go to config.lua
and add Under: WEAPONRANGE = { -- range of cs2d weapons. e.g. [50] = 27 means wpnid 50 has range of 27 pixels. i should get around to change this to ingame ids some time.
[1] = 336,
[2] = 336,
and
Under: WEAPONWIDTH = { -- angular range of cs2d weapons. e.g. [50] = math.pi*2/3 means 120 degrees or 2pi/3 range of attack.
[1] = math.pi/12,
[2] = math.pi/12,
you should be able to hit monsters now.
