jobei

I have a normal picture of a parking lot that im using as my background. I also made a night vision goggle image (it's just a circle) I want to move the goggle around the picture and whatever inside the circle of the goggle will be green and whatever outside of the circle will be the normal background. Anyway know how to do this type of code?

I already have two background picture, one backgound is all green for the night vision part and I have the normal background
picture as well.

Let me know what you think
Made a little template for you combining alpha, colour multiplying and touch,
Move your finger around to use the night vision scope http://www.mediafire.com/?e36xhhwcwxi16g6

But this is how i would do it.

Mine works the same way as the platformer template you can open when you start GS, expect you drag it around and it is night vision green.

@jamieoneil
This is just a black screen with a translucent piece in the middle that you can drag around, He wanted something that the rest of the screen was normal but the circle was night vision, Like what I have done in the template I supplied

You'll have to do some trickery with blending modes.
