option > control > set key & button >general . Default has weapon slot 1 to 8 with 1,-- to 8,-- .
I set weapon slot 1 to 1,-- & 2 to 2,--
Rest weapon slots are --,--
I notice that option > control > set key & button > on foot has 'scope zoom in' with wheel up,e and 'scope zoom out' with wheel down,q
But rolling scroll wheel up &cycles through all weapon .
I have tried to tell all settings. Hope , that makes it easier for you to point my mistake ?
Otherwise I should make a mod that does not allow player to keep any weapon other than pistol . Will that be easy ?
