---宠物装备：三槽位的设计
local PET_SLOTS = { armor = 1, ornament = 2, weapon = 3 }

function PetEquip.wear(actor, petId, slot, makeIndex)
    local player = class(actor)
    if not player then return false end
    -- 宠物等级解锁槽位：10/20/30 级各开一槽
    local petLv = Pet.levelOf(actor, petId)
    local needLv = slot * 10
    if petLv < needLv then
        sendmsg(actor, 1, "宠物 " .. needLv .. " 级解锁此槽位")
        return false
    end
    PetEquip.equip(actor, petId, slot, makeIndex)
    sendmsg(actor, 1, "宠物装备已穿戴")
    return true
end

---宠物装备的属性加成与面板刷新
function PetEquip.recalc(actor, petId)
    local atk = Pet.baseAtk(actor, petId)
    for slot = 1, 3 do
        local eq = PetEquip.of(actor, petId, slot)
        if eq then
            atk = atk + eq.atkBonus
        end
    end
    Pet.setAtk(actor, petId, atk)
    sendmsg(actor, 1, "宠物攻击更新为 " .. atk)
end
