How do I Cut out a piece of my Sprite

Hey guys,

im pretty confused about the different layers in Construct 2, ive kind of got it right in my project but am stuck now...

I've experimented with some shadows and stuff and basicly what i need to know now is how to cut out a part of an Sprite with the shape of another Sprite.

Like Here:

(sorry i haven't enouth rep for now)

The black thingy should be transparent and should erase the part of the white thingy... you know what i mean?

Where the black square is right now there should be the blank background :/

thanks 4 your help

Use "destination out" blend mode. There is an example called "Lighting demo" in examples.
