【框架设计】灵宠出战：出战位与助战位的切换逻辑

-- 灵宠槽位：出战与助战切换
local player = class(actor)
local function switchPet(player, petId, toSlot)
    local curSlot = getplayvar(player, "HUMAN", "PetSlot_" .. petId)
    if curSlot == "fight" and toSlot == "assist" then
        sendmsg(player, 1, 0, "出战中的宠物不能直接转为助战。")
        return
    end
    if tonumber(getplayvar(player, "HUMAN", "InCombat") or 0) == 1 then
        sendmsg(player, 1, 0, "战斗中无法更换灵宠。")
        return
    end
    setplayvar(player, "HUMAN", "PetSlot_" .. petId, toSlot, true)
    sendmsg(player, 1, 0, "灵宠已切换至" .. (toSlot == "fight" and "出战位" or "助战位") .. "。")
end

-- 灵宠属性：折算注入
local player = class(actor)
local function recalcPetBonus(player)
    local fightId = getplayvar(player, "HUMAN", "PetFightId")
    local assistId = getplayvar(player, "HUMAN", "PetAssistId")
    local fightAtk = tonumber(getplayvar(player, "HUMAN", "PetAtk_" .. fightId) or 0)
    local assistAtk = tonumber(getplayvar(player, "HUMAN", "PetAtk_" .. assistId) or 0)
    local bonus = fightAtk + math.floor(assistAtk * 0.3)
    setplayvar(player, "HUMAN", "PetBonusAtk", bonus, true)
    addbuff(player, 10091, 0, 0, player)
    sendmsg(player, 1, 0, "灵宠加成已刷新：攻击 +" .. bonus .. "。")
