Linked lists aren't difficult Though I don't know if there are restrictions in place with Lite-C, but at least the concept is fairly simple

I think I will need to check more than one entity at a time, and simply using c_trace will only return a single obstructing entity. I may have several trees blocking the view at once.

I am contemplating setting triggers on the trees that will trip when the player comes within a certain distance. I'm not sure how that will affect the speed of the game though.

Thanks for your help,
