Y coordinate of collision data at a X coordinate

Hi Everyone,

I know I have been posting a lot but I was just wondering if anyone had any idea how to find the Y coordinates of collision data at a certain X coordinate?

Thanks,

simple. something like this should work:

-- example: hitTestLine ( 100, enemy1, 50 )  
-- returns: y-coordinate of object that hits the line  
  
-- lineX (imaginary line at x)  
-- theObject (object that hits the line)  
-- distance (trigger hit at distance to line)  
  
hitTestLine = function( lineX, theObject, distance )  
 local dist = distance or 10   
 if theObject.x \> lineX + dist or  
 theObject.x \< lineX - dist then  
 return false  
 else  
 -- print ("HIT!")  
 return theObject.y  
 end  
end
