【后端接口】宠物放生：放生的确认与资质返还

---宠物放生：两段确认防误操作
function PetRelease.confirm1(actor, petId)
    local player = class(actor)
    if not player then return false end
    local quality = Pet.qualityOf(actor, petId)
    if quality >= 4 then
        sendmsg(actor, 1, "高品质宠物需要输入放生确认码")
        setplayvar(actor, "HUMAN",
            "Release_" .. petId, os.time(), 0)
        return false
    end
    PetRelease.doRelease(actor, petId)
    return true
end

---二次确认后执行放生
function PetRelease.confirm2(actor, petId)
    local mark = getplayvar(actor, 2,
        "Release_" .. petId)
    if not mark or mark == "" then
        sendmsg(actor, 1, "请先点击放生按钮")
        return false
    end
    local quality = Pet.qualityOf(actor, petId)
    local refund = quality * 10
    PetRelease.remove(actor, petId)
    giveitem(actor, "宠物零食", refund)
    setplayvar(actor, "HUMAN",
        "Release_" .. petId, "", 0)
    sendmsg(actor, 1, "放生完成，获得宠物零食 x" .. refund)
    return true
end

---误放的保护：30 分钟内的撤销窗口
setontimerex(150, 60)
function PetRelease.undoCheck()
    for uid, record in pairs(PetRelease.recent) do
        if os.time() - record.at > 1800 then
            PetRelease.recent[uid] = nil
        end
    end
end

---撤销放生：30 分钟内可恢复
function PetRelease.undo(actor)
    local record = PetRelease.recent[actor:GetUserId()]
    if not record then
        sendmsg(actor, 1, "没有可撤销的放生记录")
        return false
    end
    PetRelease.restore(actor, record.petId)
    PetRelease.recent[actor:GetUserId()] = nil
    sendmsg(actor, 1, "宠物已恢复")
    return true
end
