How do I create a wall from tunnel image.

Hi,

I have a huge image that i want to use in the game. The picture looks like a big tunnel that goes everywhere, and what i want to do is make the player move inside this tunnel while the rest functions as a wall.

The image looks like the walls from the nes game solar jetman.

Try creating invisible walls over the image

This thread sounds awfully similar to what you're trying to do. See if the guidance in there helps you out.
