How do I make an erasable picture.

Hello.

I'm looking for some assistance in making a game.

Basically I want to put a picture and then have erasable items over the top of the image. These can be erased by either clicking and dragging the mouse, or touching the area on a mobile.

Would be willing to pay someone to assist with this as it's for business and I want to test the software.

Thanks

It would consist of creating sprites with blendmode set to destination out on top of the erasable picture (which has to be in the same layer) and having the layer set to force own texture.

The concealed image would be on the layer below.

Do you have Skype?
