Thread: need a bump in the right direction

if i have 2 sets of coords, say 50,50 and 100,100.
and then an array of square shaped obstacles between the two points

for (int i = 0; i < arrayOfStuffInTheWay.size(); i++) {
   int x = arrayOfStuffInTheWay.get(i).getX();
   int y = arrayOfStuffInTheWay.get(i).getY();
   int width = arrayOfStuffInTheWay.get(i).getWidth();
   int height = arrayOfStuffInTheWay.get(i).getHeight();
 
if (theBounds of the object are touch the coordinates of the line){
   //compare the range between x+width to the line
   //compare the range between y+height to the line
   // then do some logic and return true or false if there is a line of sight obstruction
   }
}

i guess i need to know how to get the line .. and get it efficiently. thanks for any input u can give in advance
