Relating to this question i was wondering if .NET has any libs (or a function) i can use to detect if one point collides with another.

I am not sure what angles i should use but is there some function like this

func(point src, rect target, angle, distanceOfVision, listPointOrRectOfWalls)

Pretty unlikely but i dont know a formula or how to start. Its a quick and dirty prototype. I am thinking of writing the func about but dropping angle and just make line of sight a rectangle and check if any points is between src and target.
