The Laser Detecting Code (cont)
OK that was easy, right? We can find out the exact numbers of the ship's left, right, top, and bottom sides using some simple algebra. Using them, we see if the laser shot's (x/y) values are inside that area.
Note: this refers to the object center point. THE PLUS SIGN.
You will notice on the laser the center point is NOT in the middle of it, but on
the front edge. So the code checks if the front edge of this laser is inside the
ship's boundaries. (Note Also: the Game Gun rotates the laser shot so that the
"plus" sign travels first.) You could easily ignore these finer
details and your laser detection would make no noticeable difference anyway. I
just like to be precise.
