I'll start off saying my peace on how I hate anti-recoil that involves anologe movement. It highly inaccurate and causes more problems than good in my opinion.
If u want to make your own, it shouldent be that hard. Just pull up your rapid fire macro. Go to the RS anolog movent and start your RS anolog movement the first line in on the macro timeline, now drag it to the last bar your rapidfire ends on. Now all u have to do is drag the dot down just a little below the original dead center mark in the circle. Do this to both points (beginning dot & ending dot) trying to keep the dots consistent with one another.
This will be trial by error. Depending on what sensitivity level u play on will determine how u will have to adjust your downward anologe movement. If the gun still climbs up then u need to add a little more downward RS movement. If it climbs down when u fire then u need to adjust the anologe movement up more toward the center of the stick.
Now the crumy thing about anologe anti recoil is now u have canceled out the recoil climb u can now NOT aim up or down when firing. It will not let u. U can aim left to right when firing but not up and down. Another down side is when u hip fire its more sensitive. U will be quickly shooting at the floor. A on/off toggle would be ideal. Also if this is for COD AW I wouldn't even use it. With all the boast jumping in this game this application would only be ideal for very long shots across the map. Anything else would just be suicide.
Its a fairly easy macro to make it just takes good old testing to get it right. It doesn't require much downward movement to get it right. Just drop the center square box just a couple centimeters below the center mark keeping both dots (beginning and end) with equal coward pull. Test it and see if its still pulling up or down then slightly fine tune till its where u want it. I'm sure u will come to the same conclusion as I've stated and find that its more of a disadvantage than an actual game advantage.
