To execute this unique macro, you need:

1) Possess a weapon capable of firing without reloading (pistol, net, revolver, etc.). Make sure that you have such a weapon in your hands.
2) Make a right turn. Despite the fact that it is not necessary, such a turn will help you achieve a better result.
3) Watch for the delay between repetitions of the macro, otherwise it may lead you in the wrong direction where you need to go. You can set a delay of about one and a half seconds (you need to run tests for the exact value), but it is desirable to determine the time interval when the duck will end its flight. When the duck takes off to shoot back again, you will need to press the key again to climb even higher.
4) Please note - I do not guarantee that your duck will not fly away. If that happens, it's your own problem. Everything worked correctly in my tests, so if you have any problems, try to do everything again - suddenly you will succeed.
