Launch a ray and returns the result of the test : the intersection point or nil and optionally the object
note : only detects objects with physics collision enabled

point, object = rayHit(start, end)

or :

point = rayHit(start, end, object)

Example1, test the intersection with the full scene :

   function onSceneUpdate()
       start = {0, 0, 0}
       end = {100, 0, 0}
       point, object = rayHit(start, end)
       if point then
           print(point) -- print point
           print(getName(object)) -- print object name
       end
   end

Example2, test the intersection with an object :

   object = getObject("object")
   function onSceneUpdate()
       start = {0, 0, 0}
       end = {100, 0, 0}
       point = rayHit(start, end, object)
       if point then
           print(point)
       end
   end
