My macro is a real godsend for me. It makes it so that when I play Point blank with a sniper rifle, the right mouse button performs 3 tasks at once. Here's what happens when you click it:

1) Automatic aiming: The macro immediately adjusts the target point to the opponent so that I can instantly aim.
2) Automatic shot: The macro also fires a shot when I press the right mouse button. It saves me time and makes shooting much faster and more efficient.
3) Quick change of weapons: The macro also automatically performs a change to a backup weapon if I don't have ammo or I don't have the opportunity to replenish them. This allows me to be always ready for any situation and avoid danger.

By the way, this is the third macro I'm creating to play Point blank. I set the sensitivity to 0.8 in order to achieve maximum accuracy and controllability of the sight.
