how do you use mask?

I made a sprite, white fading to no opacity

when I turn the mask effect on, the white part is see through

and the transparent parts are black

I thought it would make whatever was under the transparent parts invisible,

the background of my project I made blue, so I could make sure it wasn't just masking all the way to the bottom

any help would be appreciated

Put it on a layer with "Force own texture" enabled and it will cut a hole in the layer.

oh wow

thanks, I can't wait to post a cap of the stuff I've been working on

construct is about 1903891283 times more amazing then I even thought possible
