How do you make it so a mob can see a certain object/mob though opaque objects?
... If you mean opacity = 0, its not too hard.
In response to JordanUl
No, I don't want to be able to see inside, I want to be able to see certain objects/mobs that are inside. For example, I want to be able to see what's IN a building, but not what's on the other side of it.

I don't know if see_infrared covers it, but I'm pretty sure the sight bits do.
In response to Foomer
Nope, I don't see anything that lets you see a certain object through walls.
