How to detect character not holding any items?

[VenusVapor]

Im trying to make it so that my character can charge with rmb when not holding an item but disable the ability to charge when holding an item. I used the same code that changed woodie's were actions and I could charge when "setspecialactions" was below "onbecamehuman" but now I dont get the option to charge at all. Any help is appreciated.

local function SetDefaultActions(inst)
inst.ActionStringOverride = nil
    if inst.components.playercontroller ~= nil then
        inst.components.playercontroller.actionbuttonoverride = nil
    end
    if inst.components.playeractionpicker ~= nil then
        inst.components.playeractionpicker.leftclickoverride = nil
        inst.components.playeractionpicker.rightclickoverride = nil
        inst.components.playeractionpicker.pointspecialactionsfn = nil
    end
        EnableReticule(inst, false)
end

local function SetSpecialActions(inst)
    inst.ActionStringOverride = nil
        if inst.components.playercontroller ~= nil then
            inst.components.playercontroller.actionbuttonoverride = Empty
        end
        if inst.components.playeractionpicker ~= nil then
            inst.components.playeractionpicker.rightclickoverride = ChargeRightClickPicker
            inst.components.playeractionpicker.pointspecialactionsfn = ChargePointSpecialActions
        end
        EnableReticule(inst, true)
    end

local master_postinit = function(inst)
	inst:ListenForEvent("unequipped", SetSpecialActions)
	inst:ListenForEvent("equipped", SetDefaultActions)
end
