Is there a way in LOVE to return the color values of a single pixel? I'm trying to set collision between a character and map areas (walls) using a bumpmap where black indicates passable areas and white indicates impassable areas.

Yeah, you have to create an imageData object from your file first:

That comes with a getPixel() method, which does what you want :)
