BBot - The best bot of the world

Hello fellas, I am now usin bbot for my third year, and I havent understood the way macro works, well enough of that speech, I am now asking you guys if you know how to make this one to work .... I am playin on a custom map and I used a script Dexter posted but it doesnt seem to work....... this is the macro script for manarune


1000 {manarune} Self.Mana%<67 Target.Self=1 Target.Shoot(ID)=3159 <- doesnt work, please help me to get one which works.

I believe this macro is old, the form of writing has changed a bit
