well pal i may be able to help you if you tell me what those buttons do repreesent....however what i can do is to create a script for l2walker when those buttons for example contain the three kind of shot i can write a script that tells use this after 1,2 sec this and after 2,3 this and go again to the beggining...so is that for shots or for skills??
and of course i could add some parametres that you could modify as for example ::if mana>500:: or
::if mana>50%:: use bss etc.
