I was wondering if anyone can point me to some resources for some more complex structures and entities in Quake. I would like, for example, to make some strip lighting for parts of my first level. Unfortunately the entities for light sources all seem to be point light sources. I made a cylinder, squashed it and put a white texture one it for the model, and then i put an entity of "light" up.
Here's what it looks like atm, ideally it would be a flickering strip light and atm its a little spot light.

I'm guessing that I've got to use quakec and code up an entirely new entity for a strip light which defines its size and properties, and then insert this new entity into my level ie. light_my_strip_light? Is that about the gist of it or is there an easier way?
