want to make an: objector a text or something hide from a black screen by "cutting" the black screen and make the black screen fall in pieces like jigen in lupin when he cut something then the object will fall in some pieces BUT the falling position must start from the original form
like i have a circle that hide the word hello
i use the sound of the sword to give the idea of the cut
the piece of the black circle (not like particle effect) start to fall, in example i make 4 slash then the circle is divided in 4 pieces that will fall revealing his hide text
the text is not a problem, i just want to know how to make this effect, can't find any example video on internet

Answer 1

If it's still confusing check out this screenshot.  This is how I'd do it at least.
a.) Make an eliptical mask on your layer
b.) Press the Y key, then click and drag while holding the Command key to snap the anchor point to the center corner of your layer.
c.) Then duplicate the first layer and change the rotation to 90
d.) Duplicate the second layer and change the rotation to 180
e.) Duplicate the third layer and change the rotation to 270
f.) Then clean up your masks to get rid of the white gaps in the middle of your shape so it looks whole.
