I need help with crosshair changing

[jAckalWTs]

If player switch weapon to weapon from one of table, then run concommand
local shotgun =
{
"weapon_plasmacutter_bread", "weapon_doom3_shotgun", "weapon_crossfire44", "tfa_doom_ssg", "tfa_kf2_eviscerator", "weapon_q4_shotgun", "weapon_q4_shotgun_clip", "weapon_q4_nailgun", "tfa_ravager"
}

function player_crosshair_changing( )
if shotgun[GM:PlayerSwitchWeapon( player, oldWeapon, newWeapon )] then ply:ConCommand("set_crosshair quater_circle") end
end

PlayerSwitchWeapon returns a Boolean
You need to call player_crosshair_changing
Any player will be able to change their crosshair at any time
