In the scriptdraw function module, about animation options, what's the difference between "using_weapon_a"、"firing_a" and "attacking" ? And another, what does the conditionflag "MANUAL" mean? "ONCE" means only 1 time, but "MANUAL" seems 1 time and another time's first frame. If I wanna a 50 frames long animation's fragment from frame 10 to 20, what should I do if I don't have 3dsmax, is there any codes to control the animation in xml? Ah...I forgot. How to add switch_weapon function on an infantry squad such as the confessor_squad? Once I tried copy the firehawk's switch_weapon button and link to the single confessor unit. But it has bug that when I select secondary_weapon button it don't fire until I move them to another place by mouse. And sometimes it don't fire anymore, when I select to primary_weapon, it will throw grenade last time and then firing machine gun correctly.
