Force Field Shader

Here, I'm making the intersection with other objects visible by subtracting the screen position from the scene depth. There is an offset, so you can control the strength of the intersection. I also needed to clamp the result of the nodes because the alpha expects a number between 0 and 1.

After making the intersection, I wanted there to be an outline for the rest of the force field. I did this by adding a Fresnel effect together with the intersection.

The last part of my shader is a scrolling texture. I did this by using the tiling and offset node so the texture repeats itself and moves in a direction. I can control the speed and size of this by multiplying it with time and a variable I can change in the inspector.
