How do I Cutout circle sprite

Hi folks,

How would I go about taking a square sprite, and cutout a circle? I realize sprites are square, but I essentially want to turn a square image into a circle (erasing the rest of the sprite). This needs to be dynamic. I took a peak, but I did not see any hits on the forum...has anyone accomplished this already?

For example:

If I had an image of a black square, the resulting sprite would be a black circle on screen.

Thanks

You can put a black sprite with a round transparent hole in it on top of your square sprite.

Set blend mode on that black sprite with a hole to "Destination out".

Both sprites should be on a separate layer I think.

I made an example for another post, but it should give you an idea:

Interesting. I was under the impression that blends did not work across all platforms, is that correct?

What if I have something below and above the sprite? I see your background works well, but what if there is something ontop too ?

Very interesting concept. Ill need to play around with it, it has potential.

"What if I have something below and above the sprite?"

I haven't tested this much, but I think it only affects sprites on the same layer.

Hey —!

1. Put the image and the round mask on a layer. Mask over fill.

2. Set the layer Force own texture attribute to YES.

3. Set the mask Blending mode attribute to Destination in.

Hope this helps. Cheers!

You da man! Thank you <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile">

Got it working! Make sure when you do your transparent piece, it is a complete cutt-out. I had weird behaviour and found it was because the cuttout was not perfect color on the outside (it was not completely "hard")

Thanks again!

Glad to help!
